Choosing the right projector is crucial when creating an immersive home entertainment experience. As Home Cinema Projectors become more popular every day, it's important to consider factors like brightness, resolution, connectivity options, and overall performance to ensure you choose a projector that meets your needs and expectations. One of the home projector's key features is its resolution. The 1080P Home Projector delivers Full HD images, delivering clear and detailed visuals perfect for watching movies and sports events. In addition to resolution, consider the brightness of your projector. A projector with a higher lumen output will provide a brighter image, making it suitable for ambient light or rooms with a larger viewing area. Connectivity options are another important factor to consider when choosing home projectors for your home. Look for a projector with multiple input ports, such as HDMI, USB, and audio jacks, to easily connect all your devices, including laptops, gaming consoles, and streaming devices. This versatility allows you to switch seamlessly between different sources and enjoy a variety of content on the big screen. With convenient wireless connectivity options, you can also stream content from your smartphone or tablet directly to the projector for added flexibility. With the right combination of features and specifications, you can create a home theater setup that rivals the traditional movie theater experience. Whether you're a movie buff, a gamer, or just looking to upgrade your entertainment system, a quality projector can transform your living space into a versatile and immersive entertainment center.

When choosing a projector suitable for home use, you mainly need to consider the following points: Brightness: Choosing a projector with higher brightness can ensure that the image can show good results in a bright environment. Generally, the brightness of a home projector is more than 2,000 lumens. Resolution: Resolution determines the clarity and detail performance of projection. For home use, you can generally choose a 1080P Home Projector. A high-resolution projector can present clearer images. Projection ratio: Generally, the widescreen projection ratio of 16:9 is more suitable for family viewing. It can present a wider picture effect and is more in line with the needs of family viewing. Projection distance and size: The shorter the projection distance, the larger the projection size, so that a larger picture effect can be obtained in a smaller space. You can choose a projector according to the limited space in your home to get the best viewing effect. Interfaces and functions: Generally speaking, home projectors are equipped with HDMI interfaces, USB interfaces and other interfaces to facilitate the connection of various devices, such as TVs, computers, game consoles, etc. Based on the above, you need to consider many factors when choosing a suitable projector. In the end, you still need to make a choice based on your home viewing needs and space conditions.

Home projector is a device that facilitates users to watch movies, presentations or play games at home. When choosing a home projector, you are often faced with the dilemma of choosing LCD (Liquid Crystal Display) technology or DLP (Digital Optical Processing) technology. Common home projectors include mini projector, 3D projector, wireless projector, laser projector, 4k home Projector, etc. LCD technology is a technology that produces images through a liquid crystal display. LCD home projectors generally have high brightness and contrast, are relatively low cost, have the advantages of long service life and lower power consumption. Users can use it for a long time without worrying about equipment damage or high energy consumption. LCD technology also has some shortcomings. For example, the image resolution of an LCD projector may be lower, the display panel may produce a "screen door" effect, and there may be some blurring or image retention issues when processing fast moving images. DLP technology is a technology that produces images through micromirror columns and laser display. DLP home projecror has higher image resolution and better color reproduction capabilities, without the "screen door" effect and image retention problems like LCD projectors, and has a faster response speed. Able to present clearer and more detailed images. Suitable for watching high-speed sports videos or playing competitive games. DLP technology also has some shortcomings. DLP projectors typically have lower brightness and contrast, are relatively more expensive, and may have a relatively short lifespan. No matter which projector technology you choose, the final choice of home projector will depend on your personal needs and preferences.

Common projection technologies currently on the market include LCD projection, DLP and LCOS. LCD Home Projector are low-cost and suitable for home use; DLP Home Projecror have good color performance and image details, suitable for cinema-level viewing; LCOS projectors combine the advantages of LCD home projector and DLP home projecror. There are several factors to consider when choosing the right Home Projectors: 1. Purpose: Determine the main purpose for which you will buy the projector. Is it for home theater, gaming, presentations, or something else? 2. Resolution: The resolution of the projector determines the clarity of the image. Common resolutions are 720p, 1080p and 4K. Choose the appropriate resolution based on your needs. 3. Brightness: Brightness determines the display effect of the projector under different lighting conditions. If you plan to use the projector in a bright environment, it will be better to choose a product with high brightness. 4. Contrast: Contrast determines the degree of difference between black and white in a projected image. Higher contrast provides clearer, more vivid images. 5. Projection distance: Choose the appropriate projection distance according to your home layout and projection needs. The farther the projection distance, the larger the projected image. 6. Interfaces and Connectivity: Make sure the projector has the appropriate interfaces for your device, such as HDMI, USB, VGA, etc. Also consider whether it supports wireless connectivity. 7. Noise: Noise is the sound produced by the projector when it is working. Choosing low-noise products can provide a better viewing experience. 8. Brand and price: Choose a reliable brand and a reasonable price range. Refer to other users` reviews and professional reviews to choose products with higher price ratios. You also need to consider the projector`s acoustics, interfaces and functions. The sound effect is directly related to the viewing experience. You can choose a projector with speakers or connect external audio equipment; in terms of interfaces, consider whether the projector has common interfaces such as HDMI and USB to facilitate the connection of different devices; in terms of functions, such as whether it supports Wireless projection, 3D projection, etc., you can choose a Home Theater Projectors with corresponding functions according to your personal needs.

2. Chip Determine resolution and quality The vast majority of household projectors use DLP display technology, so we have to mention DMD chips, which are the core of DLP display technology. Different projectors on the market have different resolutions and picture quality, mainly depending on the size of the DMD chip. The common sizes of DMD chips are: 0.23, 0.33, 0.47 and 0.65 (unit: inch), among which 0.33 and 0.47 DMD are very common. The larger the chip size, the higher the resolution, the better the picture quality definition, generally 0.33 is 720P resolution, and 0.47 is 1080P resolution. 3. Lens Determine the close distance between the projector and the screen The main function of the lens is to project and magnify the picture. The material selection is the best glass lens. When it comes to the lens, the focal length must be mentioned. Different projectors have different focal lengths, which are generally divided into general focal length, short focal length and ultra-short focal length. three kinds. The throw ratios between them are different. For example, at the same distance of 2m, the general focal length can project an 80-inch screen size, while the short focal length can project a 100-inch screen size, and the ultra-short focal length can reach a 100-inch screen size with only 40cm size. The commonly used projection ratio is 1.2:1. The smaller the throw ratio, the larger the screen size can be transmitted at a smaller distance.

The projectors on the market have different prices, good and bad, and the parameters inside are also dazzling. Not only the owners, but many designers are at a loss. Designers want to understand, but it is actually very simple. Just avoid the screen large, poor picture quality, and low brightness, then it is necessary to grasp these core indicators. 1. Light source The type and brightness of the light source Projector light sources generally include LED light sources, high-pressure pump bulbs, laser light sources, and xenon lamps. LED light source Its advantage is that it can be used for a long time, but its disadvantage is also obvious, that is, the brightness is very low, so it can only be used at night or in a dark environment. High pressure pump light source The brightness is very high, so it has a strong heating phenomenon, so it needs to be equipped with a strong heat dissipation device, resulting in greater wind noise. In addition, its service life is relatively short. Xenon light source High brightness, short life, expensive Laser light source At the same time, it satisfies the two advantages of long service life and high brightness, and is an ideal choice for projector light sources. The brightness of the projector's light source is usually expressed in "ANSI lumens". The higher the value, the brighter the brightness. Generally, household projectors usually choose a projector with a brightness of at least 2000 ANSI lumens to ensure that no matter at night or in bright daytime, All can be high-definition high-brightness picture experience and effects. In addition, light source lumens ≠ ANSI lumens The light source lumen is the initial brightness without any attenuation, and the ANSI lumen is the final actual brightness value.

After talking about the LED light source, let's talk about the laser light source. The brightness of the laser light source is higher, and the picture quality effect will be better controlled. The laser light source can directly select the red, green and blue three-color laser generators of specific bands according to the needs. The three-color laser light source can reach 100% BT.2020 color gamut coverage, which exceeds the color gamut of OLED TV and QLED TV. limit of coverage. Therefore, the imagination space of the three-color laser light source is very large, and the range that can undertake future viewing needs is also wider. The light sources of laser projectors are divided into several categories. Among them, monochromatic lasers use a single blue laser to excite yellow and green phosphors on the fluorescent color wheel, and then separate red, green, and blue light through a prism, and finally combine to form other colors. , and then pass through a filter to refine the color. The monochromatic laser light source itself does not have red light and green light, so there will be color loss. If you want brightness, you lose color; if you want color, you lose brightness. This is why many people do not recommend single-color or two-color light sources. In contrast, the three-color laser light source does not have the problem of brightness and color, so many players used in high-end theaters use three-color laser light source. However, the three-color laser light source also has the problem of speckle, which is generally eliminated by vibrating screens in movie theaters. Household level is eliminated by reducing power. Through the above content, we can see that the three-color laser light source will be a "future", but the problems of speckle and high price are also problems we have to face. If any brand can solve these two problems, then the projector with three-color laser light source will definitely become the new mainstream.

LED is one of our most common light sources. The LED lights used in projectors are customized high-power light sources, and the price is much higher than that of LED light sources for lighting. But even so, the cost of LED light sources is relatively low, much cheaper than laser projectors. In addition, three different colors of red, green and blue LED light sources can be used to construct a projection light source, and different colors can be presented through three-color mixed light, which can easily cover the sRGB color gamut. Therefore, many mainstream projectors currently use LED light sources. In the early days, due to technical limitations, the brightness of LED light sources was not ideal. However, with the development of science and technology, the brightness of LED light sources has been able to meet the daily needs of users in recent years. The brightness of flagship phones basically exceeds the threshold of 2000 ANSI lumens, and the brightness of many projectors even exceeds 3000 ANSI lumens. Therefore, it is reasonable for LED light sources to become the mainstream.

When you choose a projector, what parameters do you mainly look at, brightness or configuration? If it were me, I'd look at the light source first, then brightness and configuration. It`s just about the light source of the projector. Few people mention it. The light bulbs, LEDs, and lasers are familiar to everyone, but many people don`t know the actual differences between these light sources, and don`t understand their advantages and disadvantages. So, I will take a brief inventory today to see which light source is suitable for "future use". While meeting the current viewing needs, it will not be outdated in N years. The following mainstream projection light sources: At present, with the development of projector light sources, we have experienced three major categories: bulbs, LEDs, and lasers. Among them, the light bulb machine was widely used in the early years because of its short life, expensive follow-up maintenance, mediocre display effect, and many unstable factors. Later, it was gradually replaced by LED light sources. Of course, there are still some brands that use bulb light sources, but most of the projectors with bulb light sources are commercial and office-based, and relatively few for home use. At present, the mainstream projector light source is LED light source. Most of the high-end and low-end products on the market use LED light source. Speaking of LED light sources, everyone comes into contact with them every day. It's just that the LED light source of the projector is different from the LED light source in our life. It uses a customized light source, and its brightness is dozens of times higher than that of the daily lighting source, or even higher. The laser light source is relatively high-end, its brightness is high, and it is not at the same level as light bulbs and LEDs. There are also many kinds of laser light sources, mainly monochromatic lasers, two-color lasers and three-color lasers.

Have you noticed that after a period of use of the projector lens, stubborn dust will adhere to the surface, which will affect the projection quality. Therefore, it is necessary to clean the lens in time to prolong its service life. So, how do we clean the lens of the projector? 1. Cleaning tools Lens paper or cloth: Choose lens paper or cloth that is soft, lint-free, and lint-free, and the cloth can be used after repeated cleaning. Lens cleaning fluid, choose a cleaning fluid that can be used to deal with oil stains and is highly volatile, so as to avoid secondary pollution to the lens. Blowing balloons: choose soft, elastic, and large blowing balloons. The blowing balloons can be reused after repeated cleaning. Cotton swabs: Choose cotton swabs with long and neat fibers. It is best to prepare some large and small ones to deal with different situations. 2. Cleaning steps After preparing the tools, you can start to wipe the lens, step by step, 4 easy steps, and return you a brand new lens! 1. Blow up a balloon Use a blower to blow off the relatively large particles of dust and sand on the outer surface of the lens, and reduce the large particles to avoid directly wiping the worn mirror surface. Remember not to blow the lens directly with your mouth. The result of blowing the lens directly will only make the saliva corrode the coating of the lens. 2. Second cleaning with lens paper Use lens tissue to carefully wipe off any stubborn dirt that hasn't been blown away. Be careful when wiping, wipe gently, and pay attention to wiping in one direction, not wiping back and forth or in circles, so as not to cause hard damage to the lens coating. 3. Cotton swab deep cleaning Use a cotton swab to stick a little lens cleaning solution, and remove the dust and stains that are tightly attached to the lens by sticking or picking. 4. Dry the lens Use a lens cloth to wipe gently in one direction from the center outward until the lens is completely clean. How about it? After reading this guide, do you think it is super simple? In the future, you will not be afraid of damaging the lens when cleaning the projector lens! However, when we use the projector on a daily basis, we should also take good care of it so that it can accompany us for a longer time~

1. Brightness Brightness is the intensity of light (in lumens (lm)) that the projector outputs onto the screen. 2. Projector projection light effect The ratio of projector light output to power-on power in lumens per watt (lm/W). 3. Power-on status The status of the projector being connected to power and generating an image. 4. Power on The active power measured when the projector is powered on. 5. Passive standby state When the projector is connected to the power supply, neither sound nor image is produced, but it can be switched to the off or on state through the remote control or other external signals. 6. Passive standby power The active power measured by the projector in passive standby state, this power should be less than or equal to 0.50W. 7. Noise requirements When the projector is working normally, for products with a mass greater than 2.0kg and less than 5.0kg, the noise should not be higher than 36dBA; for products with a mass less than (including) 2.0kg, or a product with a mass greater than (including) 5.0kg and less than 20kg, The noise should be no higher than 40dBA; for products with mass greater than (including) 20kg, the noise should be no higher than 43dBA. 8. Projector energy saving evaluation value See Table 1 for the minimum projected light efficiency and energy efficiency levels allowed for energy-efficient projectors. The minimum projection light efficiency required by the energy-saving evaluation value of the projector is Level 2 of the energy efficiency level in Table 1, and at the same time, it must meet the requirements of the passive standby power limit value, that is, less than or equal to 0.50W.

According to the different daily usage, we can divide projectors into portable projectors, desktop projectors and fixed installation projectors. picture A projector weighing less than 2 kg is generally defined as a portable projector, which is comparable to the weight of a laptop. Portable projectors have become the first choice of mobile business users for mobile business presentations because of their small size, light weight, strong mobility, and easy portability. At the same time, portable projectors are also a better choice for home use. Projectors with complete video ports, 16:9 aspect ratio and moderate brightness, suitable for playing movies and high-definition TVs, have become the main products chosen by families. Desktop projectors are popular models for everyday use and can be widely used in offices, schools, and entertainment venues. Because of its moderate design volume, good heat dissipation and dustproof system, wide range of resolution options, good expansion performance, and suitable for installation or short-distance movement, it is a veritable performance responsibility. According to the actual use needs of users and their specific use occasions, the projector can choose the ceiling installation method, that is, the fixed installation method. When adopting this installation method, attention should be paid to dust prevention and heat dissipation. According to different working methods, projectors can be divided into different types such as CRT, LCD, DLP, etc. CRT is the English abbreviation of Cathode Ray Tube (Cathode Ray Tube). As an imaging device, it is the earliest and most widely used display technology. The CRT technology is mature, the displayed images are rich in color, and the reproducibility is good, but its important technical indicators, image resolution and brightness, mutually restrict each other, which directly affects the brightness value of the CRT projector, and the operation is complicated and the body is large. Therefore, the current market It is rare to see projectors with CRTs. LCD is the English abbreviation of Liquid Crystal Display. Its imaging principle is to use the photoelectric effect of liquid crystal, that is, the arrangement of liquid crystal molecules changes under the action of an electric field, thereby producing images with different gray levels and colors. LCD projectors can be divided into LCD panel projectors and LCD light valve projectors. The former is the main product in the current projector market. Because LCD projectors have better color reproduction, high resolution and good brightness uniformity, they are the mainstream products in the current projector market. DLP is the English abbreviation of Digital Light Processor. DLP projectors use DMD digital micro-reflectors as light valve imaging devices. After the beam passes through a high-speed rotating trichromatic lens, it is projected onto the DMD, and then passes through the optical lens. Projecting on a large screen completes image projection. Generally, an ordinary DLP projector uses a DMD chip, which can achieve a small and compact shape. Many mini projectors under 2 kg on the market are DLP type. In addition, another advantage of the DLP projector is that the image is smooth, the contrast is large, and the contrast ratio is high, and the reflection technology makes the DMD chip absorb less energy and has good high temperature performance, which is the first choice for home theaters.

A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV or the Internet through different interfaces to play the corresponding image or video signal. In recent years, with the continuous development of multimedia technology, the application of projectors has become more and more extensive. At present, projectors have been widely used in homes, offices, schools and entertainment places. According to different working methods, projectors can be divided into (CRT) cathode ray tube projectors, (LCD) liquid crystal display projectors, (DLP) digital light processing projectors, etc.; according to different ways of use, projectors can be divided into portable projectors projectors, desktop projectors, and fixed-mount projectors. Faced with a dazzling array of products on the market, how should we choose? 1. Relevant certification of projector products The projector product is a product in the 3C catalog, that is, the product needs to obtain the 3C certificate and affix the 3C logo on the product before it is allowed to leave the factory, sell, import or use in other business activities. Therefore, when purchasing projector products, be sure to check whether the information on the 3C certificate is consistent with the purchased product information, including the manufacturer, manufacturer, product model, specifications and other information. Projector products can apply for energy-saving certification. Products applying for energy-saving certification must first obtain 3C certification. Products that can obtain energy-saving certification can generally control the power consumption of the product when it is working, and can enter a low-energy consumption state when the product is not working, effectively saving energy and reducing emissions.

The size of the projector determines the viewing effect and experience, and designers need to grasp these dimensions: 1. The best viewing size for a projector If the projector is set in the living room, the optimal viewing distance is calculated by the following formula: the length of the curtain * 0.87 = the optimal viewing size For example, if the length of the curtain is 2500mm and 2500*0.87, then the distance between the sofa and the curtain is ≈2200mm. 2. Projection size of the projector Different projector lenses are different, so their throw ratios are also different, and the throw ratio is controlled at 1.2: 1 is the best. 3. The height requirements of the curtain Mainly consider the viewing height and the height from the ground. The horizontal angle of the human eye looking up at the screen is generally controlled within 15°. The average person sitting on the sofa is about 1050mm off the ground and the angle is 15°. The height from the center of the curtain, that is, the height of the curtain viewed by the human eye. Generally, it is through: the height of the floor - the distance from the center of the curtain to the top surface - half of the height of the curtain, and this formula gives the height of the curtain from the ground.

The projectors on the market have different prices, mixed with fish and dragons, and the parameters inside are also dazzling. Not only the owners, but many designers are confused. If the designers want to understand, it is actually very simple, as long as they avoid the picture Large, poor picture quality, low brightness, then it is necessary to grasp these core indicators. 1. Light source Type and brightness of light source: Projector light sources generally include LED light sources, high-pressure pump bulbs, laser light sources and xenon lamps. LED light source: Its advantage is that it can be used for a long time, but the disadvantage is also obvious, that is, the brightness is very low, so it can only be used at night or in a darker environment. High-pressure pump light source: The brightness is very high, so it has a strong heating phenomenon, so it needs to be equipped with a strong heat dissipation device, resulting in a large wind noise. In addition, its service life is relatively short. Xenon light source: high brightness, short life and expensive. Laser light source: At the same time, it meets the two advantages of long service life and high brightness. It is an ideal choice for projector light source. The brightness of the light source of the projector is usually expressed in "ANSI lumens". The higher the value, the brighter the brightness. Generally, household projectors are usually selected with a brightness of at least 2000 ANSI lumens to ensure that no matter whether it is night or bright during the day, All can be high-definition and high-brightness picture experience and effects. In addition, light source lumens ≠ ANJI lumens, light source lumens is the initial brightness without any attenuation, and ANSI lumens is the final actual brightness value. 2. Chip Decide on resolution and quality Most of the projectors used in home use are DLP display technology, which has to mention the DMD chip, which is the core of DLP display technology. Different projectors on the market have different resolutions and picture quality, mainly depending on the size of the DMD chip. Common sizes of DMD chips are: 0.23, 0.33, 0.47 and 0.65 (unit: inches), of which 0.33 and 0.47 DMD are very common. The larger the chip size, the higher the resolution and the better the picture quality. Generally, the resolution of 0.33 is 720P, and the resolution of 0.47 is 1080P. 3. Lens Determines the distance between the projector and the screen The main function of the lens is to project and enlarge the picture. The best material is glass lens. When it comes to the lens, we have to mention the focal length. Different projectors have different focal lengths. They are generally divided into general focal lengths, short focal lengths and ultra-short focal lengths. Three, the projection ratios between them are different. For example, the same distance is 2m. The general focal length projects an 80-inch screen size, while the short focal length can project a 100-inch size, and the ultra-short focal length can be achieved with only 40cm. 100 inches in size. The commonly used throw ratio is 1.2:1. The smaller the throw ratio, the larger the picture size can be transmitted at the smaller distance.

At present, in terms of absolute share and scale, projectors cannot replace TVs, but it is an indisputable fact that more and more consumers choose projectors. It may be a supplement to color TV, and it is also unique in some life scenarios. After all, the projector can both walk into the living room and walk out of the living room, which is a more "life-like" trend. For example, the current growth momentum of projectors is partly due to the special scene of camping - the body is portable, the screen is huge, and equipped with functions such as automatic correction, whether it is a family outing or a gathering of friends, the projector can be used in the outdoor environment. Although the overall size of the color TV market is declining, the share of the sub-category of game TV is increasing, and the premium capacity is considerable. Similarly, there are more and more projector brands that capture the specific needs of consumers, and some of them have made the size of the projector so that it can be lifted with one hand. This means that it is more likely to have explosive genes in the outdoor travel scene. From the current trend, projectors are more and more like a category between portable smart devices such as mobile phones and tablets, and large smart devices such as TVs. It's just that as a display hardware, it emphasizes spreading around the family scene and extending the market outward. Perhaps, for projectors, this special period is called the "precipitation period" more appropriately. When the category education is initially completed, the core problem is that if the scene is always limited to the living room, content and ecology have no new ideas, then the projector is almost destined to be "involved" in the infinite war. On the contrary, drawing vitality from the needs of consumers will make the projector brand go further.

1ANSI lumens≈0.8ISO lumens, that is, 1000ANSI lumens≈800ISO lumens If you encounter two products that are marked with ANSI lumens and ISO lumens respectively, you can use this conversion formula to convert them into unified units for comparison, and convert the data values into unified units for comparison. D. In addition, you can also find this rule. In the field of use, Japanese projectors focus more on ISO lumens of the International Organization for Standardization, such as Epson, Panasonic, Leli, Sony, etc.; while European and American products focus more on ANSI lumens, such as Kotaku. TV, Barco, ViewSonic, etc. However, in the market, most projector products have high ANSI indicators. It is recommended that in addition to comparing the values when purchasing, you should actually turn on the projector to see the brightness effect of different projectors. Projector brightness tips The use of high-brightness projectors in a small area will cause dazzling eyes, make the audience's eyes tired, and even lead to red, swollen and tearful eyes after long-term viewing. Therefore, it is recommended to choose a projector with suitable brightness according to the size of the use environment to avoid wasting resources. Don't try to use high brightness projectors at low brightness (to avoid glare), otherwise the picture will lose contrast or color saturation and the picture will be very ugly. In the same way, do not turn up the brightness of the projector with low brightness. The best brightness is the factory default brightness of the projector. Under this setting, the projection effect is the best.

At present, there are two types of markings for projector brightness standards in the international market, ANSI lumens and ISO lumens. When purchasing projectors, merchants will also use the brightness values of the products as comparison data to introduce the advantages of each product. But there may be information withholding when introducing ANSI lumens and ISO lumens. At this time, if you do not know the specific difference between the two, the probability of being pitted is high. ANSI lumens and ISO lumens are the projector brightness standards specified by two different associations of organizations. A method developed by the American National Standards Institute for measuring the luminous flux of projectors. According to the "nine-point" measurement method, the distance between the projector and the screen: 2.4 meters, the screen is 60 inches, use a light meter to measure the illuminance of each point on the nine intersection points of the "field" shape of the screen, multiply the area, and get the projection The brightness of the 9 points of the screen; the average value of the brightness of the 9 points is ANSI lumens. ISO lumens is a variety of brightness measurement standards for projectors stipulated by the International Organization for Standardization; it is an international standard. The ISO21118:2012 document specifies various standards for projectors, including projector brightness detection standards and technical terms. , noise measurement, etc., are the standard documents for more professional projector production and testing in the world. Summary: ANSI only stipulates the size of the measurement screen of "60 inches", but ignores the projection distance of projectors with different focal lengths, and ignores the air loss. And "ISO" takes these factors into account. Compared with ISO lumens, the measurement requirements of ANSI lumens are slightly lower, so from a professional point of view, ISO lumens is more scientific and more valuable.
