All the projectors we review in CNET go through the same testing process that includes objective measurements and side -by -side symptomatic diagnosis. I’ve been reviewing projectors for more than 20 years and I have used one (okay, many people) as my main “TV” since I started reviewing them. I also train the Imaging Science Foundation and train at the National Institute of Standards and Technology to measure the display properly. I use special test equipment, which includes a C6 HDR5000 colorful meter, a monolta LS-100 Luminance meter and AEMC CA813 Illuminance meter. Data is collected and deposited by portrait display callman ultimatic software. All projectors are initially configured using their highly accurate color temperature and colorful methods. Test samples sent from a portrait show the video Oforj Pro 8K, then used to adjust different image settings so that the projector looks excellent before measurement and diagnosis. On the contrary, the ratio is measured in each lamp or LED/laser and Irus mode (when available). Once the projectors are fully configured and objectively measured, we see a variety of content, including TV, films and games, both with the projector, and two direct rivals as well.
With 4K projectors, such as portable and other home theater projectors, I am looking for three most important aspects of the picture: contrast ratio, overall light production and color regeneration. On the contrary, the proportion is the most important part of the performance of any projector. This is the difference between the darkest part of the image and the brightest. Although some TV technologies, such as OLED, can create a black that is the real absence of light, no projector technology can do so. Therefore, the contrary to the projector is very low. It is a washed out and “flat” icon and a life that is more lifetime and “Popes”. Improved projectors will have a proportion of the opposite in the thousands. Most are between 500 and 1000: 1. In the past few years, the middle dispute proportion for all these projectors is 468: 1, and on average, which has been hit by several high -cost projectors, is 876: 1. Overall, the production of light, which is measured in the lemon, not only how bright the icon is, but how large you can make it and still has a viable theory. The difference between some lemons does not matter, but there may be a difference between several hundred madh, boring image and really popped image. The color is a complex topic, but after years of testing, which includes dozens of “face” with non -tissue and non -reviewers, the correct color almost always wins on the under or overres. Extremely accurate projectors develop a lifetime colors that are very natural to look.
Lightoutput is the second most important factor, because it not only looks bright the picture on your wall, but also how big you can create. Most modern projectors are also significantly bright with 10 years ago projectors. We measure the brightness in the Candyls per square meter (CD/M2) and then turn into a LL Lemon of ease of comparison. It is important to note that we use the extremely accurate mode of color temperature to compare our brightness, but we will note that when the low drawer mode is significantly bright. Most of the projectors we test are between 1,000 and 2,000 lemons, battery -powered models are very few, and some special projectors are even higher. The average brightness for the projectors we have measured over the past few years is 901 limbs.
Color accuracy is the last important factor. No projector can really benefit from HDR, dolby vision or a wide color game, but some can work more than others. Generally, we are satisfied with the correct colors, but adding HDR effects is a bonus. The domestic theater that most projectors we do are quite accurate. Budget models, who prefer the brightness over everything, are often inaccurate with those from visitors to projector space, which results in the most unnatural image.
Other factors, such as video processing and HDR processing, are estimated in viewing tests. These are rarely an important factor in the projector’s performance, but some models still use old chips with problems.
The best projector will have the opposite proportion, high brightness and great color. It is difficult to do at the same time, but as long as the balance works and it looks better than its rivals at a similar price, it is a winner.
