CNET puts the projectors through a strict and neutral test process that ends with more than two decades of projector reviews. We use special testing tools including a C6 HDR 5000 colormater, a Minolta LS -100 Luminance Meter and an AMC CA 813 Illuminance Meter. Data is collected and is assembled by The portrait shows the final to Calman Software, which helps us to evaluate in every piz we have reviewed. Each lamp-based projector is rare in 2025, “burns” 50 hours before the measurement. All projectors are initially set up using their most accurate color temples and colorful modes. The test patterns sent from a portrait display Videfourge Pro 8, then used to adjust the settings of different imagery so that the projector looks the best before measuring and evaluating. The contrast ratio is measured in each lamp and iris mode (when available). Once the projectors are fully set up and measured purposefully, we watch a variety of content, including TV, movies and games, both themselves with the projector and two direct competitors side by side.
In a broaderness, we are looking for the quality of the three images: the opposite ratio, the overall light output and the reproduction of the color. The contrast ratio is the most important part of any projector’s performance. This is the difference between the darkest part of the image and the brightest. Specific TV technologies like OLED can create a black that is the actual absence of light, no projector technology can do it. So the ratio against the projector is much lower. It is a washing and the difference between the “flat” image and it is a lifetime and “pops”. A better projector will have a ratio against a measure of thousands. Mostly between 500 and 1000: 1. The ratio between all the projectors measured in the last few years is the ratio of 468: 1 and averaged by several high -priced projectors, 876: 1.
Light output is the second most important element, because it is not only how bright the image will appear on your wall, but how big you can produce. Most modern projectors are significantly brighter than the projectors from 10 years ago. We measure the brightness per square meter (CD/M2) in the candles and then convert the comparison to the approximate lumens for ease. It is important to note that we use the most accurate color temperature mode for the comparison of our brightness but we note that the lesser-right mode is significantly brighter. Most of the projectors we test are between 1000 and 2,000 lumens, battery -powered models are much lower and some specialized projectors are more. The average brightness of the projectors we have measured in the past few years is 901 Lumens.
The accuracy of color is the last major cause. No projector can really take advantage of HDR or wide color gum, but some can do more than others. Generally, we are satisfied with the right color, but a bonus to add HDR effects. Most home theater projectors we test are fairly perfect. Budget models, which are brilliant than everything and prioritize PJS in the projector space, often have wild colors that result in the resulting very unnatural image.
Other factors such as video processing and HDR processing are evaluated in viewing tests. They are rarely the main reason for the projector’s performance, but some models still use problems that are problematic old chips.
The best projector will have a high contrast ratio, high brightness and great color. They are difficult to do at the same time, but as long as the balance works and it looks better at the same price than its competitors, it is the winner.
