The best 4K offer for 2025: It was tested and reviewed by experts

All display devices we review in CNET passes in the same test process that include objective measurements and personal evaluation side by side. I have reviewed the exhibition devices for more than 20 years and used one (well, a lot over the years) as a major “TV” since it started reviewing it. Me too Accredited Science Science Foundation And the training in National Institute for Standards and Technology To properly measure the offers. I can use specialized test equipment, including C6 HDR5000 COLORIMETER, the Minolta LS-100 lighting scale and AEMC CA813 scale. The data is collected and collected by Display the image as the final words programming. All display devices are initially prepared using the color temperature modes and the most accurate. Test patterns are then used, which are sent from a video displaying video Pro 8K, to adjust different photo sets, so that the display appears better before measurement and evaluation. The contrast ratios are measured in each lamp or LED/LASER and IRIS (when available). Once the display devices are completely prepared and objectively measured, we see a variety of content, including TV, movies and games, both with the display on its own, and compare along with two direct competitors.

With 4K displays, such as mobile displays and other home theater display devices, I am looking for the three most important image quality aspects: The percentage of contrastTotal additional output and color reproduction. The contrast ratio is the most important part of the performance of any display device. It is the difference between the darkest part of the image and the shiny. Although some TV technologies, such as OLED, can create black and is the actual absence of light, the technology of the display can not do this. Therefore, the display rates are much lower. It is the difference between washed and “flat” image and those that are lifelong and this is “fixed organic pollutants”. The best display devices will have a calculated variation in thousands. Most of them are between 500 and 1000: 1. The medium variation of all display devices that we measured in the past few years is 468: 1, and the average, with which many high -price viewing devices collide, is 876: 1. The total lighting, measuring with noble identities, not only the extent of the image brightness, but to what extent you can make and still have a viewable image. It does not matter some difference in Lumin, but there can be several hundreds of the difference between a dim, boring and one of the truly fixed organic pollutants. The color is a complex topic, but after years of testing, including dozens of “confrontation” with non -technical and non -reviewers, the exact color always wins the colorless or excessive color. The most accurate displays produce very natural vibrant colors to see.

Light output is the second most important factor, because not only the extent of the image appears on the wall, but also the size of the image you can produce. Most modern viewing devices are brighter than 10 years ago. We measure brightness in candlesticks per square meter (CD/M2) and then transfer to the ability brigade for easy comparison. It is important to note that we use the most accurate color temperature mode to make our brightness comparisons, but we will notice when a smaller position is brighter. Most of the display devices we experience range from 1000 and 2000 candles, with a much lower battery -lower battery models, and some specialized latitudes are higher. The average brightness of the displays that we measured over the past few years are 901 candles.

The accuracy of the color is the last main factor. No device can really benefit from HDR, Dolby Vision or Gamut Color WideBut some can do more than others. In general, we are satisfied with the fine colors, but adding HDR effects is a bonus. Most of the home theater shows we experience somewhat accurate. Budget models, those that give priority to brightness over everything, along with the devices from new arrivals to the area of ​​the projection device that have great inaccurate colors that lead to a very abnormal image.

Other factors, such as video processing and HDR processing, are evaluated in viewing tests. This is rarely a major factor in the performance of the show, but some models still use old chips that have problems.

The best display device will have a high contrast, high brightness and great color. It is difficult to do at the same time, but as long as the balance works and looks better than its competitors at a similar price, it is a winner.
