What if I buy a TV and use it as a monitor?

- Jul 24, 2018-

Do you want to use 4K TV as a monitor? I am afraid many people have thought about this kind of problem. But is it really possible to use the TV as a monitor?

 

In fact, the display and the TV seem to have the same size and effect, and even the working principle is the same, but the actual use gap is not small, which is mainly caused by the difference between the display and the TV positioning. The positioning of the display is a computer screen output device, which can shoulder a variety of applications such as office, Internet, picture design, work, games and so on. The application of TV is more singular, that is, the output of video signals. Of course, the detailed is to look at cable TV, IPTV, watching movies, etc., but if you really use it, the difference between the two is quite big.

 

The brightness of the mainstream display is usually 250-300 nits, and the TV can reach 400 nits or more. The irritating effect on the eyes can be quite large under such close viewing. Of course, some people say that you can adjust the brightness. Of course, the TV can adjust the backlight intensity and brightness parameters to achieve the final brightness adjustment. However, this parameter is very difficult to adjust, the backlight is lowered to lower the color gamut, and the brightness is lowered to make the picture dark and uncomfortable. . The display generally only has brightness adjustment, and the settings and effects are much more convenient.

 

In addition, the gamma setting of the TV and the display is also different. Generally, the display defaults to 2.2 and the TV is 2.4. A good monitor can adjust the gamma, but a cheap TV generally cannot adjust the gamma. The gamma value of 2.4 in different scenes will appear to be distorted. In addition to the brightness, the grayscale output of the display is different from that of the TV. The display is generally 1-256 grayscale, and the TV is 16-236 output, which means that the TV will lose some grayscale signals.

Just now we mentioned the color gamut. The NTSC color gamut range used by TV is wider than the SRGB of the display, which means that the TV color is more expressive. But don't forget that the monitor pursues accuracy. The display can be used in addition to games and movies, including image design, printing, etc., so color accuracy is more important.

 

The pursuit of TV is the wide and bright color coverage, giving a rich, vivid visual effect. Because of this, many quantum dot TVs have ultra-high color gamut values, but their color accuracy is far less accurate than ordinary displays. So if you use TV to do design, it is estimated that the artist will rebel. (Design lines: What breaks the TV, the eyes are going to get rid of, the color is bad, and the customers are all biased)

 

Hard to say the picture, the cheap TV has a very terrible problem is the light leakage, the display currently has IPS, VA or even TN and other screens, the display at the same price usually leak control is not bad. But the cheap TV is not right. Because the TV must use a wide viewing angle panel, the cheap IPS and VA will become the hardest hit area. The light leakage in the four corners of the black screen will be very serious, even in the case of whitish, of course high-end There are far fewer such problems with TV, after all, the price is there.

 

In addition to the color of the screen, the grayscale response speed of the TV panel is usually slow. After all, the TV is used to watch TV and movies, and the monitor will use some 2ms, 5ms and 8ms panels in pursuit of the game effect, so there is a clear difference in the game effect. Especially when it comes to FPS games and racing games, TV smear will be more obvious.
