With the development of display technology, the price of hd LCD TV is also lower and lower, the function is also more and more rich, will someone say, can you use the TV as a display device?
Generally, high-definition LCD TV can be used as a display for the following reasons:
First, liquid crystal displays and liquid crystal screen display imaging principle of the basic working principle and basic phase imaging mode, the same part of the function of coincidence degree is high, and both with images for output purposes, the structure of the internal basic same, but compared with the computer monitors, LCD TV price more prominent, and the dimensions than displays rich, with price, display and television in the specifications and performance on the TV.
Second, the current LCD TV data interface is generally equipped with VGA and HDMI, which can be directly connected to the computer ah, so, should be able to do the display.
Again, now the appearance of a lot of monitors and TV are similar, advocate thin and thin, without a frame, curved, it seems that there is no difference, so, used as a monitor is not a problem.
Why can't high definition liquid crystal TV do monitor
However, in fact, hd LCD TV is not suitable for the display, for the following reasons:
1. The TV display screen is too bright as a monitor
Compared with the monitor, the brightness of the TV is too high, the brightness of current mainstream monitor is in 200-300cd/m2, can achieve the best brightness range of 120-150cd/m2 through adjusting the brightness, and the TV general brightness can reach 400-700cd/m2, when close range is used very harm the eye, say without a word is "bright blind"!And at present the TV in the home is above 40 inches, with such a large TV to work in close proximity, games, the effect can be imagined.So, even for 32 inches, 40 inches of television screen modification as a monitor, are blinding.
2, when the TV screen display, picture fuzzy, unstable, color phenomenon
If the host is connected with TV, the display picture will be very fuzzy, and the picture will be unstable. The phenomenon of color bias and the detail loss of close viewing picture are serious, which indicates that the gray scale output of TV has a loss. Taking 256 gray scale as an example, the TV will display 16-236 parts, and the rest of the gray scale is lost.
3, on the big screen TV, even if 4K particle full
Now 4K TV has been very rich, but under the same resolution, the size of the TV screen is often much larger than the computer screen, the display screen has a large dot distance, the naked eye can see the obvious particle sense, the picture is very rough.
4. Not professional enough
As a display device, the biggest difference between a monitor and a TV is professionalism.For the display, the pursuit of rich color and accurate restoration, consumers hope that the display can achieve wysiwyg, general TV screen color gorgeous.
If you have tried to mainframe computers to the liquid crystal TV, will found the output on the LCD TV picture too gorgeous, some models of partial color will be very serious, and severe slants color is rooted in gamma adjustment, display the default gamma value is 2.2, because of the different application scenarios, gamma value of the TV at about 2.4, so the use of television screens in screen video is ok, but other things are a bit overwhelmed.
5. Refresh frequency is different
Compared with the monitor, the refresh rate of the TV is generally 30-60hz, which cannot reach the 144Hz of the current esports display, let alone the 165Hz of some high-end esports.Using the TV screen to play the game screen will have a serious drag, compared with the screen display, the TV connected to the mainframe display effect is not up to the requirements.
