Can I use a TV as a computer monitor?


Some game players may wonder can I just use a TV as a computer monitor? Since we can get a larger screen ultra clear LCD TV at the same price as a monitor.


TV sets have a long history of being used as monitors, from the red and white of the last century to the PS5 and XBOX, all connected to the TV for play. But if you want to play a PC game on a $300 LCD TV, you probably won't get a particularly good gaming experience.


Let's start by comparing TVS and monitors at the same price.

The $300 TV not only has a large size of 55 inches or more but also has 4K ultra high definition resolution and HDR support. But TVS at this price point are at the lower end of the spectrum, followed by thousands of TVS with larger sizes, better display technology and better resolution.

$300 price segment of the display has already had an obvious division of labor, mainly divided into professional office display for work and game players necessary esports display, the former has a better resolution, more accurate color performance, and the latter has a higher refresh rate, lower response delay and suitable for different games display function.

It seems that a TV is better than a monitor, because the TV has a larger screen and 4k HDR, and monitors at the same level need more costs. Is that true? What's the difference between tv and a monitor?


1. color accuracy and color difference

We need to make it clear that TV sets are made to display images of film and television variety shows, so the mainstream color gamut standard of TV sets is REC.709 standard or DCI-P3 standard, which are specially customized for film and television images. In addition, TVS add some filters to the display for users' perception, making the picture more colorful. We often find in our evaluations that different TVS display the same image will have completely different picture effects.


You might think bright colors are better, but this can be a nightmare for art and film workers. For the staff and the game players may not need a bright picture, more accurate picture color display is very necessary. The main color standards for displays are sRGB and Adobe's Obergb, which are better at displaying original colors.

Brighter picture colors are a nice plus on TV, but they can backfire on the monitor. The monitor that can output the image processed by the graphics card and restore the true color of the picture is much better for both games and work.


2. the screen can not only focus on the resolution

It is true that the higher the resolution, the clearer the screen, but in fact, the visual perception of the screen is closely related to the resolution and screen size.

Resolution refers to the number of pixels on the entire screen. If a 55-inch screen and a 27-inch screen have the same number of pixels on a 2K screen, the difference in pixel density will appear. This leads us to PPI, which is the number of pixels per inch on a screen. The PPI of a 55-inch 4K TV is about 84, and the PPI of a 27-inch 2K monitor is 89. At the same distance, the viewing experience of a 55-inch 4K TV is basically the same as that of a 27-inch 2K monitor.

Obviously, in the professional image work, a $300 4K small size monitor is certainly more delicate than 4K large screen TV picture.


3. Latency vs. refresh rate

The fluctuating "pings" in the upper left corner of an online game player's game count for each round of play, and the physical delay in the TV picture can crash you.

Video playback on a normal TV doesn't refresh at a high rate, which affects the gaming experience.

The aim and shooting feel of online games and the keyframes of stand-alone action games all require the precision of operation. Display delay and picture dragging are fatal to game players. There are many professional esports monitors with a refresh rate above 144Hz and delay as low as 1ms at the price of $300. Although only 2K resolution, the other two are far more important than picture quality.
