PC monitors and TVs are close relatives. Usually, they differ in design and image processing capabilities and connectivity. TVs usually have more advanced image processing capabilities than monitors and come equipped with TV tuners and integrated speakers, whereas monitors usually have DisplayPort connections that TVs still lack.
Most TVs offer a PC Mode option, which removes the extra image processing and ensures the lowest possible input lag. The most important things to take into consideration when choosing a TV for PC monitor usage are the TV's supported resolutions, the ability to display chroma 4:4:4, and the viewing angles that can cause uniformity issues when sitting close to the screen. You'll want to get an LED TV to use as a PC monitor since OLED TVs have the risk of permanent burn-in.
We've tested more than 70 TVs in the last two years and here are our recommendations for the best TVs to use as a PC monitor in 2020. See also our recommendations for the best TVs, the best LED TVs, and the best HDR TVs.
The best TV for use as a PC monitor is the LG 43UM7300. It's a 4k TV with decent build quality and a reasonably accurate color reproduction out of the box. Text looks sharp, as it can display proper chroma 4:4:4, and the IPS panel's wide viewing angles are great for those who like to sit close to the screen. It may not be the best choice for use in dark rooms due to the mediocre contrast ratio, but it has excellent reflection handling and can get bright enough to combat glare in a well-lit room.
This TV's fast response time and low input lag provide a responsive desktop experience; however, it doesn't support FreeSync variable refresh rate for those who want to game on this TV. Although it supports HDR, it can't get bright enough to bring out highlights in HDR content, not to mention that it doesn't support a wide color gamut. Unfortunately, the backlight isn't flicker-free, and its 120Hz flicker can be distracting for some. On the bright side, IPS panels are immune from burn-in, so you shouldn't have any issues with the user interface being always in the same spot.
Overall, if you want a large TV to use as a monitor, this one is a great choice.
The best large TV to use as a PC monitor is the Samsung Q80/Q80R QLED. It's a fantastic TV to use as a PC monitor with outstanding picture quality and it properly displays 4:4:4 chroma on 1080p and 4k resolutions, so you'll be able to read your screen's text with ease. It has an incredibly low input lag, so it responds to your commands almost instantly.
This TV can get extremely bright and it does an amazing job at handling reflections, so you can place it in any bright office and not worry about light reflections. VA panel TVs like this one are known to have poor viewing angles, but Samsung added an 'Ultra Viewing Angle' to improve the image accuracy when viewed at the side, so it has decent viewing angles if you need to put this TV in a meeting room. Unfortunately, the gray uniformity could be better and it gets darker on the sides, but on the upside, it supports a wide color gamut, displaying a wide range of colors.
Overall, this is an amazing TV with impressive picture quality, making it the best large TV to use as a PC monitor.
If your TV room has a lot of ambient light and you find that you need a TV that can get even brighter than the Samsung Q80/Q80R QLED, then get the Vizio P Series Quantum X 2019. You won't get the Samsung's wide viewing angles, and the Vizio doesn't have support for FreeSync or other gaming goodies. It is, however, one of the brightest TVs we've ever tested, and as long as you sit straight in front the picture quality is impressive. It's very responsive thanks to the low input lag, and displays crisp text when used as a TV monitor thanks to its ability to display chroma 4:4:4 properly in the most common resolutions.
If you want the absolute best TV for use as a PC monitor, get the Samsung, but for a brighter room while sitting straight in front, the Vizio is a better choice.
If you think that the Samsung Q80/Q80R QLED's viewing angles cause uniformity issues, then check out the LG 55SM9000. It can't deliver the same dark room performance as the Samsung, and it lacks the FreeSync support for tear-free gaming. On the upside, the input lag is very low, making the TV very responsive to your actions, and it supports chroma 4:4:4 and can display very crisp text when used as a PC monitor. Thanks to the IPS panel, it has wide viewing angles and there aren't any uniformity issues at the edges you watch from up close.
Overall, if you want the best large TV for use as a PC monitor, get the Samsung, but if viewing angles are very important, the IPS LG is a better choice.
The Hisense 55H9F is the best budget TV for use as a PC monitor. It has a remarkably low input lag and ensures a responsive PC using experience. It also supports the most common resolutions, except the ones @ 120Hz, and can display proper chroma 4:4:4 in the ones it supports, displaying sharp text. It has great picture quality that looks great in both a dark and bright room.
Unfortunately, the image deteriorates when viewed from the side, but this shouldn't be an issue if you're sitting directly in front of the TV at a comfortable viewing distance. If you're too close, however, the edges of the screen appear non-uniform.
Overall, though, this is a great TV that you can easily use as a PC monitor and comes at a budget price.
If you're looking for a cheaper and smaller alternative, the TCL 4 Series 2019 43S425 is a good choice. It doesn't deliver the same great picture quality the Hisense H9F does, but it's available in 43, 49, and 50 inch models if you don't have enough space for the 55 inch Hisense. The TCL has an incredibly low input lag, great for productivity and web browsing, and it has an excellent response time, so motion looks clear. Unfortunately, the viewing angles are poor, so it's not suggested to place in a meeting room or use it to share with your co-workers, but it has a fantastic contrast ratio and decent black uniformity if you need to use it in the dark.
If you want the best budget TV to use as a computer monitor, you can't go wrong with the Hisense, but if you need something smaller and cheaper, then look into the TCL.
