PC monitors (see our monitor reviews) 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.
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.
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 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.
If you need a large TV to make your presentations at the office but also for occasional movie nights, then the LG UM7300 might not be big enough; in that case, you should check out the Samsung QN55Q80R. This is an excellent TV that's available in larger sizes starting at 55", but comes at a higher cost. Although it has a VA panel, it has wide viewing angles thanks to the new 'Ultra Viewing Angle' technology that allows the image to remain accurate for wider angles at the expense of a slightly lower contrast ratio. However, this TV can deliver excellent dark room performance thanks to its high native contrast ratio and great local dimming support. It's also a great TV to use as PC monitor thanks to its low input lag, the fast response time, and proper support for chroma 4:4:4, which delivers clear text when used as a PC monitor.
Overall, this is an exceptional TV with a remarkable performance that'll keep its owners happy.
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 don't mind going with a smaller TV, the TCL 43S425 is a much cheaper alternative to the Hisense H9F. It's a fairly basic TV, but it performs well nonetheless. It has excellent dark room performance thanks to its outstanding contrast ratio and decent black uniformity, but it may struggle a bit if you're in a bright room due to its low peak brightness. Response time and input lag are both exceptional, providing a responsive experience, but it lacks advanced gaming features such as variable refresh rate. Unfortunately, the panel is limited to 60Hz and the backlight isn't flicker-free.
Overall, the Hisense is a significantly better TV, but for a cheaper option, the TCL will get the job done, as long as you're okay with its smaller size.
Our recommendations above are what we think are currently the best TVs to use as a PC monitor for most people in each price range. We factor in the price (a cheaper TV wins over a pricier one if the difference isn't worth it), feedback from our visitors, and availability (no TVs that are difficult to find or almost out of stock everywhere).
If you would like to do the work of choosing yourself, here is the list of all our reviews of TVs. Be careful not to get too caught up in the details. While no TV is perfect, most TVs are great enough to please almost everyone, and the differences are often not noticeable unless you really look for them.
01/21/2020: Minor text and structure changes, no change in recommendations.
