PC monitors and TVs are close relatives. Usually, they differ in design, 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.
The best TV for computer monitor use with a 43-inch screen is the Sony XBR43X800H. It's a decent overall TV with great performance as a PC monitor, and it won't cost you a fortune. Note that the 43 inch model has a more narrow stand compared to the 55 inch model we reviewed, but there's still enough space to put stuff in front of it.
It has an IPS panel with really wide viewing angles, ideal for sharing your screen with others or if you sit close to the screen. If you use it in a bright room, it gets bright enough to combat glare, and it has decent reflection handling. It displays chroma 4:4:4 on either 'Game' or 'Graphics' picture modes, and the input lag is extremely low. Fast-moving content looks smooth as it has a good response time, but even though it has a black frame insertion to clear up motion blur, it only flickers at 120Hz, which could create some duplication in motion.
Unfortunately, it has a low contrast ratio, so it's not ideal to use in a dark room. The 43 inch model is edge-lit, so we expect it to have an even lower contrast ratio than the bigger models as the backlight is direct LED. However, this TV has excellent color accuracy, so you won't need to get it calibrated if you don't want to. Overall, this is the best TV monitor we've tested available in a small size.
The best TV to use as a monitor with a large screen that we've tested is the Samsung QN65Q80TAFXZC. With a 65 inch screen, there's space to have multiple windows opened side-by-side, great for even the most extreme multitaskers. It delivers stunning picture quality with its VA panel, producing deep blacks and saturated colors. It has exceptional reflection handling and gets bright enough to overcome glare in any lighting condition. Viewing angles are decent due to Samsung's 'Ultra Viewing Angle' layer, so images remain accurate at the sides if you sit up close.
This TV has exceptionally low input lag, and, combined with its 120Hz refresh rate, it provides an incredibly responsive desktop and gaming experience. It supports most common resolutions like 1080p and 1440p, and it can display proper chroma 4:4:4 for optimal text clarity. Its response time is excellent, and it has a Black Frame Insertion feature to further reduce motion blur. It supports FreeSync to minimize screen tearing when gaming, but sadly, it isn't compatible with NVIDIA's G-SYNC.
Out-of-the-box, this TV has excellent color accuracy, so you shouldn't have to calibrate it to get the best viewing experience. There's some vignetting at the corners and some dirty screen effect on our unit; however, your experience may differ, as uniformity issues can vary between units. Also, this TV has a BGR subpixel structure, which doesn't always play well with Windows ClearType. Nevertheless, it's an excellent choice to use as a PC monitor, especially for those big meeting rooms.
If you use your TV in a well-lit room and you want a brighter TV, then take a look at the Hisense 65H9G. It's very similar to the Samsung Q80/Q80T QLED, as it also sports a VA panel that delivers fantastic picture quality. It overcomes glare easily and handles reflections well, and gets more than bright enough to make highlights pop in HDR content. Unfortunately, it has sub-par viewing angles, so images look washed out if you're not seated directly in front of the TV or if you sit too close. Additionally, its out-of-the-box color accuracy is only mediocre, and it doesn't support variable refresh rate to reduce screen tearing. On the upside, it has a higher contrast ratio and better black uniformity to provide a superior dark room viewing experience.
Overall, go with the Samsung if you need wider viewing angles and FreeSync support. However, if you need a TV that gets brighter and don't mind a few compromises, then go with the Hisense.
The best TV for monitor use in the budget category is the Hisense 55H8G. It's a very good overall TV and even though it doesn't have wide viewing angles, it's still a great choice to use as a PC monitor. It's available in a good range of bigger sizes, so you can get the one that suits your needs.
The picture quality is almost as good as some higher-end, more expensive TVs. It looks great in dark rooms because it displays deep blacks and it has a full-array local dimming feature. It performs as well in bright rooms thanks to its great peak brightness and decent reflection handling. Like the other TVs in this recommendation, it supports chroma 4:4:4 at 1080p and 4k resolutions while it's in 'Game' mode. The input lag is also really low and even though it has a 60Hz refresh rate, the response time is good, so motion looks smooth. The TV has a nice style and it's fairly well-built.
Sadly, the image degrades quickly when viewing at an angle, so it's best to sit directly in front of it. It also has just okay color accuracy if you don't calibrate it, but on the upside, it upscales lower-resolution content without any problems. All in all, if you're on a budget, most people should be happy with this TV.
If you find the Hisense H8G too big, then check out the LG 43UN7300PUF. Its 43 inch IPS panel has wider viewing angles, allowing you to sit closer to the screen without losing too much image accuracy on the sides. It has excellent reflection handling but doesn't get very bright, so it's a better fit for a moderately-lit room. It has low input lag, decent response time, and it can display chroma 4:4:4 properly. Unfortunately, it isn't as well-suited for dark settings due to its low contrast ratio, which makes blacks look grayish. Also, even though it supports HDR, it can't display a wide color gamut and lacks local dimming.
For most people, the Hisense is a better choice, as it delivers better picture quality and can get much brighter to combat glare. However, if you don't have the room for such a big TV or you just prefer something smaller, the LG is a good alternative.

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 TV reviews. 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.
