Almost every new TV that has been released this year has a 4k resolution. Unless there's a specific reason that you're looking for a 1080p TV, you should be able to cover your needs with one of the 4k models that are available on the market.
The best 4k TV we've tested so far is the LG B9 OLED. Just like all OLEDs, it delivers an excellent picture quality mainly due to its perfect blacks when in a dark room. It's slightly cheaper than its peers, the LG C9 OLED and the LG E9 OLED, which deliver similar overall performance. It's a great choice if you frequently watch TV while moving around, thanks to its wide viewing angles that maintain an accurate image when viewed from the side. It can get decently bright and has a wide color gamut, displaying vivid colors and bright highlights in HDR. Fast-moving content looks crisp with minimal blur, thanks to the almost instantaneous response time, which, however, creates stutter in movies. Thankfully, you can minimize stutter using the TV's motion interpolation feature. It has a very low input lag, great for gaming or for the times you'll use the TV as a PC monitor.
Unfortunately, just like all OLEDs, it has the risk of temporary image retention and the risk of permanent burn-in. This is more likely to occur as a result of displaying static images for prolonged periods. We don't expect this to be an issue for most people with normal, varied use.
Overall, this is an excellent TV with excellent performance no matter the use.
If you want a cheaper alternative to the LG B9 OLED that doesn't have the risk of burn-in thanks to its LED panel, then check out the Vizio P Series Quantum X 2019. You won't get the LG's perfect blacks or wide viewing angles, but this is still an excellent TV overall. This is just like its predecessor the Vizio P Series Quantum 2018, which is just as good if not slightly better but has become hard to find. This TV delivers an impressive picture quality with deep blacks in a dark room, good motion handling, and an excellent low input lag, which is great for gaming. Overall, this is an excellent TV that will cover most people's needs.
If you want a 4k LED TV that won't break the bank, then get the Vizio; otherwise, if the best picture quality on a 4k TV is non-negotiable, then the LG should be your choice.
If you care about colors being as accurate as they can be, get the Sony X950G, the best 4k TV for color accuracy. Just like its predecessor, the Sony X900F, you can obtain a remarkable color accuracy on your picture with just a few settings adjustments. You won't get the same perfect blacks as you will on an OLED TV, and the image deteriorates when viewed from the side. On the upside, this TV can get very bright and can fight the glare of any room. It can deliver HDR content with vivid, saturated colors and highlights that pop, thanks to its wide color gamut and high HDR peak brightness. Dark room performance is great thanks to the deep, uniform blacks that the high native contrast ratio, the great black uniformity, and the local dimming support deliver. This TV has a low input lag, suitable for casual gaming.
Unfortunately, the image degrades when viewed from the side, as with most VA panel TVs, unless you buy one of the larger models that incorporates the 'X-Wide Angle' layer that improves viewing angles at the expense of contrast ratio.
Overall, this is one of the best 4k TVs and certainly the one with the best out-of-the-box color accuracy.
If you find that the Sony X950G's viewing angles aren't suitable for your large room and you want a great 4k TV with an image that remains accurate when viewed at an angle, then check out the LG SM9000. You won't get the Sony's dark room performance, but on the upside, this TV displays an image that remains accurate at an angle. The LG has a good picture quality and can deliver great overall performance that's suitable for dim or brighter rooms. It has a very low input lag that makes it feel very responsive, and gamers will also like the effective BFI feature that can make the image look crisper.
Overall, if you care about wide viewing angles and don't mind compromising on dark room performance, the LG is a great choice; otherwise, the Sony is better overall.
If you want a TV with lower input lag and better gaming performance than the one found on the Sony X950G, then get the Samsung Q70/Q70R QLED. You won't get the Sony's out-of-the-box color accuracy, but this TV is equipped with gaming goodies like FreeSync Variable Refresh Rate support for nearly tear-free gaming. The input lag is remarkably low, even with motion interpolation enabled, and there is an auto low latency mode that switches you to 'Game' mode to ensure the lowest input lag once it detects you're gaming on a compatible device like the Xbox One or the PS4.
If color accuracy is important to you, the Sony is a better choice; if gaming is your passion, then the Samsung is the right TV for you.
The best budget 4k TV we've tested is the Hisense H9F. You won't get the Sony's excellent reflection handling, but on the upside, this TV offers a great picture quality with deep blacks, excellent peak brightness, and a great color gamut which helps HDR content stand out. It has an excellent motion handling and delivers crisp motion thanks to the extremely fast response time. Surprisingly, it only supports 60Hz input formats, despite the 120Hz panel.
Just like all VA panel TVs, the image loses accuracy when viewed from the side and its gray uniformity is just decent, which might worry some demanding sports fans but will be good enough for most people.
Overall, this is an impressive TV and certainly the best 4k TV for the money.
If you want an even cheaper TV than the Hisense H9F, then check out its sister, the Hisense H8F. This TV doesn't have as fast a response time as the other Hisense and motion has more blur, which might bother demanding sports fans or PC gamers. On the upside, it's cheaper and has better black uniformity, which looks great in a dark room. Overall, this is a great TV with impressive picture quality that can deliver a great movie experience.
If you care about crisp motion and picture quality, buy the H9F; otherwise, if you can compromise a bit on picture quality and motion handling to save some cash, then the H8F is a great alternative.
