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, the LG B9 is an excellent TV with excellent performance no matter the use.
If the burn-in risk of the LG B9 OLED concerns you and at the same time you'd like to save some cash, then get the Vizio P Series Quantum X 2019. You won't get the wide viewing angles or the perfect blacks of the OLEDs and it's only available in larger sizes. It is, however, an excellent TV with great picture quality, that performs just as well in a dark room as in a bright room. It's one of the brightest TVs we've tested and will easily fight glare. it displays HDR content full of saturated colors and highlights that pop and has excellent motion handling. Overall, it delivers a remarkable performance in most uses.
If you want the best picture quality, get the LG; otherwise, if burn-in is a concern and you sit straight in front, the Vizio is the best LED alternative, and it'll save you some cash.
The best 4K TV for color accuracy is the Sony X950G. With just a few settings adjustments, this TV can deliver a very accurate image. It doesn't have the perfect blacks or the great wide viewing angles of the OLEDs, but it's an impressive TV with great picture quality. It displays deep blacks in a dark room thanks to the high contrast ratio and decent local dimming support. You can easily place it in a bright room as it'll handle reflections well and can get very bright to fight glare. HDR content looks excellent full of saturated colors and bright highlights, thanks to its wide color gamut. It has a very fast response time, so fast-motion looks crisp with only minimal blur and the input lag is low enough to please casual gamers, although more competitive gamers might want something better.
Unfortunately, just like most LED TVs, the image degrades when viewed from the side and isn't the best choice for a wide seating arrangement, unless you get the larger models that incorporate the 'X-Wide Angle' layer that improves viewing angles at the expense of contrast ratio.
Overall, this is an impressive TV with an impressive performance in most uses.
If you find that the viewing angles on the Sony X950G aren't suitable for your large room and 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 dark room performance of the Sony, 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 for wide viewing angles and don't mind compromising on dark room performance, the LG SM9000 is a great choice; otherwise, the Sony X950G 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. You won't get the out-of-the-box color accuracy of the Sony, 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 X950G is a better choice; if gaming is your passion, then the Samsung Q70/Q70R 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 is 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 for 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.
