Almost every new TV that has been released this year has a 4k resolution. Unless there is a specific reason that you are 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.
We've tested 68 4k TVs in the last two years and below are our recommendations for the best ones you can buy in 2018.
The best 4k TV that we have reviewed so far is the LG B8. It has the same excellent picture quality as the more expensive LG C8. The LG B8 is an OLED TV that can display perfect blacks due to its infinite contrast ratio, and excellent black uniformity. It has excellent wide viewing angles and instantaneous response time that leaves almost no blur trail in fast action scenes. This, however, can introduce some stutter that may bother some people. The input lag is low, and gamers and PC users will appreciate the responsiveness of the TV.
Overall, it is a great TV that will keep almost anyone happy.
If the possibility of burn-in with our top-pick, the LG B8, is a concern for you, the Vizio P Series Quantum is the best LED 4k TV. The P Series Quantum has an excellent contrast ratio and a very good local dimming feature that delivers excellent dark room performance.
Unfortunately, the P Series Quantum doesn't display gradients very well. It doesn't have the wide viewing angles of the LG B8 and has a slower response time, but it is much brighter and is better suited for a bright room. It is currently very difficult to find and it is unknown if/when this will change.
If the LG B8 is too expensive for you, the Sony X900F is the best mid-range 4k TV that we have reviewed. The X900F is a versatile 4k TV that delivers great picture quality, with deep blacks, a wide color gamut, and excellent gradient handling. The response time is nearly as fast as the OLEDs, and motion looks crisp and smooth. It has great low input lag for gaming.
Unfortunately, it doesn't deliver the wide viewing angles found on the OLED LG B8, and it has worse uniformity. It is a lot brighter than the B8 but has slightly worse reflection handling.
Overall, it is a great mid-range 4k UHD TV that should please most people.
If the Sony X900F is outside of your budget, but you still want a good mid-range 4k TV, the Vizio P Series 2018 is a cheaper alternative. The P Series 2018 has a more advanced local dimming feature and a more versatile black frame insertion feature. Unfortunately, it has slightly worse input lag. Overall, it delivers similar picture quality but is not as bright.
If you find the Sony's input lag too high and are looking for a mid-range TV with better gaming characteristics than the X900F, then get the Samsung NU8000 UHD 4k TV. Its local dimming feature is not as good as the Sony's X900F and the response time is slightly slower and leaves a longer trail blur. However, the NU8000 incorporates better gaming features such as support for FreeSync Variable Refresh Rate that prevents tearing in graphics demanding games. It has a lower input lag and it automatically enables game mode when it detects a game being played on an Xbox One or PS4, ensuring you enjoy the lowest possible input lag.
If the Sony X900F is outside of your budget, the best budget 4k UHD TV we've tested is the TCL R617. The TCL 6-Series is the successor to the extremely popular TCL P607 and is also known as the R613 or R615, depending on where you buy it. It has mediocre gray uniformity that could be disappointing to sports fans.
On the upside, the 6 Series delivers very good picture quality and is just as bright as the X900F. The smart features aren't as advanced as those found on the more expensive TVs, but they are good enough for most people.
Overall, it is a very good 4k TV available at a budget price.
If you find the TCL 6-Series R617 expensive and want a cheaper alternative in the budget category, then get the TCL S405. It still delivers decent picture quality but lacks some of the more advanced features found on the R617, like local dimming and motion interpolation. If you just want a decent 4k TV and don't care about things like HDR, then the TCL 4 Series is a great choice.
Our recommendations above are what we think are currently the best 4k TVs to buy 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 that have UHD screen. 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.
