The 55" category remains the most popular choice for TVs, even though larger options are slowly but steadily gaining market share. 2018 was a good year for TVs, as the models we have tested were better than their last year's counterparts. New technologies are maturing and are becoming available to more mainstream models.
The LG B8 is the best 55 inch TV we've tested so far. This TV delivers impressive picture quality, thanks to the OLED panel's ability to turn off or dim individual pixels, which results in perfect black uniformity and a nearly-infinite contrast ratio. This TV also has outstanding wide viewing angles and amazing motion handling, thanks to the nearly-instantaneous response time.
OLED TVs aren't perfect, though, and this one has a risk of temporary image retention or even permanent burn-in. This is most likely to occur if you watch a lot of static content, but with mixed usage, we don't expect this to be an issue for most people. The brightness also changes depending on the content displayed, which can be distracting in some cases.
Overall, this TV delivers outstanding picture quality, and it has excellent motion handling and amazing low input lag. This makes it a great choice for almost anyone.
If the possibility of burn-in with the LG B8 OLED concerns you, the Samsung Q80/Q80R is the best LED alternative. This TV has outstanding motion handling, great picture quality, and incredible low input lag. It has great smart features and great additional gaming features, including support for AMD's FreeSync variable refresh rate technology. It isn't perfect, though, as it has worse gray uniformity than the LG, and although it looks great in a dark room, it can't produce the outstanding blacks of the OLED panel.
The best 55 inch smart TV in the mid-range category is the Sony X900F. You won't get the wide viewing angles of the OLEDs, but you will get a TV with excellent brightness that you can easily place in a bright room. It will have no issues with glare.
This TV has a great picture quality and can perform very well in a dark room thanks to the deep blacks produced by the high native contrast ratio and full array local dimming support. HDR content is great, full of rich colors and highlights that pop. It has a very fast response time with very little blur and a low input lag to please gamers.
Overall, this TV will keep most of its future owners happy, as it will deliver a great performance.
If you find that the input lag on the Sony X900F is too high, then check out the Vizio P55-F1 P Series 2018. It doesn't have the brightness levels or the great reflection handling found on the Sony. If these features are not a priority and you would prefer to save some cash, the Vizio will keep you happy as it will perform very well overall. It's more responsive than the Sony due to its lower input lag, which is great if you're a gamer or often use the TV as a PC monitor. It has a fast response time and can handle fast content well. Finally, if you're a soap opera effect fan, you'll enjoy the motion interpolation feature.
If you want a great gaming 55 inch 4k TV to use with a PC or with a console, then check out the Samsung RU8000. It doesn't have the same deep blacks in a dark room or the same great HDR performance as the Sony X900F, but it's a TV with good picture quality and an extremely low input lag. It has some great gaming features, including auto low latency mode and low input lag with motion interpolation, and support for FreeSync VRR for nearly tear-free gaming. Overall, it's a very good TV that excels in gaming.
If the Sony X900F is too expensive, the best budget 55 inch TV we've tested is the TCL 6 Series R617. It's also known as the 55R613 or 55R615 depending on where you buy it from. It doesn't have the good gray uniformity of the Sony nor can it handle reflections as well, and motion isn't as fluid due to the slower response time.
On the upside, this TV has a very good picture quality, with deep blacks in a dark room due to the full-array local dimming and the high native contrast ratio. It's also great for HDR, as it has excellent brightness and a wide color gamut. It has some very good motion handling features like fast response time, an excellent black frame insertion feature, and a motion interpolation feature. The input lag is very low, which is great for gamers.
Overall, this is the best 55 inch TV for the money and it offers very good performance for most uses.
If you want to spend less than the cost of the TCL R617 for a budget 55" TV, check out the TCL 4 Series S425 2019. It doesn't have more advanced features like local dimming or motion interpolation, nor can it get as bright as the R617. On the upside, it costs less and runs the same excellent smart platform as the other TCL. Unfortunately, it can't deliver a good HDR performance and there is little benefit in using it in this mode. Gamers will appreciate the excellent low input lag, which is also great for those who will use it as a PC monitor. Overall, it's decent and is best as a secondary TV.
