The 55" category remains the most popular choice even though larger TVs 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.
Note: Prices and availability fluctuate a lot at the beginning of the year as last year's models are gradually replaced by newer ones.
The best 55 inch TV we've tested is the LG OLED55B8. Just like the equally performing, but more expensive, models LG C8 and LG E8, the B8 has an excellent picture quality. It can display perfect, uniform blacks due to the self-emissive OLED technology that allows it to turn off each pixel individually. Thus, when viewed in a dark room, the picture looks outstanding full of rich and saturated colors thanks to the TVs wide color gamut and good brightness levels. It is also suitable for large rooms as it has good viewing angles, can fight glare and can handle reflections remarkably. The B8 like most OLEDs has an almost instantaneous response time which makes moving objects look crisp with very little motion blur.
However, like all OLED TVs, the B8 run the risk of temporary image retention or even permanent burn-in when displaying static content over prolonged periods. Under normal varied usage, though, we don't expect this to happen.
Overall, the LG OLED55B8 will perform well at any usage you throw at it.
If you do not want to be concerned about the risk of burn-in of the LG B8, then get the Samsung QN55Q8FN. Blacks are deep on the Samsung, but not perfect as on the LG OLED and unfortunately, the viewing angles are bad. On the upside, the Samsung Q8FN can get very bright, which is great if you have a bright room. It has very low input lag and supports auto low latency mode and the FreeSync variable refresh rate, which are great features if you are a gamer. Overall, it is a great TV and will please you in a variety of uses.
The best 55 inch TV in the mid-range category is the Sony XBR55X900F. You will not 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, and it will have no issues with glare.
The X900F 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, the Sony X900F will keep happy most of its future owners as it will deliver a great performance in most usages.
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 does not have the brightness levels or the great reflection handling found on the Sony X900F. 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 is more responsive than the Sony due to its lower input lag which is great if you are 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 are a soap opera effect fan, you will enjoy the motion interpolation feature.
If you are looking for a 55 inch 4k TV to use for gaming either on a PC or on a console, then get the Samsung UN55NU8000. You will not have the dark scene performance of the Sony XBR55X900F, but the Samsung NU8000 is a TV with good picture quality and a very low input lag. It has some advanced gaming features, including automatic low latency mode which detects when a game is being played and adjusts the settings so that you get the lowest possible input lag. The NU8000, just like the rest of the higher-end Samsungs, also supports for the Freesync technology, which offers a tear-free gaming experience when connected to a PC with an AMD graphics card, or an Xbox One S or X.
If the Sony X900F is too expensive, the best 55 inch TV we've tested in the budget category is the TCL 6 Series 55R617. It is also known as the 55R613 or 55R615 depending on where you buy it from. It does not have the good gray uniformity of the Sony nor can it handle reflections as good, and motion isn't as fluid due to the slower response time.
On the upside, the R617 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 is also great for HDR, as it has an excellent brightness and 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 and this is great for gamers.
Overall, the TCL 6 Series is the best 55 inch TV for the money and it offers a very good performance for most uses.
If you find the TCL R617 expensive and want a cheaper alternative, then get the TCL S series 55S405/S425. You will not get the more advanced features like local dimming or motion interpolation and the TV cannot get as bright as the TCL R617. Instead, the S425 (which is the same as the S405 with just some cosmetic improvements) is an entry-level 4k TV with the same excellent smart platform as the R617. It has a decent picture quality, and although it supports HDR there is little benefit in using it in this mode. It has an excellent low input lag that will please gamers or those who plan to use it as a PC monitor. If you are having a hard time finding it and still want a cheaper alternative to the TCL 55R617, get the TCL 55S517.
