OLED TVs have the best picture quality currently available. If you are watching TV in a dark room, OLEDs can display perfect blacks, which enhance picture quality. They cannot get as bright as LED TVs and have a risk of image retention or burn-in, although we expect most people not to be affected by this.
Note: Prices and availability fluctuate a lot at the end of the year and especially after Black Friday.
The best OLED TV we've tested so far is the Sony A9F. It has an excellent picture quality with perfectly deep blacks that look great in a dark room. It has very good wide viewing angles, and you can easily place it in a large room with a wide seating arrangement. The Sony A9F has excellent HDR performance. It has an excellent color gamut and very good color volume so it can display scenes with rich, saturated colors and highlights that pop. Motion handling is excellent due to an almost instantaneous response time that leaves only as small blur trail. It also has a low input lag that makes it a good choice for gamers. Finally, the Android 8.0 smart platform is very fast.
Unfortunately, the Sony A9F has the risk of temporary image retention and permanent burn-in if you project static images for a prolonged period of time, just like all OLEDs. However, we expect most people not to be affected by this.
Most OLED TVs of the same year have a picture quality in the same ballpark, even across brands. While it is pricier, the Sony A9F has a small edge for people that watch HDR movies and that want color accuracy. It has slightly better gradient handling, better color volume, and a less aggressive automatic brightness limiter (ABL) than the other OLED TVs like the LG C8.
If you want an OLED TV with excellent performance that is less expensive than the Sony A9F, then get the Sony A8F. It does not have the very low input lag or the excellent color volume coverage that you will find in the A9F. On the upside, the A8F has an excellent performance for a variety of different usages, due to the excellent picture quality with perfect blacks, and the impressive motion handling.
If you are looking for lower input lag than the Sony A9F provides, the best gaming OLED TV is the LG C8. It does not have the great color volume or the perfect 24p judder removal of the Sony A9F. On the upside, the LG C8 has an excellent picture quality with perfect blacks and very good viewing angles. The LG C8 has excellent HDR performance and excellent motion handling with an almost instantaneous response time that displays fast-moving content with only a small blur trail. It has a low input lag, allowing it to react quickly to your actions and this is great news for most gamers or those who will use it as a PC monitor.
Just like all OLEDs, the LG C8 has the risk of temporary image retention and permanent burn-in. This happens only if you display static images for a prolonged period of time, and we expect most people not to be affected by this.
Overall, the LG C8 is an excellent OLED TV that will perform very well in most usages and especially in gaming.
If you find the LG C8 too expensive and still want an excellent OLED for gaming, then get the LG B8. You will not get the new A9 processor (as the B8 still has last years' Alpha 7) and the wider and sturdier stand of the C8. On the upside, the two TVs have the same great picture quality and speed differences between them are marginal. They are both excellent OLED TVs with minor differences that can be attributed to panel variance.
On the upside, the E8 has a remarkable performance in almost any usage. It has excellent picture quality with great motion handling and a unique premium design. It has a dedicated soundbar that performs well and will cover the needs of most people.
Currently, only LG and Sony sell OLED TVs in the US, and they all have similar picture quality. Some manufacturers like Philips and Panasonic have produced some OLED TVs that use LG panels, but these aren't sold in the US.
Our recommendations above are what we think are currently the best OLED TVs to buy for most people. 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 OLED TVs. 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.
