Picture quality is one of the primary characteristics that make a TV stand out. Motion, sound, inputs, and smart features are also important, but if the picture isn't good, everything else becomes secondary. There are different TV technologies you can find in the market, each with its advantages and disadvantages. One of the dominant technologies is LED LCD TVs. As with every technology, there are quite a few variations, some of which are discussed here. One of those variations is the quantum dot technology, which uses a quantum dot color filter that results in a wider color gamut. Since 2017, Samsung rebranded its 'SUHD' TVs as 'QLED'. Although QLED has been mostly associated with Samsung, other manufacturers like Vizio produce quantum dot technology TVs.
We've tested 69 TVs, and below are our recommendations for the best quantum dot technology TVs you can buy in 2019.
The best QLED TV we've tested so far is the Samsung Q90/Q90R QLED. This is a remarkable TV with impressive picture quality that delivers an excellent performance in any use. It has a high contrast ratio and very good local dimming; these allow the TV to deliver deep blacks that greatly improve the picture quality in a dark room. It's a very bright TV that you can easily place in a bright room, where it'll fight glare and handle reflections well. It has a wide color gamut, and thanks to its high HDR peak brightness can display vivid color and highlights that pop in HDR content.
Even though this TV has a VA panel, the image remains accurate when viewed from the side thanks to the 'Ultra Viewing Angle' technology. Fast-moving content is crisp due to the fast response time, which will please sports fans. This TV also has something for gamers. The input lag is very low, and among other gaming features, this TV supports FreeSync for nearly tear-free gaming. Unfortunately, just like all TVs, it's not without faults and some enthusiasts might find the vignetting that this TV has disturbing.
Overall, this is an excellent TV for everyone.
If the Samsung Q90/Q90R QLED is above your budget but you still want one of the best QLED TVs that performs just as well, then get the Samsung Q80/Q80R QLED. It has very similar performance to the other Samsung but lacks the One Connect box where all external inputs ports are. This can be both an advantage or a disadvantage depending on your TV room layout. Performance-wise, this is an excellent TV in any use. It has Samsung's 'Ultra Viewing Angle' layer, which enhances viewing angles at the expense of contrast ratio.
If you want the absolute best QLED TV out there, get the Q90R. If, however, your budget's a bit tighter and you don't mind not having the One Connect box, the Q80R is a similar performing TV that won't let you down.
If you want to future-proof your purchase, then check out the Samsung Q900/Q900R 8k QLED. It's an excellent 8k QLED TV with great picture quality. Regarding 8k content, the TV's supported resolutions, and commercially available devices that can take advantage of the TV's capabilities, see our full review.
This is a TV that can get very bright and can handle reflections well, so you can easily place it in a bright room. It has a wide color gamut and can display vivid HDR images with highlights that pop thanks to its HDR peak brightness. The TV has the 'Ultra Viewing Angle' layer, which maintains an accurate image when viewed from the side. However, this happens at the expense of lower contrast, and although it has a very good local dimming support, the dark room performance is great but not excellent like on the Samsung Q80R or the Samsung Q90R. Motion on this TV is excellent and gamers will appreciate the very low input lag and the full set of gaming features that all premium Samsungs have had since 2018.
Overall, this is an excellent TV with remarkable performance for most uses.
If you're looking for the best value QLED TV for the money, then get the Vizio P Series Quantum X 2019. It doesn't have the new viewing angle enhancing technology found on the higher-end Samsung TVs, so the viewing angles aren't as good. However, this is an excellent TV with great overall picture quality. It's one of the brightest TVs we've tested and you can easily place it in a very bright room as glare isn't an issue. It has a wide color gamut and delivers HDR content with vivid color and highlights that pop. The Vizio also performs exceptionally when in a dark room, thanks to the deep blacks due to the high native contrast ratio and local dimming support. It has good motion handling and a very low input lag that will please even the most competitive gamers.
It isn't perfect, though, as the image degrades at an angle and the backlight flickers at 120Hz; this causes duplications that can bother some people. Finally, gamers might find the lack of support for more advanced gaming features like AMD's FreeSync variable refresh rate, common on Samsung higher-end models, limiting.
Overall, this TV is a great value for the money.
If you're looking for a TV with quantum dot technology but aren't willing to break the bank over it, then check out the Vizio M Series Quantum 2019, the best QLED TV in the budget category that we've tested so far. It doesn't have the gaming goodies or the 'Ultra Viewing Angle' layer found on the high-end Samsungs like the Samsung Q80R and the Samsung Q90R, and it can't get as bright as the Vizio P Series Quantum X 2019. On the upside, this is an impressive TV with very good picture quality.
This TV delivers deep, uniform blacks, and very good HDR performance thanks to its outstanding color gamut and decent HDR peak brightness. It has an excellent response time that delivers very crisp motion and good overall motion handling despite the lack of a motion interpolation feature. It also has a very low input lag that'll please gamers, but unfortunately, the image loses accuracy when viewed from the side, just like most VA panels.
Overall, this is a very good TV that will keep those who buy it happy.
Our recommendations above are what we think are currently the best quantum dot technology TVs to buy for most people with different tastes. We factor in the price (a cheaper TV wins over a pricier one if the difference isn't worth it), 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 with their mixed-usage performance. 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.
11/10/2019: Minor updates to the text and verification for accuracy. The Vizio P Series Quantum X 2019 replaces the Vizio P Series Quantum 2018, which is becoming harder to find.
