TCL’s 65R648 delivers picture and sound quality that’s on par with or better than Samsung’s QN800—for a lot less money.

The 8K version of the TCL 6-Series has nearly everything we’d want specs-wise: 8K resolution, Mini LED backlights and a quantum dot filter for better color at the lowest price for any 8K TV. Its audio performance is far from perfect and only two ports have 4K/120Hz support for PS5 and Xbox Series X, but for the price there’s no TV out there with higher specs.

TCL's 6-Series of 8K TVs offer an excellent picture with impressive contrast and wide colors for a more affordable price than we've seen on other 8K models, though there still isn't any content to really take advantage of it.

If you're a sucker for a pretty face, you're going to like the 8K picture of the TCL 6-Series 8K. If you want to be ahead of the resolution revolution, this is a relatively affordable way to do it.

The TCL R648 is an outstanding TV and very deserving of flagship status among TCL’s product lineup. Its high brightness, solid black levels, very good out-of-box color performance, smooth motion, and excellent gaming chops make it one of the best TVs you can buy this year. The 8K resolution? That’s a bonus. Like most TV manufacturers, TCL is reserving its best TV performance for its 8K TV lineup, making the question of whether 8K really matters, moot.

It's great for watching SDR and HDR movies in a dark room because it displays deep blacks and has a decent local dimming feature, but it crushes blacks too much. It's great for watching shows or sports because it has excellent peak brightness and reflection handling, but it has narrow viewing angles. Gamers should also appreciate the low input lag, quick response time, HDMI 2.1 inputs, and variable refresh rate support for an excellent gaming experience.

The TCL Roku TV 6-Series 8K (R648) is a next-generation set at this generation’s prices, but it’s not a compelling buy while 4K reigns supreme.
