Massive TV with tons of “premium” features
This TCL 85” QLED TV is the perfect mix of price to performance for a large living area. The QLED picture is plenty bright for well lit areas with moderate amounts of direct sunlight. Assembly was relatively simple; just install the legs, plug it in, and the initial setup screen guides you through setup. The included remote is a more traditional size; some newer TV’s come with an oversimplified remote that is simply too small. This one is perfectly balanced, solid build quality, and has built in voice commands for use with the Google TV interface. The WiFi signal is great without any stuttering, though we have a mesh WiFi system with 1 gigabit internet more to thank for that. After proper setup and color calibration, the colors in scenes are really punchy with the HDR and Dolby Vision certified signal processing. While the inputs are limited to 4K@60hz, in real world use you won’t really be able to tell the difference of not having HDMI 2.1 for 4K@120hz. It has all the modern features like Dolby Atmos support, eARC, HDMI CEC, a plethora of apps available through the Google TV interface, and relatively snappy menu navigation for a “budget” TV. I own several different types of TV’s from old school LCD panels to LG’s latest OLED’s, and unless you have them side-by-side, you’d be hard pressed to notice visual clarity differences in most viewing situations, and this one looks and feels premium. Did I mention it’s HUGE? Installation was straightforward, but still a pain just given its sheer size. It weighs a LOT, and it’s awkward to lift something this large just to set onto a media console, let alone mounting to a wall. The audio quality is actually fantastic for built in speakers; it has a rear speaker in the center for low frequencies as a built in subwoofer! We will be connecting a true Atmos setup to it eventually, but the built in audio is plenty loud and punchy for most people just watching streaming shows, YouTube, or live broadcast TV. Overall I’d give this 5 stars, especially given its picture and sound quality, massive size, and user interface for this price point. If you’re on the fence, do yourself a favor and just go for it!

The TV is fantastic. The color is great. They have the stereo at the back of the TV so that TV is pretty loud and good sound quality which I like. It's a great TV for a great price.
