Overview
For buyers comparing TCL TVs in this size class, the TCL 85Q51K combines a 84.6-inch 4K panel with quantum-dot LED backlighting and Google TV. Picture specifications include quantum-dot color, while HDR support covers HDR10 / HLG / HDR / Dolby Vision / HDR10+. For gaming, it lists 50 Hz / 60 Hz refresh, ALLM. The smart platform is backed by Realtek RTD2875P, 2 GB (gigabytes) RAM, 16 GB (gigabytes) / eMMC 5.1 storage. Connectivity includes 3 HDMI ports (2.0), 1 USB port, plus Wi-Fi, Ethernet and Bluetooth where listed. The supplied data does not publish a typical brightness figure, so real HDR highlight intensity cannot be ranked confidently from the specification sheet alone. It makes the most sense for streaming, TV and movie viewers who value the listed smart features and screen size.

- HDR compatibility includes HDR10 / HLG / HDR / Dolby Vision / HDR10+
