Overview
Published 300-nit brightness gives the TCL 65Q77K a rare measured anchor in the Q77K range. The Direct LED VA panel supports Dolby Vision, HDR10+, HDR10, HLG, with Native - 120 Hz native refresh and 48 Hz - 144 Hz (hertz). FreeSync Premium Pro, HDMI Forum VRR, G-Sync compatibility and ALLM strengthen gaming, while 2 x HDMI 2.1 + 2 x HDMI 2.0 covers sources. Google TV and the AIPQ with AI processor handle streaming and upscaling. The 300 cd/m² (candela per square meter) brightness figure limits HDR headroom despite broad format support. Against the 55Q77K, the practical differences are screen size, stand footprint, weight and VESA pattern rather than the core family platform. Buy it if 120 Hz-class gaming and a large Direct LED screen matter more than Mini LED; skip it if strong, measured HDR performance is the priority.

HDR & Brightness Reality
The 65Q77K accepts Dolby Vision, HDR10+, HDR10, HLG on a Direct LED VA panel. 300 cd/m² (candela per square meter), while local-dimming hardware is not listed. The 120 Hz-class panel benefits motion and gaming more than HDR contrast. Dolby Vision and HDR10+ confirm format support, but the missing or modest luminance data means buyers should not expect Mini LED-level highlights or black control. Bright-room performance therefore remains uncertain from the sheet alone.
