Overview
Cinema-room scale is the reason to consider the TCL 98Q77K, a 97.5-inch 4K Direct LED TV. 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 Pro with AI processor handle streaming and upscaling. Brightness and contrast are not published, limiting any HDR performance comparison. Against the 85Q77K, 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 98Q77K accepts Dolby Vision, HDR10+, HDR10, HLG on a Direct LED VA panel. -, 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.
