Overview
85Q671G from TCL pairs a 84.6-inch 4K screen with VA display hardware and a Direct LED backlight. Google TV provides the app interface, while AIPQ Pro with AI handles picture processing and navigation. Quantum Dot colour strengthens the specification beyond a basic LED LCD, although no measured gamut figure is published. HDR support includes Dolby Vision, HDR10+, HLG, but neither typical nor peak brightness is published, so visible HDR impact remains uncertain. Gaming reaches 48 Hz - 144 Hz with AMD FreeSync Premium Pro, making the TV suitable for current consoles and many gaming PCs. Installation planning should account for the 600 x 400 mm VESA pattern and 35.1 kg / 77.38 lbs panel weight. Buy it if you want QLED colour and high-refresh gaming on a 84.6-inch screen; skip it if you need published brightness figures before judging HDR strength.

HDR & Brightness Reality
TCL 85Q671G accepts Dolby Vision, HDR10+, HLG, giving it broad compatibility with current streaming, disc and broadcast sources. The Direct LED backlight is conventional LCD hardware, so HDR impact depends heavily on brightness and contrast rather than format logos. Neither typical nor peak brightness is published, so the table confirms compatibility more clearly than visible HDR intensity. No DCI-P3 measurement is supplied, so colour-volume claims should remain conservative.
