Overview
Seventy-seven inches of OLED evo panel make the LG OLED77C6HUP a large 4K webOS TV. Self-emissive pixels, 99.5 % (percent), 10 bits and Dolby Vision suit films, while 48 Hz - 165 Hz (hertz), FreeSync Premium, G-Sync compatibility, VRR and ALLM serve gaming. Four HDMI 2.1 inputs, eARC, webOS 26 and the α11 Gen3 AI Processor 4K form a strong source and smart-TV package. Typical and peak brightness are not published, so bright-room output and HDR highlights cannot be compared numerically. The OLED83C6HUP shares the core platform; size, weight, VESA pattern and gamut figure are the useful differences. With its stand, the set weighs 27 kg (kilograms). Buy it if OLED black levels and 48 Hz - 165 Hz gaming suit your room; skip it if published brightness data or HDR10+ is essential.
