Overview
One specification mismatch shadows the LG OLED77G6WUA, a 76.77-inch 4K OLED evo television. The native 10-bit colour self-emissive panel supports 99.5 % (percent), Dolby Vision and four HDMI 2.1 inputs, with FreeSync Premium, G-Sync compatibility, VRR and ALLM. webOS 25, the α11 Gen2 4K AI Processor and 4.2 CH audio define the smart and sound package. Its webOS 25 and α11 Gen2 listing differs from the other G6 sizes and needs verification. Installation needs planning because the stand footprint is 1712 mm (millimeters) by 320 mm (millimeters) and weighs 39.7 kg (kilograms). Buy it if gallery-style OLED and 48 Hz - 165 Hz gaming justify the installation; skip it if the sheet’s peak-brightness conditions must be independently clear.

HDR & Brightness Reality
OLED77G6WUA combines self-emissive OLED evo, 10 bits, 99.5 % (percent) and Dolby Vision IQ, Dolby Vision, HDR10, HLG (Hybrid Log Gamma). The sheet quotes 2400 cd/m² (candela per square meter), but supplies no measurement window or duration, so it cannot be treated as sustained full-screen output. Pixel-level dimming gives OLED a credible black-level foundation, while Dolby Vision covers dynamic-metadata material. HDR10+ is absent, and the specification remains incomplete for comparing sustained brightness across the G6 sizes.
