The LG C6 is a 77-inch 4K OLED evo TV built on LG's Primary RGB Tandem panel, which layers red, green and blue emissive stacks to raise brightness and color volume over earlier C-series OLEDs. It runs the Alpha 11-class AI processor with Hyper Radiant Colour and Brightness Booster, and covers the gaming basics well: four HDMI 2.1 ports, high refresh with VRR and ALLM, and Dolby Vision plus Dolby Atmos. It suits film fans and console gamers who want deep blacks and wide viewing angles in a large room. Against Samsung's QD-OLED S95 line it gives up some peak highlight punch but keeps perfect black levels and typically undercuts the brighter MLA-based G-series, which is the step up for very bright rooms.
