The LG OLED evo AI C6H TV delivers high peak brightness and color accuracy despite limited AI functionality

The LG OLED evo AI C6H, specifically the 77-inch model, utilizes a tandem four-stack panel design to achieve significant brightness improvements over previous generations. Lab testing confirms the display reaches approximately 2,700 nits of peak brightness in Filmmaker mode and nearly 4,000 nits in Vivid mode. Color accuracy is high, yielding an average Delta E 2000 of 1.25 in SDR and a Delta E ITP of 8.58 in HDR. While the TV is marketed heavily on AI features, the integrated chatbot and hands-free voice control show notable limitations; they often fail to execute direct system commands like installing applications or adjusting motion settings, instead defaulting to web searches. The new "Personalized Picture Wizard" uses AI-generated images to set user preferences, though this may prioritize visual "pop" over natural reproduction. Physically, the C6H features a sturdy, heavy base stand and improved cable management compared to the G5 series. The redesigned remote control includes a dedicated AI button but lacks a physical mute button, requiring a long press on the volume key to silence the audio.

Physically, the C6H features a sturdy, heavy base stand and improved cable management compared to the G5 series. The redesigned remote control includes a dedicated AI button but lacks a physical mute button, requiring a long press on the volume key to silence the audio.

The LG C6H uses a tandem four-stack panel technology to reach peak brightness levels up to 4,000 nits in Vivid mode. Lab measurements show high color accuracy with a Delta E 2000 of 1.25 in SDR Filmmaker mode.

AI-driven features like the chatbot and voice control often fail to execute direct system commands such as app installation. The TV's 'Always Ready' mode allows it to display artwork and music equalizers while the screen is technically off.

The redesigned remote control lacks a dedicated mute button, requiring a long press on the volume key instead. Filmmaker mode provides the most accurate image reproduction while still reaching approximately 2,700 nits of peak brightness.
