42" OLED C6 for gaming and cinema

The LG OLED42C6PUA is a 42 inch OLED TV built for 4K resolution at 120 Hz. It targets gamers and film enthusiasts who want perfect blacks and accurate colour from self-lit pixels. The a11 AI Processor 4K Gen3 drives AI upscaling and picture tuning. WebOS 26 handles smart features and streaming apps.

HDMI 2.1 bandwidth and 165 Hz VRR limit

Four HDMI inputs support 4K at 120 Hz and variable refresh rates up to 165 Hz for PC gaming. The panel reaches 120 Hz natively, so consoles run at their maximum frame rate. Wi-Fi 5 and Ethernet provide network connectivity. The 2.0 channel speaker system uses Dolby Atmos processing for simulated surround sound.

Replaces older OLED or high-end LED sets

This model upgrades from earlier OLED panels that topped out at 60 Hz or lacked HDMI 2.1 features. The jump is worth it when you need 4K 120 Hz gaming, VRR above 120 Hz, or the latest AI processing. Buyers who need more screen area or brighter peak output for sunlit rooms should look elsewhere.
