77-inch OLED C6 with 120 Hz panel

The LG OLED77C6HUP is a 77-inch 4K OLED smart television built around the a11 AI Processor 4K Gen3. It delivers over 8.3 million self-lit pixels with Perfect Black and Perfect Color performance. The set runs webOS 26 and includes the AI Magic Remote MR26 for voice and pointer control. It is aimed at viewers who want reference-grade contrast and wide-angle colour in a large living-room display.

Stepping up from 60 Hz LED sets to 120 Hz OLED

Replacing a conventional 60 Hz LED TV with this panel adds per-pixel dimming, a native 120 Hz refresh rate and the Brightness Booster Pro enhancement. The jump is worth it when you watch high-motion sports, play 120 fps console titles or need Dolby Vision IQ and Filmmaker Mode accuracy without backlight bleed. HDMI 2.1 bandwidth on four inputs supports variable refresh rate and auto low-latency mode for modern consoles.

Home cinema buyers who need 165 Hz PC gaming

This model suits film enthusiasts, streamers and console gamers who value perfect blacks, 2.2-channel Dolby Atmos sound and wide connectivity including Wi-Fi 5, Ethernet and RS-232C. It is not for PC gamers targeting 165 Hz 4K input, because the panel’s native refresh tops out at 120 Hz. Buyers needing more than four HDMI ports or a built-in ATSC 3.0 tuner should consider other options.

Questions about this item

What VESA pattern and clearance does the 77" OLED C6 need for wall mounting?

The TV uses a VESA 300x200 pattern and measures 67.4" wide, 10.5" deep and 40.7" high, so ensure the bracket supports that pattern and the wall cavity accommodates those dimensions.

Which HDMI ports on the C6 support 4K 120Hz input for a game console or PC?

All four HDMI inputs accept 4K 120Hz signals; connect the device, then open Game Optimizer and confirm the input icon shows 120 Hz to verify the handshake completed correctly.

How should the anti-reflective panel be cleaned without damaging the coating?

Use only the supplied ammonia- and alcohol-free cleaner with the included polar fleece cloth; spray the cloth lightly, wipe gently in one direction, and never apply liquid directly to the screen.
