About this item

Product details

The C5 is LG's mainstream OLED evo for 2025, and at 77 inches it delivers a home-cinema picture without the price of the flagship G-series. Every one of its 8.3 million pixels lights itself, so black is genuinely black and contrast holds from any seat in the room.

The Alpha 9 AI Processor Gen8 handles upscaling and tone mapping, and all four HDMI 2.1 ports run 4K at up to 144Hz with variable refresh rate. A PS5, an Xbox Series X and a gaming PC can all stay connected, with a soundbar on the eARC port.

Sold and shipped by ComBuy. Free shipping on orders over $35.

Questions & answers

Does the stand come in the box, or do I need a wall mount?

A pedestal stand is included and attaches to the bottom center of the panel, so the TV can sit on furniture at least 48 inches wide. A wall mount is sold separately.

Can I really run 4K at 144Hz on all four inputs?

Yes. Every HDMI port on the C5 is a full 48 Gbps HDMI 2.1 input, so a console on one port and a PC on another can both run high refresh rates without swapping cables.

Should I worry about OLED burn-in?

Normal mixed viewing is fine. The set runs pixel-refresh routines automatically and includes logo-dimming and screen-shift protections. Avoid leaving a static channel logo or game HUD on screen at full brightness for many hours a day.

How many people are needed to unbox and set it up?

Plan on two. The 77-inch panel is thin and light for its size at roughly 52 pounds, but it is nearly 68 inches wide and should be lifted from both ends, never by the center of the screen.

Does it support Dolby Vision for gaming?

Yes. The C5 accepts Dolby Vision game signals at 4K and can run them alongside VRR, so consoles that output Dolby Vision in game mode are supported.
