Our take on the LG 77" OLED77CXPUA 4K OLED ThinQ AI Smart TV
The LG CX is a 77-inch 4K OLED TV from LG's 2020 lineup, sold here as the OLED77CXPUA. OLED pixels switch off individually, so blacks are true black and contrast is effectively unlimited, which is what sets it apart from LED rivals at this size. It runs webOS with ThinQ AI, supports the major HDR formats and HDMI 2.1 features that matter to console gamers. It suits movie watchers and gamers who want a big, high-contrast screen and can control light in the room.
- Per-pixel OLED contrast with true blacks
- Four HDMI 2.1 ports for 4K high-frame-rate gaming
- Wide viewing angles with little color shift
- webOS with ThinQ AI voice control and major streaming apps
- Slim panel that mounts close to the wall

Questions and answers
- Is the LG CX good for gaming?
- Yes. It has four HDMI 2.1 ports, low input lag and support for high frame rates at 4K, which suits current consoles and PCs.
- Does it support HDR?
- It supports the main HDR formats, including Dolby Vision, HDR10 and HLG, so most streaming and disc content plays in HDR.
- Can OLED burn in?
- Static logos, tickers and game HUDs left on for long periods can leave faint marks. Varying content and using the screen's care settings reduce the risk.
- Is it bright enough for a living room?
- In a room with controlled light, yes. In a very bright room with direct sun, an LED TV will look punchier.
- What is in the box?
- The TV, its stand, a remote and the power cable. A wall mount and cables for other devices are not included.
- How does it compare with the C1?
- The C1 is the later model with a newer processor and slightly better processing. Picture character is close, so the CX remains a strong choice.
