TCL C8L 65-inch / LG OLED77B5PUA (B5, 77-inch)

In OLED each pixel makes its own light and can switch off completely, so blacks are much deeper than on backlit LCDs.

288 Hz does not promise 4K resolution.

Energy-label default, not the maximum input rate.

Requires a compatible source, game and suitable HDMI input.

On the marked HDMI port; CEC must be enabled.

Standard energy-label measurement, not constant consumption for every scene.

Not a promise of eight major operating-system versions.

VRR matches the screen’s refresh to the frame rate of a console or PC, reducing tearing.

Picture processing, upscaling of lower-resolution content to 4K and audio up-mixing run on this chip; it sits below the processors in the C and G series.

HDR10+ is not in LG’s list; content mastered in HDR10+ plays as standard HDR10.

ALLM automatically switches the TV to a low-latency mode when a connected console starts a game; HGIG leaves HDR tone mapping to the game itself.

eARC sends audio from the TV’s apps, including Dolby Atmos, losslessly to a compatible sound system.

RS-232C and IP control let home automation systems manage the TV.

Wi-Fi 6E can use the less crowded 6 GHz band with a compatible router; Bluetooth is used for headphones and speakers.

Virtual 9.1.2 is processing that tries to create a multi-channel impression from two speakers; there are no real height or rear speakers.

LG promises software updates and feature refreshes under its Re:New program; most apps require an internet connection and an LG account.

Actual consumption varies with content brightness and picture mode; the annual figure is based on US test conditions.

The stand is 55.2 inches (about 140 cm) wide; the furniture it sits on must be at least that wide.

Use the weight without the stand when choosing a wall mount.

The VESA size is the horizontal and vertical spacing of the screw holes on the back; the mount must support it.

No HDMI cable is listed.
