LG OLED77B5PUA (B5, 77-inch) / TCL QM8K 65-inch (65QM8K)

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

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.

eARC sends audio from TV apps and connected sources to a soundbar or receiver over one cable, including lossless formats.

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

Bluetooth version is not stated.

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.

The sheet does not give total output power or channel count.

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.

The series comes in 65, 75, 85 and 98 inches; dimensions, weight, VESA and energy figures vary by size. This entry is the 65-inch North American model.

WHVA is TCL’s name for its wide-angle VA LCD panel; VA panels offer high native contrast but can lose contrast off-axis.

Mini LED dims thousands of small LEDs in zones for deeper blacks; halos (blooming) can still appear around bright objects. The series sheet says “up to LD3800” zones; the 65-inch page gives no zone count.

This is TCL’s marketing class and describes the peak reached on a small bright area. Independent measurements came in lower.

Dolby Vision IQ and HDR10+ carry scene-by-scene tone-mapping data; IQ also adjusts for room light.

The native panel rate is 144 Hz; 288 is the upper limit of Game Accelerator mode. The manufacturer page does not say which HDMI inputs support 4K 144 Hz.

These are North American broadcast standards;

About 23.1 kg with stand, 21.1 kg without.
