Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Panel
2023 OLED evo with a Micro Lens Array (Brightness Booster) panel — the brightest 2023 LG OLED, well above the C3 and B3. Self-emissive; a bright-window dim is the Auto Brightness Limiter.
Smart platform
webOS 23 with the Magic Remote. Updates: Settings › Support › Software Update. Screen share is AirPlay 2 and Miracast. Still receiving webOS Re:New updates.
Gaming / HDMI
Four HDMI 2.1 ports at 4K 120 Hz with VRR, ALLM, G-Sync and FreeSync, plus HDMI 2.1 QMS (Quick Media Switching) which removes the black-screen 'HDMI bonk' when the frame rate changes.
