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 that covers
LG TV; OLED/QNED/LCD panel, webOS year, HDMI bandwidth and Magic Remote vary by model.

Published specification

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
2024 OLED evo with a Micro Lens Array (MLA) panel and the Alpha 11 AI Processor — one of LG's brightest 2024 OLEDs, well above the C4 and B4. Self-emissive, so a bright-window dim is the Auto Brightness Limiter, not backlight bloom.
Smart platform
webOS 24 with the Magic Remote; updates at Settings › Support › Software Update, screen share via AirPlay 2 and Miracast. LG guarantees several years of webOS Re:New feature updates on this generation.
Gaming / HDMI
Four HDMI 2.1 ports up to 144 Hz with VRR, ALLM, G-Sync and FreeSync. Requires Game Optimizer on and a 48 Gbps cable to leave 60 Hz.

Exact questions

Questions that only have an answer for the LG G4 OLED TV

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Is the LG G4 brighter than the C4?+

Yes. The G4 uses a Micro Lens Array (MLA) panel and the Alpha 11 processor, making it substantially brighter than the C4's conventional evo panel. Both are 2024 OLEDs on webOS 24 with four HDMI 2.1 ports up to 144 Hz, but the G4 is the higher brightness tier — a visible difference, not a fault on either.

Structured depth, not empty permutations

Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.

Device and manufacturer hubs share a consistent record system, but each answer carries the relevant controls, fault boundaries, consequences and official support entry point for that platform.
