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.

Model numbers and patterns: OLED55/65/77/83/97G5*
What that covers: 2025 LG TV; OLED/QNED panel, webOS release, HDMI bandwidth and Magic Remote vary by model and size.

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: OLED evo with LG's 2025 Primary RGB Tandem (four-stack) panel and Brightness Booster Ultimate — LG's brightest OLED, rated around three times the brightness of the B-series in a 10% window. Because it is self-emissive there is no backlight to bloom or clould, so a 'dimming' complaint is almost always the Auto Brightness Limiter pulling back a large bright window (normal OLED behaviour) or Energy Saving / ambient light sensing, not a backlight fault.
Smart platform: webOS 25 with the Magic Remote (pointer + voice). Update path is Settings › Support › Software Update; screen sharing is built-in AirPlay 2 and Miracast. App, cast and remote instructions written for Samsung Tizen, Google TV or Roku TV do not map to webOS.
Gaming / HDMI: Four HDMI 2.1 (48 Gbps) ports supporting up to 165 Hz, VRR, ALLM, NVIDIA G-Sync and AMD FreeSync Premium. High-refresh/VRR only engages when the input's Game Optimizer is on and the source is on an HDMI 2.1 port — a 'no 120/165 Hz or VRR' report is nearly always that mode or a sub-2.1 cable, not the panel.
eARC: eARC is on HDMI 2. A soundbar or receiver that loses Dolby Atmos or ARC audio should be on that specific port with HDMI-CEC (SIMPLINK) enabled on both devices before the fault is treated as hardware.

Exact questions

Questions that only have an answer for the LG G5 OLED evo 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.

Why does my LG G5 dim during bright scenes?+

That is the OLED Auto Brightness Limiter, not a fault. When a large part of the screen is very bright, the TV limits total panel power to protect the pixels and manage heat, so a big white window dims slightly. It is normal OLED behaviour on every LG OLED, including the brightest G5. Turning off Energy Saving and the ambient light sensor reduces other automatic dimming, but ABL on full-screen brightness cannot be disabled.

My LG G5 won't run 4K 120Hz or VRR from my console/PC.+

Connect the source to one of the HDMI 2.1 ports with a certified 48 Gbps Ultra High Speed cable, then turn on Game Optimizer for that input (Settings › General › Game Optimizer). VRR, ALLM and the 120–165 Hz modes only activate when that mode is on and the source is set to output them; the panel supports up to 165 Hz but it will sit at 60 Hz until the input mode is switched.

Structured depth, not empty permutations
