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.

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 — LCD, not OLED
- An LCD with standard full-array local dimming — NOT Mini-LED like the QNED90T, and not OLED. It has fewer, larger dimming zones, so blooming and halos around bright objects on dark backgrounds are more visible than on the QNED90T and far more than on any OLED. That is expected LCD behaviour, not a defect.
- Smart platform
- webOS 24 with the Magic Remote — same apps, update path and AirPlay 2 / Miracast screen share as the rest of LG's 2024 line.
- Gaming / HDMI
- HDMI 2.1 with 4K 120 Hz, VRR, ALLM and FreeSync. Game Optimizer on the input enables it.

Exact questions
Questions that only have an answer for the LG QNED85T 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 QNED85T Mini-LED?+
No. The QNED85T uses a standard full-array local-dimming LCD backlight, while the step-up QNED90T uses Mini-LED with many more dimming zones. That is why the 85T shows more blooming around bright objects and less precise contrast — a hardware difference between the two models, not a fault, and Local Dimming settings help manage it.
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.
