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: 43/50/55/65/75UR9000*
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 — entry LED LCD: An edge-lit LED LCD — the entry tier, with no local dimming, an OLED, or Mini-LED. Blacks are grey in a dark room and uniformity/backlight clouding is more visible than on higher models; that is the limit of edge-lit LCD, not a defect.
Smart platform: webOS 23 with the Magic Remote — the app store, update path (Settings › Support › Software Update) and AirPlay 2 / Miracast are the same as LG's premium sets.
Gaming / HDMI — no HDMI 2.1, no VRR: This is the decisive limit: the UR9000 has a 60 Hz panel and three HDMI 2.0 ports, with NO HDMI 2.1, NO 4K 120 Hz and NO VRR. A request for 120 Hz, VRR or ALLM on this model is a hardware limitation, not a setting to fix or a fault — those features do not exist on it.

Exact questions

Questions that only have an answer for the LG UR9000 UHD 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 can't I get 120Hz or VRR on my LG UR9000?+

The UR9000 does not have those features. It is an entry LED TV with a 60 Hz panel and HDMI 2.0 ports — no HDMI 2.1, no 4K 120 Hz and no VRR or ALLM. Nothing in the settings will enable them because the hardware does not support them; 4K 60 Hz is its ceiling. High-refresh and VRR need one of LG's OLED or QNED models.

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.
