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: KD-43/50/55/65/75/85X85K
What that covers: Sony BRAVIA TV; Google TV/Android TV version, XR processor, panel and HDMI 2.1 ports vary.

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 — LED LCD, native 120Hz: 2022 LED LCD with a native 120 Hz panel and the X1 processor (not the higher Cognitive Processor XR). A backlight with limited local dimming, so blacks are less deep and blooming more visible than XR/Mini-LED models; that is the tier, not a fault.
Smart platform: Google TV. Update at Settings › System › About › System software update; Chromecast built-in and AirPlay 2.
Dolby Vision — yes: Supports Dolby Vision, HDR10 and HLG — unlike Samsung.
Gaming / HDMI: Two HDMI 2.1 ports for 4K 120 Hz; it is one of Sony's more affordable 120 Hz panels. Put the console on an HDMI 2.1 port (the higher-numbered ones) and enable the game/enhanced format for that input.

Exact questions

Questions that only have an answer for the Sony X85K 4K 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.

Does the Sony X85K support 4K 120Hz gaming?+

Yes — the X85K has a native 120 Hz panel and two HDMI 2.1 ports that do 4K 120 Hz, which is unusual at its price. Connect the console to one of the HDMI 2.1 inputs, use a certified Ultra High Speed cable, and turn on the enhanced/HDMI format for that input so it accepts the higher-bandwidth signal.

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.
