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: K-55/65/77XR80
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 — WOLED: 2024 OLED (LG Display WOLED panel), successor to the A80L, with the Cognitive Processor XR. Self-emissive, perfect blacks, no backlight — so a large bright window dimming slightly is the Auto Brightness Limiter, not backlight bloom.
Smart platform: Google TV. Update: Settings › System › About › System software update; screen share via Chromecast built-in and AirPlay 2.
Dolby Vision — yes, including 4K 120 Hz: Supports Dolby Vision (plus HDR10, HLG, IMAX Enhanced), and does Dolby Vision at 4K 120 Hz for gaming — unlike Samsung, which has no Dolby Vision at all.
Gaming / HDMI — 2 ports, one shared with eARC: Two HDMI 2.1 ports (HDMI 3 and 4, 4K 120 Hz, VRR, ALLM); HDMI 3 doubles as eARC. Put the console on HDMI 4 if a soundbar is on eARC. 'Perfect for PlayStation 5' features included.
Panel: An OLED panel, where each pixel emits its own light. Dark mode genuinely reduces consumption because black pixels are switched off, and a static bright element left on screen for very long periods is the one wear risk this panel type has that LCD does not.

Exact questions

Questions that only have an answer for the Sony BRAVIA 8 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.

Can the Sony BRAVIA 8 do Dolby Vision gaming at 120Hz?+

Yes. The BRAVIA 8 supports Dolby Vision at 4K 120 Hz on its two HDMI 2.1 ports (HDMI 3 and 4), which is something Samsung TVs cannot do at all since they lack Dolby Vision. Put the console on HDMI 3 or 4, enable the source's Dolby Vision gaming output, and use a certified Ultra High Speed cable.

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.
