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
- XBR-55/65/75/85X900H
- 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 — full-array LED LCD
- 2020 full-array local-dimming LED LCD with the X1 Ultimate processor. A backlight with limited zones, so raised dark-room blacks and blooming are normal for the tier, not a fault.
- Smart platform — Android TV (older)
- This is the oldest Sony here and runs Android TV, the platform before Google TV. Update at Settings › Device Preferences › About › System update. On a 2020 Android TV, an app that stops working is often the provider ending support for that OS version — check the Play Store for an update before assuming a fault; a cheap external streamer restores anything withdrawn.
- Gaming / HDMI — 4K120 and VRR added by firmware
- Two HDMI 2.1 ports for 4K 120 Hz. Both 4K 120 Hz and VRR were enabled by later firmware updates — if they are missing, update the TV first (this set shipped before those features were switched on).
- Dolby Vision — yes
- Supports Dolby Vision, HDR10 and HLG — unlike Samsung.

Exact questions
Questions that only have an answer for the Sony X900H 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.
My Sony X900H won't do 4K 120Hz or VRR.+
The X900H shipped in 2020 before those features were enabled and received them through firmware updates, so update the TV first: Settings › Device Preferences › About › System update. After updating, turn on the enhanced HDMI format for the port your console is in and enable VRR in the source. Both live on the two HDMI 2.1 ports; the older HDMI 2.0 ports cannot do them.
