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.

- What that covers
- Roku player or Roku TV family; remote type, Wi-Fi radio, Ethernet and Dolby formats 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 — Mini-LED QLED (an actual TV)
- Unlike Roku's streaming players, the Pro Series is a full television: a QLED with a Mini-LED backlight and local dimming. It has a backlight, so blooming/halo around bright objects and raised dark-room blacks are normal LCD behaviour, not a fault. Runs Roku OS built in.
- Smart platform
- Roku OS built into the TV. Update at Settings › System › System update; screen mirroring is Miracast and AirPlay 2. No separate streaming device is needed.
- Gaming / HDMI
- A 120 Hz panel with HDMI 2.1 supporting 4K 120 Hz, VRR and ALLM, plus Dolby Vision IQ — Roku's only high-refresh gaming TV. Enable Game Mode / Auto Low Latency for the input.

Exact questions
Questions that only have an answer for the Roku Pro Series 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 Roku Pro Series TV do 4K 120Hz gaming?+
Yes — the Pro Series is Roku's flagship TV with a 120 Hz Mini-LED QLED panel and HDMI 2.1, so it supports 4K 120 Hz, VRR and ALLM. Connect the console to an HDMI 2.1 port with a certified cable and enable Game Mode. This is the gaming difference from the cheaper Plus Series, which is a 60 Hz HDMI 2.0 TV.
