What is true of this model and changes how you fix it
- Panel — QLED with local dimming (an actual TV)A full television: QLED with full-array/Mini-LED local dimming and Dolby Vision — good streaming and movie contrast. It has a backlight, so some blooming is normal, not a fault. Roku OS is built in.
- Smart platformRoku OS built into the TV. Update at Settings › System › System update; screen mirroring is Miracast and AirPlay 2.
- Gaming / HDMI — 60Hz, no VRRThe decisive difference from the Pro Series: the Plus Series is a 60 Hz panel with HDMI 2.0 — NO 4K 120 Hz and NO VRR. It supports Dolby Vision and Dolby Atmos for movies, but a request for 120 Hz or VRR is a hardware limit, not a setting or a fault.
- PortsThree HDMI plus one HDMI eARC, USB-C, cable/antenna, an optical output and a headphone jack, with Bluetooth. Roku lists a variable refresh rate for smoother gaming on this generation.
- MountingVESA 300 x 300 mm on the 55, and 400 x 300 mm on the 65 and 75.
- No streamer neededThe Roku player is built in, and a connection (Wi-Fi or Ethernet) is needed to stream. There is no monthly fee for the TV itself.
- Which generationThis hub's earlier spec rows were read for the R6AX generation, so check the model label (R6C7 is the current one) before relying on the refresh-rate row.

Exact questions
Questions that only have an answer for the Roku TV line and players (Plus Series, Pro Series, Ultra and Express)
Why can't my Roku Plus Series TV do 120Hz or VRR?+
The Plus Series is a 60 Hz TV with HDMI 2.0, so it does not have 4K 120 Hz or VRR — no setting enables them because the hardware lacks them. It is built for streaming and movies (QLED, local dimming, Dolby Vision, Dolby Atmos) rather than high-refresh gaming. The step-up Roku Pro Series adds the 120 Hz panel and HDMI 2.1 for that.
