Additional useful information
Use this exact-SKU guide to set up Roku 55R4A5R, preserve its A-generation Select Series 4K limits, troubleshoot Roku OS, and match HDMI/eARC, antenna, remote, stand, VESA, screw, wall, and weight requirements safely.
Roku 55R4A5R is the fifty-five-inch U.S. A-generation Select Series 4K. It uses a 4K UHD direct-lit LED display, 60 Hz native refresh rate, HDR10 and HDR10+, and Dolby Audio. Roku's official product information lists four HDMI inputs, with one input serving eARC, plus USB and a cable/antenna connection. This 55-inch Select Series A-generation set remains a 60 Hz direct-lit model and must not be confused with the 55-inch Plus Series QLED. This generation boundary matters: no MiniLED, 120 Hz, or current C-generation feature is assigned to an A-series model unless its own record supports it.
For setup, install only the exact 55R4A5R tabletop parts or a separately verified wall mount, connect sources, choose the matching HDMI input, join the network, and follow Roku OS guided setup. Connect a soundbar or receiver only to the input physically labeled eARC. For broadcast reception, attach the antenna or cable lead and run a channel scan for the installation area; this record does not invent an ATSC generation or satellite tuner. The reviewed mounting table gives 400 x 300 mm, M6 x 16 mm, approximately 30 lb, and 28.4 x 48.5 x 3.2 inches without a stand. Those values do not replace the mount maker's load rating, wall-fastener, clearance, ventilation, and screw-engagement instructions.
If the screen is blank, confirm power, selected input, source output and cable seating, then perform a normal Roku TV restart. For network trouble, restart the router and TV and check for a system update. For persistent software problems, Settings > System > Advanced system settings > Factory reset removes accounts, apps/channels, network data and preferences. Roku also documents a physical reset-button recovery; use the exact support procedure rather than an improvised button press. A replacement remote must explicitly support Roku-branded televisions and the expected voice/TV-control functions, while replacement stand hardware must name 55R4A5R.
- Smart system: Roku OS with guided setup and app/channel updates
- HDMI: four HDMI inputs, with one input serving eARC; use the physical eARC label rather than an inferred port number
- Other input boundary: one USB connection and a U.S. cable/antenna input are listed in Roku product information
- Audio: Dolby Audio; format support must also be checked on the connected soundbar or receiver
- Mounting: Roku lists 400 x 300 mm, M6 x 16 mm, approximately 30 lb, and 28.4 x 48.5 x 3.2 inches without a stand for 55R4A5R
- Remote: included Roku voice remote; no replacement part number is inferred
- Reset: Settings > System > Advanced system settings > Factory reset; the physical reset button is a recovery option
