Additional useful information
Use this exact-model guide to set up Sony K-55XR80M2, apply its 120 Hz native panel HDMI limits, connect eARC through HDMI IN 3, and check its 300 x 300 mm mount, tabletop stand, RMF-TX820U remote, U.S. tuner and audio formats before ordering accessories.
Sony K-55XR80M2 is the fifty-five-inch U.S. BRAVIA 8 II from 2025. Its hardware combines a 4K QD-OLED panel, XR Processor, and 120 Hz native panel. HDR support is Dolby Vision, HDR10 and HLG. The connection table lists four side-facing HDMI inputs; HDMI 3 and 4 support 4K at 120 Hz and VRR, all four list ALLM, and HDMI 3 is eARC/ARC, plus two USB ports, optical digital audio, Ethernet and one RF input. Audio compatibility is Dolby Audio, Dolby Atmos, DTS Digital Surround, DTS Express, DTS-HD Master Audio, DTS-HD High Resolution Audio and DTS:X. BRAVIA 8 II uses its OLED screen as part of the Acoustic Surface Audio+ system and reserves 4K120 and VRR for HDMI 3 and 4; HDMI 3 is also eARC/ARC.
Set the television up with the exact Quick Setup or Reference Guide for K-55XR80M2. The tabletop parts use a two-way outside or outside-for-soundbar Aluminum Edge stand position; another size's legs or attachment pieces should not be treated as interchangeable. For an audio system, connect the soundbar or receiver to HDMI IN 3, the port explicitly labeled eARC/ARC, then enable the BRAVIA audio-system and eARC settings. Google TV setup needs a network connection and may use a Google account; broadcast setup for this U.S. model is ATSC and U.S.-region ATSC 3.0 terrestrial plus Clear QAM cable reception.
Troubleshooting starts with the connection path: when video is absent, check the selected input, source resolution and HDMI signal format before replacing hardware. On HDMI 3 or 4, 4K120 and VRR also require a source and cable that support those modes. For audio faults, confirm HDMI 3 and the source/audio-device format settings. Try a normal restart and current firmware before factory data reset; reset removes accounts, apps, networks and customized settings. Sony lists a 300 x 300 mm VESA pitch, but its exact wall-mount guide remains authoritative for attachments, spacers, screw engagement, ventilation and wall structure. Sony USA identifies RMF-TX820U for this model, with a purchase-region caveat.
