This sample is thin—only 3 mentions—but they consistently surface a specific HDMI compatibility issue affecting certain LG and Samsung TV models: the receiver's menu won't display on-screen when accessing setup via HDMI. Owners report workarounds (connecting through a different HDMI input or using a third-party control app), but this creates friction during setup and calibration. The receiver's video and audio specs are strong, and owners haven't flagged broader quality concerns. If you have a newer LG C-series or Samsung OLED TV, verify compatibility before purchasing, or plan for alternate control workflows.
