Sony A80L/A80CL OLED Review (XR-55A80L, XR-55A80CL, XR-65A80L, XR-65A80CL, XR-77A80L, XR-77A80CL, XR-83A80L, XR-83A80CL)

The TV supports full HDMI 2.1 bandwidth on HDMI ports 3 and 4, while HDMI ports 1 and 2 are limited to HDMI 2.0 bandwidth. As HDMI 3 is also the eARC port, you lose an HDMI 2.1 slot if you connect a receiver to it, which means that you can’t use multiple HDMI 2.1 devices simultaneously when an audio receiver or soundbar is connected to the eARC port unless the receiver has HDMI 2.1 ports with pass through. The tuner supports ATSC 3.0, allowing you to stream over-the-air 4k channels.
