If you have a receiver or a soundbar that is using ARC or eARC for audio from the TV, you are left with one HDMI 2.1 port. HDMI port 3 is HDMI 2.1 (120Hz) and the eARC port. Only have to disable a few things like the ambient light sensing and energy saving, and a few processing settings that are personal preference. The A80J in custom picture mode and Expert1 color temp is very good. According to a Sony rep I spoke to at the 2021 TV shootout, the 77" A80J has a similar panel binning process to that of the A90J. Based on review data, personal measurements, and user data here it seems Sony lets the "WBE" panels get brighter without software restricting them like LG with the C1 (or if they do, not as much). All 77" A80Js should be the newer "WBE" panel. The 55" and 65" have a panel lottery of older "WBC" or "3S3C" LG Display WRGB OLED panels, and the newer "WBE" or "3S4C" panel. In content should not really appear different.

The 55/65 models have a "semi gloss" screen coating, meaning instead of looking like a clean sheet of glass it looks slightly softer but only in reflection handling. The A80J is available in 55", 65", and 77" sizes.
