All 4 HDMI inputs are identical and 2.1 compliant for up to 4K/32 bit 120Hz operation.
Sorry, there was a problem. Please try again later.All HDMI ports are given the 2.1 label so all are great for 4k HDR at 120 hz. You'll need to dig a bit in the menu for the connections tab and go into the HDMI settings to set each to its fullest capability though. No idea why it would be set default to actually display at a lower quality than it is capable of but that is how a few brands come OOTB. Only one port has eARC the rest have ARC for HDMI passthrough for external audio setups.
Sorry, there was a problem. Please try again later.All 4 ports support 4k 120hz.

Navigate to Settings > All Settings > Connection > External Device Manager > Input Signal Plus = On. ~ Samsung Specialist
