Good catch. I thought this might be a nice alternative to the CX with DP 1.4 + DSC support offering everything HDMI 2.1 can do without needing a HDMI 2.1 GPU but it definitely does sound like something has been gimped. What the hell is that "6G" about?I think I found a deal breaker for the FO48U. I noticed it's spec sheet stated 4K/120hz through HDMI + PS5/Series X was limited to 4:2:0 which is odd. I know PS5 is only capable of 32Gbps (4K/120hz 4:2:2) but the Gigabyte is straight advertising HDMI 2.0 bandwidth for it's 2.1 ports. Even more confusing is this statement in the manual which is absent on the FV43U. Looks like it has some gimped HDMI 2.1 implementation.
Who knows what this means and how it translates when actual devices are connected but I'm not really interested in being a guinea pig.
EDIT: FV43U product page specs also states consoles are limited to 4:2:0 but manual does not include the riddle me this input notes found in the FO48U manual.
