Is Radeon 680m capable of 4K/120hz/10bit/4:4:4 through HDMI?
I'm going to buy a laptop for my TV LG C2, but I'd like to avoid discrete cards because I don't do gaming. Laptop ASUS VivoBook S 16X M5602RA-KV020W have Radeon 680m on board, but Asus dealer in my country don't know this information.
Radeon 680m integrated graphics supports HDMI 2.1 as long as your HDMI cable and TV supports it also. So with the right cable and TV both capable of HDMI 2.1 it should be possible but with new technology YMMV (Your mileage may vary). Translation: It may or may not work. Also, 4:4:4 RGB requires 10 HDR for 10bit at 4K/120hz.
