I have an Asus ROG 2080 Ti Rtx, and a Samsung Odyssey G7 32" monitor (supports 2560x1440 @240hz). When I connect HDMI with an 18Gbps cable, it won't do 240 Hz (stuck at 144Hz). The monitor came with a displayport cable, and initially I hooked that up- it worked at 240 Hz. After restarting the computer the displayport cable stopped working for some yet unknown reason (I just see a black screen / no viewable input despite that it looks like it's getting a signal), so I swapped back in HDMI. I've tried swapping back in the displayport cable several times but can't seem to figure out the issue. I currently am not aware of a reason the HDMI connection can't support 2560x1440 @240hz other than that I suspect the new 48Gbps cables may be needed for this (my current HDMI cables are the 18Gbps type). Anyone know about specifics of this?
