I need to upgrade my graphics to be able to display 5120x1440 @ 60Hz on DELL U4919DW monitor.
My current graphics is an AMD Radeon 7850 card and can only display up to 3840x1080.
What AMD cards can support a 5120x1440 resolution?
Did you ever figure out a solution? I am having the same issue with a Samsung 49" Ultra wide. I can get the 5120x1440 when connected to my laptop, but not from my desktop PC with Radeon 7700.
