Dell U3417W Monitor + R9 280X Graphics Card - Cannot achieve 3440x1440 resolution

Hi there,

I have the following:

OS: Linux Mint 18.3 Sylvia MATE 64-Bit

Monitor: Dell U3417W
http://www.dell.com/ed/business/p/dell- ... monitor/pd

Graphics Card: HIS IceQ X2 R9 280x
http://www.hisdigital.com/id/product2-772.shtml

Using the HDMI port, I cannot get a 3440x1440 resolution. 2650x1080 works. I have tried creating modes with lower refresh rates to no avail. The monitor will just go black until I disconnect/reconnect the HDMI port. I'm using a secondary monitor on the DVI port for troubleshooting.

If I use the Integrated graphics HDMI port on my mobo, I can get 3440x1440 no problem.

If someone can get me started, I can post some log dumps here...

Looks like I might just be out of luck with how little this graphics card is supported, as per the sticky.
