Fresh reload, stuck back at 3840 x 1024

[Bewst]

I know it wasn't hard how I had it set in the first place but I cant remember how. I looked on here and I don't remember ever setting a custom resolution and having to adjust frequencies up or down until it worked on my computer.

I have flashed to the latest firmware off their site and have installed the latest drivers off of their site. This thing is wearing on my patience, lol

I need back at 5040 x 1050 where it was working fine before
