I don't have the spec right now but wikipedia has a nice run-down of the DVI
bounding box: https://en.wikipedia.org/wiki/Digital_Visual_Interface#Digital

Basically 2560x1600 @ 60Hz is the highest allowed for dual-link, which is just
a tad above your 2560x1440 @ 60Hz. 110Hz at full resolution would definitely
not be supported by DVI.

What monitor are you using? Is it intended to support 110Hz at full resolution
on DVI? Could it be that this full monitor capabilities are only supported
through DP?
