Commen= t # 2 on bug 10530= 2 from Harry Wentland 
I don't have the spec right now but wikipedia has a nice run-d=
own of the DVI
bounding box: https://en.wikipedia.org/wiki/Digital_Visual_Interface#Digita=
l

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

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