How is your monitor connected and what resolution is it?  Your board seems to
have two DP (displayport) connectors.  2560x1600 requires a dual link connector
if you are using DVI.  As your board does not have any dual link DVI
connectors, you can't run the monitor at 2560x1600 over a passive DP to DVI
adapter.  Passive DO to DVI adapters only support single link DVI.  You either
need to connect the monitor via native DP or an active DP to dual link DVI
