Do you know what the max supported resolution is of both monitors? If both are capable of the same resolution then it may simply be that the one with the current wrong resolution needs to be changed in the display setup to match. I think the nvidia-settings tool can also adjust the monitor resolutions (if you are using the nvidia driver). When connecting different monitors they seem to often pick the wrong (not max) resolution, and I have had to go into display settings and change it.
The sub-optimal solution would be to change the higher res monitor to the same resolution of the lower resolution monitor (ie pick a common supported resolution for both monitors) but that would lose quite a bit of pixels.
