HDMI and DisplayPort monitors

[joshualibrarian]

Hello! I have installed the newest mint (14.1 x64) on this very nifty little "fit-pc3" computer. It works very well except for this little problem with one of the monitors. I have two IDENTICAL monitors plugged into the two different video ports, one into the HDMI and the other into the DisplayPort. The monitor plugged into the HDMI identifies fine in the graphical monitor configuration (listing as 'RIS 19"'), with various resolutions available up to 1360x768. The other monitor however (again, the exact same kind of monitor) which is plugged into the DisplayPort shows as "Unknown" with a maximum resolution of 1024x768. I want both monitors at 1360x768! Any ideas?

Here is the output of "xrandr":

Code: Select all

And here is the output of "inxi -G":

C'mon, 44 views and no responses. Please!

Furthermore, when I suspend the computer and bring it back up, the monitor no longer shows as "unknown", however the monitor's image is off-center, and the adjustment on the monitor can't bring it back into line.
