After seeing your pictures Paco it made me go and hook up an old lcd 17inch as 2nd monitor. Now if only more games worked with dual monitor setup. Silent Hunter 5 should of had this, map on one screen while on the bridge with the other or when @ periscope on one screen with external view on the other though that last would be a bit of a cheat.

I could think of 20 different setups playing SH5 with dual monitors. I must google on what games run with dual monitors, I know that Supreme Commander & Dragon Age 2 work.
