Ok, running the following: Nvidia GTS250 on Acer 23" monitor, Nvidia 6800GTS on Panasonic 42" 1080 plasma. set to extend desktop on both monitors, acer set as the primary monitor. Windows 7. I have mediaportal set up to open automatically on the panasonic monitor, now here's the glitch, if the acer monitor is on and I shut off the panasonic tv, nothing happens, everything is good, if i shut off the acer monitor however, the next time I turn it on mediaportal has jumped to that monitor. I ran into this problem before when running mediaportal on XP, but I can't seem to find the workaround this time.
