In MP 1.2.3, when I switched from TV to projector, using DisplaySwitch.exe, MP automatically re-sized to the new resolution, in 1.4 (I skipped 1.3) it doesn't - it is some setting I can adjust in MP's configuration to get this functionality back?
I have the same problem. I dont use that resize.exe. Instead I had this setting checked: "restart MP on resume" which is gone now.
When I turned on the PC it would restart MP with the correct resolution.
Now I have to manually restart MP which is quite annoying...
