I am using Windows 7 on a Sony VAIO VGN-AR51M and I am wondering if you know of a way of enbaling rotation of the display so I can use my external monitor in portrait mode.
Ctrl+Shift+Left/Right/Up/Down doesn't work. Using a program called "iRotate" doesn't work either.
Using Vista it took myself many hours of searching before I found a registry tweek and then iRotate did the job. However since I clean installed Windows 7 I don't know what to change in the registry to enable it again.
I have e-mail Sony and they have said that rotation is not possible even though I did it before.
I am using an Nvidia 8400M GT GPU, but the control panel does not offer me any rotating option.
I came across a forum that mentioned to change the registry entry "RotateFlag" from 1 to 4 (which may have been what I did before, but I am not sure), but that didn't work.
If you have any suggestions to help me with this matter, I would be very grateful.
