Win 7 & Samsung monitor.

The on screen display leaves a 5 cm gap on the right of the screen.
I have tried Control panel / Resolution / Display settings.

Also, The monitor on screen display position settings.

Thats the important one.

When I try and drag the display it stops at the 5 cm gap so doesnt fill
the screen.

This has only started in the last couple of days.
Any ideas or is the monitor starting to fail?

Looks like it is starting to fail if you have cycled the power.
