Desktop is cut-off when using 16:9 ratio

[yaroslavvb]

Whenever I set resolution to 1280x720, left and right areas of the desktop in Vista get cut-off, so I can see only a part of the "Start" button. However, when I play Blu-Ray full screen (using HP Smart DVD player), it shows the frame correctly. Is there an easy fix?

Use the buttons and dials on the front of your monitor to shrink
the image. They're labeled something like "horizontal size/position".
Sometimes you can do this in software if your video drivers support it.
Look at control panel -> display -> properties -> advanced.

On my monitor I have to go into the settings and change the aspect ratio
from 16 : 9, or 4 : 3 to an aspect ratio of 1 : 1.

No it would be a button on your monitor.

Gary, is this on Vista? I can't find any setting which lets me specify "aspect ratio"

Thanks, this was indeed the issue of the projector fixed by adjusting Overscan/Output Scaling settings
