Hi! This is my first post so I apologise for any noobishness.
My friend has a problem with her PC in that it seems to be outputting a 4:3 full screen image which is being stretched to fill the widescreen monitor its plugged into. The desktop is stretched and squashed and videos play stretched as well. There is also considerable screen tearing when watching videos. I've tried changing the display settings to every option available and none of them seem to make any difference. How can I fix this? If I remember correctly it's running Windows 7.
