my screen got smaller on all resolutions

[liksi]

Hi.
Three months ago everything on my pc got smaller (letters, icons, mouse...).
It happened on all resolutions. I use resolution 1280x720 on 22'' , widescreen.
It is such small res. becouse it is hard to see un bigger ones.
Now i have that size on res. 800x600 so i have to switch every little. So now i cant see on 1280x720 and on 800x600 cant see video and images correctly.
I made ssand sent it to my sister and it was as it has to be.Also used her monitor but with same result.
Can someone please help me to solve this?
Thanks.

First thing you have to do is set the monitor to its native resolution.

Are the latest video drivers installed on your PC ?

What video card are you using ?

Please post a manufacturers link to the monitor.

Or at least tell us EXACTLY what it is.


Please fill in your specs, completely.
