This may do as a temporary fix
Go to the Control Panel find the Folder called
Display There are several tabs on the next window
Click the one called
Settings OK?
There is a slide bar here with numbers beneath it.. move the bar to the left and observe the picture above should get bigger the numbers vary from computer to computer
"Normal" resolution is 1024x768 on most PCs (thats your target)Should be 2nd notch from the left?
Lowest resolution(everything big) is 800x600
I have a feeling yours has been set much higher
maybe 1280 x 720? and I agree You do have to squint!

Maximium on mine is 1280 x 1024 (8th notch)
So Move the bar till it says 1024x768 underneath then press the "Apply" button the Monitor may click off and on. Does that look better?

Go too low then you'll get scroll bars everywhere
Under normal circumstances its rare you have to adjust these settings the computer does it automatically.
