Isn't there another thing next to the 32 bit part??
mine says screen resolution on the left and color quality {32 bit} on the right
yours might say 1024 x 760 or something - or maybe that's only for LCD screens - i don't remember what mine said in that area with my old monitor.
If it isn't there no biggie - i was just curious...

Back to the problem at hand...
if you open the DI {display icon} can you read anything there? or is it all big too?

I think if I were you - I'd go back to what ever you changed and put as many of the settings back to the original sizes if you can.
Did you change the icon sizes on the appearance section and the DPI sizes too??

maybe go to the display , dpi and set it back to normal first & see if that helps.
then if it is still too big go to the appearance and try a change there or a new color/theme and test that.

Ok went back and re read - so you didn't change any dpi settings at all??
If not don't mess with that then-
- wherever you did make a change just go back to it and make the font or icons sizes smaller.
All you have to do is back track and find any places you made changes.
then only try one thing at a time and test it - if it doesn't work then put it back to what it was at then try the next place.
