Samsung SyncMaster 213T font size adjustments

I was looking at the above monitor in the store today and the fonts are tiny due to the high native resolution of 1600 X 1200.  I want to retain the resolution but enlarge the fonts and I tried to do that by going into "View" in Explorer and then "Text Size" and then "largest".  Nothing happened to the text size.  I need to know if that is normal or not. Can text size be adjusted in LCD monitors thru Explorer or does it stay tiny unless you decrease the resolution which I have been advised not to do.  Thank you for your help.
