Somewhere in the bowels of Windows XP you will find.....
There is actually a solution to the icon size issue in Windows. That having been said, if the screen is set to the wrong resolution, icon size is a symptom, not a problem.
The monitor must be set to it's correct native resolution first, and only then can the icons be addressed.
My son bought a Mac, and I thought wow, the big icons are kind of cute. Although the bouncing s*** is really tacky.
XP offers 3 choices of icon size natively but you need to convince it that you're "handi- capable". The access is via "all programs"> accessories> accessibility> accessibility wizard. Basically, you run the wizard and tell XP you're blind. The choice of icon size is offered, as well as high contrast. big text and sundry other things.
You can also choose 2 sizes using; right click on desktop > properties > appearance> then the effects button, there's a check box for small or "large" icons. The large is actually the same as the "medium" size in the wizard. The actual "large" icons are about an inch in diameter, really way too large for a normal sighted person. I prefer the mediums and always use them.
Now, I checked the specs on all the 20" monitors at Newegg. Out of 9 standard 20" (4:3 aspect ratio) shown, 7 are 1600 X 1200 and 2 are 1400 X 1050. My own Westinghouse 20.1" (again 4:3 standard) is 1400 X 1050.
I couldn't find a 20" at 1440 X 900 so I stand corrected and chastened on that one. They are as SNGX1275 mentioned all 1680 X 1050. I think my confusion there is that 17" and 19" are both 1440 X 900. At 22" widescreen all are 1680 X 1050.
Anyway, as long as something close to the correct driver for the GT7300 is installed, the settings slider should show a stop at the correct resolution. This is a plug and play device we're discussing.
I had a bizarre graphics crash the other day (onboard Intel GMA 900) where first I had no video at all, and the system setting slider wouldn't pick up the monitors actual resolution. But, a couple of reboots and a couple of off, on cycles with the monitor cleared it up, no problem since. Once we attend to the correct native resolution and then find an icon size we can deal with everything should be just peachy. (Well, if if is actually peachy we better jack up the color temperature).
