1280

Why does 1280 seem to be the standard resolution for DesktopX. I've tried using 1280 and my fonts are so small in Windows Explorer I can hardly read them. I've tried enlarging them, but that doesn't seem to work. Any suggestions anyone?

Most of it's because my refresh rate goes down to 60hz on high resolutions, though. Time for a new monitor.
