It should be a set resolution anyway. Please don't think I'm busting your chops over half a millimeter.
It's about 82 dpi by my calculations, where 1920x1080 is very nice and readable. That's the kind of lower dpi my friend needs for UO. In the several years between leaving and returning, she bought a new system, and while a 22" widescreen was nice for WoW and Diablo III, she isn't used to things in UO being so small.
