Windows 8 on a CRT

I have a 21" CRT monitor and just installed Windows 8. Does anyone have a solution to having enough resolution for the new snap mode that doesn't render the rest of the interface in a ridiculously tiny fashion? I mean, the text I'm typing right now, on the desktop Firefox is miniscule. I can enlarge it with CTRL +, but that doesn't increase the overal UI.

Any ideas?
