Using Windows 7 Pro, 64 bit and a Dell U2410 monitor. Native resolution on the monitor is 1920 x 1200. Since I got the monitor three months ago, I've had it set for 1680 x 1050, as it's easier to see without having to wear glasses. Tongith, for some stupid reason (idle hands) I changed the color from 32 bit to 16 bit to se what the difference was and also because Paint Shop Pro was readjusting something to do with color every time I launched itn then set it back when I closed the program and I wanted to see what was going on. When I went back to 32 bit color, the resolution setting of 1680 x 1050 no longer fills the entire monitor screen as it had before I screwed with things. I've looked all through the settings, even reset the factory settings on the monitor to try and get a full screen back but I can't. I only get a full screen now when I go to 1920 x 1200, which I don't want. Any idea what I could have done or how to fix it? Thanks.
