I have a dual monitor setup on my Windows XP. To replace a monitor, I moved everything to 1 monitor and checked it as the primary monitor and unchecked "extend my desktop" for both monitors. The second monitor went black - as expected. I replaced the monitor and now want to switch back to my dual monitor mode. However, when I right-click>properties, the display properties are not displaying on my primary monitor. How do I get them onto the viewing monitor if I can't see it?
