When I plug in or unplug my external display to my laptop, my display options no longer automatically reconfigure as they used to do. Now if I unplug the monitor, Windows acts as if it's still there, and windows that were on the monitor stay offscreen (as does the cursor, if that's where it was). I can manually move the cursor back, right-click load graphics properties and make changes OR do an F-key combo to move everything back on the laptop screen OR program a hotkey but these are all pretty annoying for one reason or another.
Any ideas about the cause? Unfortunately this must have started happening sometime in the last two weeks--at the same time as I made a load of major computer changes. However this did NOT include a graphics driver change (my graphics driver is current). At this point I feel it could be anything, but I'm wondering if it could be a recent BIOS update I did that HP recommended.
By way of troubleshooting I did run Windows in safe mode with ONLY the "ATI Catalyst" and "AMD External Events utility" running on top of the basic services, in case a newly installed service was stealing hotplugging messages, but that didn't do anything. I've also gone exhaustively through my graphics driver settings to make sure everything there looks correct. No luck. Any ideas?
