Default Weird problem that I cant find a solution to.

The setup is 2 monitors and a TV. Everything is running off of the main board (integrated video). The TV is connected via HDMI and is monitor 1. The dual displays are both HP L2206tm. Monitor 2 (main screen) is connected via VGA and Monitor 2 is connected to the Kensington USB3.0 Adapter.

Settings are TV on top in line with main screen (monitor 2) and monitor 3 is to the right lined up with 2. Resolution and all of that is identical on the two HP's. The left shows #2 and the TV shows #1 when I click identify. #3 doesn't show a number at all and this is where things get weird.

#3's wallpaper mirrors #2's (I have it set to extend). I can move my mouse over to #3 with no problem. However, nothing else will display on 3. If I drag a window over it will disappear like it's going to 3 but it won't display.

I've reinstalled the drivers and switched the cables and the problem then reverses. I'm at my wits end on this. Any ideas?

Hello, weird indeed.
Have you tried forcing a monitor rediscovery by deleting the persistence registry keys?

It would be interesting to know what graphics drivers you use, on which OS, which which DL drivers.
