Hi, monday of this week i purchased two new monitors (W2071D). I had to buy an adapter for the second monitor to hook it up to the computer. So one goes directly to vga, the other plugs into the vga adapter then goes to usb port. It was very simple just plug and play and everything worked great! The next day i fire up the computer and it was only on one monitor and the home screen changed form #1 monitor to #2. I was able to switch them back and extend the screen. The next day i come in turn on the computer and now it will only show on one monitor. Ive tried extending and it wont apply it will just switch to the other monitor and leave one blank, and i can get it to duplicate no problem. it just wont extend. My computer has a ATI Radeon 3000 Graphics card.
