I have two monitors. I have been using them for years with a hd 5700 on win7.
A few weeks ago, the 2nd stopped working. It went black, "no signal". If I went to the Win7 display resolution/preferences, I could get it working again if I selected "duplicate displays", but it turned off as soon as I selected "extend display". This is the setting at which they've been working for a long time. One is HDME and one is DVI, btw.
So I downloaded Catalyst, and if I create an Eyefinity group, they will both work. The problem is, it's one extended display, and I want to be able to open browsers in each display without having to carefully manually scale them to that window. This is a PITA.
I assume it was a driver update, but I can't roll it back. I don't know if this is related to my autohide taskbar often not autohiding, but probably not. Thanks for any help.
