Win7 open as if I had a dual screen setup - I only have 1

When win 7 open up, what I see on my single display is a desktop screen of a tipical secondary display that would be placed on the right of the main screen.

I go into desktop properties and I see that win7 detect and show 2 screens as if I had a dual screen setup. But I only have one 24" screen.

I always need to ask win7 to "detect" the screens again, then it automaticly delete the second "non-existent" screen.

My setup is Dell Sudio XPS 9100
I7 930
5870 geforce
12go ram
win7

Download the newest graphics driver from AMD for your graphics card and manage your screen using CCC.

You go to CCC to set the screen settings. Don't use Window's.

Did you install AMD Hydravision?

Uninstall it if you have.

I don't see Hydravision nowhere...

The second "virtual" display always comes back at each restart. It says CRT display. Then I ask the system or CCC to detect, then it goes away...

Here u go.

It was on "manual detection". I'll try it the other way...)

I'm actualy unsure if CCC start at startup . I don't see any entry in msconfig...

Yep, re-install CCC again.

Remove it first!

Remove every part of a program completely. And than install again.

The Windows uninstaller will not remove everything.

U can use Your Uninstaller! or Revo Uninstaller.

I removed CCC and all it's components and did a fresh install - it does the same thing when I boot - but this time, it stays on my main windows screen while there's a "virtual" right hand screen that you can point the mouse to whitout seeing it... kind of anoying because the cursor always disapear on the right side... Or when you want to press the X to close a program, you always loose the cursor on the right which is getting on my nerves....

I could... but I won't, since it's been like that for a while...
