Phantom Screen

I am currently running a system with a Win7 and a Radeon 5770 powercolor card hooked up via DVI to a 19 LCD. There is nothing connected to the VGA or HDMI ports.
Every time my system starts (or wakes up from sleep) my system detects a second screen, that does not exist. If I move my mouse all the way to the right, it disapears, as if there is a second screen there.
When I go to CCC i can disable the second screen, and that fixes the problem... until I restart or put my PC to sleep, which makes it very annoying.
Now this did not happe on my older 8800 GT, with the 5770 replaces, I have the latest drivers (10.7).

Anyone with a solution? I have tried reinstalling Win7, it did nothing, other than this, the 5770 has no other issues (gaming or otherwise).

  1. Maybe try disabling the "second" screen throug the display properties in Windows as WELL as CCC, and then apply/save both of them, and restart. Maybe that will help.
  2. nope, tried that already, i need to figure out why my pc is detecting the 2nd screen in the first place.
