I used to have a ATI 4850 card and have resently upgraded to a 7800 series.

I uninstalled CCC and reinstalled the latest version (Win 8.1 64 bit)

When I wake a PC I hear a sound (the same sound you get when you unplug a USB drive)  and then only one of my 2 monitors is working.

 

I then have to go to display properties and select detect after which the second monitor starts working. 

 

This happens about 50% of the time when waking up from sleep.

 

Any ideas  what is cusing this? I didnt have any problem with the 4850.

I've never had this problem try updating all drivers and take out your GPU and then put it back in. Let me know if any of this helps

I have two computers each with the same HD7900 video card running dual monitors.  One of the computers almost always loses the 2nd monitor on sleep.  The second loses the 2nd monitor about 20% of the time.  Very frustrating where rebooting is the only solution.

This only began last summer - I've had these configurations for a couple of years.
