I'm using 4 monitors on a FirePro V7900.

I have selected, under Display Detection Option in the Catalyst Pro Control Center, "Use manual detection only (I must click the Detect Displays button)"

However, when I turn off a monitor, it still detects that the display has been powered off and adjusts my desktop configuration on the remaining displays.  I don't want that to happen, I want it to just keep displaying out that port, even if the monitor is off.


Graphics Card
- FirePro V7900SDI

AMD Catalyst Driver Version, and Driver History

- Catalyst Pro Control Center Version  2012.0902.813.12725

Operating System
- Windows 7 Professional 64-bit
- include details about additional operating systems also tested

Issue Details
- 4 Monitors, connected via Display Port connections.   Turn one off and the system detects it, even though I have selected Use manual detection only.

Motherboard or System Make & Model
- HP Z800

Display Device(s) and Connection(s) Used
The monitor that causes the detection of the powered-down display is a Dell U2410.  Connected via DisplayPort.

I'm desperately seeeking a solution to this problem, too! 

Specifically, my problem is from switching out a monitor via a KVM (as opposed to physically switching it off) but the problem is the same:  I just want ATI and Windows 7 to LEAVE MY DISPLAY CONFIGURATION ALONE until I tell it otherwise.

Does anyone have any more info on this problem?

I am also experiencing the same issue. "Use manual detection only" is selected, however when I turn off the monitor Windows makes the "you have disconencted a device" sound. Then when I turn the monitor back on Windows makes the "you have connected a device" sound and all the windows have been resized and icons moved.

Running Windows 7 64bit SP1 and AMD Catalyst revision 13.4 with AMD Radeon HD7870 connected via DisplayPort to a Dell U2713H.

It's an old setting surviving the win95 era. It was used to detect VGA monitors, old CRT TVs and stuff like that. These new displays are plug-and-play, it's the OS detecting when you turn it off, not CCC.
