I am hoping that the wise people of MPC may be able to tell me if there is a software solution to this problem (I searched the forums here but did not find this ever being address here). I will summarize the issue below, but a good thread of angst (and a description of this 4 year old issue) can be found here: http://social.technet.microsoft.com/Forums/windows/en-us/8a9b5aa7-fe33-4e6d-b39b-8ac80a21fdc2/disable-monitor-off-detection-how?forum=w7itprogeneralSummary of the Issue:
When connecting two monitors using DisplayPort (with and extended view) if the second monitor
is turned off (powered off) the contents of the second monitor
are pushed onto the primary display
. This means that any work on the second monitor
is pushed to the primary display
. In addition, if both monitors are turned off, AND a remote control program is used (e.g. TeamViewer9), then the "layout" of dual monitor arrangement of the PC is entirely disabled and sent as a single desktop with a generic VGA signal. If DVI connections are used, the behavior described above does not exist.
In short, under Windows 7 and 8, 8.1, the DisplayPort is treated like a USB that has been unplugged (when turned off), instead of a device linked to the PCs display parameters. Thus, it is "redetected" every time the monitor is powered off.Why Should You Care?
New monitors are already ditching the VGA and DVI connections. This same issue has been reported with HDMI cables. I recently bought two awesome displays (both without DVI-Dell UltraSharp U2414H) and I cannot use the dual DisplayPort connection on my Gigabyte ATI 7870. Luckily using the DVI with and HDMI adapter and the HDMI cable does not cause the above issue so I have a workaround (although I think DP produces better control over the monitor's adjustments). In the future high end cards and monitors will likely eliminate DVI as well, thus making multiple monitor set -ups annoying instead of liberating if a software solution to the issue is not produced.
Any thoughts or insights would be welcomed.
P.S. THIS IS NOT A DRIVER ISSUE OR A HARDWARE ISSUE-IT IS A MICROSOFT ISSUE.
