DisplayFusion folks,
I've been battling an issue with my workstation and DisplayFusion recently. I've got a Quadro K620 card and a pair of Acer K272HUL monitors running in DisplayPort 1.2, daisy chained off the DP port on the GFX Card. OS is Windows 8.1, DisplayFusion versions vary but currently 8.1.2. NVidia Driver version 353.06. I've tried forcing the EDID, but it won't let me apply it to the DP Port.

Every once in a while, after the computer puts the monitors to sleep (windows turns off the monitors after 60 minutes), they will not wake up at all. I can move the mouse, Alt-Tab, etc, but nothing brings either monitor back. The instant I hit the power button, the primary monitor wakes up and shows the "Shutting down" animation. When the PC boots back up, all my windows are jammed into the left upper corner, indicating that the resolution got stuck at something around 800x600 or 1024x768.

The behavior is completely intermittent, sometimes just moving the mouse will wake up the monitors, sometimes it takes an Alt-Tab or windows key press. Other times, it's just stuck. Sometimes it happens on the first sleep after a reboot, sometimes it'll go a few weeks without doing it at all.

I've attached my latest DisplayFusion settings backups and troubleshooting log (L0). I do have DisplayFusion running a blank screensaver after 15 minutes, and that doesn't match the Windows sleep settings. Dunno if that's a cause, as I haven't tried changing those settings.

Any help is greatly appreciated.

I'll try that. I also disabled the Windows sleep monitors after 60 minutes setting. If that doesn't fix it, I'll re-enable it and turn off the DF screensaver.

Thanks.

Nope, disabling the windows screen sleep didn't help. I'll disable the DF Screensaver.

Turning off the DF screen saver, and letting Windows run a blank screensaver after 15 minutes seems to have taken care of the problem. Thanks!
