Hi buddy,
I am trying to reproduce your scenario.
My environment is:
Host: Windows 7x64
Guest: Windows 7x64 client named "Win7x64_1159255"
My Steps:
1, Launch Workstation and power on the guest "Win7x64_1159255"
2, Enter fullscreen mode
3, Enter 3 monitor topology with multiple monitor menu. I can see Windows 7 guest displayed on the 3 monitors correctly.
4, Wait 2 minutes till guest to be inactive. (I change power option. Setting turnning off display to 1minute and sleep after 2 minutes ) This time guest turns to be black screen and only display on the primary monitor.
4.1 , was the VM suspended after being inactive status ? In my scenario, it was suspended. So I have to resume the guest first ( I should say it took more time than I expected ) and then enter the credentials. Could you please confirm that ?
5, Wake up the guest and enter the credential. The display is in fullscreen mode but only on the primary monitor.(this seems to be a little differnt with you)
Could you please provide more detailed steps so that I can duplicate your issue ?
Thank you.
