i use this section in my conf file for nvidia, which solves it:
Section
"Device"    Identifier     "Card0"    Driver         "nvidia"    Vendor
Name     "NVIDIA
Corporation"    Option         "ConnectedMonitor"   "DFP-
2"    EndSection
get the actual monitor from Xorg.0.log file to put with 'connected
monitor' command. that's what worked for me
