I have no means of measuring the signal the PC is putting out but what you are suggesting seems illogical - possible but illogical!Only if you can verify that it is using the same frequencies and resolution across all three modes.
That is the issue - it is sending it. But because it is in a format the projector cannot display, it goes all black.
If you were to start playing with the resolutions on your laptop's screens, and were to pick something the screen cannot handle, it would do the exact same thing - turn black.
The screen is normally set at something the projector cannot handle (1920x1080) but the automatic conversion works just fine and the projector is actually sent XGA1 (or so the projector says) 1024x768 V Freq 60.00
So I set the PC to 1024x768 Freq 60.01 and still nothing changes - duplicate will not work and everything else is fine.
I think this goes into the too difficult bucket and I'll have to get a projector with HDMI input (when everything - including duplicate - works fine even though the PC is set at resolutions the projector can't handle)
thanks for your help and perseverance
