The problem I have is that periodically I lose the video output on the HMDI port and all I get is a blinking blue screen. This happens if I start up the PC with the HDMI switch not set to connect the PC to the projector, i.e. the PC doesn't see a monitor connected to the HDMI port. Understandable I guess, no EDID. However, there is no easy way I can get the PC to reactivate the HDMI port once this happens. I either have to restart the PC (which takes ages) or go to another machine on the network and VNC in to reactivate the HDMI port.
What I really need is some way of reactivating the HDMI port with a key press or whatever while I am looking at a blank screen.
Disconnecting and reconnecting the HDMI cable doesn't do it. I also tried this program which disconnects and reconnects the display:
I know about the DVI Detective solution but to use this I would need to buy a DVI detective and cables to swap between HDMI & DVI and back.
Has anyone got any ideas on how I can overcome this problem?
