Thanks Oviano for initiating this bug report. I can verify this is also an issue with the Intel NUC D34010WYK.
My usage scenario, probably somewhat common, is to use the device as a Windows HTPC in a headless configuration. Well, I'm totally blocked from doing so. Using either LogMeIn or SplashTop remote software, and I assume VNC and Remote Desktop too, the device seems to lock up when the HDMI cable is unplugged. I also believe this is an issue in booting without a monitor.
To reproduce, install some remote desktop software (LogMeIn, SplashTop, whatever) and yank out the HDMI cable, wait 10 to 30 seconds. The result is a black screen and a frozen mouse cursor. The expected behavior is for the remote desktop to continue to appear and be usable. I agree with Oviano that this is an EDID related issue. I know the graphics driver guy is going to slap his head when he hears this bug report.
I'm using Windows 8.1 Pro N with the latest BIOS, graphics drivers and all others.
