I've upgraded both my PC's to 8.1 and while HTPC went just fine I had a bit of headscratching to do on my main PC!
Simply it defaulted VGA output to switched off (not even on stand-by!!) HDMI TV so after reboot I was greeted with Windows 8 loading screen for few seconds and then BLANK black screen . I thankfully noticed HDD active light flashing so I knew it was doing something, but still waited for good 20 minutes before deciding to hard-reboot my PC. Second time it did exactly the same, so I ran Windows repair (refresh) which again fixed nothing. Only after that I started looking for some unusual possible causes of this issue and decided to try checking output on 2nd display. Plugged my TV to power socket, powered it on and bingo! I had picture!
How wired is that? I would understand if Windows decided to display picture on both screens in clone or extended mode, but on disconnected HDMI TV while leaving primary screen blank and not even off?? Crazy!
