NUC 34010WYB. Visual Bios setup is ok, but when it is time to boot Win7 both screens are blank. Both screens are getting video sync signals because their indicators are green instead of yellow. If I start again from power up with either monitor disconnected, Win7 will boot up just fine. I can then plug second monitor in and everything is ok. I just don't like having to unplug and plug a monitor in every time I power up.
Hello KB55, please check the following things:
Check your graphics driver version and make sure you are using the correct version from this page (64 or 32 bit)
Try different HDMI cables, if you can; be sure they are HDMI 1.4 cables.
If you are uisng any display adapter/dongle, try without.
