This happen to me also on the NUC5i7 version but it was with Windows 10 Pro. Disconnect and Reboot brought it back(nothing else did).
I have since removed Win10 as it did something that did not seem normal(to be fair I think its the OS not the NUC), like desktop background would disappear and the only way to bring it back was restart explorer. Also I was still getting output from the Displayport as I have dual monitors. It has not happened on the Windows7 64bit install.
Thanks for the reply. Since I've got it working on my other nuc with the
same windows 7. I'm thinking it might be this NUC. I have also rebooted
as will as reloaded the drivers. I am going to do a complete w7 install
tomorrow but thats a pita It takes me about two days to get all Win updates
and the other OS system stuff going. I really don't run but a hand full of
programs so that only takes me about a day. Thanks again roger
You are getting random issues with the video at startup. Please give me more information about the problem and your system configuration. Are you using dual display? Let me know the current BIOS version, chipset and Management Engine drivers. Do you have straight video cables?
Did a Clinton wipe of hard drive and fresh W7 install. I now have HDMI but lost by USB display. I installed display link and it looked like all went well. Plugged in the usb display and nothing. I get popup that says somthing like my driver is newer and to check for update of display link. I have the latest. This was working before I started messing around with the hdmi. I loaded the latest Intel HDGraphics driver and that when I lost the usb display. On my other NUC I have HD Graphics 3/16/2015 10.18.14.4170 driver. The USB display works on that machine. Where can I get. that old driver? I looked on the nuc download page and found one 6/29/2015. But nothing going back to March. The 6/29 one also did not work.
It is recommended to use straight connections with high quality cables to ensure best performance. The use of kvm switches, usb display adapters, and VGA/DVI/HDMI Adapters is possible, however, we could not guarantee its functionality on all the cases.
You could try cloning the Operating System image as c0op3r suggested. Additionally, you could check the Graphics driver installed on the other NUC you mentioned was working fine and downgrade your current one to that version.
