When I first booted my new NUC5i7RYH a couple of weeks ago, I got no video output from either mini DP or HDMI into my Dell monitor. (I did not try VGA output). After searching around a bit, I found that updating to the latest BIOS (v 0348) cured the problem. The BIOS that shipped with my NUC was at least 3 revisions old. I had to remove the BIOS configuration jumper and reboot, and when the POST screen appears, press F7. You need to have a USB thumb drive plugged in with the latest .bin file (BIOS) at the root level. The rest is menu driven. After updating BIOS, replace the jumper and reboot. I hope that cures your problem, but I can't make any guarantees. Good luck. I know how disappointing it is to get a blank screen from brand new NUC!
I don't understand, you say you got no video at all, but then you say
> and when the POST screen appears, press F7
Are you saying removing the configuration jumper magically made video appear?
Or that you just had the USB stick with the .bin file on it already plugged in and just
pressed F7 blind? But then how did you "navigate the menus" blind?
Please give me more details on the process.
I'm still looking for an answer to my original question though, are both DP and
HDMI enabled for output by default?
Yes, DP and HDMI are enabled by default. Try connecting directly from the mini DP or mini HDMI output of the NUC directly to DP or HDMI input of a computer monitor. If you still see no video, try the BIOS update. And yes, removing the BIOS configuration jumper forces the POST screen to appear with various options. Have the USB drive plugged in with bin file and choose F7. You will see the BIOS update progress on-screen. The process is described here:
I don't have a DP monitor or a mini-HDMI to HDMI cable or I would have already tried
that (I still suspect the adapter, I can't believe Intel would ship a product that arrives
with no video output). So I was looking for a workaround to avoid buying a mini-HDMI
cable because I still want to eventually use the VGA route if possible.
So I will try removing the jumper and see if I can get something that way. I will report
back on my findings.
The type of adapter that you are trying to use may not respond correctly because the conversion from digital (mini-DP) to analog (VGA) makes the signal to go weak from the source (NUC) to the target (monitor), which may cause no video issues. We always recommend to use straight connections from the device to the monitor, like you did using a mini-HDMI to HDMI cable, which made you confirm that the NUC responds fine. Now, you can also test with a mini-DP to DP cable (with a monitor that has DP support as well) and confirm if the DP port is working properly. Also you may consider getting an active mini-DP to VGA converter, which may be able to handle the signal in a better way and resolve the issue. The BIOS update suggestion is more applicable to digital solutions like the usage of HDMI or DP only, so that is the reason why even with the BIOS update you kept having the problem.
If you have more questions please let me know.
