Based on your description I would the problem is the video adapter you are using. We have received many reports from customers and I personally have tested one adapter like this (HDMI-VGA) and it did not work at all.
The reason of this is that the HDMI sends digital signals and the VGA adapter can handle Analog signals only. We do not recommend using adapters but if you would like to try again perhaps an active video converter can do the trick.
Thanks Kevin. I have a mini-HDMI to HDMI cable on order now so I can try it with my HDMI monitor. Fingers crossed.
Today I received a bona fide mini-HDMI to regular HDMI cable and attached to my ASUS VW246H monitor. Unfortunately nothing's changed. The system still behaves as if it's working, but just no video signal at all.
Is there a way to "factory reset" the NUC so that it goes back to the state it was in when I first did see video, the first time I turned it on? My guess is that it's got some video setting set that won't let it rediscover the current monitor and until I clear it I'm screwed. Note I did try cycling the monitor inputs using the button on it for that, no luck. It keeps saying "no video signal".
Try the steps mentioned here:
I think if issue persists, you should contact our support phone team for them to help you with a possible replacement:
I need this for the RealSense contest and the deadline for that is February 15th. I'm a finalist in the Ambassador lane. To wait for a product replacement would really hurt. Isn't there some kind of "hold this down while booting up",etc. kind of step I can take to reset the unit?
I really believe it's intact. For example, although I can't see anything, if I press the STANDBY key on my keyboard it does go into standby. I can see a brief disk write and then the power light flashes as it should in standby mode. Then if I tap any key the power light stops flashing and there's another brief pulse of disk activity as the system comes back online. I can repeat this as many times as I like and it always works.
Is there a short list of monitors that are absolutely known to work with the NUC? I'd be willing to buy one just to see, so the less expensive the better. If you know of a reasonably priced one that definitely works, please give me the manufacturer/model and what connector I should use (HDMI, DPI, USB, etc.).
I solved the problem and I'm leaving my findings here for others who experience the same problem.
- I had to give up on the micro to regular HDMI cable. During my web searching I believe I read that LCD monitors don't have the necessary signal converters to use HDMI directly like an HDMI TV can. I wish I could find the reference so I may be incorrect on this. But in any case, HDMI to my PC compatible LCD monitor was a complete failure for me.
- To solve it, I got an Display Port to DVI cable. I simply plugged the Display Port end into the NUC and the DVI end into my LCD monitor and it worked great the first time and every time after that.
NOTE. THE FOLLOWING IS SHEER SPECULATION:
The only thing I can figure is that the very first time I turned on the NUC the BIOS or some other persistent setting was in a state that had it put out a signal that worked with the original VGA output adapter I tried at the very start. Once it rebooted and something got saved, that path never worked again. So the moral is, to get the NUC working with an LCD monitor the safest path is to use the Display Port connected to an LCD monitor's DVI input. Fortunately the d54250WYKH NUC like mine has a headphone out jack so unlike other older NUC's I still can get sound output easily.
