HMDI not working on my NUC8I5BEK2.

The display is working with a USB-C/DisplayPort cable, but I need also the HDMI and the screen doesn't detect any signal when I choose this input, even during the initialization.

 

The screen and the HDMI cable does work and have been tested with a rasberry Pi.

SDaro, Thank you for posting in the Intel® Communities Support.

 

The HDMI port, was it working fine before?

 

Normally for this scenario, we recommend to test another HDMI cable and also to connect the Intel® NUC to a different monitor/TV to rule out a possible problem with those devices.

Since you mentioned that those components were tested and they are working fine what we can try is to do a BIOS update to the latest version, 0073:

Additionally, please install the latest Intel® Graphics driver for the Intel® NUC, version 25.20.100.6519:

Thanks for your reply. Here are few answer to your questions.

 

The HDMI port has never been working.

I'm using this on LINUX (debian/ubuntu) and as the HDMI is not working even during the BIOS initialization I think the problem is deeper.

I should try with a different monitor but unfortunately I don't have another.

 

The BIOS has been recently updated to BECFL357.86A.0071.

I will update to 0073 and give you the result.

The BIOS has been updated to 0073, without any improvement.

The usb-c/DisplayPort is working but the HDMI still gives "No signal".

The screen is an ASUS VE278Q.

SDaro, Thank you very much for letting us know that information and for providing those results.

 

Just to let you know, the Intel® NUC Kit NUC8i5BEK was validated by Intel® as fully compatible with Windows* 10, so all the drivers that we have available in our web site will work only with that Operating System:

https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html

 

You mentioned that when using the HDMI port not even the BIOS screen is showing, so as you said, it seems the problem is not related to the Operating System being used, it seems to be a hardware problem with the HDMI port, based on the fact that the USB-C/Display port is working fine and that we almost tried all the troubleshooting steps that we recommend for this scenario and the problem persists.

 

So, at this point, the next thing to do will be to get in contact directly with your local Intel® support department in order to replace the Intel® NUC, they will provide all the details about how the replacement process works:

Before returning the computer, I maybe would prefer trying further, because if it's a design problem or due to this specific monitor, I'll have the same problem after replacement.

What about this message suggesting that "It is a defect in circuit design (...) in my opinion, need more current for HDMI +5V bus"?

SDaro, thank you very much for your response.

 

Yes, sure, we can always try further troubleshooting steps, because as you mentioned, if it is a design problem you will have the same scenario with the replacement Intel® NUC.

 

In reference to that other thread, it is a different situation, that customer is working with an HDMI adapter/converter/switch, so the suggestion provided in there is related to when you use any of those components.

 

In this case, you are using a straight HDMI connection, so the next troubleshooting step to try will be to test the Intel® NUC with a different monitor/TV if you have the option of course.

 

There are no reports stating that there is a known issue with the HDMI port when using the Intel® NUC Kit NUC8i5BEK.

All right. I'll then looking for another HDMI device to test with, and I'll come back here with the results.

 SDaro, I just wanted to check if you were able to test the Intel® NUC with a different HDMI device and what were the results?

I just successfully did this morning with a beamer. The HDMI is working perfectly with this device, good news!

So the question remaining is why does the nuc fail to contact the ASUS monitor...

I'll welcome any suggestion to debug but you can also close the topic, as there is no evidence that the NUC is causing the problem here.

Thanks for your help!

SDaro, You are very welcome, thank you very much for letting us know those results.

 

It is great to hear that the HDMI port of the Intel® NUC Kit NUC8i5BEK is working properly with the beamer. As you mentioned, we can confirm now that there are no hardware issues wit the HMDI port in the Intel® NUC.

 

I looked in ASUS's web site for a possible firmware update of the monitor but I did not see that option:

https://www.asus.com/Monitors/VE278Q/HelpDesk/

 

Based on the fact that the monitor never worked with the Intel® NUC, it indicates that it might be a compatibility problem.

The HDMI version of the Intel® NUC is 2.0a:

https://ark.intel.com/content/www/us/en/ark/products/126147/intel-nuc-kit-nuc8i5bek.html

 

I looked for the monitor specifications and it does not show which HDMI version it supports:

https://www.asus.com/Monitors/VE278Q/specifications/

 

So, at this point, the next thing left to do will be to make sure that both, the cables and the monitor/TV support HDMI version 2.0a.

Hi, Indeed, I'll have no time now to investigate further but I have an important answer: my HDMI could work and no need for a second return. You can close the case. Thanks, Simon
