2 monitor issue with nuc10i5fnh

[DrZoidberg]

Trying to connect 2 monitors to my NUC, one via USB-C (DP1.2) the other via HDMI 2.0b.

Both Monitors are AOC cu34g2x, so should be no issues there.

Problem as follows, i can run both Monitors in isolation, but as soon as i connect the 2nd, either by HDMI or DP the 2nd Monitor will not be detected.

For absolute clarity i'm trying to connect as per the first 2 display option example in the link

https://www.intel.com/content/www/us/en/support/articles/000056438/intel-nuc.html

All my drivers are up to date

I can run both monitors at the same time if i connect 1 directly to HDMI and the other from the Monitor HDMI via a HDMI to USB C lead into the NUC TB3, 

HELP

Hello DrZoidberg,  

Thank you for posting on the Intel® communities. I want to understand what happened just as much as you do and to proceed further, I would like to confirm the following:

1. What is the BIOS version installed?

2. What is the graphics driver's version installed?

3. Did you test with different cables?

4. Have you performed any firmware updates to the monitors?

5. Just to confirm, the configuration only works if you use an adapter HDMI to USB-C?

Are you following the procedure to detect the second monitor?

2nd Monitor is not detectable when connected via USB-C to DP when 1st Monitor is connected by HDMI, but will 2nd Monitor will work when 1st Monitor is disconnected

Hello DrZoidberg, 

Thanks for the confirmation. I was checking your AOC cu34g2x specifications and noticed that it only includes 2xHDMI and 2xDisplay port, it does not mention Thunderbolt support for video. It mentions a "USB fast-charge port" that usually is USB-C only, but in this case for power and not for video support. 

• Monitor: https://aoc.com/us/gaming/products/monitors/cu34g2x/specification

I recommend you to get in contact with AOC to confirm this information and for advice. Please keep in mind that this thread will no longer be monitored by Intel.

@DeividA_Intel 

Not sure what your point is?

Intel own advice is to connect the Monitors as i am trying, see this link

https://www.intel.com/content/www/us/en/support/articles/000056438/intel-nuc.html

so connection from NUC to Monitor as follows

TB3/USB-C to Displayport 

Is absolutely fine, no need to contact AOC

And anyway the connection works fine for a single monitor, the problem is when the second is connected via HDMI to HDMI

Hello DrZoidberg, 

I do apologize for the misunderstanding. I would like to continue with the investigation and I will require the following reports.

1. Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system.  

• Download the Intel® SSU and save the application on your computer: https://www.intel.com/content/www/us/en/download/18377/intel-system-support-utility-for-windows.html  
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".  
• To save your scan, click Next and click Save.  

2. Provide the Report for Intel® Graphics Drivers with both monitors connected: 

• https://www.intel.com/content/www/us/en/support/articles/000005848/graphics.html

Hi @DeividA_Intel 

See attached reports, 

For some reason windows will not allow me to download and install Intel Graphics Control Panel?

[DeividA_Intel]

Hello DrZoidberg, 

Thanks for the information provided. I would like to let you know that for 6th Generation Intel® Core Processors and newer: The Intel® Graphics Control Panel has been discontinued from Microsoft and has been replaced with the Intel® Graphics Command Center.

Also, I will proceed to check the issue internally and post back soon with more details.

Hello DrZoidberg, 

Thanks for your patience. From your report, you are using Windows 11 Enterprise and this operating system is not listed as supported/compatible for this NUC. I recommend you to test with one of the supported operating systems (Windows 11, Windows 10) and then, make sure you have both Firmwares are up to date (thunderbolt and HDMI).

• Thunderbolt must have a Thunderbolt device connected: https://www.intel.com/content/www/us/en/download/19794/thunderbolt-3-firmware-update-tool-for-intel-nuc-10-performance-kits-mini-pcs-nuc10fn.html
• HDMI: https://www.intel.com/content/www/us/en/download/19639/intel-hdmi-firmware-update-tool-for-intel-nuc-10-performance-kits-mini-pcs-nuc10fn.html?

Hi @DeividA_Intel ,

Thanks

From my understanding Windows Enterprise is not missing anything that would cause these issues, its simply a more comprehensive edition, no NUC is listed as supported with Enterprise.

I have run both Thunderbolt and HDMI updates and the problem remains

[DeividA_Intel]

Hello DrZoidberg, 

I understand your concern. However, your NUC is compatible with 

Windows 11 and Windows 10, even though Windows 11 Enterprise is working with your NUC, it may encounter unexpected issues like this one.

If possible, try any of the supported operating systems to confirm if the issue persists.

Hi @DeividA_Intel 

Sorry if i have this wrong, are you suggesting i buy another copy of windows 11 or 10 to try with the NUC?

[DeividA_Intel]

Hello DrZoidberg, 

In this case, there is no need for you to buy a new license, you can test with a new install without a license just to make sure if this issue is related to the operating system or this NUC.

Thanks for your comprehension.

Apologies for my ignorance, how do i do that?

[DeividA_Intel]

Hello DrZoidberg, 

You can check this Microsoft forum where there are steps and recommendations on how to install Windows without a license. However, I recommend you to check with Microsoft to make sure you are following the right steps, you can mention that it is just for a test.
