NUC8i5BEH Graphics issues with windows update driver.

[Forester]

Hi.
I'm having issues with my NUC8i5BEH connected to a Dell U2419H via a USB-C to Displayport cable.

I've recently reinstalled my NUC and Windows automatically installed its own driver when first booting to Windows...however, when this driver is installed the screen goes off and will not turn back on. Connecting to an HDMI TV works OK.

I have tried with other USB-C to displayport cables with the same result.

Additionally, when connected via HDMI with the Displayport still attached, the HDMI screen will constantly blink/flicker.

The annoying this is...I've tested the NUC on a different (borrowed) monitor connecting to DP and it works fine. My U2419H also seems to work fine on other PCs (various intel and nvidia GPUs)...

I've done a test install where I've installed Windows using a borrowed DP monitor, shut the NUC down after driver install, plugged my U2419H in and powered up...Display comes on for POST however when Windows driver loads, display turns off and does not come back.

So I'm not at all sure if it's
a) Faulty NUC.
b) Fault Monitor.
c) Incompatability between NUC and monitor.

Windows 10 version is 20H2 and NUC BIOS is 0087 (latest).
(I'd like to try earlier BIOS however the page for 0087 download says this version cannot be rolled back...)

Any thoughts?

Thanks

Hi @Forester 

1. Start with downloading and installing the Chipset Device Software and the Management Engine Driver. After installing both drivers, reboot your NUC.

2. Next download and install the Intel DCH Graphics Driver and reboot NUC.

Thanks for your reply.

I've tried those steps with the same results.

Hello Forester,  

Thank you for posting on the Intel® communities.   

In order to better assist you, please provide the following:  

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://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

· 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:

3. Have you updated the monitor's firmware? You may need to check with DELL.

4. Have you reinstalled the operating system?

5. Have you checked with DELL if there is any kind of incompatibility between the Nuc products and your monitor?

Hi, apologies for the delay in reply, i need to borrow an HDMI cable from somewhere to run SSU and the driver report Which isn't too easy at the moment

I've checked for monitor firmware updates and none are available for this monitor. I've also checked for compatability issues and can find no reports.

I should be able to get an HDMI cable again on monday...So I will update then. Thanks.
