NUC12 and 3 monitors

[christophe1]

I have connected 3 monitors, (2 HDMI, 1 USB-C) to my NUC12 device.  It only works until I reboot when only 2 monitors are active.  I tried changing cables, updating driver / bios etc to no avail.

This is the one thing that makes it work at least till the next reboot.

I go to the Intel Graphics command center, select Display, then the monitor that does not work , and toggle disable / enable.

It is very cumbersome to have to do that every time.   Is there a more permanent fix to this issue.

Thanks

Hello christophe1,

Thank you for posting on the Intel® communities.

I am sorry you are having issues with your Intel® NUC 12 Pro Kit NUC12WSKi7, I will be glad to assist you.

Please provide the following information:

• What is the model of the three monitors connected to the NUC?
• Is the issue happening always to the same monitor connected to the same port, or it varies?
• Did the issue start after any hardware change or driver/OS update?

As well, perform a clean installation of the latest graphics driver for your NUC 31.0.101.1999 (https://www.intel.com/content/www/us/en/download/739790/intel-graphics-dch-driver-for-windows-10-64-bit-and-windows-11-for-intel-nuc12ws-products.html)

Hi Steven, thank you for your reply.

Samsung U28E850

Always the same Display (U28E850) .  I have tried to use the USB-C / Thunderbird  and HDMI.  Same result

Nope

As well, perform a clean installation of the latest graphics driver for your NUC 31.0.101.1999 (https://www.intel.com/content/www/us/en/download/739790/intel-graphics-dch-driver-for-windows-10-64-...)

I did this during my initial install last week.

Many thanks for your detailed reply.

Please provide the following information:

On Windows, look for the Intel® Graphics Command Center > Go to Support > Click on System Diagnostic > Click on Generate report > Save the report as a .txt file and attach it to your reply.

• Download the Intel® SSU https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

The problem is back after a small power outage (the NUC12) was on a UPS though.

One of the monitors  (Lenovo T27p)  is not detected anymore .  The monitor is fine as I checked using the same cable with another PC.

If I go to the Intel Graphics command center, select Display,  unlike before, the LEnovo monitor does not appear there.

[christophe1]

SSU output.    Display section looks suspicious

[n_scott_pearson]

1. If you plug in just Monitor 1, does it work consistently?
2. If you unplug Monitor 1 and plug in Monitor 2 (in its connector, not Monitor 1's), does it work consistently?
3. If you unplug Monitor 2 and plug in Monitor 3 (in its connector, not Monitor 1's or Monitor 2's), does it work consistently?

If the answer to all three questions is not Yes, then there is/are adaptor/dongle/cable issue(s).

Just saying,

...S

Scott,

It is not a monitor or cable issue.  Each work fine individually.  Up to any 2 . but not 3.   It used to work fine, but now Monitor #3 is not even detected by the intel utility.
