NUC10 does not wake Displayport connected monitor

TonyC

I have 2 displays connected to my NUC10I7FNH4.

The main display is connected via Displayport and the secondary display is connect via HDMI.

The NUC is always on and the displays turn off after an hour of inactivity.

 

When I go to wake the displays only the HDMI connected display wakes. To wake the Displayport connected display I need to disconnect and reconnect the Displayport cable from the back of the NUC.

 

Is someone able to please help me fix this so the Displayport wakes my display?

 

Thanks in advance.

Hello @TonyC

Thank you for posting on the Intel® communities.


In order to check this further, could you please provide us with the following details?

1- Is this a new system? Did the computer work fine before or are you experiencing this behavior since the first day that you have the device?

2- If this worked fine before at any moment, were there any recent hardware or software changes that might relate to the point when the behavior started? (For instance, Windows*, driver, BIOS, or software updates?)

3- Are you using straight-through connections with a single cable to connect the computer and the monitors? One monitor HDMI-to-HDM, and the other monitor DisplayPort connected to the USB-C port (DisplayPort) in the back panel of NUC. Is this your configuration?

Or are you using any type of video adapters, converters, dockings, or extenders/extension cables? Please provide details.

4- Maker and specific models of the DisplayPort (DP) monitor and HDMI* monitor:


5- 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
  • 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.
  • Once you have saved the file (.txt file), please attach it to your reply.

To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.

Hi @AndrewG_Intel 

 

Thanks for the reply.

 

1 - The system is about a year old and it has been working fine. A little less than a year ago I had an issue with video playback and this was resolved by turning off browser hardware acceleration. screen flicker - NUC10i7FNB 

2 - The only change has been that I have attached a second display. My primary display was connected via HDMI. Now my primary display is connected via Displayport and a secondary display is connected via HDMI.

3 - I am using single cable straight-through connections without using any adapters. This is the Displayport I am using. https://www.amazon.com.au/gp/product/B00X8ZB6PM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

4 - The Displayport display is a Dell UltraSharp 49 Monitor U4919DW running at 5120 x 1440 resolution. The HDMI display is a Samsung SyncMaster S23B550 running at 1920 x 1080 resolution. (The HDMI display wakes fine)

 

Intel® SSU output file attached.

 

Cheers

Tony

Hello TonyC

Thank you for your response.


Could you please try the following steps and provide us with the outcome:

1- Test with a different DisplayPort video cable which was working before. Also, could you please test the NUC with another system? Is the behavior different? Or could you please test the monitor on another computer?

2- Check if there are drivers or firmware available for your monitor (.inf files) to make sure the software for your monitor is properly installed and up to date.

3- Is the behavior different if you try different (e.g.: lower) video resolutions or refresh rates for the DisplayPort™ monitor?

4- Please access the BIOS by pressing F2 during boot to enter BIOS Setup. Go to Advance > Video and test by changing the order of IGD Primary Video Port and IGD Secondary Video Port and test the behavior. Press F10 to save and exit BIOS Setup.

5- Make sure you have the latest Windows updates and install any pending updates.

6- Install the latest graphics driver for your Intel NUC, available on Download Center: Intel® Graphics DCH Driver for Intel® NUC Version 30.0.101.1191.

7- If the issue persists, could you please test the NUC using only the DisplayPort* monitor (no HDMI* monitor connected to the NUC) and test if the behavior is the same?
