Is active display cable recommended for USB-C to Displayport connections (32 inch monitor) with NUC?

I have a NUC 8 (8i5BEH tall) which uses the Iris Plus 655 GPU chipset for graphics.   I have it connected to my 32" Samsung monitor via a USB-C to DisplayPort cable.

I'm noticing that the monitor goes black and flickers occassionally, making it seem as if it's trying to resyncing its signal with the NUC's GPU. 

Is it generally recommended to use an active display cable, versus a passive non-active cable, when connecting large DisplayPort monitors to the USB-C connection on the NUC 8?

Good question! It's a possibility that might help; one I haven't tried. Has anyone?

BTW, display size makes absolutely no difference. It is resolution and frequency that matter.

Yes I tried using an Active USB-C to DisplayPort cable and I still get intermittent "blackouts" between the NUC and my Samsung 32" monitor, and I don't know why.   It's like the connection signal breaks and the has to be re-established.

Hello OneTech,


Thank you for the information.


Please follow the next recommendations and let us know the outcome:


  • Update the display's firmware: if available check with the display or television manufacturer's support website to see if there are any firmware updates available for the display.
  • Test different display resolutions: Determine if there are any specific resolutions that show the flickering. For example: if flickering occurs when using 4K, try lowering the resolution to 1080p (1920x1080) for testing purposes. Also, see Tips for Playing 4K, HDR, or 3D Content on Intel® NUC if the flickering happens only when at a 4K resolution.
  • Test different refresh rates: If the refresh rate isn’t optimal or is too low, flickering, lagging or other issues can occur.
  • Check display cables recommendations:
  1. Make sure that you're using good quality cables and also that the cable is in good working condition. Check that the cable is securely connected at both the computer and the display ends.
  2. Use cables no longer than 6.5 feet or 2mts to ensure signal integrity.
  3. Avoid cable adaptersFlickering display when using video adapters or converters, like the following:
  • USB-C to VGA
  • USB-C to HDMI
  • HDMI to DVI
  • HDMI to VGA
  • Recommendations:
  1. Don't use an adapter or converter.
  2. Purchase a cable to connect directly from the Intel NUC to the display. 
  • Try a different display: It's always possible that the display itself has gone bad. If possible:
  1. Try the flickering display with a known good computer.
  2. Try connecting a different display to the Intel NUC. 
  • Check for workarounds with the display manufacturer: Check with the display or television manufacturer's support knowledge base to see if there are known issues. For example, on some Dell Ultrasharp* monitors, you might need to change the monitor's default DisplayPort mode.


Let us know the outcome to verify if the issue persists with a different display and other details.
