HDMI no signal after being turned off for a longer time on NUC6CAYH.

I have a NUC6CAYH which works fine except when being turned off or removed from power for a longer period (1 hr+). At the next restart the HDMI output doesn't provide an output signal to the monitor. Restarting the NUC after logging into windows fixes the problem. Any idea on how to fix this?

 

HW/SW details

OS: Windows 10 Home

NUC6CAYH with latest BIOS and HDMI firmware

Attached as instructed.

 

I have tried other cables. My monitor is the NEC MultiSync EA274WMi

 

I think this happened after I updated the bios, but I'm not certain.

Hello trader2002,

 

Thank you for your response.

 

Please perform the following steps and let us know if the problem persists:

 

  • Clean installation of graphics driver

1. Download the latest DCH driver for your unit

Download link: 26.20.100.7529

 

2. Disconnect from the Internet.

3. Uninstall any existing DCH Graphics driver via Start > Settings > Apps & Features.

4. Uninstall the (DCH) Intel® Graphics Control Panel via Start > Settings > Apps & Features.

5. Restart the computer.

6. In Device Manager > Right-click on "Intel® HD Graphics".

If "Microsoft Basic Display Adapter" is already listed skip to step#10.

 

7. Select "Uninstall device".

8. Enable the option "Delete the driver software for this device" and click "Uninstall".

9. Restart the computer.

This should delete any non-DCH driver stored on Windows driver repository. Repeat steps #6 through #9 until "Intel® HD Graphics" changes to "Microsoft Basic Display Adapter")

 

10. Install the DCH driver downloaded in step #1.

11. Restart the computer.

12. Reconnect to the Internet.

13. Restart the computer.

 

  • Try to update the monitor driver and/or firmware.
  • Check the power options of the monitor.
  • If possible, try to use another display/TV.

Thank you for your reply. This isn't an Intel Graphics driver issue. Not even the splash screen will show and Linux will have the same problem. Note that, as I have mentioned, restarting the NUC after windows login will fix this problem. It also doesn't seem to be the monitor. I have no such issues with other computers.

Hello trader2002,

 

Thank you for your response.

 

  • Do you remember when this issue started happening? (BIOS update or driver update)

 

  • Were you able to check or update the monitor driver and/or firmware? This is important because some devices may require a newer driver/firmware update to work with other devices.

 

  • Are you able to test another monitor/TV?
  • Are you dual booting Linux and Windows*?

 

  • We recommend that you load BIOS default settings in case any changes were made in BIOS.
  1. Press F2 during boot to enter BIOS Setup.
  2. Press F9 to set defaults.
  3. Press F10 to save and exit BIOS.

Yes, however resetting the BIOS had no effect. At the moment I'm only running Windows. Haven't been able to try a different monitor.
