Removing the Message “CHECK CABLE SIGNAL”

Thank you. The given links list various possible causes, including a malfunctioning graphics card, a bad cable, or some hardware problems.

However, my monitor, the graphics card, and the system unit work well. There no hardware problems. The “No Signal” message appears only when the computer is powered off. The monitor works when the computer is running. Previously, there was no “No Signal” message when the computer was not running.

Do you know what the cause of the “No Signal” message may be?

 

HDMI cable not detected by computer

I want to connect to a monitor or TV with HDMI. No signal to either. Monitor says "no signal coming from your computer".

I have tried with no success:

• HDMI directly into Nvidia 980 HDMI slot
  
• HDMI directly into motherboard slot, Intel i6700k with integrated graphics
  
• HDMI indirectly into HDMI(female)-to-Displayport(male) adapter, into Nvidia 980 Displayport slots
  

I have verified:

• Cable plugged into second computer, connected fine to monitor and TV
  
• Tried different HDMI cable, same results on both computers
  
• Displayport slots on Nvidia 980 work on monitor with DP-mDP cable
  
• Both monitor and TV are 4k. Output is 4k on other computer, and 4k using Displayport on this computer.
  
• Used newest graphics driver for Nvidia 980
  
• Used old graphics driver (2020) for Nvidia 980
  

All cases, other computer connected successfully and this computer received "no signal"

Other than the hardware checks and the driver checks, I am not sure what other steps I should try.

Since it applies to both Nvidia 980 and motherboard, and since Displayport works but HDMI through Displayport doesn't work, I feel like there is some issue in the computer working with HDMI signals.

Thanks, Ahmad
