Windows 10: PC mintors detect cable but to signal! Please help!

I had bought a new desk so I had to unplug and move all my stuff, before everything worked fine. Now that everything is redone the exact way it was before, neither of my monitors show a signal. PC turns on fine but neither monitor works, I’ve tried 3 different hdmi cables, 2 different display port cables, and neither monitor has a signal. When they go into sleep mode and I unplug or plug into the PC they wake up but no signal. So it seems lile they detect the cable but dont show a signal. I also tried cleaning RAM cards, clearing all dust, all connections secure. Any suggestions? Thank you!

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

 

HDTV inconsistantly detecting hdmi signal from PC

Hi,

I recently purchased a new Dell XPS desktop. I connected the desktop through hdmi output to my 3 year old 1080p LG tv. The connection was successful, The TV detected the PC, and I successfully set up my windows 10 PC. However, after powering off the PC
and then booting again several times (normal use of PC), the detection has become inconsistent, for example the Dell logo is no longer appearing, the TV screen now just slowly detect the signal from the PC and after some wait with black screen it shows the
lock screen. After the lock screen appears, I log in to my PC and the PC works just fine. Could this be due to the hdmi cable, the reason for this guess is first, I am using for this connection an old hdmi cable that was purchased with a Samsung tv monitor
about 6 years ago. And secondly, I have a Roku box connected to my LG tv that gets detected with it's own hdmi cable just fine, I also owned a xbox one console (I no longer own), this video game console was connected to my LG tv also with it's own hdmi cable,
and the tv detected the signal perfectly when signing in. I am hoping that this problem will not escalate into the tv not detecting the signal completely from the PC and possibly damaging my new desktop. Thank You
