Windows 10: I am trying to connect my laptop via HDMI / HDMI cable to my desktop monitor.

I am trying to connect my laptop via HDMI to HDMI cable to my desktop monitor. It worked fine until a week ago and then it suddenly stopped. The same is the case for my wife and my duaghters laptops, all of them to different screens so I doubt it's a cable problem.

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

 

Cannot connect HDMI Monitor with laptop

Hi!

Thanks so much for your response, Carmack!

I figure out the issue and want to share it with others. I used a USB - HDMI adapter and HDMI - HDMI cable to connect my laptop with the monitor. I removed the adapter driver (my laptop's functions are irregular when the driver exists). Now, I use a miniDP - DP cable to connect to the monitor. The problem is solved.

 

USB to HDMI adapter

1. Does your laptop feature a micro-HDMI port?
2. If so, are you wanting to connect an external monitor to the laptop?
3. And does the monitor itself use an HDMI connection?

If yes to all three you could try this cable... High Speed HDMI to Micro HDMI Cable (Micro HDMI to HDMI).

I use it for my 2013 Asus notebook when I want to connect to my 24 inch NEC monitor. The laptop has the micro-HDMI port and the monitor uses a full HDMI port.

Also, since my monitor supports PIP (Picture In Picture) I don't have to disconnect it from the desktop since it also supports multiple inputs - DisplayPort connected to my desktop, HDMI to laptop. The down side is the laptop screen size is small on PIP mode.

Anyway, if yes to all 3 above, that cable will work and it's only $11 dollars for a two pack. And Cable Matters makes good cables so nothing cheap.

Hope this helps.
