No audio from TV connected to computer via HDMI cable

Hi Jim,

For us to further assist your with the audio issue on your TV when connected to the computer, please provide the following information below:

• Have you tried to update your audio and video drivers on the computer?
• Have you checked your TV settings if your HDMI settings are set up according to which port the HDMI cable is connected? For example: HDMI 1 or HDMI 2.
• Is the HDMI cable working if you use it on a different device?

Keep us posted.

 

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

 

PC and TV not connecting via HDMI cable

If the PC has detected your HDMI-TV connection then it will be shown as an additional display in Settings, System, Display.




If there is no additional display shown then your PC has not detected your HDMI-TV connection
- Unless there is something wrong with the connection itself, I'd first try going to your PC maker then downloading and [re-]installing the latest display driver.
- I suggest you also check your PC manual & any user forum your PC maker provides to see if there is any useful guidance there.
- You might also get somebody else to connect their PC to your TV using the same TV settings & HDMI cable to prove that nothing there is at fault.
