PC won't connect to a monitor/TV with a HDMI cable

[Wilhelmus]

Hi all,

I'm a bit desperate so I came here hoping to find some answers.

So I wanted to connect a second monitor (which is a TV screen) to my PC to watch movies, but suddenly my PC wont send any signal to my TV, so I tried connecting all kinds of HDMI cables to all kind of TVs/monitors laying around in the house, and my conclusion is that whenever I tried to connect a second monitor with HDMI directly to my PC it wont show anything and it also doesn't show up in my Display settings on my PC. So from what I can tell the problem lays with the PC itself (within windows probably).

I have up to date display drivers so that is not the problem.

Also something worth mentioning is that my main PC monitor is connected with DVI, and the DVI connector works just fine on every device.

Hope someone can help me find an answer soon!

Either:

 

1) The HDMI port is dead on the TV or computer.

2) Your PC doesn't support multiple monitors

Are you using your GPU or iGPU or both together?

[Moonzy]

is it connected to the motherboard or you have a gpu?

 

did you enable the other monitor in the windows display settings?

[LynxThe1st]

Some cpu's don't support amount/resolution/cable

 

ark.intel.com

go to your cpu and look at graphic specifications, should tell you

edit: but I doubt that's the problem, could be though

1.Try,  (windows + p) to change the output mode

2.maybe the cable is broken maby your computer is broken or doest support multi screen, but first try num.1

How do I know for sure that my HDMI port is dead? because whenever I connect a monitor the HDMI doesn't seem to give any signal.
And my PC does support multiple monitors, I've had 2 monitors for about 1 year, and now suddenly it stopped working.

I'm using a GPU (GTX 770), and both my DVI and HDMI cable are connected to it.

My second monitor (the one connected with HDMI) doesn't show up in the display settings on windows.

Tried Windows + P but doesn't seem to do anything, and I'm indeed beginning to think my HDMI port on my PC is indeed broken  (though I've never done much plugging and unplugging..)

it will be great if you had a friend that could help you out with testing your your cable with another device or if possible try another cable

if you're plugging into your monitor and have a dgpu, did you enable your igpu?

Nope, the igpu is disabled.

Well I just noticed that nothing works if I connect it with HDMI to my PC, so when I connect my TV alone it doesn't show anything, even when I try to connect my primary PC monitor with HDMI instead of DVI it doesn't show anything.

means the hdmi port is broken?

 

try re-installing the gpu drivers

uninstall using ddu and install the newest version if you're amd, install 361.xx or 362.xx if you're nvidia

Yeah so I guess my HDMI port on my graphics card is broken? Though I didn't do much plugging/unplugging with it, how does that even brake?

btw the drivers don't seem to be the problem, reinstalled them and updated them, still no luck.
 

Anyway I'll have to thank you guys for the fast replies and feedback!

Tried out an older nvidia driver, but still no luck, so my HDMI port must really be broken.

It's really strange how it worked just fine, until 2 days ago it stopped working.. and the only thing I changed was a new cable, but the cable works just fine on other devices, and the old cable I used also stopped working when connected to my PC.

possibly broken hdmi port `-`

[Wilhelmus]

So just to let everyone now, the problem has been solved.

The issue with my HDMI that couldn't connect was clearly a broken HDMI port on my graphics card. And now I bought myself a DVI to HDMI cable, and now it works just like it should.

Thanks a lot for your fast feedback everyone, it really helped. I will definitely come back to these Forums if I have some other issues with hardware/software (hopefully not).

Cheers!
