Sometimes you see a red and green light. This could be due to loose cables connected to your GPU card to the PC HDMI port.

Another reason why HDMI ports fail to detect secondary monitor devices like HD TV or LCD TV, is due to faulty drivers of the GPU.

Some of the GPU cards which are having problem while updating from Windows 7 to 10 or older version like Anniversary Update are –

AMD ATI Radeon HD 4200
ATI Mobility Radeon HD 5000
AMD Mobility Radeon HD 5470
Dell Studio XPS 8100 with AMD Radeon HD 7570 graphics card
Toshiba L500-1ZP (2010) with ATI Mobility Radeon HD 5165

How to Test if PC HDMI Port is Working or Not?

There is no specialized equipment like multi-meter or signal tester to test whether the HDMI port is working or not. The best way is always to use the following.

1. PC or laptop with HDMI port.
2. HDMI cable
3. Monitor or HD TV or LED TV.

Out of all these, make sure the last two are working properly. Then you can test if the problem is with your PC HDMI port.

There are many different ways in which you can connect your PC HDMI to your monitor device.

For example, HDMI to VGA Adapter, a VGA cable, and a monitor with VGA connection. This is one of the old methods.

Similarly you can use a DVD adapter and DVI cable etc. But to be more sure use the above configuration.

Now if you get a signal on your display device, it means your PC HDMI port is working.

But if you get “No Signal or blank or handshake and then no signal“, something is wrong with the PC HDMI port.

Sometimes, your HDMI port may be working but no audio or video signal. Then you have to check through the Device Manager, whether that particular device is being displayed or not.

For example, if audio is not coming, then using the Sound item of Control Panel, you can check it. In the Playback tab, you can see the HDMI output device if port is ok. You just have to enable it to default sometimes.

Sometimes, video or picture does not come on the display device. Then if you have a GPU like NVIDIA etc, you have to go through its Control settings.

You may need to select the right settings as per your GPU manual. Also make sure the OSD Menu on your HDMI display device uses the right option or the correct key on the remote.

Problem with Multiple HDMI Ports

For example, many a times, when you connect a GPU, it has the option of 2 or more HDMI ports in PC.

Then to find out cause, like whether its cable or display device or the port, just plug the HDMI cable in the other port.

If it works, then that particular PC port may not be working.

Then you need to take it to a hardware technician to check the connection is proper with the GPU or on-board graphics card like Intel.

Compatibility Problems

Sometimes as I said before, the HDMI port, OS and graphics card may not be compatible with each other.

For example, Windows 10 needs the right drivers and control panel based on the graphics card. In other cases, you may need an adapter or the right driver that connects your HDMI port and GPU.
