cant detect tv with hdmi

Hi,

Thank you for contacting Microsoft Community and welcome to Windows 10 family.

Please try with these steps:



1. Right click on the Desktop.

2. Choose Screen Resolution.

3. Let’s see if TV has been detected. If not, press “Detect” button.



Also go through the below steps:



Step1:



Choose the connection for video output. If your computer has an HDMI port, otherwise, you will need to make a few decisions. If your computer has only a single video output, and it will not be used solely with the television, you may want to invest in a
new video card. Purchase one with either a DVI or an HDMI output, and install it in an available slot, according the instructions included with it. If you intend to use the VGA output on a single-output or dual-output card to drive the HDMI display, then a
special device will be needed to convert between the formats, and the price of the converter is actually about the same price as an entry-level video card that will be easier to use with your TV. In that case, it may be a wise idea to upgrade the card in order
to obtain a DVI or HDMI port. However, if your chosen output port is of the DVI variety, an inexpensive DVI to HDMI cable can be purchased to convert your computer's output into the proper HDMI input for your TV.



Step 2:



Connect the HDMI cable from your television to your computer. Install the correct adapter or converter for your computer, if necessary. Unless your computer has HDMI output, cords will also need to be connected from the sound card output to the HDMI video
cable or adapter, because HDMI carries both video and audio signals.



Step 3:



1. Boot your PC, and configure the new display,

2. Go to "Control Panel" from the "Start" Menu.

3. Double-click the "Display" icon and click the "Settings" tab.



The manual for your HDMI TV will list the screen resolutions it supports, along with the refresh rates.

Configure the resolution in the "Settings" tab, and then click the "Advanced" button to set the refresh rate.

If you are using the HDMI TV as the second monitor, you will also have to configure how it is used by Windows, according to the instructions pertaining to your video card. Most cards offer a "Clone" or "Mirror" mode, where both screens display the same content.
Alternately, the "Extended Desktop" mode can be used, in which each monitor will operate independently.

Hope this helps. Please post us if you need any further assistance with Windows.

Thank you.

 

Why exactly is ATi considered be better at HDMI?

I plug my HDMI cable into the card, then into my TV. Those are the steps that I have to do. All the steps you list make absolutely no sense to me.

 

HDMI Port Stopped Working


I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?
