Windows 10: HP Notebook 15 pushing a dvi output to hdmi TV, need to force hdmi.

After a month or two on giving up on trying to get my computer to push sound to my TV, i notice whenever i turn the laptop on, the TV says that a DVI input is being made, and I've got a feeling that is part of the problem. I have a feeling the laptop is the problem because i use my Xbox on the same TV and it outputs sound perfectly on both of the ports. I have got no idea why or how my computer would push a DVI signal through an hdmi cable, but if i could figure out how to force a hdmi signal, my problem may be resolved.

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.
