Blank Screen When Connecting Windows 10 Laptop to TV

Hi Antinet,

Thank you for contacting Microsoft Community. I understand that you have an issue with connecting laptop to TV.
I will surely help you to fix this issue.

To understand the issue better, let me know what is the make and model of the laptop?

This issue could have occurred due to these reasons:

1. Not connected properly.

2. Incorrect screen resolution or display settings.

Try the steps listed here:

Method 1:

I suggest you to disconnect the HDMI cable and try to connect it by following these steps:

a. Turn off your computer and position it within easy reach of your TV. Disconnect the monitor, but leave the mouse and keyboard connected.

b. Connect the appropriate video cable from your computer's output to your TV.

c. Turn on your TV and set it to the input that matches the output on your computer. You might need to refer to the user's guide included with your TV for instructions
on how to do this.

d. Turn on your computer.

e. You should see Windows displayed on your TV. If the screen looks stretched, or part of the screen seems cut off, you probably need to adjust the screen resolution
in Windows.

f. If you can't see Windows on your TV, you might need to reconnect the computer to your monitor and adjust the screen resolution before you connect to your
TV.



To adjust screen resolution follow this steps:

a. Right click on the screen and select
Screen Resolution.

b. Check if the resolution is set to 1024x768.

c. If it is not, then set it to 1024x768.



Method 2:

If the issue persists, I suggest you to change the screen resolution and check if it helps.

Hope this information helps. Reply to the post with an updated status of the issue so that we can assist you further.
