Hdmi issues when connecting laptop too external screen.

I have my doubts that plugging your laptop in would have damaged the ports, but it's worth checking, try using a completely separate (functioning) screen and display cable. This could be a monitor, or another TV, whichever you have at your disposal, if you suffer from the same issues, it has to be the laptop.

It is not fully clear which screen was producing static, was it the TV?

What operating system/version are you on?

Preemptively, let's get some information out in the open so other members can hop in without having to backtrack and ask a bunch of tedious questions:

Please download and run speccy.

Once you have ran speccy, follow the instructions to upload a snapshot found here.

To publish a Speccy profile to the Web:​

1. In Speccy, click File, and then click Publish Snapshot.
2. In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.
3. Speccy publishes the profile and displays a second Publish Snapshot dialog box. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Another thing for you to check:

Settings > System > Display

See if the screen is being recognized by the computer through the settings.

Please run through the steps in post #3 and we'll go from there.

On a side note: No need to quote replies, the system will automatically organize them by time sent. 🙂

A few things:


1. You are running low on system space, try deleting some old files/programs and running the following programs, try to keep at least 20-25% of your disks as free space.

Run Disk Cleanup (check all the boxes) this will delete things such as your recycling bin, so make sure you don't have any files you want to keep.

Run Defragment and Optimize Drives, run this on your drives.


2. Disable any overclocking or changes to power/performance settings

Turn off XMP/any overclocking you may have done (if any)

Settings > System > Power and sleep > Additional power settings
Make sure your power plan is set to balanced, anything else could tamper with the wrong settings and cause issues.


3. Check for Operating System Corruption

Right click on the Windows logo in the bottom left and select Windows Powershell (Admin)
Run these three commands separately:

sfc /scannow

Dism /Online /Cleanup-Image /CheckHealth

Dism /Online /Cleanup-Image /RestoreHealth

These will take a while to run, do not close out of Powershell while they are running, if one fails then move onto the next and then loop back around.

Note: Make sure you have a system backup before you make all these changes, save any important files of folders. While these changes shouldn't cause any issues, better to be safe than sorry.


Once you have completed all of these tasks, plug your laptop in, restart it (using the restart option in the power menu) and re-test.


Finally, is there are particular reason you are running Kaspersky? Windows Defender + a bit of precaution will keep you safe and prevent extra antivirus/antimalware from gumming up your computer.

Any news on this?

Any updates?

Do you have a USB C port to plug a display cable into?



An adapter like this or a usb c to hdmi cable would work fine.

If the display works fine with another computer, I would think that HDMI port on your laptop is gone.

I would test the exact same cord and monitor one more time on a different computer, if you can find a USB C to HDMI adapter, I would pick it up to test with.

Otherwise you might be best off to take it in to a local pc place and have them look at it.

What happens if you change the 2nd screen to 60MHz
