Hdmi issues when connecting laptop too external screen.

[leelee2320]

Hi , I plugged in my power supply to my Msi laptop when it was on low power while it was plugged by into tv screen via hdmi . The screen immediately started making a static noise while the display also displayed badly and staticky . After turning off and restarting the display was not working but the laptop was picking up it’s connected . Now the screen connected but barely displays image which is staticky before it cuts out too a black screen. Screen seems to be displaying normally on my dedicated laptop screen. I’m concerned that somehow plugging my laptop in has damaged my hdmi port . Any help to resolve this issue would be great .

I have tested the hdmi cable and screen , they work perfectly on other laptops .

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.

Another thing for you to check:
[COLOR=rgb(184, 49, 47)]
Settings >[COLOR=rgb(184, 49, 47)] System >[COLOR=rgb(184, 49, 47)] Display

See if the screen is being recognized by the computer through the settings.[/COLOR][/COLOR][/COLOR]

[COLOR=rgb(184, 49, 47)][COLOR=rgb(184, 49, 47)][COLOR=rgb(184, 49, 47)]
It does detect second screen . I am able to switch between duplicate and the like . Screen doesn’t display or display is glitchy / filled with static.[/color][/color][/color]

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

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.

1. 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.

1. 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:

[COLOR=rgb(184, 49, 47)]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?[/COLOR]

I will try this .

try using a completely separate (functioning) screen and display cable.

Yes I tested it on a different screen and still no response.

Any updates?

[leelee2320]

Followed the instruction still same problem

[Pyro]

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.

[leelee2320]

i do not have one

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.
