Line on the bottom of my screen when switching from 144hz to 60hz

Hi, yes i've tried all those options, yet the issue still remains. I did a clean install of both drivers, intel and nvidia with DDU and the issue is still there. All drivers are updated, did a clean install of the drivers at least 5 times. The issue disappears for a minute, hour, day or two, but always comes back. The laptop is still under warranty but i don't know how to explain the issue to the place i bought the computer from, i don't know what part of the computer could be failing. I've also ran sfc/ scannow several times and everything always comes back fine. Any ideas?

Hello, i tried installing an older driver but that did not fix the issue. It is very visible when i lower the screen brightness. I got a picture of it from my cell phone. The resolution is the same as the screen. I use 60hz for gaming because i find it much better, the issue started happening out of nowhere. Could it be a screen issue? It doesn't appear when at 144hz. notice the bottom of the screen

I tried all the things you said with no success except the external monitor because i do not have an hdmi cable at the moment. I also have no issue when using the integrated intel graphics card. I edited the post with a new picture of the issue

"Could it be a screen issue?"

Yes, i said to test another monitor. Please read and complete all steps.

Hi Eminent. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.

1. Can you avoid having to change to 60Hz if it is causing this problem?
2. The Display driver is so important here that merely updating it is sometimes not enough. So let's try everything possible to get it working correctly:

First make sure you have updated the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

If necessary first remove the old driver using DDU https://www.wagnardsoft.com/content/ddu-guide-t... (not necessary with Microsoft Basic driver which is a placeholder if nothing else is available) and/or installing in Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods: https://www.digitalcitizen.life/4-ways-boot-saf...

If new driver still won't install DDU see Lightning Leon's Answer here: https://answers.microsoft.com/en-US/subject/for...

If this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Intel driver update Utility here: http://www.intel.com/content/www/us/en/support/...

or the Nvidia GeForce scanner here: https://www.nvidia.com/tr-tr/geforce/geforce-ex...

or the AMD autodect utility here: http://support.amd.com/us/gpudownload/windows/P...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver.

You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

Adjust the screen resolution until it fits and looks best at Settings > System > Display.

3. What has solved this for others if nothing else does is to change the monitor? Do you have another monitor to confirm if this still happens. If not try resetting your monitor following the procedure given in it's Manual which is always available on the manufacturer's website or by a search for the model + Manual.

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.

Happy Holidays!
