Why is my Screen Flickering and Horizontal Dead Pixel Line on Acer Nitro AN515-54-563Y?

Hello,

I'm experiencing a persistent screen flickering issue on my Acer Nitro AN515-54-563Y. In addition to the flickering, there's a thin horizontal line of dead pixels that runs from one end of the screen to the other.

I’ve already tried:

Updating both Intel and NVIDIA graphics drivers
Checking Windows updates
Adjusting the refresh rate and display settings
Booting in Safe Mode
Testing with an external monitor (which shows no flickering)

The external display works fine, so it seems the issue may be with the laptop screen itself or its connection.

Has anyone experienced something similar? Could this be a hardware issue like a loose cable or a failing display panel? Any advice or suggestions would be appreciated.

Thank you.

Uninstall the Intel® UHD Graphics 630 driver completely in Device Manager and allow windows update to install the compatible Intel driver for your AN515-54 laptop (as the AN515-54 does not have the oem Intel graphics drivers used in the Acer support page) as that Intel driver would be the suitable driver to initally install.

Those screen lines, flickering and dead pixels are symptoms from the Intel graphics driver, as not all new Intel drivers are compatible with your Intel® UHD Graphics 630 chip and these new drivers do cause those symptoms. If its not the driver, then its a hardware issue where its either the eDP cable or the actual screen that is faulty and needs replacing. Good luck and hope this helps you out.

This issue is caused by the bad LCD panel. The only way to fix this is to replace it with a different panel.

There may be several reasons for your laptop screen flickering: Loose or damaged cable connection: A faulty cable connecting the screen to the motherboard may cause flickering.
Outdated or incompatible drivers: If your computer’s display drivers are outdated or incompatible, it may lead to screen flickering issues.
Faulty screen or hardware: A faulty screen or internal hardware component can also cause flickering.
Overheating: Overheating the laptop can cause the screen flickering issue.

Software issues: Some software or apps may cause some problems, leading to screen flickering.
Incorrect refresh rate: An incorrect refresh rate setting may also result in a flickering screen issue.
You can start by checking your HDMI, Display-Port, or USB-C cables. Ensure that the cables are securely connected to both the monitor and the laptop. Make sure that the cable is fully tightened and it doesn’t look or feel loose. This applies to all cable types, which can become loose for various reasons. Plug in your system to an external monitor to check if the issue reoccurs. If the problem does not occur on the external display, it may be due to a hardware issue with the laptop’s screen.

Next is to make sure that the graphic card driver is update. Outdated drivers may cause incompatibility, leading to screen flickering problems. Regularly updating drivers ensures optimal performance and a
flicker-free experience. Also to note overheating can cause hardware issues so, routinely check your laptop’s temperature to ensure it is not overheating. Make sure you clean any dust or debris from the vents and fans to improve airflow.
