Acer Nitro 5 AN515-44 Screen Flickering + Lag

Hi! Bought my Nitro AN515-44 in March 2021, recently experienced screen flickering on my laptop. See videos here: https://drive.google.com/drive/folders/1i62NQnXwL6GXbEUw3DA_EApx0DQvp2jZ?usp=sharing

Day 1

- Screen flickering at the top whenever booting up/main screen

- Screen occasionally completely black/white, has after image of multiple screens after opening/closing other windows (looks similar to LCD burn-in but disappears overnight)

- Screen frozen/extremely laggy on the lower half below the flickering horizontal lines

- When using external monitor, everything runs fine, ACER boot screen also no problem and no flickering - only starts from the log-in

Day 2

- Updated AMD and NVDIA drivers to the latest versions, seems to have stabilized

- Problem starts again after laptop sleeps for 1 hr

- Had to use external monitor for the rest of the day after turning of main screen

Day 3

- After resting overnight, screen seems to be ok so far - flickering horizontal lines now only appearing at the log-in

Anyone had a similar issue before, and if so, how did you fix it?

Screen problems could be from nay issues, driver, eDP cable or power issues and/or the screen itself that can go wrong. As you have updated the drivers what I would suggest is for you to download the DDU software and completely uninstall the graphics drivers and then install the newest drivers for your Nvidia gpu and all AMD drivers for the cpu and chipset. As and if this flickering problem persists then its an internal a hardware issue not a driver issue. Check the eDP cable for the screen if its not damaged in any way, if its not then yiur laptop needs to be diagnosed by either Acer or an experienced tech that can narrow down the internal faults that your screens laptop has, which is complex as it could be a power or signal issue to the screen etc etc
