White horizontal line on 27AQDP 480hz

[JasonEguerre]

I’ve been experiencing a persistent horizontal subtle white line on my ASUS ROG Swift OLED PG27AQDP monitor. Here's what I have tried so far to resolve the issue:

1. Upgrading and downgrading the firmware.

2. Unplugging and using both HDMI and DisplayPort connections.

3. Powering off the monitor and unplugging it for 20 minutes.

4. Resetting the monitor to factory defaults.

5. Performing pixel cleaning with 60-minute intervals between the cleaning runs.

6. Trying different resolutions and refresh rates, clean install windows and all drivers.

Despite all these efforts, the horizontal subtle white line persists. Has anyone else experienced this issue and found a solution? Any help would be greatly appreciated!
