Help
Monitor is LG 20MP48AB (2017).

A few days back, a vertical line started blinking every 7 seconds, disappearing within 2 seconds.

Since we can't memorize everyone's specs, can you please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. Include the BIOS version for your motherboard as well.

Have you tried changing display cables to rule out a cable issue? Have you tried connecting the display to another display source to rule out the display as the issue?

I have no idea it can be an issue with PSU, BIOS, and the motherboard. My sincere apology.

I will try all your suggestions posted above. I hope they will resolve my problem

I removed the D-SUB connection and switched on the monitor, but it still shows the same problem. Therefore, there is an issue with the display.

Has anyone had a similar complaint, and is it repairable?
