Removing Scan Lines: The Complete Restoration Guide

Scan lines are basically horizontal artifacts that appear on monitors, video recordings, and TVs. These artifacts affect the display quality and occur due to faulty hardware, improper video settings, or interlacing. Regardless of the cause, the issue is concerning and can be resolved through various software and hardware solutions that will be mentioned in this guide. So, review the article while exploring the best possible solution to remove scan lines.

Part 1. What Should You Know About Scan Lines?

As mentioned, scanner lines occur due to numerous causes, but do you know what type of lines you are facing? To determine this, let’s explore a few kinds of scan lines mentioned below:
