Many users have reported similar issues, which can be both frustrating and disruptive to your workflow. In this article, we will explore the potential causes of these issues, provide a straightforward explanation of the problem, and suggest practical solutions to help you resolve them.
Understanding the Problem
The original problem statement is: "Screen artifacts/pixelation at random on a few different Dell Latitude 3520 notebooks."
