Why Use a Free Tool to Test LCD Screens?

Here are a few reasons why using a free tool to test LCD displays is a smart choice for diagnosing and maintaining your screen’s performance:

Detect Dead and Stuck Pixels

One of the main reasons to test lcd online is to check for dead pixels. These appear as small black spots that are visible against any background color.

Detecting these issues early allows you to address them before they worsen.
