HOW TO TEST
Step 1: Prepare Screen
Clean your screen thoroughly with a microfiber cloth to remove any dust particles that might be mistaken for defective pixels.
Step 2: Run Test
Click 'START TEST' to enter full-screen mode. Cycle through solid Red, Green, Blue, White, and Black backgrounds.
Step 3: Inspect Results
Inspect each color closely. Look for spots that do not change color or remain dark. These are indicative of hardware failure.
What Are Dead Pixels?
"A dead pixel is a non-responsive sub-pixel that remains permanently black, failing to emit light across all RGB channels due to hardware failure."

The test generates high-purity color signals at your native resolution. This ensures that every individual sub-pixel is addressed directly by the display driver without scaling artifacts.
