Screen Testing Guide
Types of Dead Pixels
Dead pixels are classified as bright pixels (always glowing), dark pixels (not glowing), and color pixels (displaying wrong colors). New monitors usually have warranty policies, and dead pixels can be claimed for replacement.
Testing Environment Recommendations
Testing in a dark room environment works best, making it easier to spot bright pixels. It's recommended to adjust screen brightness to a moderate level to avoid eye fatigue.
Usage Tips
Carefully observe screen performance under each color, paying special attention to screen edges and center areas. If suspicious pixels are found, switch colors multiple times for confirmation.
