How to Test Dead Pixels Using White Screen Tool

I wanted to share a simple and effective way to check for dead pixels on your screens using a free online tool called White Screen Test. This web-based tool displays a pure white screen across your device, making it easy to spot any dead or stuck pixels.

How to use it:

1. Visit https://whitescreentest.net/ on the device you want to test.

2. View the white screen carefully in a well-lit room.

3. Look for any dark or discolored spots, which indicate dead or stuck pixels.

This method works on all devices like smartphones, laptops, desktops, and tablets without installing any software.
