Dead pixel test free online screen test
This test cycles your screen through solid red, green, blue, black, and white so a dead or stuck pixel stands out against a uniform background. Run it fullscreen in under a minute — no download, no signup, and nothing leaves your browser.

Is Your Screen Actually Defective?
Not every bright spot, glow, color variation, or motion artifact means your display is faulty. ScreenInspect helps you understand what you're seeing and what may be considered normal for your display technology.
Test Any Screen
Phone Screen Test · Monitor Test · TV Screen Test · Laptop Screen Test
Whether you've just unboxed a new device or you're troubleshooting an older display, run the relevant tests before you decide what to do next.
Just Bought a New Screen? Test It Before Your Return Window Closes.
Check your new monitor, TV, laptop, phone, or tablet for common display problems while you still have time to act.
