Free Online Screen Test for Pixels, Burn-In, Banding and Touch

PixelExams is a free browser-based display inspection suite for phones, tablets, laptops, monitors, and TVs. Use guided full-screen patterns to look for dead or stuck pixels, screen burn-in, uneven brightness, dirty screen effect, banding, backlight bleed, motion problems, and touch-response gaps.

Nothing is uploaded and there is no account to create. The tests run on the device you are examining, making PixelExams useful for checking a new display during its return window, inspecting a used device before purchase, or documenting what you observe before contacting a manufacturer or retailer.

Start with the quick exam for a short red, green, blue, white, black, and gray check. Use the complete screen exam for a longer pass that adds secondary colors, gradients, motion, and a touchscreen grid. Dedicated tests are also available for OLED burn-in, uniformity and banding, monitors, phones, TVs, and suspected stuck pixels.

PixelExams is a guided visual inspection utility. It does not automatically diagnose hardware defects, calibrate a display, or determine warranty eligibility.
