Quick Screen Test — 2–3 Minute Pixel Check

The PixelExams Quick Screen Test is a short guided inspection for the most common display problems. It cycles through black, white, red, green, blue, and medium gray so you can visually inspect the entire panel.

Solid colors make small display defects easier to notice. Black can reveal bright or stuck pixels and edge glow; white can expose dim areas or uneven tint; red, green, and blue help isolate subpixel problems; medium gray can make image retention and uniformity issues more visible.

Clean the display first so dust is not mistaken for a pixel defect. Use the device at a comfortable brightness, view the panel straight on, and inspect the edges as carefully as the center. PixelExams records only the observations you choose and keeps them in your browser.

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