PROFESSIONAL SCREEN DIAGNOSTICS FOR YOUR iPHONE
Is your iPhone screen acting strange? Dead pixels? Touch not responding? Before visiting an Apple Store, test your display yourself with Screen Tester - the most comprehensive screen diagnostic tool available.

WHAT YOU CAN TEST:
Solid Color Tests
Display pure colors (white, black, red, green, blue, yellow, magenta, cyan) to detect stuck or dead pixels. The most effective method for finding screen defects.
Gradient Test
Check for color banding, uneven transitions, and display quality issues. Perfect for identifying OLED degradation.
Dead Pixel Detection
High-contrast checkerboard pattern makes even the smallest dead pixels visible. Test every single pixel on your screen.
Burn-in Test
Detect OLED burn-in and image retention from status bars, navigation elements, or static content. Essential for used iPhone buyers.
Grid Pattern Test
Verify screen alignment, uniformity, and detect warping or distortion. Check if your screen sits properly in the frame.
