How to test Kobo Libra Colour for dead pixels
Use the dead pixel test tool above. For the Kaleido 3 display, test on white, black, red, green, and blue. The 7" panel is larger than the Clara — scan the entire display carefully. The waterproof IPX8 rating means a small amount of moisture in the bezel gap is normal and not a defect.
