Testing Instructions:
- Turn off all room lights so your testing environment is dark.
- Set your monitor brightness to 100%.
- Press F to enter full-screen mode.
- Look around the perimeter of the panel where the glass meets the bezel. If intense yellow/white patches intrude inwards, take a photo from at least 1.5 meters away to document a warranty claim.
