DEAD PIXEL TEST
Cycle solid display colors to make dead, stuck or abnormal pixels easier to spot.
Inspect each solid color for pixels that stay a different color. Browser fullscreen can also be entered with your browser's fullscreen control for edge-to-edge inspection.
How to check for dead pixels
Clean the screen first, then inspect every area on black, white, red, green, blue and gray. A pixel that remains dark or the wrong color across test screens may be dead or stuck.
