Running this test at 100% brightness allows you to see the true uniformity of your panel's backlight. For Dead Pixel Test specifically, it is recommended to check for Dead Pixel Test shifts and color inaccuracies across the corners of your screen. This is a must-have tool for anyone who has just purchased a new 4K or OLED monitor.
