I'm trying to determine if it is a normal behavior for the OLED panel to flash a greyscreen with some colored pixels during power on before Alienware logo and then again before Windows login. In a bright room or sunlit area this is not noticeable at all- however, in a room with a soft lamp it becomes visible. While viewing from a darkened room the behavior is very obvious. It's very reminiscent of turning on my old CRT in the 80's and switching over to the Atari.
The "flash" does not persist- it is just a quick half flicker at the two points during boot. Otherwise everything appears normal and the display shows zero problems during use.
