Hey guys, just wanted to share some interesting info, rtings released a test for ASUS Vivobook S 16 Flip In which they mentioned that the display is OLED and the brightness dip is extremely small (take a look into a screenshot in a review). So maybe it could be useful for someone to try, and also as I do remember OLED displays are by design are 10bit, but I might be wrong. So anyway, some interesting device for test.
Btw I think its the first OLED display I saw with that extremely low brightness dip.
