I came across an article/YouTube video/comment somewhere a few months ago that stated the reason we don't have 5k 27 inch OLED monitors is because the pixel density is too high for OLED to handle. But this display seems to contradict that. Anyone more knowledgeable on display tech have any comment?

I would be keen to replace my 5k iMac (converted to work as an external monitor) with a 5k OLED monitor!
