Something with complimentary bezels and screen sizes is the priority and ultimately I recognize that I will have to get a 3rd party mounting system to achieve the full effect.
I cant be the only one who has been curious about this so what has worked for you guys or what have you come across and considered trying?
Also, do you think there is enough interest for a manufacturer to consider creating a perfect pairing for interested customers?
I believe that 1 23"or 24" 1080p screen will have very very close to the same PPI as a 40" 4k screen. No idea about specific models that may go well together.
