Re: I don't need 4k
You will not have a choice!!! Only 4k will be available within 5 years.
it is expensive fof manufacturers to operate production lines. Therefore they will move to making ONLY 4K resolution screens quite quickly.
Look around the shops and you most don't offer less than 1080p at 32" or higher now.
Its even rafe to find sub_HD screens at smaller sizes now.
The same will happen for 4K.
although, do note, that having cracked 4K the manufacturers are already working on 8K as their next-generation revenue maker.
