Hello, I read that Apple may offer a 5K monitor this fall. Not sure if I should wait. I saw some 4K monitors in store. They are quite good. What are the pros and cons of 5K monitor? Is the different in image quality noticeable? I guess at 5K, it may be even more difficult to read the letters as they become even smaller. Given that iPhone can only shoot 4K video, what is the point of getting 5K monitor?
