Here I tried something new and I think I got a pic to finally show the difference of my screens so people can understand where I am coming from.
You can in this pic see the difference of variations between the two. The K4 is a light grey and the K3 a creme even though it's in the one in shadows if I put it in the light it's gets near off white, no grey to be seen but I am trying to show the K4s and my K3s difference not the brilliance of my K3 screen.
