Hey all, I don't usually post help threads (been a while since I have) But I recently bought the brand new Dell 28" 4K monitor, and am completely blown away. Yes there are some limitations that come with entry level technology, especially with 4K just coming (slowly) into the mainstream. I went out and bought a Spyder4Pro to calibrate it, and I just can't seem to get it right. After trying various settings, I am using a profile from my older 20.5" Dell and it looks spot on. Being a new monitor I am very slow to trust the output, and constant look at my images on other screens to be sure, so far so good. Now I don't want to have wasted $150 on this thing, anything that I am doing wrong or what can I do to get better results? I have played around with output settings, Kelvin temperatures, and always seem to get a magenta/brownish cast on the screen, and as such WB is way off and B&W images are not even close to B&W. Any tips?
