After a long struggle hooking up my cintiq to my IMac, I finally have the screen showing on my tablet. For some reason, though, the screen has a blue tint to it. I've gone into the image options on the cintiq and tried changing the color temperature (6500K), that didnt work. I've made sure everything was connected properly, now I"m just at a standstill. Does anyone know what may be the issue?
