I am not much interested in photo editing and print. I came here because I'm interested in color accuracy and want to know that the content I am viewing whether it be a movie, or a game, be what the developer intended for me to see..... With that said, I've recently purchased the SypderX Pro and have been trying to calibrate my monitor. I have tried a few methods, including the methods laid out here (I followed them precisely). The thing I'm not sure about exactly, however, is how to determine what type of LED backlight is in all the different monitors I've tried calibrating. Sometimes the calibrations do not turn out very well. Oftentimes I end up with a green hue/tint to the overall monitor image and I think this could perhaps be contributing to the problem. One of the monitors I've been calibrating is the Dell S3220DGF.
