I'm using a gateway computer, and I've calibrated the monitor several times. Even though I've calibrated, the colors are still so far off. On this computer I can't adjust the contrast, and I think that has a lot to do with the problem. I'm looking to purchase something along these lines ( Datacolor Spyder4EXPRESS Display Calibration System S4X100 B&H ) Has anyone used it before, and does it help with contrast? Thanks in advance for any help given.
