Some monitors have wider viewing angles than others, and when you change your angle of view, it's as if the image had undergone a gamma correction. For example, shadow detail in the monitor in our office is much darker viewed straight on, than it is when shifting the point of view upwards (e.g. stand up and look down at the monitor). Changing the point of view on my low-end laptop results in completely silly changes in the actual image colors, not to mention the amount of visible shadow detail. In a pinch, the office monitor could be used for image editing, the laptop, not really. Elle
