The difference between 1080 and 720

This is why I was immensely relieved to read that the Imaging Science Foundation, the industry's top name in digital video testing, qualification, and certification, recently proclaimed that the difference between 720p and 1080p is much less than one would suspect. In fact, resolution ranks fourth on an image quality priority list behind contrast ratio, color saturation, and color accuracy. Outside testing done at CNET similarly confirms that professional evaluators could find only minor difference between the two resolutions and then only under certain circumstances.
