If you missed the latest podcast from our friends over at CNET, I'll fill you in. Eric Franklin and Dong Ngo have a lively conversation about one of the latest marketing ploys, or as they put it, "company shenanigans."
The ploy? Dynamic contrast ratio. Oooh, sounds impressive. Kinda like contrast ratio, only more, well, dynamic. Unfortunately, this falls into one of those misleading specs — the kind that have no meaning in the real world. What is this sexy spec, and why is it so misleading?
As Eric Franklin explains, contrast ratio is a real measurement. A
luminance meter measures the difference between the darkest black image
on a monitor showing a black image and the brightest white. It should
be noted that he deals mostly with LCD computer monitors, and that's
his field of reference. A typical LCD monitor will have a contrast
ratio of 1,000:1.
All is good and well until manufacturers started touting their more
impressive dynamic contrast ratios of 5,000:1 or higher. What is this
magical dynamic contrast ratio?
