What is Dynamic Contrast Ratio, and why is it so important when deciding which TV to buy? This article, although short, contains the essential information you need to know. To start with, we'll look at contrast in general, before moving on to talk about "dynamic contrast".

The Importance of Contrast

Put simply, contrast is the relationship between the light and dark areas on your TV screen. For example, if you were watching a TV that didn't have good contrast, you wouldn't be able to make out much detail in the image, especially in the extreme shades. This is due to the black and white actually being shades of grey. So, if you get a TV that has high contrast, you can be sure to see the blackest blacks and the whitest whites.

Dynamic Contrast Ratio

TV manufacturers sell their TV's with specific contrast ratios. The thing is though, there is a difference between static contrast and dynamic contrast. Static contrast means just how much contrast you can get between the light and dark on the screen at the same time.

The dynamic ratio, on the other hand, gives a much larger number, because this refers to the difference between the blackest black and whitest white, at any time, not necessarily on the screen at the same time. Let's say for example that the scene you're watching is generally quite dark. This would mean you would get more contrast detail in that dark image than if there were brighter sections present.

Which Has the best Contrast Ratio: Plasma or LCD?

Plasma TV's definately have much better contrast than LCD TV's. To give you an idea, an LCD screen might have a ratio of 120,000:1, but a Plasma might have a ratio of 3,000,000:1. What a difference, hey? Plasma rules when it comes to contrast!.

If you’re looking for a TV with high contrast, here's what we recommend: For a Plasma TV with high contrast, look at the 42 inch Plasma HDTV. For a high contrast LCD TV, visit the Samsung 46 Inch LCD TV
