== == Note: The below answer discusses "contrast ratio". "Dynamic contrast ratio" is a feature that automatically adjusts the contrast and brightness based on the darkness of the image. There is some debate as to whether this feature improves or worsens the quality of the display.
Yes, contrast ratio can be very important, especially when looking at LCD Tvs. Because of the nature of an LCDs lighting design, LCD screens have been known for not producing the best "Black Levels", that is, how dark the darkest parts of a video appear to the viewer. Some LCDs can appear to have more of a "gray" black level than a "black" black level, because the light source used to illuinate the LCDs picture can be seen at the borders of the display screen. The white light of the lamp, combined with the black of the LCD, makes the gray color. This is especially the case with very cheaply made LCDs, and even well-made ones with screens larger than 50 inches (for larger size screens, a plasma display might be a better option). OK, enough rambling, so, what is contrast ratio? It is basically a ratio of two values (i.e. 800:1, 10,000:1, etc.), where the first value is the "Brightest" value, and the second value is the "Darkest" value. Contrast ratio is the difference between the brightest white and the darkest black values of a screen. So, if your ratio is 10,000:1, then your display, at its brightest level, will be 10,000 times brighter than if the screen were completely dark. Naturally, the higher the ratio, the better your screen will look when you have the lights off in a room, and, unfortunately, the price of a TV will be higher. So, contrast ratio can be extremely important if you value a high quality image from an LCD display (it does come into play with plasma monitors, but it is not as important because the lighting technology is different). And if you have a good amount of money to spend on an HDTV, why not get a better image? Think about it, your TV is an investment, and if you like watching movies as much as I do, then you'll definitely want a TV that will give you a superb viewing experience for many years to come. I would like to make suggestion: Go into Best Buy or any electronics retailer where you can physically view and handle a bunch of TVs lined up next to each other so you can compare the differences in image quality. Let your eyes be the judge, only I will say pay special attention to the Sony and Samsung LCDs. I think they're the best on the market today! Hope this helps...I know it was a lot:) Happy viewing!

What is the difference between dynamic and native contrast ratio?
Static and Dynamic Contrast Ratios Faced with several different models of televisions from various manufacturers, the contrast ratio is one of the most important factors to consider in making your decision. A contrast ratio is defined as the difference between the lightest color and the darkest color the television is capable of producing. Basically, higher contrast ratios should yield more vibrant whites and deeper blacks. However, there are several important factors to consider when comparing contrast ratios: whether the contrast ratio is static or dynamic, and what effect your room will have on the visible contrast ratio. A static contrast ratio is the contrast ratio at a given point in time. Imagine pausing a movie and establishing the contrast ratio at that particular frame. Plasma televisions usually have vastly superior static contrast ratios to LCD flat panels. A dynamic contrast ratio is the overall contrast ratio the television can produce over time. Most LCD manufacturers now advertise dynamic rather than static contrast ratios, which often surpass Plasma TV's static ratios. Static and dynamic comparisons each have their pros and cons. A high dynamic contrast ratio is preferable for prolonged scenes that take place in dark settings or black and white movies in general. A static contrast ratio offers superior performance when there are sudden transitions from a well lit atmosphere to a darker one, and vise versa. ---- Recommended Contrast Ratios For Plasma Televisions» Static Contrast Ratio of 5,000 : 1 or a higherFor LCD Televisions» Static Contrast Ratio of 1,000 : 1 or higher» Dynamic Contrast Ratio of 10,000 : 1 or higher---- However, contrast ratio should never be your sole decision making factor. Firstly, most manufacturer's have slightly different ways of measuring contrast ratios. Secondly, contrast ratios are always measured in ideal viewing conditions (essentially, a pitch black room.) Depending on the lighting conditions in your room, your visible contrast ratio will generally be much lower than the manufacturer's claims. In short, a contrast ratio is a useful although imperfect benchmark for comparing different televisions, but it should never be used as a sole consideration.
How do you convert dynamic contrast to contrast ratio?
I'm an engineer, I've been researching this for sometime. The simple answer is it cannot be done, however as we like to do in my field we will give something approximate and conservative to go on. From what I've read and seen if you are being told dynamic contrast ratio it is likely 1000 to 2000 times the static contrast ratio. The multiplier will be different for EVERY brand comparison, but should general fall in this range.
Is a dynamic contrast ratio of 1000000 to 1 better than a static contrast ratio of 20000 to 1?
Contrast ratios on televisions screens get better and better with each model that comes out. Unfortunately, there are many ways of measuring contrast ratios and claims of ratios like 1,000,000:1 are using some very creative measurement techniques indeed. Contrast ratios are affected by many factors including ambient light levels, image content, production techniques during editing and more. While a high contrast ratio suggests that you will see whiter whites and even blacker blacks, the numbers really don't mean a great deal compared to your own eyes. Before buying, make sure you look at televisions and decide for yourself just how white and how black the image gets. More importantly, look for detail in the very light and very dark parts of the image. Rich blacks with some detail in the darker areas is good and the same for very light detail. Your own viewing will give you a far better comparison between two screens than the numbers ever can.

What does 5000 x1 or 20000 x1 mean in regards to HD televisions?
It is referring to contrast ratio. Contrast ratio is the range from blackest black to whitest white. that said "dynamic contrast" is B.S. (a huge manipulation of the numbers). Look for "Native contrast"
What is more important - resolution or dynamic contrast ratio?
most of the cases the resolution is important when it comes to large screens contrast ratio matters!! i mean lik the very large plasma displays!!
Which gives a better measurement for the quality of an LCD monitor the contrast ratio or the dynamic contrast ratio?
The contrast between true black and true white on the screen. The higher the contrast ratio the better. 1000:1 is better than 700:1. An advertised dynamic contrast ration is much higher than the contrast ratio, but not a true measurement of contrast. Dynamic contrast adjusts the backlighting to give the effect of an overall brighter or darker image.

How much dynamic contrast to ratio can the eye see?
There has been a breakthrough in LCD TVS recently. The Samsung LN-T4681F (AVAILABLE ALSO IN 40" AND 52") has a contrast ration of 500,000:1. Impressive. Sony also has an OLED TV with a contrast ratio of 1,000,000:1. When you get to 500,000 you see an almost perfect black. If you have a movie and the screen is black, you might think that the TV is off. When you see the 1,000,000: TV you definitely think it is off. the eye can detect any contrast ratio pretty much. But i think you mean what is the ratio when your eye simply sees black. and that is when you get beyond 500,000:1. It doesn't really get much darker and blacker than that.

Should i use a monitor with Static or dynamic contrast for photo editing?
Static contrast. With dynamic contrast the screen brightness gets lighter or darker depending on whether there is a lot of dark or a lot of white on the screen. This is an opinion of mine and I don't have any data to back it up except that I am a professional photographer and have used both.
