some monitor has 8000:1 ratio and some has even lower like 600:1. also there is a a "Ms" thingy which i dont understand. can some1 explain the benefit of higher or lower ratio and higher Ms Vs lower Ms. some monitor are expensive with lower ratio and high Ms and some higher ratio lcd monitor is expensive too whith lower Ms. im quite confused. so please help me explain these 2 attributes.
Contrast ratios are a big marketing tool by the manufacturers and one that is not easy for consumers to grasp. Essentially, this is the measurement of the difference in brightness from the darkest to brightest portion on the screen. The problem is that this measurement will vary throughout the screen. This is due to the slight variations in the lighting behind the panel. Manufacturers will use the highest contrast ratio they can find on a screen, so its somewhat deceptive. Basically a higher contrast ratio will mean that the screen will tend to have deeper blacks and brighter whites.
what about the "Ms" how it contribute to the ratio?
In order to achieve the color on a pixel in an LCD panel, a current is applied to the crystals at that pixel to change the state of the crystals. Response times refer to the amount of time it takes for the crystals in the panel to move from an on to off state. A rising response time refers to the amount of time it takes to turn on the crystals and the falling time is the amount of time it takes for the crystals to move from an on to off state. Rising times tend to be very fast on LCDs, but the falling time tends to be much slower. This tends to cause a slight blurring effect on bright moving images on black backgrounds. The lower the response time, the less of a blurring effect there will be on the screen. Most response times now refer to a grey to grey rating that doesn't do the full on off state that generates a lower time than the traditional reponse times.
if so then why some monitor with 1000:1 ratio and 2ms are expensive than a monitor with 800:1 ratio and 5Ms? (im referring to wide screen)
for example 19'' WideVX1940W A+D 1000:1 2ms - Price $217 and 19'' Wide VA1926W A+D 800:1 5ms - Price $185.39
