i was thinking of buying new 19" LCD..any recommendation between
-19" ACER AL1916WAS; RSP 8MS; C.R 600:1
-19" SAMSUNG 940BW; RSP 4MS; C.R 500:1
-19" LG 1952S; RSP 8MS; C.R 1600:1
-19" VIEWSONIC VX922; RSP 2MS; 650:1
what is contrast ratio?the highest the better?
Contrast ratio is actually the ratio of luminosity of the brightest and the darkest colour a monitor is able to produce. It can be simply explained as how white is white and how black is black as well as other colours. The higher the the contrast ratio, the bigger the difference between them.
When you watch a movie, sometimes you could see the blacks aren't as black but rather greyish and the white isn't that white but rather beige. That is the result of a lower contrast ratio. A good monitor with high enough contrast ratio should display black as in pure black including the different shades of black and also white and its shade accurately.
So YES, get a monitor with the highest contrast ratio your money can buy. Take note that there are two types of measuring contrast ratio that is denoted as dynamic or static. Monitor contrast ratios are usually denoted as static contrast ratio. If I'm not mistaken, LG denotes its contrast ratio as dynamic. That is why its contrast ratio is usually higher than the competitors. This could be a little misleading.
In my opinion, you could put Samsung as a reference so that you could make comparisons better and accurately. You should also take other parameters into consideration when choosing a LCD like panel type, colour reproductions, response time, etc.
