Contrast Ratio

i know what contrast ratio is in theory, but right now my monitor has 3000:1 and im looking to buy the 24 inch OCUK which has 1000:1

the question is how much diff will this make for me? will the black bars on the top (when watching a movie) be brighter? etc... also what would 1,000,000:1 contrast ratio be like (samsung OLED), the total black colour is totally turned off? with no backlight

cheers.

Some like Samsung list the Dynamic Constast not the actual Normal Contrast.

the dynamic to me seems to only lower the brightness when there is a dark image, (i never use it because its annoying as you see it switch)

1,000,000:1 contrast ratio, let's assume a white level of 500 cd/m2 would give you a black level of 0.0005 cd/m2. Compare with say 0.07 cd/m2 from a quality CRT, that's 140 times darker (from the OLED). I think in a pitch dark room your eyes would have serious difficulty seeing that as different from the black around you.

Of course that's assuming the 1,000,000:1 figure is accurate, which it may not be.

3,000:1 versus 1,000:1, yep the first one is dynamic, the second one static. You should get a better black depth with a 3000:1 dynamic contrast screen, as the backlight is dimmed, but only in dark scenes and it can cause nasty artifacts.
