In modern LCD monitors, is there any noticeable difference between a 15000:1 (e.g. this monitor) and a 50000:1 (e.g. this monitor) contrast ratio? Or is it just marketing hype?
Same thing with a 2ms vs 5ms response time.

1:50000 is definitely marketing hype. They measure the white at the brightest backlight point and the black at the darkest backlight setting, or even turned off! S-IPS monitors are aroun 1:700-1:800 in real life today TN and H-IPS monitors are around 1:1000 S-PVA monitors get up till 1:1400 S-IPS big screen TV's get to 1:2000 S-PVA big screen TV's get to 1:3000 Plasma's can get to 1:5000 That's about contrast in reality. All higher numbers are worth nothing.\
About the respons time: There is two things to consider in this:

If I was you, go to your local big computer shop and try to find either the same model or ones with similar specification to compare.
A lot of it is marketing spiel. I see monitors all the time that say fastest 2ms refresh - never see blur again e.t.c. - I am using a 7 year old NEC monitor (1880SX) that has a refresh rate of 33ms and a contrast of (I think) 250:1, at its time, it was also rated as "never see motion blur again!" - I think it is brilliant and would not change it for the world.
I have a second monitor that is newer, MUCH higher specifications, however you would think it is older when you look at picture quality (however, it is still not bad!)
Also, shockingly, Manufacturers lie! even if one has a higher rating than another, it may have been under a special condition that you would never be able to repeat. The only real way to compare is to buy it, or look at the model and see!

Contrast ratio is something desirable to look for when purchasing a monitor. You see colors at their "fullest" so to speak. Whites at their brightest, black at its deepest and darkest (even though you will probably never set them very high). Wikipedia explains it better than I can:
The contrast ratio is a measure of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing.
As with response time, it is what it sounds like - How long the monitor takes to respond and change its pixels from black to white or vice versa. Typically you won't notice, but to gamers it's pretty important and makes things look smoother :)
Ok, but I know what contrast ratio and response time are... I was asking if there's any noticeable difference between those values. – Mauricio Scheffer – 2009-09-26T00:10:37.150

You'll also notice for most of the ones that advertise a 2ms refresh, it's only GTG (grey to grey). – John T – 2009-09-25T04:53:10.347

Samsung has a history of coming up with enormous contrast ratios. I've always been skeptical of their specs. – alex – 2009-09-25T05:48:16.413
3Manufacturers don't lie, they just tell a different version of the truth. – Josh Hunt – 2009-09-25T07:25:35.373
