That contrast seems awfully low to me, but you never know until you lay eyes on a monitor. I generally don't buy a screen I haven't tested myself for that very reason. If you can't physically test before you buy, make sure your vendor has a good return policy...
And the EIZO S1911SH has a TN panel. It means, fast responses, not so good blacks, and lower viewing angles. if you move your head in front of the monitor, color and lightness will vary. this is not good for movies, but 2ms is good for games. http://www.eizo.com/products/lcd/s1911_01/spec.asp
I should mention that the cost at my local vendor is:
EIZO S1911: 379Euro
EIZO S1931: 499Euro
They have an excellent return policy too.
Hhmm... Now I'm in a delima as both Anime & Games are very important in my book and wouldn't want degraded performance in either of the two fields!
