Its funny, because I've heard conflicting reviews on the ZR24W. I've read about problems with the blacks, but I've also read the viewing angles are very good apart from the horizontal, which is more limited compared to other IPS panels. It shouldn't be as good as high end NEC's due to it lacking A-TW polariz.
Also for gaming I've read its good and you need to play with the overdrive settings to reduce the ghosting. So average gaming should be fine.
Regarding the LP2475w, I was leaning towards this panel, but I've read many bad things about it and people resorting to sending the monitor back. I don't normally put too much on these type of reviews, but I cannot disregard and I've got to re-read some reviews...
The NEC EA231WMi has higher input speeds and response times, which won't be good for gaming. I'm sure I've already read the bit-tech review on the NEC, but I'll take another look and see what they say about it.
I know what you mean, its all about what you see but I cannot see any of these monitors as no shops in my local vicinity have either displays.
Yea, I do prefer a 1920x1200 resolution. In fact I'm all about real-estate and I'd get a higher resolution if it was available and its one of the reasons I won't go to 27ich. 24 seems like a good size and I'm not sure if the extra 0.77cm width and 3.67cm high of the 24inch 1920x1200 res is worth the fuss.
