I will offer this:

WIDE screens provide a smaller viewing because as you know monitors are measured diagnonally. So, your VERTICAL space will be reduced. Personally, I prefer to use 4:3 instead of 16:9.

Having said that, look at the RESPONSE TIME and make sure it's 8ms or LESS. When you scroll music/waves, etc... a slower response time will make for a very obnoxious viewing, very distracting.

You can find excellent 19" LCDs with all the necessary specs for less than $200 each if you shop around.

I only use a wide screen for motion picture playback if I am scoring because it looks good...and it impresses directors :)

Your specs look OK. I would however prefer to buy those in a real store (i.e. not a webstore) because you'll have the chance to see them at work e.g. horizontal scrolling and make sure you have zero dead pixels.

Most 19" screens will "only" offer a bigger dotpitch over 17" on the same old 1280x1024 pixels.

My 17" 710Ns have a dotpitch of 0,264 and a comparable 19" like the 920N has 0,294. So the 225BW is in between at a dotpitch of 0,282.

How far are you from your screens? A big dotpitch will allow a bigger distance and enhance readability.

I do not agree with DIGIT on the "smaller viewing" remark. Especially if you can flip the screen to vertical view. Besides, 1680 x 1050 is still more display real estate than 1280 x 1024 in any way you look at it. It's just that you don't have the luxury of placing them as far away as you could with a 19", though it is still a bit more than a regular 17".

You plan to have two of those? 8-)

I prefer multiple monitors

I think it aids workflow and the max-min window is so quick.
Forever resizing and repositioning a window as programs are launched is a pain and you never seem to be satisfied.

so if you need more area,
keep 'em cheap and just get more of 'em

Triple screens for me
