Look at screen resolution more than screen size. 17" and 19" LCDs have the same resolution, 20" and 22" LCDs have the same resolution. So 2x 19" is like 2x 17" in terms of actual work area. And so on. So, why not a 2x 20" or 1x 20", 1x 17"? I suspect the price diff won't be too different from what you proposed?
From what you can read in previous threads, most people seem to think that the current batch of 22" wide screens are not that good for colour sensitive work as they are 6bit screens, whereas most 19" screens are 8bit screens...so maybe because of this 2 19" screens might be better...
but really, if above factor is not present, it depends on what you prefer... I have even worked on screens of 2 diff size, the smaller one only for parking windows...
That's why i'm still using my NEC Multisync FP1355. 6+ years and still my workhorse. Recently been having some probs with it not wanting to power up sometimes. I think it's a capacitor or something. Once it's on it works perfectly. Time to send for servicing. Believe it or not, it's first one in 6+ yrs. Too bad it's hard to find these type of monitors anymore.
The ips 30 inch Dell is very nice for photo editing. The very high resolution and large screen size makes life a lot easier. But it needs a high end video card. Go for this if you are serious. Good bang for the bucks at $1999. 'A' grade panel. U Won't regret.
Thanks for all of your responses.. I guess I will try to go dual monitor.. waiting for prices to drop a bit more before purchasing..;p
however.. I am thinking in getting a mac book pro... which is wide.. and connect the mon to it when i am at home.. for this situation.. is a widescreen a better option?...lol.. anyway to connect to screens to a laptop to have a triple screen
