would be appreciated. Good for the eyes and worth its price. Two smaller or one big? Thanks

depends what you call "smaller".
for me 2x 24" is nice, but i would trade for a 30"
2x 22" is still ok, but i would prefer 1x24" instead 2x19".

Because of the edges of the screens being in the way or because of increased previewing possibility? Or do you use a separate previewing screen?
