Advice on buying a good video editing flat screen
 

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?
