Yes. One bigger is better. I chose two screens because I didn't think I would like the small images on a split screen. I seldom use the split screen. So now I am kinda stuck with multiple screens that have a smaller image (harder the dilemiate details). Whereas, if I just took the money for the multiple units and combined them into a much larger single unit, I'd be happier.
I vote single larger unit.
