This is basically two 1440p panels attached together... so not too different if you have really thin bezels.

But what I'm curious about is if this acts as one monitor or two? None of the images show windows that overlap the middle of the screen. So is it one or two "virtual" screens?

If it is one virtual screen, I might think of it as more useful to me in the 18:16 orientation.

From someone that does a 3x2 setup I'll add one downside: on my split setup I run the bottom row 90 degrees from the desk while the upper ones are angled down and slightly so that both are viewed straight on when glanced at. Not having a physical split like this makes it so the top and bottom will always seem angled.

I suppose if it were curved it'd solve that problem but then it would come with assumptions about how far away you sit and create new problems like glare streaks.

Also easier to reposition as a single unit.

More flexibility when splitting stuff? With 2 screens, I often found I wanted a main thing in the middle and a small window on each side, but that's really ackward if you have a bezzle. Then again, that makes more sense for an ultra-wide than an ultra-high monitor in my opinion.

Only one image (unless you use the split feature) with no gaps in between, and only power input.

no bezel comes to mind. also easier to mount than try to align two perfectly
