Interesting thread. I've also been doing research about this lately. After several hours, I ended up ordering the Dell P2415Q 24' Ultra HD 4K Monitor. I paid $409.99 with no shipping or tax from B&H.
This model apparently works well with MacBooks (pro, retina, early 2015) as it supports the (mini) DisplayPorts. If it's good, I'll order another to have a fresh two external monitor setup. It's supposed to arrive by Monday 12/07/2015.
I don't mean to rain on your parade, but I think that's a terrible decision. 4K is worthless for trading on a display any smaller than 40", because of the DPI scaling required.
The price is also ridiculous for a 24" monitor.
I like Dell, and have owned many. But in this case, bad decision in my opinion.
I would discourage anything over 42" for use as a monitor. With the 40", you already have to move your head side-to-side. With three of them, the far left and far right are titled inward so it's not as distracting. But a single 50" display would be a deal breaker for me, I would hate it because you can't read what's on the edges of the screen.
Honestly, 40" 4K is the sweet spot. It's perfect. Smaller than 40 and you need scaling. Bigger than 40 and you can't see the edges.
do you still think 4k 40in curved would be better than 4k 40in flat? i guess it mostly depends on the setup but lets just say 3 next to each other on the desk like so:

The curve is subtle. I would say there is an advantage with the curve, whether it's one or three. But it's not going to make a big difference either way.
BTW, if I take your example literally it would never work. The monitors on the outside must be angled inward pretty substantially, and you must have a very deep desk to make it all work.
You cannot put them side-by-side. Not even two. It isn't usable, for the same reason that a single 50" isn't usable as a monitor.
Please understand, I am talking about using it as it should be used. Meaning 4K, no scaling, and everything readable. Obviously you can use a 120" projector if you want, as a monitor, but you'll be 20 feet away from it and will have to use ridiculous scaling which entirely defeats the purpose.
You'd be better off with a 24" 1920x1200 display than a 120" projector, when it comes to actually using charts and not watching movies.
i guess im just having a hard time wrapping my head around it. if the scaling is fine for 1 4k 40in screen right in front of you, why wouldnt it work for 1 on either side of it?
