I suspect it depends on what kind of monitor you can afford. Its likely to fill more of your field of view.

But you could also just get a larger monitor so that it does fill your field of view. At some point its annoying to turn your head to see the whole screen so there is also a point it gets too big.

Its a virtual monitor though, so you can adjust it easily. I can certainly see the use in that, but on the cost side of things I would still go with a regular monitor.
