Well, now to the topic...
I'm not sure I fully understand what it is you're meaning. 2 monitors, one in front of the other.
You don't need 2 monitors to have an opaque overlay to have constant data on top of an application. Applications already exist for that.
If you had meant to emulate some sort of 3D, then there are also lenticular screens that you can put over the screen of you monitor and iff the
software supports it, you can get 'fake' 3D. Or there are other formats of screen overlays that require you to have a monitor that has a refresh rate
of 120hz or better.
Like a 3D tv, you can also have glasses that you can use that also require refresh rates of 120hz or better.
But as to why two monitors would be required to have a simple overlay, it's not feasible given that software can do this for you already.
I guess I'm just not getting what you're intending.
I still say 42.
