Ok, basically what I was thinking was, since OLED screens can be made completely transparent afaik (saw a news post a few months(?) ago that showed a TV you could see through), then that means you could also stack them, to have a multi-layered screen, or an eyefinity setup that was much easier to transport, depending on preference/space constraints.
The back screen would have a backing so it wasn't transparent, and would display whatever game/movie/your desktop background/etc.
the middle screen would pull out to the left, and would be the default screen for using as an extra display, for, say, displaying the leaderboard in an fps, or character stats in an rpg, chat in an mmo, etc (if games were made compatible with it, of course), or just displaying webpages/ a movie while you game (I know a few people that do this, atleast while grinding in MMO's).
From what I know of 3D technology, the back and middle screens could work in conjunction to create a better 3D experience, that, theoretically, based on my limited knowledge of such things, would tax the gpu less than having a screen run at 120hz, and you could also use the fact the screens are stacked to your advantage to create a 3D effect. (remember, I have a very limited knowledge here, so don't get mad if I'm speaking out of my ass).
The front screen could be used just for the HUD/subtitles, which, (again, according to my very limited knowledge) could most likely be done with most newer games, given properly programmed drivers for it.
This way, instead of taking an SS and having the ugly HUD/text in the way, you could take an SS of just what one screen is displaying, or, if the HUD is getting in the way, you could simply turn off/increase the transparency of the front screen (will elaborate later).
Of course, I would also think that this would be good for those that like eyefinity, but have lan parties, or dont REALLY have the extra space needed for 3 screens, plus, since OLED can be bezel-less (again, afaik) it would make for a nice, unbroken view, seeing as all 3 screens are made to slide out so far, and possibly click into place (and be able to swing back and for ~20 degrees, for better viewing angles).
I also think that a (probably wired) controller that can change transparency levels, viewing mode, on/off, etc on the fly. Say, 3 power buttons, with a slider beside each of them, and a button beside each slider (to select whether or not the screen is pulled out, all 3 pressed down means eyefinity mode).
Though, how many screens can a single plug handle I wonder...
And yes, I would suggest each screen has its own display inputs, I highly doubt any of our current cables have the sort of bandwidth needed for such a high resolution.
So, what does OCN think, a semi cheap (guessing it would be atleast slightly cheaper than buying 3 screens, due to the fact they can surely share certain components with all 3 screens), much more portable, eyefinity setup that could possibly do 3d when not in an eyefinity setup, that makes screenshots easier to take, can add difficulty to the game/make the HUD less in the way (change transparency, or turn off HUD screen altogether), and display anything you want without needing to have a second screen handy.
Of course, for this to take off, it would require a substantial amount of programming/drivers to properly manage all 3 screens, as well as gpu/game developers to like the idea and support it through their programs, etc.
All this was thought up in about an hour of being bored in class >.>
