You are catastrophically missing the point.
The great thing about this tech is not what it brings to current games on current monitors but what it can bring given a patch or two, and a bit of a change in the way displays are looked at.
You are living in a 2d world where you assume the display has to be flat. This brings us surround gaming, something far more exciting than building a wall if screens larger than could be practically done with a single LCD.
I will entirely agree that the center of the display will absolutely have to be on a single display (or a least across a bezel less border). But the possibilities we get from something like this, provided you open yourself to some imagination, are very neat.
Already current games confine the basic parts of the game to the center of the screen, to a certain aspect ratio. If you have ever played with a triple head to go you will notice that in most games what you get playing at 3*1680*1050 on the middle display is almost identical to what you get on a single display except that the HUD is moved to the far reaches. (something that given the market is easy to make variable if a studio bothers). You are not 'losing' anything by having the borders, you are expanding your peripheral vision beyond what it currently is (which is, of course, zero).
There are many examples of current and older games where this won't work, where the engine is not sufficient enough to add peripheral vision, and you run into problems. But that is not using much of the imagination we all are wonderfully gifted with. There is no reason the way Dev's treat a display has to remain flat. It is a very simple task to modify a shooter to have the HUD confined to a certain proportion of the screen, and have 'wing' pixels represent side, and even rear, parts of the screen. Imagine gaming with screens all around you. Sure, the bezels will still be there (of course depending on future tech) but what the extra pixels provide is the freedom to expand the game. You could play crysis just like everyone else, or you could play with the ability to be shooting and running in one direction while you glance beside you to check out the scene. I am not a game developer, I am sure the things that I can dream up are inferior to what someone at Crytek could come up with.. But it is set ups like this that has had me interested in multi display technology for a long time.
I am ecstatic to see that the resolution cap that matrox was stuck with (may the company rest in the peace of their business products from now on) is now gone.
Now we can have a display with effectively limitless pixels. Developers can start adding the freedom to change what each section of our now more than adequate displays can, well, display.
You may not find it important now.. but given a little while for this to mature (and of course for nvidia to hop on board.. as they will be forced to do rather quickly) you will want in.. everyone who is serious about games will. It may not seem like fun now.. but imagine when some games start allowing us to designate x*y pixels to be the action.. while another block (another screen in the real world.. at least until I get my OLED 'roll up' surround booth.. lol) shows a detailed mini map, or another angle of the action should you be playing an RTS. Imagine having the screen real estate to have your mission objectives, economy etc. all up at one time. Any fans of 4x's will be drooling over the amount of screen space we will be able to assign to empire trees without hindering our central display's view of the actual game.
Besides that, why would you have to center teh 3*2 block of displays on a border. Sure, you won't see a game right now that allows you to play slightly shifted to the left or right.. but it is not all that hard of a thing to do.. place the focus of the screen at -100, 0 instead of 0,0.
In addition to all of the fun things games might start to include if many gamers are now playing on triple wide (or whatever) display tech will change. There was up until now (except for some very special applications) no reason for a display manufacturer to care about how thick the frame of a display was, beyond practical size limitations. Really.. there is no reason the edges can't be 1mm wide clear plastic now, who knows what they will come up with when the LCD is predominately replaced by an OLED.
Granted, there are limiting factors.. but to poo poo the entire thing because of a short sighted assumption on its limitation is not wise. It may in fact lead to you getting ganked by someone who can look to their left in real time in only a short few months.
EDIT: I can't type tonight.. sorry for the type oh's.. also, I am not meaning to come off as attacking.. merely to point out the potential to this. Of course the short term gains may depend on the green team coming out with similar and not running a "multi-display gaming kills people" add campaign. I really hope this can easily be adopted by every gpu manufacturer so I can see real creative use in games in the near future. Blah blah blah, sick of gaming being held back for the politics of the business and all that...
