Most games will not take advantage of two independent monitors because games will generally display on only the primary monitor. When people game across multiple monitors, it usually is across three. I don't know off of the top of my head what support there is for playing across two monitors, but I assume it would be sub-optimal due to the bezels running down the center of one's field of view.

It should be. I believe the way you would force games to span both displays would be to stretch your desktop across both monitors (process is vendor (AMD, nVidia, Intel, other) specific). This would trick the games into seeing both monitors as one.

You won't, Nvidia only supports gaming on one monitor or across three monitors.

I guess now would be a prudent time to ask (should have asked it sooner), do you want the displays mirrored (showing the same thing on both)? If you do, it should be as simple as (assuming Windows 7) right clicking the desktop and going to screen resolution, selecting the second display and choosing Duplicate These Displays.

If that is not what you want, you may have to look more closely into a hack of somekind. Apparently, somewhere along the transition from XP -> Vista -> 7, the ability to span just two displays was removed (at least for nVidia, don't know about others). If you can't find a hack, I would just stick to one display for games (or go the mirroring route).

Nvida cards can still span the desktop across two displays but 2D surround requires three monitors.

Should clarify that I mean making the computer see both displays as a single large nonstandard display, which is kind of what nVidia does for 2D and 3D surround.

That is what an extended desktop gets "seen" as but it doesn't work for gaming unless you have three monitors all running the same resolution.

Not quite. In extended desktop, the displays are all still indpendent . What I am referring to is similar to what the new 4K displays do: they appear as 4 1080p displays, but they are combined into a single 4K display. In this case, what I am referring to would act as a single display in all cases.
