Tom's Hardware Reviews Multi-Display Gaming
MikShapi writes "Most gamers out there today own a dual-head graphics card (most of us completely neglecting the second port), and games such as X2 are offering support for this already (at least on nVidia cards, due to the "span" driver feature). Tom's Hardware did a nice rundown on the technology, complete with screenshots and benchmarks."
Meh, Seriously..... People are saying how cool this is but multidisplay gaming was being done on my Mac Quadra 840av back in 1989 or 1990 with an application galled Hornet by Graphic Simulations. We had three displays hooked up that could dynamically display front and side views as you moved the plane throughout its axis making virtual air combat much easier. Hornet was apparently written for the Mac natively, but later, when Graphsim decided they were going to write for Windows first and then port the Mac version, we lost the ability to do multidisplays even though the Macintosh had been supporting multiple displays since 1987.
Granted, at the time, a Quadra 840av with three fast NUBUS video cards and three displays were decidedly not cheap, but my point is simply that this is nothing new and when the original Graphsim creators of Hornet included this feature, they knew this was the right way to do it just like the more sophisticated simulators that pilots use for their training.

I had multi-display gaming on my Mac ten years ago. Chuck Yeager's Air Combat. I set the second monitor to always show the rear view, so if any MiGs or Messerschmitts started tailing me, I'd see it immediately. IIRC, the game would let you put a different view on as many monitors as you had.
Hell, one of my friends managed to get DOOM working with three displays on his PC back then, too, though it took him a day or two to figure it out-- mine was just (as you'd expect on a Mac) plug and play.
I found that continually turning my head right to left to view both screens put a real strain on my neck.
I tried moving back from the screens but I really couldn't find a "sweet spot" and eventally gave up.
I always save my last mod point to mod up a good troll. You people are too serious.
I think you would be wanting one of the Parhelia cards from Matrox Graphics. I'm sure some /. readers remember them. They're the company that refuses to die in the face of Nvidia and ATi, because they also sell other stuff in other markets.
Google for "Matrix Parhelia" to read the reviews.

With the nVidia drivers allowing you to span, games like EverQuest already support multi-monitor. I play EQ in 2560x1024x32 and it works out pretty well, letting me split the character information across the screens. And, honestly, you never really look directly in front of you that often, heh, so the screen split isn't that bad.

Done this a few times, works best if you have 19" monitors, roomate got seasick playing it. But he couldn't play Descent without getting nauseas either.
Atari tried to put this technology into arcades, with Race Drivin' Panorama. There were 3 and 5 screen versions, but only prototypes existed. Check some nice photos and specs here and here
I'm sure that having a second monitor to provide extra game info is probably way cool, especially with games like flight sims and driving sims. But how many people really have two monitors?
I bought 3 Hitachi 17" Flat Panel displays just for that purpose. I powered them with a Matrox Parhelia. (Screenshots here, here, and here.
For Flight Sim'ing, the experience is just OK (at best). And that's only if you turn down the settings quite a bit. The video card simply can't handle 3840x1024 resolutions with all the settings maxed out and still manage 60+ frames per second. (Though in flight siming, since the graphics don't change nearly as much as they do in a first person shooter, you only need 25-30 to get a smooth playback.)
I noticed that in first person shooters the extra monitors didn't actually add to the emersion like I thought it would. You still focus all of your attention on the middle monitor. The side monitors ARE good for camping/sniping though. You have a wider field of view so it's harder for someone to surprise you from the side. But when you are running around constantly, the side monitors can almost be more distracting than useful. But it makes for a great demo for friends. Everyone you show it to will want it.
The real problem with triple head gaming right now is lack of graphic processing power. Don't buy the Matrox card for this purpose. You definitely WILL NOT be happy with the results. I most certainly wasn't. And I bought it knowing that for first person shooters it was going to suck, but I wanted it mainly for Flight Simulators. But even in that case it just doesn't have enough power.
Maybe when PCI Express is available I'll be able to buy 3 NVidia/ATI based graphic cards that actually have the kind of power needed for this intense of a workout.
What Tom's Hardware is proposing in this article is a much more practicle use for a second (or third) monitor. Having the second monitor display map data, chat information, statistics, and so on. The second display wouldn't even have to be accelerated in that case. A spare PCI VGA card with 8MB or 16MB of RAM should be sufficient.
anybody remember these guys?

last i recall, they had fraud rumors flying left and right, but then they showed up to some convention or other with an actual setup and made everyone eat their words. i still think a lot of their desktop descriptions sound like complete hogwash, but whatever. that grand canyon display still looks pretty badass.

That which discloses to the wise and disguises from the foolish their lack of understanding.

I do exactly that with my GeForce FX 5700. As long as you don't need to interact with what's on the second monitor (most games grab the mice, so you can't move it to the other monitor), it works just fine.
What I would really like to do is to be able to chat on the other monitor while waiting to respawn, etc. on the game. Alt-tabbing minimizes all games in full screen mode, though.
Warning: Opinions known to be heavily biased.
My second monitor at home is a 17" LCD and was pretty cheap. Indeed, two smaller monitors will give you more screen real-estate than a single large one, for a much lower price.
If you do go down the multi-monitor route in Windows, I'd highly recommend Ultramon which adds invaluable features missing in the OS (taskbar on second monitor, maximize to dual-screen, button to flip window from one monitor to another, turn on/off second monitor, multiple profiles, etc.)
Second question, how does linux do with a second monitor?
:-)
:-)
Like anything with Linux, the answer is, "it depends on your distro, your [insert hardware model here] and what version of [insert relevant software here] you're running".
does it take any further customization?
Heh. Would it be Linux if it didn't?
Seriously, though, check out this HOWTO. The HOWTO's title is slightly misleading in that it covers dual head configuration in addition to Xinerama (which is lucky for us).
FYI, the Xinerama extension is what allows XFree86 to support the use of multiple monitors with one desktop (e.g., you can drag your windows from one monitor to another or have them span both, etc.). In the old days, you used to have a separate X session for each monitor. Most modern session managers (GNOME, KDE, etc.) now have good support for Xinerama, but you'll need a relatively new version of XFree86 (if you have a newer version of most distros, you should already have this).
It will also help if your monitors are relatively new. If they're not, you may have to do some Googling to get the proper modelines (search for "[your monitor model] xfree86 modeline"), but for most newer monitors, this should be an issue.
Another point of recommendation: if you want hardware 3d acceleration, try and make sure all of your cards support it. Otherwise the contents of your OpenGL app windows will not display on monitors without it. Not a show-stopper, but sometimes a little confusing/annoying when you're running Blender.

In arcade games they addressed that issue by putting one flat-screen CRT in place normally, and putting the other so the screen surface was on a horizontal plane showing a reversed image, and putting a mirror right up to the edge of the other CRT for the reversed image to reflect from so the image was as close to seamless as possible. It worked pretty well.
It was done in larger multi-player games like (IIRC) the 6-player version of "X-Men"
