    Re: Crossfire with Dual Display

    I have no personal experience with CrossFire, but my understanding is that with Crossfire enabled dual monitors are Not allowed. As you probably know, you can use CrossFire and two video cards to increase the supported resolution using a very high resolution single monitor (which is not part of your hardware list). So it sounds like you will have either a knock out, single monitor, 3D gaming experience, or dual monitor support at "normal" rendering speeds. Sounds pretty good in either case.

    Re: Crossfire with Dual Display

    Paul - Thanks for the input.

    It's difficult [for me] to understand exactly what's possible with my hardware... The documentation that comes with this stuff is more difficult to understand than Chinese Algebra. I'm almost certain I can run two video cards with one display attached to each (without Crossfire). And I'm fairly certain I could just connect both displays to the same video card (saving the other card for another PC).

    But, I really wanted the optimal performance of Crossfire blazing through the dual displays!! Oddly enough, I have not a single high-performance game (Just not my thing). Occasionally, I'll venture off into a game of Hearts or Peggle. Hardly the type of game that would tax the graphics card. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>.

    <img src=/S/whisper.gif border=0 alt=whisper width=29 height=17> I know what you're thinking. So, why do you want all that graphical power?
    Really not sure; I just don't want hardware limitations to be the reason I can't get something done. And I like it when a PC is able to speed along.

    Crossfire with Dual Display

    In a day or two, I will begin assembly of a new PC. My question is in regards to using Crossfire with Dual Displays...

    - I've got a Crossfire-Ready motherboard (ASUS P5K Premium), link
    - I've got two Visiontek HD 2600 PRO 512MB Video Cards, link
    - I've got two ViewSonic VX2235wm (22") LCD Displays, link

    The spec sheets for the displays indicate that the connector type is: Analog/Digital 15-pin mini D-sub/DVI-D

    This will be a Vista-64 rig.

    My intention was to build the PC with Crossfire enabled and ONE display; get that running well; and then introduce the 2nd display.

    Q.
    Am I approaching this correctly?
    Any advice?
    Will dual displays even work with Crossfire?
    Will I need additional adaptors / connectors?

    I am experienced with building PC's. But I've never used two graphics cards or two displays before.

    Any assistance (before I break something!) would be appreciated.

    Thanks,
    - Ricky

    Re: Crossfire with Dual Display

    I would check and make sure that the version of Crossfire is Vista ready, as many programs MUST be updated to a Vista version.

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    Re: Crossfire with Dual Display

    Personally, i don't think you need a justifiable reason to explore new hardware. Whether it is for work or for enjoyment (and god bless if that is one and the same for you) exploring new hardware options is usually a learning experience and sometimes a rewarding experience as well. You should get a modern, high power, graphically rich game and check out the experience. You can run it normally and then switch in the CrossFire capability and literally see a difference. People have made the argument that a better way to proceed is to get a single very high end display adapter, high performance CPU and low latency RAM. I suppose it depends on one's mix of applications.

    CrossFire is a type of parallel processing. Rendering a complex, 3D image that changes quickly is compute intensive and CrossFire (and its predecessors) utilizes multiple graphic processors to work on ONE raster image. The image can be divided in various ways to split the work load (even line odd line, alternating frames, or small rectangular arrays, ......), but each of the video adapter's GPU work simultaneously to complete the required rendering. So that scenario has rendering commands for ONE raster image, TWO graphic processors executing those commands simultaneously and ONE rendered image on ONE monitor . If your 3D application is not demanding enough you may not even notice a difference with crossfire enabled.

    If you are not going to run 3D apps, then you should consider having a CrossFire-less super monitor setup. You have two display adapters each capable of supporting two monitors. A 4-monitor setup would be great fun.
