I see posts of folks that are running more than two monitors with 8800GTX cards. I am afraid I am going to have to tuck my tail between my legs and ask for some help from anyone having success with such a configuration.How do you get a system to recognize the second 8800GTX card? I am running in the non SLI mode and thus far have found no way to get recognition by Windows that I have the second card, along with the third and fourth monitors. I have removed the drivers, cleaned house, reinstalled the latest drivers, and switched cards. The two monitors off of the primary card work fine, but I never see anything off of the second card. The fan is running and it is slightly warm with no error messages. I show only one 8800GTX in the System?Device Manager?Hardware?display adapters. I sure would appreciate any suggestions.Thanks:RTHASUS P5N-E-SLI MotherboardIntel E6600 Core2 Duo CPUZalman CNPS7700-CU RT CPU Fam4 GB KST DII800 MemoryWinXP ProNVIDIA VCG8800GTX 768MB Primary Video Graphics Card21

A little progress but no bannana yet:I have a card integral to my motherboard which can be put in either the single video card, or dual video card configuration. I apparently did not have it seated well enough in the dual position.I now have two 8800GTX display adapters shown in my system/hardware/device manager. Unfortunately, one has the exclaimation mark by it indicating a fault. So far, I have not been able to get the drivers recognized by this card.One more thing to try, that worked when trying to implement an old PCI card as a secondary. I will let you know whether it worked or not.To be continued:RTH

When you swapped over the Graphics cards was it the same card that was the problem or the same slot?Jim

Hello Jim:Either card worked in the primary slot. Neither card worked in the secondary slot. This was unfortunately due to the fact that I did not have the MB configuration card seated properly (single card or dual card position option).See my root reply to my post. I got it working!Thank you kindly for the help.RTH

IT WORKS!!!!!I am sure someone else with more savy may be able to come up with a method that is less work, but this is what worked for me. With the exception of having to run setup toward the end, the same scenario worked for me for some weeks with an old PCI card, but failed a few days ago. This is what worked for me.1. Remove the NVADIA drivers in your Windows Add/Remove options.2. Shutdown the computer3. Remove your Primary 8800GTX card (Primary slot).4. Install your secondary 8800 GTX Video card (Secondary slot).5. Disconnect from the internet. (may or may not be necessary).6. Restart the computer in safe mode.7. Run Drive Cleaner for all NVADIA Display drivers8. Check that the NVIDIA directory on the "C" drive is gone.9. Check in device mgr. that the 8800GTX is gone.10. Restart the computer, cancel new hardware found upon bootup.11. Install the latest NVIDIA drivers for the 8800GTX card.12. Set up your adapter and monitors to desired settings.13. Shutdown the computer.14. Remove the secondary 8800GTX card.15. Install the primary 8800GTX card.16. Restart the computer, cancel new hardware found upon bootup.17. Install the drivers, but RENAME THE INSTALLATION FOLDER during the installation process. DO NOT LET IT INSTALL IN YOUR PREVIOUSLY ORIGINATED FOLDER FOR THE SECONDARY CARD. If you do, it will overwrite the format to your primary card's monitors.18. Set up your adapter and monitors to desired settings.19. Shutdown the computer20. Reinstall your secondary 8800GTX card.21. Restart the computer.22. Go to your NVIDIA folder on the "C" drive and run the setup.exe file. The third and fourth monitors will then kick in.One glitch that I don't know how to get rid of, nor do I have any idea that it has any effect on anything: The NVIDIA Control Panel works fine in spite of this error message. Upon bootup, the old MS "Send error report" and "Don't Send" appears with the following dialogue: "NVIDIA Driver helper service, version 158.22 has encountered a problem and needs to close. We are sorry for the inconvenience." I assume this is a conflict of some kind due to the two separate folders with the same drivers, but it is a bit over my head.Now I have four monitors. WoooPeeee!Respectfully:RTH

ON HOLD!I lost my no. 3 and 4 Monitor and have an explanation mark by the second 8800GTX card in Device MGR.This is going to deserve another chapter (at least)Sorry!RTH

I have an XFX service center just down the road. My poor ol 6600GT is always on fire, so I'm down there quite a bit. I'm not entirely sold on this triple-head-to-go span method and have been thinking about using FSX's view sync function over 4 monitors (you too?).Sooo, last time I was down there (what a wonderland that shop is!), I asked the techs about this very issue. One actually had one going at home. He said it was entirely do-able, but said it was a "click around till it works" drill. Ugh. I need something more definitive too. But then he said something very interesting. He said that his home system set-up with an 8800GTX PCIe and a cheapo 7300 in the second slot. He said this 4 monitor scheme would work equally well with a second Vcard in one of the plain old (antique) PCI slots. I said that I was running sims and needed big horse power to all 4 monitors. He said "me too!" World of Warcraft and an occasional flight in LOMAC were his games. He said 2 big cards will make no difference for a 4 monitor setup. He went on to explain the Nvidia software will recognize that there are two cards installed. You then set-up the big card (in the setup screens) as your "Primary." The primary card does ALL the video processing. He said the second card will do NO - zero - video processing. It just provides a second set of VGA/DVI outputs. He said that if I wanted to drive 4 monitors, get a big 8800 and a cheapo 7300 as the second card. A second 8800 would make no difference. Who woulda guessed?At this point, your best bet might be to SLI the 88s and set "it" to primary. Then get a 50 buck PCI something-or-other Vcard to provide outputs for the 3rd and 4th monitors. I'm afraid otherwise that second 88 is gonna be wasted.

FORGET everything else I have said!Unfortunately, finding information for configuring has been futile. Non-SLI Multiple Monitors seems to be totally ignored by NVIDIA (Three are four anywhere I could find including by a Google Search) In any case it sure was difficult for me to locate. Therefore, the trial and error monkey and bannana routine is the only way I know to find the solution.In my ignorance, I did not realize that the SLI jumper was required EVEN NOT IN SLI MODE!. I installed it and everything fell in place with no error windows, and a fruitful four monitor setup.The old standard routine for driver installation worked like a charm with both 8800GTX cards installed in my computer.1. Remove the NVIDIA graphics drivers with the Windows ADD/Remove provisions.2. Disconnect the internet connection2. Restart the computer in save mode canceling the found new hardware notifications (two).3. Run Drive cleaner (Particularly NVIDIA items).4. Restart the computer canceling the found new hardware notifications.5. Install the latest NVIDIA drivers. Yesterday, May 17, 2007 new version 158.22 drivers were put on the NVIDA download site. It is stated that they are WHQL certified, but when installed, the setup notification says that they still ARE NOT. I don't know if there is any difference in them from the previous 158.22 drivers uploaded a few weeks ago or not, but both seem to work well on my system.5. Restart the computer.6. Open the NVIDIA Control Panel and select SET SLI Configuration under the 3d settings.7. If you want multiple monitors select Do not use SLI technology.8. Open your display settings, enable all monitors, and setup your desired resolutions, refresh rates, and positions.So far, the above has resulted in beautiful results with no glitches. Along with the new SP1 provisions, FSX is doing great. For the first time I can even fly the Capt.Sim 757 in FSX with no problemsGood luck to all, and I apologize for such a lengthy, confusing, and frustrating ordeal.Respectfully:RTH

Sounds exciting, just followed your posts!I am running 3 TFT's on 2 cards. They are all recognized. However, I haven't found a way to have FS spanned on 3 monitors. As it seems by now, I can only span per graphic card. Do you span in 3d or simply drag the views to the next monitor?Thank you very much, Sam

Sam,I've not found a way of spanning across 2 separate cards. Like you say..you have to go into Windowed Mode and drag the window across the 3 monitors. Alternatively get a Matrox TH2Go and span 3 monitors that way.. However your resolution will be limited to 3x1280x1024 which limits you to 19" monitors (native resolution).RegardsJim

Now the trick is (once you get those 3 or 4 monitors monitors going), what are you going to do with all those glowing screens. I see 3 possibilities.1) The first is to "triple head to go" three of them and use the 4th for general entertainment during a long flight. The TH2G scheme just zooms back as far as possible and spans that single screen across 3 monitors. Works great, but what's the big deal there? Should'nt we be able to do this ourselves? Let's see. 2) Fire up a V-cockpit then set the screen to Windowed Mode. Now simply try dragging the screen across several monitors. If it doesn't work, try a demo of this little program: http://realtimesoft.com/ultramon/It works for me . . . well almost anyway (Soooo close!). I have a dual (19") monitor setup off a single Vcard. I have the video properties set to span mode. With FS9 and FSX in a windowed mode, I can drag a V-cockpit window across my 2 monitors. The FS9 / FSX window entirely fills both monitors, but there is a problem. The image initially fills both windows, but then snaps back to fill approximately 1/2 of the total dual monitor area. The image remains perfect quality, it's the entire Vcockpit, but always snaps back so it ends up filling the first monitor and then just hanging over a bit onto the 2 monitor. The image does not seem monitor dependent. The monitors seem to be trying to act like a single, big 2560/1080 monitor. It almost seems like I'm just running out of V-gas. The other half window (4/5ths of the 2nd monitor) is just plain ol' black. I have an 'ittle-bitty 6600 and I hope this is just attempting a capability my card cannot handle. I'd be interested to see if it might work with a modern Vcard. If it will work with 2 monitors, why not 4? The XFX tech says the video properties screens will allow 3 or 4 (or 6 or 8) monitors to be spanned just like 2 (see my previous post above). I'm hoping that if a Vcard would handle these bigger resolutions, that THTG money might be better spent on . . . well, anything! 3) The third way comes right from our old friend, MSFS FSX MVP, Taildragger: "BTW, here's a tidbit you can try that doesn't even require multiple monitors:1. Go to the keyboard assignment dialog and look for "View - link all (toggle)".2. Assign this to a key combo (I use CTRL+SHIFT+/).3. Load a flight.4. Select the VC view.5. Open a new VC view (from the menu: Views | New View | Cockpit | Virtual Cockpit).6. Use your keyboard/hat switch to pan the new view to look right.7. Press the keys you defined in step 2.8. Repeat steps 5. 6 and 7 to create additional views 9. Drag new view over to appropriate monitor. 10. Pan around.You can optionally repeat steps 5 and 6 and pan in different directions. To revert to normal mode press the key combo again.I'll leave it to you to discover what this can be used for.TaildraggerGet the inside scoop of Flight Simulator X:http://blogs.msdn.com/tdragger/"This is an old post from taildragger during the runup to release. It works exactly as advertised. You can setup 100 monitors like this, if you have 'em. The only real problem is that the alignment does not work too well. I need to rotate screens to get them right . . . but it's the only thing that works on my system. Also, it only works for FSX because FS9 does not have the "View - link all (toggle)" function. That little "Ultramon" might be the trick with method 2. Maybe someone one of those fancy 8800s can give it a try for us.
