Hey RTH,Sorry for the delayed reply it is hectic right now. Ryan, I am going to check email after this...RTH,You are correct, I just run them as separate video cards and never enable SLI. Each monitor you have enabled gets assigned an ID 8800GTX 0,1,2 within FS and you get your 8800 GTX cards pulling the full load. The biggest benefit to this is I open a separate 3-d spot view of the A/C on monitor 2 in a small window to simulate a Tail Camera. Try running Full VC at 1920*1200, Radio, CDU and Pedestal Panels with a separate 3-D spot view on window 2 AND an overhead on monitor 3 all full screen on anything but dual 8800 GTX and see what happens. With my setup I get 22 FPS locked at 24 at ImagineSim KEWR with all sliders maxed, AI at 70% AND MIP MAPPING Added to all of my DXT textures in any plane out there including the PSS 757. That pretty much says it all :) I had dual 7800 GTX, dual 7900 GTX a 7950 GTX and now the Dual 8800 and there is NO comparison.Funny that all of those new "lighting features" such as dynamic wing shine etc that FSX boasts are available in FS9 if your video card supports it. You should see the shine/shadowing effects it is mind blowing. Go down the road you are traveling and you will not look back. For the first time I don't care about new hardware because I can throw anything I want at my FS9 system now. It is a wonderful wonderful feeling...Good luck,-PaulPrimary RigLiquid CooledIntel C2D E6600 @3.2 gigsAsus P5N32SLI-Plus2 gigs Corsair XMS PC6400 4 4 4 12 @810Dual OC'd XFX 8800GTX @ 2 gigs24 inch Widescreen LCD 16XAA/16XAFDual 19 inch LCD'sRaid-0+1PCPower and Cooling 1k Quad SLIhttp://home.comcast.net/~psolk/3monitorsa.htmlBackup RigAMD 4000 San Diego @ 2.72 Gigs Kingston Corsair XMS CL2XFX 7900 GTX Raid-0

Thanks Paul:I can't wait until Thur. when my new second card arrives. Last one came from New Jersey in two days, but this one is from Calif. by Mule Train. Unusual for Newegg, but there may be a run on these cards now.Tomorrow, I will get the 21" Samsung out of storage and get it set up for the 4th monitor to go along with the three presently on my desk. Need to do a bit of rearrangement. It was a bit fuzzy on text, so I replaced it, but should be good for the larger displays. If I can find anywhere within 100 miles or so that works on the things, I will get it fixed, but here in SE WV it is hard to find reliable service for such things anywhere within reach. Shipping any distance negates repair at a service center due to shipping cost. May as well buy a new unit. How do you like your "24 inch Widescreen LCD 16XAA/16XAF" and what make and model is it?Thanks again:RTH

Hello again Paul:I am afraid I am going to have to tuck my tail between my legs and ask for some help.How did you get your rig 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 8800GTX 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.I sure would appreciate any suggestions.Thanks:RTH

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

Hello again:IT WORKS!!!!!I am sure everyone would be interested to hear a more simple scenario if you have one, but this is how I finally got all four monitors to display. Any ideas on the error message would be welcome as well.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

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
