I haven't seen anyone else with this issue. I'm running the following configuration:Asus P5N32-SLI Premium MoboWindows Vista Basic 64-BitIntel Core 2 Duo E66008GB DDR2-800 Memory(3) GeForce 7950 512MB Graphics CardsWestern Digital Raptor (OS)Hitachi Deskstar T7K500 (FSX)3 x Sony 17" LCD's2 x Dell 19" Widescreen LCD'sI'm running 5 monitors on the 3 video cards. The system boots fine and the multimonitor config is setup perfectly in windows. When I fire up 4 of the monitors in FSX everything runs beautifully. It doesn't matter the combination of monitors (Dell, Sony) or even if I have the 4 hooked up to 3 different graphics cards. It runs rock stable.As soon as I add the 5th monitor, FSX won't start. Sometimes I get fatal error messages with different dll's being targeted each time. Other times the program will appear to load and then hard crash to the desktop with no message. Does ANYBODY know why it is so hard to run 5 monitors in FSX? I have done it successfully with 5 IDENTICAL monitors. Is this the only option? Please help!!

I think your the 1st to try :)

I've run 5 monitors successfully from 2 graphics card using a TH2Go for 3 monitors off one card and then 2 monitors off the second card. This is in XP Pro. Never tried 3 cards, nor tried 5 monitors under Vista, so can't help other than to suggest using a TH2Go.RegardsJim

Please help!!There is one setup here with twelve monitors ... http://www.wideview.it/wideview.htmI would rather have one biggie like this one ... http://photos1.blogger.com/img/85/3279/640...dpi_1271356.jpg

The specs aren't the most powerful. But I **HAVE RAN** 5 identical 17" LCD's on the same system with Win XP SP2 and 2GB of RAM successfully. (I eventually got an OOM message). I figured an additional 6GB of RAM and 64-Bit Windows would take care of the OOM message. In Vista 4 monitors runs FLAWLESSLY. (Any combo) I just can't add the fifth. Any other suggestions?In the meantime I'll try to dig up the 2 old monitors so I could run the 5 identical 17" Sony's in Vista. In theory this **should** work.

Hi, I never have run 5 monitors, 4 yes, on two cards, what interests me is , how do you run 3 cards on a SLI board?

The ASUS board I have has 3 PCI-E slots. I run the 3 cards in non-SLI mode. Like I mentioned the OS is rock stable as do other apps. It is just when I launch FSX it crashes.

Has nobody run more than 4 monitors on one system? As I've said I have acheived this in Windows XP 32-bit bit got OOM messages after a while. Can anyone help me figure out why I can't run 5 monitors in Vista 64-Bit? I'd really appreciate the help

I'm having similiar problems trying to run 3 monitors using 2 video cards. Vista runs them fine but FSX crashes on load. However, 2 monitors any combination works. You said you can get 4 working fine...how about 3...can you get three to work...if not maybe buy a 6th monitor. I now that's not the solution you are looking for...because I'm not trying to buy a 4th monitor...just curious.-Ray

Just to update everybody, I tried every possible configuration and had no success. I wound up building a second (similar) tower and networking the systems through WideView & WideTraffic. I'm loving the setup right now. I've determined Nvidia's DualView function is basically limited to 2 physical GPU's in one system. Once DualView is enabled for the third card, games CTD (most of the time without error messages). If Dualview is used on 2 of the GPU's and I CLONE the 3rd GPU's display, there are ZERO problems. Oh well, maybe in the future Nvidia will recognize the function and ability of MORE THAN 2 GPU's in one system outside of SLI-Mode.For now, it's happy flying through WideView!
