With the new Nvidia 680 you no longer need an extra video card to output to 3 or more LCDs/Projectors.

 

This negates the need for the Matrox Triple Head to Go.

 

Has anyone with the 680 tried Nvidia Surround mode with FSX?

Yes, many users within this forum are running a single GTX680 with 3 monitors. Just be warned, you will see a large drop in performance from 3 displays.

What if you are running 2 4GB cards in SLI?

Yes. See system specs

I just recevied mu GTX 680 today with a new Jetline PC. In a 3-monitor Asus 21.5 in setup, I have two monitors working with DVI. The third is with HDMI; that is HDMI from the card to HDMI to the monitor. The monitor conitinues to shutdown with a "VGA NO SIGNAL" warning. I know I'm missing something, but don't what. THe PC shipped with very little documentation.

 

Any assistance is very much appreciated.

IIRC, you must have 2 DVIs and 1 Displayport being used off of the card. I may be wrong though...

It has 2DVI + 1 Display Port + 1 HDMI. I cant say Ive tried the HDMI on mine but presumably you have to activate using the driver.

Is the performance with 3x output with the 680 not as comparable as using th2go?

It's comparable because either way, you will be pumping mad pixels. What native resolutions are your monitors/projectors? Having used both options myself, I must say that nVidia Surround runs circles around TH2GO Digital. The bezel management on Surround is much better because you get to still use the entire screen on the 2 corner monitors.

 

With TH2GO, the bezel is compensated for by scrolling or shifting the screen right on the left monitor and left on the right monitor, which leaves a large vertical black bar on the edges of the outer monitors. This does not happen with Surround at the expense of more pixels but with the 680, the trade off is well worth it.

 

I was running Surround at 6000ish x 1200 on three 24" Dell monitors and it was awesome. At such higher resolutions, you can lower AA and you can gain back the FPS lost to running a higher resolution without affecting much IQ.

 

I was using both DVI ports and I had a HDMI -> DVI video cable connected to the HDMI port. Never tried the DisplayPort.

 

I have 4 monitors.

 

3 X 24" (Dell 1405FPW) + 19" Touch screen in surround.

 

I am using 2 X DVI + 1 HDMI->DVI ($10 cable) and the surround works fine. I have a passive DP--> VGA (The 15 pin analog thingi) for the 4th Touchscreen

 

For the three monitor surround, all three have to be identical or very similar monitors.

"VGA NO SIGNAL" Thats your answer ..right there.

 

I suspect that your third monitor you are not selecting the source properly. Its on VGA and you have not connected a VGA source to the monitor. , You have HDMI as the source. Just change the source on the monitor to HDMI or DVI

Thanks very much; I have fixed that problem and now have all three monitors up and running. However, I still can't run FSX across the three screens. When I go to FSX Graphic Display, the highest resolution I'm able to select os 1920 X 1080 X 32. Further in Windows 7, on the desktop the bottom task bar is only the center screen so I don't tthink things are right.. I am able to drag items across screens. Basically, I don't get it and think I'm missing something.

 

Thanks in advance for any help.

Go to the nVidia control panel>configure surround, PhysX>check configure displays with surround>click configure button.

 

That should work.

Will possibly try with 3 projectors later down the line. Bezels shouldn't be a problem and planning to use edge blend software. Thats good to hear performance is similar to th2go. That can lead to considerable saving.

So what was the solution to the initial problem?
