Using 9 1080x1920 monitors on a single computer

Post by papafox »

I've previously used 3 computers to run 9 1920x1080 HD TVs in portrait mode with Prepar3d using Wideview software with good results, but with the possibility of running 3 Nvidoa 1080s in a single computer, it'd sure be nice to switch to a single-computer operation. My guess is that all the views would lug any CPU down to the point that this approach would be undesirable, but I'm seeking opinions of individuals who might think otherwise. CPUs exist with more than 4 cores, but perhaps there's no way to spread the work over the various cores efficiently at this point and with any CPU the 9 screens would run slowly. I hope I'm wrong. Anyone want to chime in?

Three monitors will have 50/60% fps of 1 monitor.
Nine will leave you with 5-7 fps if you are lucky...

One way I found to minimize the frame rate loss with multiple monitors was to use Nvidia's surround technology and designate three monitors as a single monitor as far as Prepar3d was concerned. The resulting 3240x1920 view was a reasonable shape for Prepar3d to render. The problem is that Nvidia probably doesn't offer the ability to set up three (or even two) surround monitors on the same computer. If I am mistaken here, please correct me.

Perhaps one solution would be to use devices such as Matrox triplehead2go in order to render three displays instead of nine (but 9 TVs actually are being used). With a fast CPU and 3 Nvidia 1080s or even 1070s, the frame rate might be acceptable.

Obviously, the more distinct views set up, the slower the frame rate. What else is important as far as Prepar3d's speed is concerned? Resolution is more an issue of the graphics card. I suspect a wider angle view would require more calculations by Prepar3d on the CPU. The trick is to understand specifically what causes the bottlenecks with massively-wide outside views and work within those bottlenecks to maximize performance.

Dave, Thanks much for the link, it is useful.

As for Matrox triplehead2go, it works at 50 hz and that doesn't work so well with most LED TVs, I think.

With Nvidia surround now supporting up to 5 monitors, I'm down from 3 to 2 computers, so that's a start. Looking for an elegant solution still for moving down to one computer with 9 displays.
