4-Monitor Setup for Cockpit Simulator

[Reggod]

Hi, and thanks for taking a look,

My brother is building a cockpit simulator "pod", and I'm helping him with the computer setup. Now I need a little help on one aspect myself. He'll be using Lockheed Martin's Prepar3D Simulator and wants to use a four monitor setup; two for the forward view, two for side windows. From the research I've done, this should be possible, but I need help figuring out what cables or adapters are needed in the first place. He has a desktop PC with a Gigabyte GA-78LMT-USB3 mobo and an AMD Radeon HD 6870 graphics card. Can i support a four monitor view with one or both? Looking at the back of the PC, I see 2 DVI, 1 DP, and 1 HDMI port on the graphics card, and 1 HDMI, 1 VGA, and 1 DVI, on the mobo. I currently only have a DVI and VGA cable on hand, and I'd like to figure out exactly what I need before heading off to the store. Thanks for reading.

Here are the system specs - https://www.prepar3d.com/system-requirements/

I think you are going to need a better GPU.

I'd say you would want to use all ports from the graphics card. So depending on what monitors you have you will have to adapt from your DVI, DP and HDMI, according to the monitor.

Though I feel with running this Simulator in on 4 monitors will run terribly if you can even get it to run at all. Minimum amount of V-Ram required depending on the version is 1GB (the Graphics Card only has 1GB V-Ram). Also Depending on what CPU you will struggle to run this on 4 monitors. I reckon you will probably something like a GTX 1080 paired with a i5 or a newer Ryzen CPU.

Here is a link to their forum were someone runs Sims with 4 monitors, though he does have a issue with it crashing in Prepar3D when using 4 monitors but his PC is pretty Beefy with a nice OC on the CPU.

Thanks for the advice. I doubt the CPU will be a problem. Its an AMD FX 8320 8 core processor @ 3.50 GHZ. (I could OC, but don't think it necessary.) The GPU, however, I'd appreciate some more help on. I was thinking perhaps I should run two AMD GPUs in crossfire, although I've never used it before. Is the technology outdated? I think I remember reading that Nvidia GPUs can support a similar set up and that they're less prone to stuttering perhaps. With that info, ya' think a simple GPU upgrade would be enough?
