Triple Monitor Support 2024

[Tree_Beard]

I just purchased a set of three 32" 1440p curved Gigabyte monitors primarily for sim racing. Since I now have them set up in a rig, I was also curious about DCS. After some brief research, it looks like most of the info online about using triples for DCS is years old at this point, so I am wondering what the state of triple monitor support in 2024 is? 

Right now, using Nvidia surround to generate a custom resolution, I can get a decent picture in DCS, but there is definitely still some noticeable geometric distortion with the image on the side monitors. I don't immediately see many settings I can tweak within DCS to adjust the picture, though. 

Does anyone else here run triples and, if so, what settings are you working with to get a good, non-distorted image?

I don't think there is a vibrant and engaged community of triple users in DCS and not sure why? 

I run the same curved 32s and it was outstanding for sim racing with a lot of user contribution. 

 

It doesn't seem to be a viable option for DCS and VR doesn't appeal to me personally

Bezels. ¿How solve it?

Couple of questions---hopefully I can help.  What resolution are your 32" monitors? Are you running nvidia GPU?  

I'm running triple 32 1440p monitors on nvidia Surround at 7770x1440 using the bezel correction tool in nvidia Control Panel.  If your monitors are 1440p and you set up surround, maybe I can share a couple of my ini files to get you fixed up.

Ok.  When I fiddled with multiple viewports using the 3 monitor setting, I had some luck with the attached lua.  You might compare it to your 3cameras.lua, or back yours up and replace it with this one and see if it helps.  

Months ago when I experimented, I found using Surround and a single monitor setting to be preferable, as it had better performance, was easy to set up, and maintained usable view at varied FoV's.  I run my FoV in Surround at 120, zooming out to max 140 from time to time.  120 is pretty zoomed in, but to me it presents a near 1:1 size presentation of the cockpit sitting about 24-30 inches from the screen.  Also, any fisheye/warping is eliminated at 120 FoV.  I'm not sure what FoV number works best on the 3cameras setting, as the number ranges differently in Surround.
