Hello and ty for the reply.
Unfortunately the 4th display is also in portrait mode and as such, no bueno on using it to stream as its 1200x1920.
The developer of CRU told me something along the lines of getting 1920x1080 to show up in the games list (in order to set it as a windowed option) requires adding a resolution to each display independently that adds up to 1920x1080 aka 640x360 or some such.
I couldnt get it to work however. I know surround is niche, but hopefully not so niche that someone doesnt come along with an answer at some point
Ive dealt this long, I'll continue doing so with hope lol.
I thoroughly regret going with such an ostentatious build at this point. Cool factor was a reasonable motivator at a younger age but now, I just want everything to work without trouble lol.
