Has anyone tried Unity on this monitor?
Is the resolution (3840 x 1080) supported by Unity games? I suppose this depends on SO and Direct X - GL, but I’m not sure.
In general unity build will support any resolution that the GPU can output.
That does not means that the games are optimized for that resolution / aspect ratio.
I had my share of problems with a 1X1080p setup (5760X1080).
