First of all, thanks so much for developing this amazing program and a cool community.
I'm currently using Open Space to export frames and then converting into video for projecting in a 4k, 2 projector setup.
It seems to me that resolution of the exported frames are limited to my computer screen. If I open a bigger window than my actual screen it's almost impossible to navigate the program.
I was thinking of "simulating" a bigger resolution than my screen with either a virtual display or through Nvidia's DSR, but I've been having mixed results.
Is there a recommended way to setup my project to export very high resolution frames (4k+)?
