Thank you for this link! It covered a lot of what I figured out after a lot of trial and error and them some. It could have saved me a lot of time had I known about it
I’m still thinking about the 2 pixel wide triad, but if anything, I wanted to mention that my shader also has an option to invert the triads (BGR) which doesn’t increase the dpi, obviously, but this configuration packs the phosphors tighter and leaves GBRG free between the triads to better simulate the vertical section of the slot mask
