Is it possible for Nanodlp to use the three subpixels per pixel of the BOE 5.5" 4k Monochrome VS055QUB-NH1-DQP0 LCD to improve the resolution (in one direction).
The Longer 4k seems to use the same lcd but it can use the subpixels as pixels.
I guess you'd have to set the RGB value of the pixel to match what you wanted the subpixels to be?

Each pixel usually 3 separate RGB color pixels. Which for mono it is completely different as each pixel same gray color so for each pixel you have GGG.
So you already utilize all of them, it is base idea of mono.

At least some of the mono lcd screens have just had one subpixel per pixel.
I was thinking the RGB screens only worked through the blue channel and so it didn't matter what the other two were set to?
So this mono screen the slicer can set the subpixels GGG to different shades of grey for instance if doing anti aliasing?

No all three color channels being used on both RGB and GGG. But on RGB all three, so called subpixels, work together to generate gray, it depends on light spectrum your resin use but usually majority of power to cure single pixel come from a one of the subpixels. (Daylight resins are exception)
For GGG, each subpixel is equal to a full pixel as all being controlled separately at least on driver level. I have not seen one but if in reality mono display's driver really could drive each channel separately and RGB filter got removed, horizontally quality could be improved. It is easy to confirm check slicer images for such display, outlines should be in R or B depend if you check left or right side of the object outline.
