+
+@NOTimothyLottes i am not quite sure what do you mean by subpixel scan? do you override the normal (refresh) scanout process?
+
+**2/**
+
+@tomcr2100 It's like "clear-type" font rendering where if you know the LCD sub-pixel configuration for the RGB components of a pixel, you can do a much better job of computing and outputing the value at the specific RGB sub-pixel element. So i'm doing this for CRT-like emulation on the Deck
+
+**3/**
+
+@NOTimothyLottes just curious, i started doing something similar, but this year i have focused more on rest&recover. i went with a trilinear style aperture grill approximation, and just allow prim components to leak into the two others.

 The non-subpix scan has 1-pixel separation of RGB (intentional bad convergence) to help hide scaling. The subpix scan uses 1/3-pixel separation (less visible misaligned convergence). Pixel as in output pixel.

 The subpix version is definitely better. Because of the almost 3x doubling of scanline width detail, it just perceptually feels a lot cleaner and easier to reconstruct in the mind.
