The external framebuffer uses YUY2 image format. Individual pixels have their own luminance (Y) values but each pair of pixels share chroma (U/V) values.

Oh, I see, so that explains the repetition of luminance values. Does that also mean that two adjacent pixels cannot be of two different colors? Can the GX subsystem overcome this limitation? It seems to me that commercial games (and other homebrews) can manage single pixels in the "normal" way, am I wrong?

Thanks for your reply.

They have the same chroma values but their luminance is different so they're not the exact same colors. A regular standard definition TV can't really get better picture quality due to the max sampling frequency of the chroma signal.
