Well, I was hoping for a firmware bug considering that your previous test pattern appeared fine

Apparently 4:2:0 is really fubar: http://www.ntt-electronics.com/en/pr...deo-codec.html

I can see how 4:4:4 might be considered overkill for displaying 4:2:0 YV12 sources and why some(many?) TV sets save money by processing in 4:2:2: http://www.5dfilmmaking.com/tut_444.htm

PS: OK, case closed: whatever I do in "movie" mode, red blue and magenta never look as sharp as the others.

Actually, the darn thing can go 4:4:4(even with PIP enabled) if I rename the input to "PC" but then no more BFI & REC.709 gamut..
