@Asmodian: Neither 4:2:2 or 4:4:4 appear when displaying chromares.png (nvidia set to 1080p, RGB at any bitdepth). There is some slight horizontal lines where 4:2:2 would appear.
@Warner306: I presume you are refering to the discussion over at AVS with madshi on the
Madvr HDR to SDR mapping thread?
