Regarding the banding, what puzzles me is that if I play the UHD/HDR test file with the strong banding directly in my TV's media player, from a USB 3 thumb drive, there's no banding issues (it's extremely mild). That's just how it looks with the zidoo, if I use AUTO, YCbCr 444, or YCbCr 420 (which might actually be sending out YCbCr 444), but only if I use 12bit. If I use 10bit with those settings, it's not terrible, but I do have a bit more banding compared to 12bit. That makes no sense, because the file is not 12bit color, it's 10bit. So it should look the same whether Zidoo is set to 10bit or 12bit. But 12bit definitely looks better - as good as when I play it in my TV. So my panel is certainly capable of displaying the file with minimal banding. I just have to set Zidoo to 12bit to get that, and I don't know why 10bit doesn't look just as good. My panel certainly isn't 12bit, so 10bit should be all I need to send. And of course in YCbCr 422 or RGB 444 no deep color setting has any effect - the banding is extremely bad regardless of deep color setting. This was all listed in my post on banding in the 2.0.5 firmware thread.
