Regarding the PQ of the wetek core 4K it didnt perform better than the Nvidia shield in the spears & munsil test.

Its the same test Done in GeForce forums started by @wesk05

1- Missing white line (centered screen)
2- the RGB to YCbCr conversions need to improve the colors are fading
3- Red, white and blue are clipping
4- bands are BAD
5- chroma range check are BAD

i've only tested 5 android boxes but they all output an RGB signal which is for computer, phones etc.

YCbCr is needed for tv's but none of these devices including the Shield do it.

the same video file looks much better on an old device like a ps3 because ps3 has option for YCbCr
