I did some tests with Sony Camp 4k HDR/ NO HDR and i made a little video : https://1fichier.com/?4qqv5z40s4

the boxes (shield TV and Q10 pro) are directly connected to my tv (hdmi enhanced)


Q10 pro:

Demo 4K HDR

Video output SDR : no problem, the color gradation is smooth

Video output HDR10/AUTO : the sky seems to be like 8bit gradient/gradient dithering, the High Dynamic Range works well

Demo 4K

Video output SDR : no problem, the color gradation is smooth

Video output HDR10 : no problem the color gradation is smooth



Nvidia Shield TV

Demo 4K HDR

it is less visible but there is the same problem. ( HDMKV if you can try it too with your Vizio TV 4K)

Demo 4K

no problem the color gradation is smooth

--------------------------

CONCLUSION :

i'm not an expert but i think the 4.2.0 10bit not work at all with the Q10 pro, it goes back everytime to 8bit with SDR, HDR10 and auto.


with the internal player Sony, Sony Camp 4K HDR works perfectly.


with another demo 4K HDR ( life of pi, exodus, etc...), i do not have this problem.


have nice evening
