Dear all,

i could double check now with additional test material:

www.pc-magazin.de/filedownload/archives/118526796/uhd-hdr-test-v11.zip

So i checked now for an mp4, mkv and ts.

All the content is providing the strange distored pictures i added to the topic attachment. Unfortunately i got no comments on my post, even not from futeko. It would be great if could receive some feedbacks.

If additional infos are needed - just let me know... Perhaps something to my hardware, currently i am using:

Himedia Q10pro with Android 5 and current firmware
AVR Marantz SR7010
Inakustik 4k certified cables 1,5 m
Beamer Epson TW9300W

4k material is displayed without any issue, just when it comes to HDR the strange distortion is shown.

Best regards, Holger

I've never seen distortion like that from Q5/Q10 Pro, and the lack of replies would indicate other haven't either.

If it's happening only with HDR material then I think there's something wrong with receiver / projector settings.

On the Q10 Pro you could also try changing Settings - More - Advanced options - Deep color space & HDMI deep color.

The problem appears to be that your receiver/projector don't understand the HDR signal coming from the Q10 Pro.

I have tested both of the files you provided also by using a Q10 Media Pro and Marantz NR1607. I have no issues to report.
The TV that is used is a Samsung JS9000.
