4K on Dreambox One

nicoonline · 27. Oktober 2019, 18:13

Hello,

I tried to configure the video mode to 2160p (4K) on my dreambox one. It's working when connected on my LG TV.
No image when connecting on my 4K Yamaha amplifier.
Any ideas why i get a black screen ? (audio is working). The amplifier is 4K passthrough.

Please set at the LG TV set the HDMI input "HDMI ULTRA DEEP Color" to "on". The HDMI cable should support HDMI 2.
(The configuration at my LG OLED TV).
What Yamaha amp do you use?

HDMI Ultra deep : ON
HDMI Cable : OK
Yamaha RX3060 4K mode "1"

I found the issue. Yamaha doesn't support 4K content @50H/60Hz
Working when i set the 4K @30Hz.

The same problem with my Marantz 7002.The Marantz supports only HDMI 1.4. I´ve connected my dreambox directly with my LG OLED TV and use the ARC-optionbetween LG and Marantz for the sound. That works really fine.

Ok, but the 3060 supports 4K/60p, 4:4:4. (3060 from the year 2016). :denk:

yep exactly so what is the issue ?

May be, that you need Yamaha support!? Could be a bug in the Yamaha firmware?

Is the cable HDMI 2.0 certified?
