Rocketfish HDR-capable HDMI Splitter

I recently bought a Rocketfish RF-G1603 2-port HDMI splitter with HDR from Best Buy.

I have 1 output from my Denon AVR that goes into this, and this outputs to both my Samsung Q70R TV and a Dreamscreen 4k ambient lighting kit.

In isolation, both devices (Dreamscreen and Samsung TV) will accept a 4k signal with HDR from the AVR. However, when I route the signals through the Rocketfish unit, it will accept 4k but not with HDR. I have tested with both a PS4 Pro and Xbox One X as the input device and it is the same in both cases.

When I use the Dreamscreen 4k as the passthrough, it creates green "noise" on the signal which makes in unusable.

Does anyone have any ideas on either 1) how to correct the Rocketfish signal to pass through HDR, or 2) have suggestions for a different splitter that would do the trick.

Thanks

Hi Adams


Since no one have replied yet, here you go:


Your DS unit is HDR, while your Samsung Q70R is HDR10+, my guess is that the rocket fish is unable to isolate HDR10+ from edid signaling as it is not located where usual HDR10 signaling is located, so it fails to mix capabilities (assuming it mix anything in the first place)
Eventually using an EDID manager that copy your display EDID and insert it between Rocket fish output and your DS unit input would help. Not guaranteed since the splitter could still fail to retrieve HDR10+.
Doing the same using DS unit EDID and placing EDID manager between rocketfish output and Samsung QR70 could help too but you would then limit your Samsung to what DS is capable of... not optimal choice.


We do have solution that will work for you, Vertex2 can solve the issue or you can even drop DS if you go with Diva and our ambient light solution (which truly support HDR)

Maestro: 4I/4O +4K HDR over HDBT +Autoswitch any sources +HDMI/ARC/eARC sound to AVR input +webserver. [Won Best Product Award]
Diva: 4I/3O +Ambient Light +Lag Tester +4K HDR > 1080p SDR +HDMI/ARC/eARC sound to AVR input +autoswitch +webserver.
Vertex2: 4I/3O +Autoswitch any sources +HDMI/ARC/eARC sound to AVR input +webserver.
