Hi,

The HD621 is equipped with 1.3 HDMI chipsets.
This version of HDMI supports 10.2 Gbps bandwidth.
There is no change in the bandwidth limitation with 1.4 version.

Ultra-HD blu-ray are 24 images/s and use a 4:2:0 10bits color subsampling.
With 10.2 Gbps bandwidth, the 1.3 version can handle 4k@30p 4:2:0.

Has someone done some tests with a UHD player and the HD621 to check its compatibility?

Serge.

It doesn’t support HDCP 2.2, hence the 722.


Main system - Sources (Kodi-HTPC, FireTV, Sat) into Trinnov Altitude 32 (8-16) (+Roon), Trinnov Amplitude 8 amp & Vivid Audio (Giya G3, V1.5) and REL Stentor III speakers. Others: F80 + Raspberry Pi and other Pi systems.

Looks like HD Fury might be the key.

Thanks Cliff.
I forgot this @*ù$ protection frown

In this case, a UHD player should downscale the signal to 1080p.

I have read a exemple with a Sony X800 player linked to VPL-HW55 projector through a Marantz 8801.
The signal is downscaled to 1080p 4:4:4 12 bits. And the result seems to be better than a BR disk.

Does the HD621 support this format ?

Serge.

Hi Serge

I’m no expert, but I think you would need more bandwidth than the HD621 could handle for that colour space.

You're rights, Cliff. 4:4:4 is too much for HDMI 1.3
4:2:2 10 or 12 bits is ok.

To give an idea of the percieved gain in resolution when changing the subsampling for the same resolution :

I have checked the outputs of the Panasonic UB700 UHD player.
There are 2 HDMI outputs. One that can be dedicated to the audio and the other for the video only.

I say just about anything...

4:4:4 subsampling it too much for HDMI 1.3 ... for 4k resolution. Not for 1080p wink
HDMI 1.3 is compatible with 4k@30p 4:2:0 but new HDCP version does not make this possible with 1080p projectors.

So 1080p@24 4:4:4 10/12bits is ok for the HD621 cool

I regularly passed 4K/(24|25) from an Amazon Fire TV through my HD621 using an HD Fury Integral.

Haven't tested HDR metadata through it as I didn't have an HDR capable display at the time.

This is really good to know.

Do you know for Apple TV and 4K Box TV (equivalent Sky 4K Box) what resolution we require to have 4K on a TV?

To be honest if the HD Fury resolves the 4K issue of the HD621 that would avoid me having to buy a UHD722.
