Thanks for the response.

Late last night I googled a bit and what I need is a HDMI splitter with scaling option.
I found a interested product that can send passthrough 4k signal on one output and 1080P out on the other output to the HD621. It will process the lossless formats on each output at the same time.

CYP SY-4KS-4K22

I will do some more research about this device later wink
