[vdr] Questions about good hardware to view VDR 4K

Hi,

I am looking for an ATX motherboard with PCI and PCIE slots, for using with new VDR 4K (PCI S2-3200+CI and PCIE Hauppauge quad), and ASTERISK (PCI Digium FXO/FXS card).

At the beginning, I was thinking about an Intel 1151 socket (for best vaapi support), like this one (*):

Unfortunately, I noticed HDMI is v1.4, with 4k@24Hz only !

I am afraid that I need to add a PCI-E video card to achieve 4k@60Hz.

Is it correct ? If so, I have two questions : 1) could you advice about fanless + VAAPI compatible product ? 2) any feedback about best plateform/chipset : AMD vs Intel ?

Thanks a lot. Karim

(*) using with low TDP quad core CPU, for example i3-8100T.
