HDMI optional port..

[Stevo68]

Help! I have an HP Prodesk 400 G6 small form factor and need to find the optional hdmi part. I have tried to contact HP but with no success.

I need the part number and or if I need the cable number two, can or does anyone have any idea?

there are various revisions of the flex I/O boards and they are not usually interchangeable the OP's system requires a v2 flex board

looking closely at the components on each boards picture, they appear to be slightly different
