Raspberry Pi on LKG 15.6"

Hello,
I didn’t order a LKG Portrait because I already have a 15.6". But I wondering how can I use a Raspberry Pi with the 15.6" like it is state with the portrait ?

It’s very annoying to use a laptop aside the LKG. So I’m looking for a real workaround. I so on the forum only experiments :frowning:
