I was thinking of desktop, since the TV can stream video directly
by itself.

Sorry for getting a bit offtopic, my price comparison is Europe based.
4k monitors start at 330€/44万円 for a 28", for 40" one pays ~680€/92万円.
For 400€/54万円 already a 42" TV is available.

I got a Samsung UE40HU6900 for 600€.

Streaming could also mean to stay on the cable, laptop and TV have
rj45.  Indeed, h265 could not be done.  Yet, many older codecs exist.

Thanks for sharing thoughts.  
I am basically wondering if others have hit similiar issues and 
if I have overseen obvious solutions.

cheers,
