[tlug] using a TV as 4k display

[Christian Horn <chorn@example.com>]

Hi tlug,

4k monitors are much more expensive than 4k TV, maybe because
the market is bigger.  So I got a 4k Samsung TV.

I use a thinkpad x230, it only provides displayport 1.1a,
so only 1920x1080.

Miracast is the wireless protocol to transfer HDMI over wlan,
yet on Linux it's far from usable: has only been reported to 
work on Linux on one certain wlan chip.  No activity in the 
related projects either.

The TV is able to display 4k video files offered via DLNA,
a kind of multimedia oriented file streaming protocol.

Idea: it might be possible to have Linux show a 4k screen,
encode that like a video (one of the transport stream formats,
so the displaying code does not seek to the end of the file)
and then offer this via DLNA to the TV.

Anybody directly seeing why this might be a bad idea,
or having experience with other solutions?


cheers,
Chris
