Re: [tlug] using a TV as 4k display

[Dotpix <g.scarsella@example.com>]

Hello Chris,

It would help if you also explain what's the final purpose... just 
simple usage as desktop or streaming movies?
AFAIK DP 1.1a should reach 2560x1400 as resolution but of course is not 
suitable too for your needs the same.
Are you sure TVs are so much cheaper than screens? I found many 4k 
screens starting from 30000¥ with really nice colors from ASUS and DELL.
Also if you get a screen with OLED technology i doubt you can find so 
much cheaper TV having it (so consider image quality too).
If 2560x1400 is enought for you there are plenty of 20000¥ and 30000¥ 
used 30inches screen in Akihabara in good conditions and they should 
work with you laptop DP (you can try there too).
Streaming a 4k signal over a wifi sounds a bunch of data. I doubt your 
laptop wireless card can even make it (and for movies i also doubt CPU 
can make it in H265).
I'm curious ... if you want to share the info .... which model of TV did 
you buy and what price and where?

Hope some of the infos and opinions where useful to you :)
