Reach maybe 20 mbit / s. Can I imagine the netflix says that 25 mbit / s are necessary, so they are on the safe side.
The question is, if you can reach this 20k. For these offers is not always groundless "up to…" before.
But you can look elsewhere (like Youtube) a few 4k videos to see if it works. Especially at different times of the day.
That's not worth it anyway, because you can't even see the difference in physical viewing distance to the screen physically through the eyes. 4K was just introduced to quickly buy new equipment, and because the high-resolution screen technology is needed for very large computer screens in front of those man then in arm's length, because no matter what you do on the computer, more desktop space is always good.
In addition, even most of what today is broadcast in HD, is usually only 720p format, or even highly interpolated from SD video.
I've read at Netflix for 4k it should be minimum 20 Mbit, as Magical Monday says but is the question of whether the 20 Mbit always arrive.
Right, I have a 49 "FHD in the bedroom, of which I'm maybe 1m away, FHD is still perfectly OK.
And 1m is actually too tight at 49 ", because you do not already have that in mind without your head moving What do you think, why in the cinema are the most expensive seats in the back?
Yes, for the distance he is quite big, but does not bother me, just to say that 4k is overrated. I still like the picture in the distance. When I play with the PS4, of course, I see pixels, but not with the television.
