On the internet you need at least 25mbit / s to be able to stream 4k on Netflix? I did speed test and it said:
Download speed: 38mbit / s
Upload speed: 35mbit / s
Latency: 6ms
Is that enough for 4k streaming?
Just try it out.
20-25 Mbit / s should be enough for 4k lol
Try before studying!
But that's actually enough.
38 given, 25 needed.
If the line remains stable and there are no major fluctuations, should the answer be clear?
You answered the question yourself? You need 25Mbit / s and you have 38Mbit / s. 38 are more than 25. Ergo it works, provided the 38Mbit / s are stable.
