Internet Speed for 4K Streaming
How much speed you need for 4K video.
4K streaming needs more bandwidth than HD and also benefits from a stable connection. The required speed depends on the service and compression quality.
A single 4K stream may work on moderate speeds, but multiple devices need more capacity.
If 4K video buffers, test near the router and check whether other devices are downloading or streaming at the same time.
Quick checklist
- Run a fresh test after changing one setting.
- Compare Wi-Fi and Ethernet when possible.
- Check download, upload, ping and jitter together.
