4K streaming looks blurry. Not actually playing in 4K
Your internet is probably fast enough to start 4K playback, but not fast enough to keep it going smoothly. 4K streaming needs 15-25 Mbps based on the app and quality level. Go to speedtest.net right now and check your speed.
4K video has four times as many pixels as regular HD, so it needs much more data traveling to your TV every second. If your internet speed isn't fast enough, the streaming app has to reduce the quality to keep up. This is called bitrate limiting. The app shows you the right resolution button, but the actual picture quality drops to compensate. Check your speed and what else is using your internet.

Skip — I just want a technicianCommon mistakes to avoid
- Checking speed on a device that's close to the router and getting a higher number than the TV actually gets. Test speed on a different device or at the TV's location
- Thinking the streaming app's quality setting means the actual resolution being sent. It can say 4K but the picture quality can still be reduced by low bandwidth
- Leaving cloud backups running silently while trying to stream 4K. Backups use huge amounts of upload speed and will choke your download
Signs you need professional help
- Your speed test shows 25 Mbps or higher, no one else is using the internet, but 4K still looks blurry You've switched to a cable connection and moved everything around but the picture quality hasn't improved You want to know whether upgrading your internet plan will actually help your specific setup
