· 3 pulledIf you've ever experienced poorer picture quality than expected while streaming Netflix shows or movies, you might be wondering if you're actually getting the 4K resolution you're paying for.

The easiest way to check your current stream quality is by using Netflix's built-in diagnostic tool, which displays real-time information about your video stream.
