Try your picture and sound
A quick check that this browser can play a short football-coloured test clip. It takes a few seconds.
Your local test
Press Play to start. Your browser may ask you to allow sound.
The sound check depends on you listening and tapping “I heard the sound”. This page cannot tell whether your speakers are audible.
Browser basics
What happens next?
This checks local video playback and a few browser features. It does not test a private room, another person, your connection to a friend, or match streaming.
When these checks look ready, open the private Same End invitation in Safari, Chrome or Edge, keep that page open, and try the room with a friend. If an invitation opens inside another app and has trouble, choose Open in Safari or your usual browser.
Keep your screen awake while watching. Phone screen capture and the desktop sharing extension are not checked here. Intended paths include iOS/iPadOS 14.5+ with Safari 14.1+; other devices can differ. Some specific older device and OS combinations still need owner testing.
Save or share this check

All checks run on this device. No network, IP address, invitation, or upload is used by this page.
