How do I use Speedtest on Apple TV?
To use a Speedtest on Apple TV, you must first download the dedicated Speedtest by Ookla app from the tvOS App Store .
Once installed, launch the app using your Siri Remote; the interface is simple and built for the big screen, often displaying a large speedometer-style graphic.
Simply navigate to and select the prominent “GO” button using the Siri Remote’s touch surface or clickpad to initiate the test, and the app will measure your Apple TV’s network performance, providing the ping, download speed, and upload speed directly on your TV screen.
