I see Viewer app for iOS, but not Apple TV.
Really want to use this software again to use my new Windows gaming laptop on my Apple TV as a secondary monitor.
Hi @speedingcheetah,
spacedesk Viewer for Apple TV is not supported at the moment.
In the meantime, you can maybe try spacedesk HTML5 Viewer on your Apple TV.
Just open a web browser, then go to http://viewer.spacedesk.net/ and connect to the IP address of your primary machine.
Keep in mind that this HTML5 VIEWER is much slower than our native apps on Android/iOS/Windows.
This is due to technical limitation of HTML5/Javascript.
