vCastSender, the official Viewsonic app also allows you to use your smartphones display as a touchpad to navigate through the OS. It can come in handy if you happen to misplace the remote controller in the dark crevices of your backpack or couch, but otherwise the standard issue remote control works a lot better.
One of the most common foibles of portable projectors is the app store that’s included as part of the OS and unless it’s a Google TV or Android TV OS, the experience is typically lacklustre. The M1 Pro has a rudimentary app store with Netflix, MX Player, Spotify, Twitch amongst the known apps and a lot of obscure ones, but none of which provide the same level of refinement or speed as a Fire TV stick or USB-C connected smart device.
Capable of being used as a stand-alone Bluetooth speaker, only for audio, the M1 Pro does a good job at maintaining dialogue intelligibility, playing loud without distortion and even being a music speaker for background listening. You actually could watch a full-length movie through this projector without having to turn on the subtitles and that’s commendable.
