HD, portable and practical
The ViewSonic M1 Pro projector is a practical little gem with its built-in battery. It was incredibly quick to set up when first used. As a second screen, wireless connectivity was instantaneous as soon as the projector was connected to the WiFi network (macbook pro m1). Quite a quiet fan, and I'm very pleased with the image quality, colours, brightness and the small carry bag provided.
I just thought it was a remote control problem because the batteries supplied by ViewSonic in the box, even though they were in a blister pack, were empty or faulty. In the end, when I replaced them, the remote worked straight away.
