Optoma projectors get another smart assistant option-- as well as Amazon Alexa, the UHL55, UHD51A and UHD51ALVe 4K UHD home projectors are compatible with Google Assistant.
Also getting such capability is the upcoming UHZ65UST ultra short throw laser 4K UHD projector.
Voice controls enabled by the assistant include power, source selection, sound output adjustment and inbuilt media player control. Google Assistant can also select various display modes and HDR picture modes, as well as PureMotion options. Enabling Google Assistant requires connecting the projector to a wifi network and registering it with an Optoma MyDevices Account.
