Supported Hardware - Video
Display
If your device supports video out, you can use a screen on your device. (RPI3/3b/3b+ will not the OVOS GUI, ovos-shell, due to lack of processing power, but you can access a command prompt on a locally connected screen)
Touchscreens
OVOS supports touchscreen interaction, but not all are created equally. It has been noted that on some USB touchscreens, the touch matrix is not synced with the OVOS display and requires an x11 setup with a window manager to adjust the settings to work.
