A:Answer Thank you for submitting a question. The JCA379 device can be used with phones, tablets, computers if you wish. However, the JCA379 does require DP alt-mode in order to work for the HDMI which is when the phone, computers, tablet's USB-C port supports display/video via USB-C; if it does not support DP alt-mode or video/display via the USB-C port, then this device in particular will not provide you a display and therefore, we at j5create can recommend a different device in order to meet your needs.
