Q: how can i connect my phone to the tv i plug it in an its not working? i have a LG stylo 5
A: Because the LG Stylo 5 does not support DP alt-mode which is when the phone supports video/display via the USB-C port, you will not be able to obtain video/display using the JCA379. Instead, we recommend exchanging the JCA379 for the JUA165C and that will work for you. Simply download the j5create Display App onto your phone and it will work. ** Feel free to contact the j5create Technical Support team for further assistance if necessary.
