Our glasses are supposed to be used with the devices, which support USB Type-C with Display Port (DP) output.If DP output is not supported, then an extra adapter will be needed because of the unique transport protocols and constraints.

It is recommended that you purchase the converter in the link below and then connect an external 5V power supply and then you will be able to use the glasses.
