This cable is to connect a PC to the Philips PPX2450 or PPX2480 pocket projectors.
The cable is 1 metre long with a mini-HDMI connector on one end for the projector and a VGA connector and stereo jack plug on approx. 1 metre of audio cable on the other to connect to the PC. The VGA output from a PC does not have audio so it is necessary to plug the jack plug into the headphone socket; the 1 metre of audio cable allows for these to be separate connections.
The cable is well made, reasonably flexible, and works well.
