These 4 port audio visual boxes are not to be confused with online video converters. Video converter adaptors physically change the input signal for compatibility with the desired output. They are essentially a cable or small rectangular device which performs the translation process. Using these video adaptors are easy and usually require no software downloads to work. Simply plug the input end of the cable into the correct port of the host laptop and the output end in the corresponding port of the display (e.g. a projector), and the wire performs the signal translation independently.
