Projectorsno source found. VGA to HDMI

Hi Lynn, if your Projector does not have an HDMI input port and your laptop does not have a VGA output, then you will need an adaptor to transform the signal from one type of output to the other. 
USB carries only data and cannot transmit the video signal to the picture from your computer to display on the board. 
Would you be able to use a different machine that does have a VGA output?
