My official laptop (Dell corei3, windows 8 Pro OS) comes with an HDMI port. I use the HDMI-VGA converter when projecting using a VGA projector. It works perfectly with any kind of content and the output is excellent. The only problem I have encountered time and over again is that whenever the content to be displayed is video, it is either it refuses to display or it shows the pictures with no voice output. It give a message that implies low resolution problem. How can I best resolve this issue?
