I have a laptop with a VGA, 3.5mm audio and HDMI outputs. I use it with a pre-HDMI receiver that has 5.1 sound surround and a video projector with a composite input. Currently I use the VGA and 3.5mm audio combination. However, I am thinking it would be easier and simpler to use the HDMI output together with a HDMI-to-composite converter. Connect the audio red/white to the receiver and the video yellow to the projector. My question is whether the image and audio would be improved, degraded or unchanged. Thanks.
