HDMI or what we called high definition multimedia interface is a computer port that communicates audio on and video without the requirement for compression from a HDMI amenable source video such as compatible computer monitor, display controller, digital television or digital audio device and video projector.
The universal and ever-handy port is featured on a surprising number of HDTVs, and if you have it you can connect VGA-to-VGA with the appropriate cable. VGA only carries the video signal, however: for audio you'll need to go through the laptop's audio-out jack, which in some cases doubles as an optical audio-out port. You can buy a cable splitting off to RCA outputs, or plug an audio cable into an external speaker bar.
