I have a client using a Vostro 2510 laptop who wanted to display the contents of demonstration from the computer onto a HD TV via HDMI. Unfortunately, the Vostro 2510 only has a VGA output, which is analog, and HDMI is digital, so we needed to get a VGA to HDMI converter box. I normally recommend buying through Amazon.com, but due to time constraints, they needed to get it somewhere local like Best Buy or Fry’s Electronics.
If you get a converter box, make sure you get an HDMI cable long enough too. They come in 6 to 50 ft cables. The converter boxes are easy to use, plug-and-play devices, but make sure it comes with a VGA cable and audio cable, too. Once you have it, it’s a matter of connecting the VGA cable and audio from your computer to the box, plugging in the converter box to a power outlet, and then run the HDMI cable from the converter box to the TV. Change the input on the tv to HDMI and you’re all set to go. Here is a video on Youtube about how to use the device I’ve linked to above.
