Hi Lylell, Your LG Studioworks 221U Monitor's input uses either a D-Sub which is a standard 15 pin vga cable or a 13W3C cable which is for cad workstations. On the other hand the output of your Dish Network receiver is either RCA-type audio/video or an S-video output. Since all are not directly compatible you would need something in between and not just cables. Technically what you need is to convert composite video output to d-sub 15 pin video input. A fine example is COMP2VGA by www.startech.com originally designed for gamers. There are some in the market that are simple connector to connector such as in http://www.trianglecables.com/1footvgadbma.html, please don't bother since it has been known not to work. To complete the setup, you would need a stereo amp/speaker pair for the audio out of your receiver. Hope this be of some help/idea. Post back how things are or should you need further information. good luck and kind regards.
