The PC to TV converter I purchased from Radio Shack was a Gigaware
the Radio Shack reference number is 25-233. It was around $90.00
It connects to the PC in the monitor connection. (the laptop I needed it for did not have an S-video out I did not know it at the time I purchased it and Best Buy would not let me exchange it - needless to say that was the last laptop I will buy at Best Buy and the last laptop I buy that does not have S-video).
It also has a USB connection that gives the unit power. It has a video (RCA) output and a S-video output. I have split to as many as four TV's through the video output and it works great.
