I ordered this kit after much investigation for a wireless method to link my Dell desktop PC to my Vizio 37" HDTV. I had thoroughly reviewed the specs at the IO Gear website and read many reviews from other suppliers. Upon receiving the unit, I was immediately concerned since the specs on the box state that the 30' wireless range is for a "line of sight" installation and that the range is limited to 15' for High Definition video. My PC is located on the second floor of our home and the TV is on the first floor physically about 25' apart. I should say that the unit was a breeze to hook up, load the software and set up the PC. It worked like a charm for viewing spreadsheets, word documents, surfing the web, etc. just as connected. However, for watching videos, I had to run the USB cable (comes with the kit) through the second floor and connect the small Wireless USB Adapter receiver unit so that is was in the same room as the TV and Wireless VGA Adapter. With this set up it worked just fine for streaming Netflix "Watch Instantly" movies. However, I also wanted to be able to watch network episodes from ABC, NBC, CBS, etc but it failed miserably!! While streaming these shows the sound and video would break up and pause on the PC and no video would be displayed on the HDTV...just a blank screen. I moved the VGA Adapter (and TV) to within 12' of the receiver and still the same result The online help from IO Gear was totally lacking and I sent the unit back.
As others have mentioned, the kit transmits only the video, not the audio from the PC. An audio cable has to be run from PC to TV but I knew that up front.
I have since order a 50' VGA cable with 3.5mm audio from Amazon part numberRiteAV - SVGA Monitor Cable with 3.5mm Audio - 50 ft. and this set up works great!!
