My laptop has a VGA device on the back.

Eagerly I went to Gamestop, and purchased the $40 cable.

I came home, and plugged it in, only to my utter dismay that it would not work!

I called up my laptop company (Acer) and they told me my VGA device only works for output, not input!

Disappointed, I returned the cable and got my money back.

Consumers, make sure your VGA device is input and output!!
