HDMI to VGA adapter

Hope I'm not desecrating my favorite site with a Windows inquiry. We just purchased a Acer PC laptop for multimedia and found that it came without a VGA port. Now we need an HDMI to VGA converter in order to hook up to our projector. From what I understand, we need more than an adapter in order to convert digital to analog. I'm including a link of an HDMI to VGA adapter. Could someone tell me if this would be sufficient? From the description, this would be all we need. But others are telling us we need a converter box (USB to VGA).





So, what exactly should we be looking for?
