Hi everyone, I've had an iPhone for a few years now, but have always been a PC guy. For xmas, my fiancé bought me a new Macbook - 15 inch screen, 2.4ghz, 750gb HD, intel core 7, etc. Nice little machine that I am just learning how to use haha...much different from what I'm used to! Anyways, I'm wondering about the lack of HDMI ports. I ordered a 3rd party mini display port to HDMI converter, but realize now that it's now the Griffin model that Apple recommends...it's an aftermarket brand? So, two questions: 1. Is there any audio/video quality loss when going mini-display to HDMI as opposed to straight up HDMI? 2. Is there something wrong with purchasing an aftermarket brand? I read somewhere that there might be audio issues? Thanks!
