So I bought a Mini DisplayPort to HDMI adapter online, however had no luck getting it working properly. The picture will appear on the TV for a split second before going blank, and I can hear audio crackling too. When the picture does appear, everything looks fine. HDMI cable is working fine with other equipment. I've read about problems with mDP to HDMI, but most were from 2009, and I was hoping that everything would work now. The adapter I got from Amazon - it isn't the most expensive one out there (Akord). Who has this working, how did they get it working, and what is their setup/adapter?
