I am trying to connect an HDMI cable using a mini display port adapter (supporting audio) to my LCD monitor. All I get is the desktop pattern but nothing that's on the browser or folders on the desktop, nor do I get any sound. I tried selecting "PC" as well as "HDMI/DVI" on the monitor's source menu with no success. Formerly I was using a mini port adapter to DVI cable which worked fine though no audio. I'm not sure if this is the proper forum to be asking for help on this but I would appreciate any help I can get.
