1> The Atlona HD620 will pass audio from the HDMI to iMac 27" or 27" LED display via Mini DisplayPort Connection; however Apple 24" LED can't take audio from Mini DisplayPort (only through USB), therefore user would have to either use a separate audio output from the HDMI device to connect to AV Receiver or can also use an analog stereo output from HD620 to connect to a set of powered speakers.
2> AT-HD620 doesn't support 2011 iMac 27-inch as it is based on Thunderbolt
The Atlona HDMI / Mini DisplayPort to Mini DisplayPort Scaler and Switcher is a dual input scaler, which scales HDMI input with stereo audio for display on a monitor with a Mini DisplayPort connector. With the ability to scale HDMI signals up to 2560 x 1440, the scaler supports native resolution of an Apple iMac 27” and Apple 24”. Featuring HDMI and a mini display port input, the scaler also doubles as a switch, allowing 2 sources to be connected simultaneously with a single display. It also converts 50 Hz signals to 60 Hz signals.
Supporting 3-D motion video adaptive, 3-D de-interlacing, hue, saturation, sharpness, RGB (color tone) level, and aspect ratio size, the HDMI / Mini DisplayPort to Mini DisplayPort Scaler and Switcher allows you to adjust the picture quality for crystal clear display via manual buttons or an IR remote.
