OK Listen here peeps....
I own a Belkin AV360....
I use it to marry my ps3 with my iMac 27inch
The iMac only supports 720P even though the device allows 1080P...
I sit pretty much the same distance as I do when I am surfing the web and the picture looks very very very good...
A lot go games run on 720P anyways so its all good and since your playing on a 27inch screen with more pixels and less space, the picture naturally is great...
The sound will naturally come from the hdmi source into the iMac ( ps3 to iMac )------ although on you device, ps3, xbox, blu ray etc you can have plugged in what ever audio source you desire like gaming headsets, surround sound system or whatever and just select on ur device that u want ur audio to come from the desired device an BAM... done
Generally if your iMac is switched on, and all your connections are plugged in, one you turn on the device attached to the av360, the mac will switch straight to the picture. Once you switch off your device then the mac swill switch back to your osx. ALTHOUGH... if it doesn't do this automatically or you want to switch screens without turning off your devices such as pausing your game, going on ur osx then back to your game... simply hold the command key and press F2. This will allow you to switch between both screens.
Even though the av360 automatically converts the res to 720P, meaning you can leave your device (ps3 etc) on 1080P, I would recommend changing your device to 720P. This will give you a more crisp 720P picture as the av360 doesn't have to work as hard to downscale your picture and lets it use all its powers to give you a smooth connection between devices.
In a nutshell, picture is awesome, sound is awesome.... Belkin a v360 = Awsome...
Please look me up on youtube under anfrice or reply to this blog if you want me to post youtube videos of my set up.
peace out
