I've had this TV for about a 1 and half years now and its been great (other than the sparkle problem-Fixed).
I recently picked up a Mac Mini and decided to use it on my TV for a media center. I have it hooked up through HDMI and it works, but my only problem is that it doesn't get full screen. I tried changing the settings on the Mini and the TV, but nothing was better than keeping the Mini at 1280x720 and the TV at 16:9.
I did some reading and I found after a firmware update, it gives the TV the capability to do 1:1 pixel mapping. It's called 'Just Scan'. I believe that would fix the issue, but I can't find the firmware update anywhere :/. I've checked Samsung's website and browsed all around the forums and I came up with nothing.
Any help would be greatly appreciated!
