I currently have a Mid-2010 iMac that I am using a Kanex XD to play my Playstation and Xbox on, and being limited to 720p is frustrating and doesn't do the display justice. In my research I found the Atlona AT-HD620 which is able to scale a 1080p image up the the iMacs 2560x1440 resolution. Not a perfect solution either but in my reading of reviews and comparisons it seems to offer better quality than the Kanex or similar. Now the only problem is it's been discontinued, and neither a call to Atlona nor checking the usual places to get one used yielded any results. I haven't been able to find any other products that will do the same thing, or a source for the AT-HD620 that still has any available. Can anyone point me in the right direction here?
