I'm having a bit of an annoying problem on my PN50C7000 (and I assume it's the same for all current Samsung models). I have a receiver (Denon AVR-1911) with a PS3, Wii, and a Dish box connected to it. The input lag on the TV is pretty bad, so Game Mode is a requirement for the Wii and PS3. However, I don't want it enabled on the Dish. The problem I'm having is that since I'm using a receiver to handle everything, the receiver just has one HDMI-out cable going to HDMI1 on the TV, so it basically thinks HDMI1 is one single source. Is there a way to get the TV to detect which input the receiver switches to? If not, is there a quick button to push to switch it back and forth so I don't have to go deep in the menu to switch it each time? I'm sure other people have had this problem, especially on this TV with its terrible input lag... please help! Thank you!
