Alright… so I bought a new tv from Amazon: http://www.amazon.com/gp/product/B004MME76A
Panasonic 55″ GT30 3D Plasma
I ran break-in slides for the first 100 hours (just for picture) and I finally got to actually watch the tv Saturday night. I setup the custom mode setting for the tv turning off all of the image enhancing effects that I could and the input lag for the tv + my receiver is less than 25ms!
I was actually able to measure it this time since I found a display port to hdmi connector for my laptop and followed the procedure here to test: http://www.avsforum.com/avs-vb/showthread.php?t=1166196
Game mode seems to actually produce more lag than custom. I’m thinking about connecting the PS3 directly to the tv (sans-receiver) but I really think that the receiver could be only adding on 5ms of lag at the most. Plus it would be a huge inconvenience to have to switch the input on the tv and the receiver every time I wanted to play a game. (Still might do it)
Either way.. I’m able to play videogames on a big tv now.. yay me. I’m still getting used to the size of the tv. I think that has affected my playing a decent amount too.
