Thanks for your response. As of this point, I'm not sending the pj back either. The only times I seem to really notice the pinkish hue, is when watching a hockey game, or a movie with a snow scene. I noticed you said you are using Monoprices Redmere HDMI cables. Have you noticed any difference from that to a standard high quality HDMI cable? I have always wondered if they really work, or not. As for the IR emitters; I am using a Xantech external receiver with repeater with emitters, since all my equipment is located within a cabinet. I'm hoping that will still work when I do start to use the 3D capabilities of the 8000.I actually have almost the exact same screen setup as you which I am sure has nothing to do with the fact that I have a slight pink tint at the top right corner and lower left. Much less than 1/4 of the height and quite slight especially with my settings the way I like them. I am not thrilled over this fact but I wont send the pj back over this. As for 3D over HDMI, I see no reason to think it matters but I am using HDMI 1 on mine. I have a 30' redmere cable and I am not fully sure about it yet. It seems fine from an HTPC and from a Sony BD player (what I use for 3D) but it may or may not go black with my Kdlinks HD720 while showing a menu every once in a while. It may also be normal on the KD since I have never hooked it up anywhere else.
Sorry to not be more help.
BTW: the 3D control emitters even set at the lowest power setting almost kill the IR from my other remotes. The one for the pj and for the players and my LED lighting all need to be aimed very well to get over that blast of IR from the pj. If I was going to be serious about 3D I would use an external emitter placed in front of the viewers.
