The more I know, the more I don't know. I borrowed an X1 from the school I work at and it easily convinced my wife that FP is the way to go even after checking out my cousins new Samsung 60" or whatever it was. School starts soon, so I need to take it back. I will mostly watch movies with it. HDTV, gaming and regular TV are at this point very unlikely. Light control is not an issue. 4:3 works for me. When I do watch a 16:9 I adjust the zoom and roll up the screen and it looks just fine. I'm not sure I have seen rainbows, but Marlin, in Finding Nemo has an orange "halo" around him on my borrowed X1. What is that? I like the price at buy.com for the 6100 but the others are also at a good price also. I will run it with a Denon 900 DVD player. Does any one set-up a outdoor theatre? My family and neighbors are ready to bring out their lawn chairs. Any help or suggestions are always welcome for this newbie, Thanks!
