I love my xbox on the wall!
I now have xbox projected on the wall (no screen) and love it. It is 10' diagonal, or about 8' x 4'. It is a sharp xv-z2000 dlp and I have no rainbow effect. The only time I can see anything is when my computer is projected, when I look away quickly from the mouse. It is out of the corner of my eye. I can't imagine for the life of me people getting upset, or sick. I got motion sickness playing too long on crimson skies on my rear projection 56inch, but it is awesome now on my wall. I was going to get a screen, but now see no real reason too. When the projector is off, my living room looks normal with a simple stereo system, speakers, plants, etc...
But when I turn on the projector, I am in another world. Halo2 is good, but try playing Doom3, or Amped2. Very nice games on the wall. Doom3 scares me though, so I only playonline live with others, otherwise it's too spooky. I was worried about rainbow effects, no problem with that. I was worried about ambient light, no prob there either, and the picture isn't too big, just right. Plasma can cause burn in like crt, but not lcd or dlp. I hooked up a home theater pc to the projector for a true hd pure digital picture. WOW!
I got my projector from digitalliquidators.com for $2850, and the brand new top of the line pc 3ghz 200gbt hd, digital optical output etc... from ebay for $685. My reciever is Kenwood from ecost.com. The rest of my stuff I have pieced over the years. All I can say is that no one leaves my house without re-thinking their idea of home theater and home entertainment. This forum helped me greatly as I spent hours a day for months racking my brain on the many decisions to be made when buying a Hidef tv or projector. So thanks to all of you, I am one happy man.
My xbox name is "islandberserker", so if you see me there, I am a fun player.
later,
