agree on the keystone issue.... but, never could visibably distiguish any degregation in picture quality in using 1 or 2 keystone corrections... But, I mounted mine lower (albeit differently) to never have that ugly reminder that I could be getting some degregatioin from keystoning. How far back and how wide is your screen with the Z2 FP?(sorry if the dimensions were already given at beginning of post), I'm getty lazy in my old age. If I can every get my cheap digital camera working again -- I'll post how I lowered my projecter. (I also direct wired the power, so I didn't need to expose the socket and plug... was an easy step, and hid one less wire from hanging off the projector))
