On the second page of this review, found at audioholics.com/reviews/projectors/viewsonic-pro8100-lcd/remote-control-menu-system
, the reviewer explains LTI and CTI are for Auto Luminance and Chroma Levels which he turned OFF. He also made a significant comment on Detail Enhancement that worked well for me:
"Under the HQV settings you have access to Detail Enhancement, Film Mode (auto is default), LTI (a luminance level "enhancer" and CTI (a chrominance level "enhancer"). I left both LTI and CTI off, nor could I seem to ever get any significant (ie perceivable) change in picture quality when using them. Regardless, anything thing that automatically adjusts color should be 'Off' in my book. Detail Enhancement is a nice feature, but the default setting of '5' is WAY too high. In fact, it introduces large amounts of noise into the picture. I'd recommend leaving this on, but set it to '2', you'll get a much nicer presentation overall and you won't miss any true detail in the process.
There is no noise reduction for HD sources on the Pro8100. This is unfortunate, however with any HD source the Noise Reduction submenu remains grayed out, eliminating both the Mosquito Noise Reduction (MNR) and the Block Artifact Removal (BAR) functions of the projector. Our suggestion would be to run anything that isn't HD as 480i to take advantage of these excellent features."
I am not seeing the problem with the iris so mine is still set at default.
Chief Mfg's Mount Finder shows they have 65 universal mounts that are compatible with the Pro8100 here:
Also the reviewer at audioholics above raves about his PRG-UNV Precision Gear mount by Peerless on the first page of his Pro8100 review.
I am a CRT guy that wanted a projector for my computer room which has space constraints and limited light control. I am enjoying the heck out of this projector and appreciate the comments on it here that enabled me to pull the trigger on buying it. I think the current pricing for the Pro8100 is an incredible value.
The negative comments on the blacks made by a number of the reviewers is not real world issue in rooms like my computer room which has off white walls and limited light control. LOL. I could read a book in here during the brighter scenes with the light reflecting off screen back onto the walls because the room is not very big.
Have FUN guys and keep asking questions because anyone who buys this as his first projector will be almost clueless in terms of knowing how the controls will effect their image without some dialog here !!!
