Is 11' distance from projector screen too close?

I agree the Runco gear is expensive and definitely above my budget.But I also won't pretend that it isn't superior either.The Runco Q750i LED Projector I viewed last weekend is well above the classes of the units you mention in price and picture quality. No videophile would place them even close either.The depth and black levels of the image is intense on one of these.Plus no bulbs to change.

Right now the JVCs and the Sony HW20 or VWPro1 are the best under $3000 new period! For just a hair over $3000 you can pick up a JVC RS40 3D new in the box. The poor little Panasonic has a on and off contrast well below that of the Sony or JVC and less than half the brightness at D65 calibrated. Again if you think any of the other units will compare..you're fooling yourself.

The Panasonic was considered the best under $2000. After the release of the Epson 8700 that no longer holds true. The Epson 8700 can be had for under 2 grand these days because JVC has pushed them out of the $2000 to $3000 range. It is the black level champion in this price range now.

It will fit, at very least, with any LCD projector with 2.1:1 throw ratio.
I had an old Optoma HD65, and that throw ratio fit in a room that was 12.5" deep, at the back wall, and fit on a 100" screen. You should be ok on 90" with most projector options, I presume.
If in doubt, simply go to www.projectorcentral.com, and go to the projection calculator for a given model (blue click on on left side of page).

Don't get an LG. Pretty bad all around.
