UST Optima and LG et al CIH with projector movement

What are the chances that the new UST projectors can be slid out easily and up or down to zoom the 2.35 image to full screen when watching on a scope screen and switching from 16x9 material.

HTPC. Onkyo 636, Polk audio speakers and Klipsch sub. KHO-7 Outdoor speakers. Homeseer homecontrol over Z-wave.

I use this method with a conventional throw projector that is considered a shorter than average throw projector with great success. The projector I use like the USTs doesn’t have enough zoom, shift and lacks presets to do CIH. I mounted mine inverted on an inclined rail DIY mount that allows the projector to move and shift at the same time. The projector I selected has enough DOF depth of field to maintain sharp focus over the range needed for CIH plus some.

To do this with a UST the movement would be much shorter and the ramp angle much steeper and my guess is with each adjustment some focus would be needed. I’m not very up on UST projectors and their setups but I’m guessing the movement mechanics would need to be very precise.

Maybe some of the people with them will chime in and tell us what would be needed. Or maybe even try it for us.

I would think USTs would be too sensitive to position variance to work this way without a lot of overscan. Everything would have top be bolted down and very precise. Drawer slides might help.

Agreed with ScottAvery. I have the HU85LA and tweaking its position on my TV stand by even a little wreaks havoc on how square the picture is. You would need a very precise set up for what you are proposing. Good luck!
