Greetings,
My monster CRT Sony 1252 has just gotten too big for my small HT room. HT hobby is quickly taking a backseat to other hobbies anyway- so I thought I'd downgrade to the LT150 projector- it's small and I can ceiling mount- allowing a few extra seats for guests!
I already have a 16x9 screen installed that is 64 x 36. Checking the throw chart for the LT150 puts me about 103 inches away from the screen, no problems there.
The problem is the position above the screen. I'd really love to celing mount, but I have low celings. The current screen mount location gives only 6 inches above the screen before the ceiling.
For a 4:3 configuration, the distances given would be impossible for me- however I was wondering if anyone knew if I could make it work for 16x9. I'm not sure how well the LT150 lets you shift the image up/down on the projection face.
According to the chart the projector lens center would need to be:
32 inches from the screen center, 8 inches from the top of the screen...
but this is impossible with my setup as the furthest away from the center it can be is:
22.5 inches (4.5 from the top), even if it is mounted flush to the ceiling.
This would normally disqualify my thinking about ceiling mounting- but I thought since I was planning to use 16x9 image exclusively "cinema mode"- the top and the bottom of the 4:3 screen area would not be used anyway (12 inches of screen space gained total). So depending on the projector's controls for position, I might be able to still celing mount and just move the image down some to overcome for my lack of headroom.
Is this possible? I have a CRT now and it's controls are really great in this regard- you can move the image any possible way. Does the LT150 offer similar picture controls for moving 16x9 around vertically within its 4x3 area? I see vert and horiz adjust on page 38 of the PDF manual- but there is little info and doesn't really say how FAR you can adjust.
I would move the screen down, but I have an in-wall cabinet and need to maintain room for the center channel speaker below the screen (unless someone wants to buy me an acoustically transparent screen). So basically the screen can't move down any further without major construction issues.
If the LT150 is not adjustable for image location, does anyone think I could angle the projector up slightly and keystone around being this far too low? Are there any issues with mounting the projector flush to the ceiling (light reflected on ceiling? heat?)
Any help you guys who have actually handeled the unit can provide would be much appreciated!

PS: This unit is DLP- so if I do use it as 16x9 mode exclusively, do I have to worry about tube burn issues?
