|
|
Hello,
New here and don't have a lot of experience with CRT projectors.
I recently inherited a Runco DTV-852 and want to do a ceiling installation. The problem is that the ceilings are high at about 12 feet. I would rather have the projector flush with the ceiling then install an extension bar to the unit. I plan on having it setup for a 10' screen width, which I believe puts it at about 12 feet from the wall. In the flush mount scenario, will there be any way to compensate for projecting the image at an angle?
Thanks for any guidance in this,
Stefan

Yes, lots of keystone adjustment in the set, but you most likely will need to drop the set down via an extension pipe. Only the super high end projectors have more keystone adjustment, and even then you're limited.

The keystone setting if I read your post correctly.

I see. So maybe dropping it down to 10 feet with a pipe and adjusting the rest through the keystone settings?
Thanks for the quick reply!

I'd much rather be in your shoes than have my current low ceiling.

isn't anyone going to mention that 10' is way too big for this projector or any CRT projector for that matter even with a high gain screen?
There are a lot of negative reasons to use as little keystone as possible BTW.

You could always adjust the screen to compensate for the keystone. Also stick with a smaller screen, say 7 - 8 feet wide. Your picture will be much brighter and have more punch.
Keep in mind the projector generally needs to be even with the top of the screen.

Like what? That should say there is lots of GOOD reasons to use as little keystone as possible.
Id be dropping it alot lower than 10 feet from the floor...

Yeah I messed the wording up.
I meant to say you should use as little keystone as possible. Using keystone has compromises

The only real compromise with keystone use on a CRT is less phosphor usage and uneven tube wear, its not like a digital where you lose resolution. But still, the more tube face you can use the better.
