Ready to pull the trigger on CIH with my Pearl- should I in my situation?

post #1 of 16
Thread Starter 
Hi,

I purchased a Sony Pearl a couple of weeks ago to use with my existing 45x80 screen. The Pearl is ceiling mounted as far back from the screen in my small room as possible. The exact lens to screen distance is only 11'2". I plan on purchasing a Panamorf UH380 lens, Lumagen HDq scaler and a 45x106 screen. Viewing distance is about 10'4". I know a minimum lens to screen distance of 12' is recommended. Do you think that my 11'2" lens to screen distance will degrade 2.35 picture quality? Will I be able to use a screen 45x106 inches? Just the lens and scaler alone will cost me over $3,200 so before ordering I want to make sure this setup will work well for me. Please share your opinions with me if you wouldn't mind. I am dying to order this stuff from Jason as soon as possible.

Thanks!
Tom

Can you try it out just using zoom and lens/picture shift? That should give you a close approximation of what it would look like. A lens would improve brightness and perhaps resolution (dependent on source).

Tom - the Lumagen is supposed to work wonders with the Pearl. To cut costs a bit and still have top performance, you could go with an HDP (the price recently dropped) instead of the HDQ (generally same processing and essential vertical stretch for CIH).

You could also get a U85 for cheaper than the UH380 if you don't mind going VC.

It will work just fine the 380 will HE the picture you are throwing now to 106" wide with the same throw distance.

johnovox- He can not use the U85 as it will just squeeze his current picture too short he does not have the room to move the projector back any to get the throw needed for the width.

Good point Nate. I didn't focus on his room dimensions.

My projector doesn't have the zoom range to get my wanted 106" width desired. I zoomed out to about 98" wide and wasn't impressed with the picture quality using the zooming out method. I did refocus by the way. I hope the pq with UH380 lens and scaler look better than this.

I was not aware that the Lumagen HDP would work for me. It could be a great cost cutter. Does the HDP have a 1080p input and output? Also, does it have 1080i component input and output?

Is it very likely that pq will be significantly superior using lens and scaler compared to pq using the zoom out method? The answer to this question is the ONLY thing that could keep me from buying the lens, scaler etc.. I only use the projector to watch High Def movies on HD-DVD, Blu-Ray, D-Theater tape, and hd movies recorded on DVHS from cable HD premium movie channels.

Thanks,
Tom

My contacts must have been dirty the day I zoomed out and checked pq. Tonight I zoomed out as far as possible 96" wide. The pq was absolutely outstanding! I think if my projector had a bigger zoom range I would just use the zoom method at least for now. Gotta love these 1080p projectors.

Was it the same source? I have a lowly HS10, 1368x768. Zoom works great for HD sources, DVDs upscaled through my HTPC are OK as long as they are a good transfer, poor ones are unwatchable.

I plan on getting the RS-1 and using the zoom method until I can afford the lens-scaler combo. Glad to hear that you were impressed with your zoomed quality after a second look. I've ordered the parts to build a new 2.35 screen so hopefully I'll have it built and ready to go by the time I get the RS-1.

I'm considering a Pearl for my CIH setup as well...how do you find the remote zoom and focus? I would ideally like to program a macro that could move the zoom/focus for 16x9 and 2.35:1 viewing but I am skeptical that this would work in practice. Anyone have any success with this?

In general do you find it easier to zoom/focus using a remote for a CIH or would it just be faster to do manually?

I'm doing 2.35 with my Pearl, and it takes about 15-20 seconds to zoom & shift with the remote. Not a big deal at all.

I do it with my HS10, it happens that the zoom ranges work perfectly, min zoom for 16:9, max for 2.35:1. I have a macro to do this, but it wouldn't be bad manually either. If you had to use less than max, programming it might be hard since you probably cannot save zoom settings.

I don't find it necessary to refocus, which helps.

I put a call into Jason Turk yesterday to place my lens, scaler and 2.35 screen order but haven't heard back yet. I am DYING to get this stuff and anxious to view 2.35 films the way they were meant to be viewed!

I only watch HD movies on my projector. Using the zoom method, I could get a max 2.35 screen width of 94" with viewing distance slightly over 10'. If you guys had to choose, would you do 45x106 using fairly expensive lens/scaler or 40x94? My current screen is 45x80.

Thanks,
Tom
