best screen for 4805

[Taz1]

What would be the best screen for the 4805. I was looking at HCCV. From the review at PJC., Carada seems to have lots of light spill.

Any suggestions will be greatly appreciated.

Thanks

Taz

bump.. I would like an answer too!

I was thinking HCCV with ND2 filter would be a practical alternative to the gray Carada. (Carada was favored at a recent shootout..) About the same gain, and you can take off the filter when the bulb fizzles after a year or so...

The sparklies I saw on my HCCV sample has me a bit worried. Anyone with "real-world" experience with HCCV care to comment on this possible problem?

I'm very curious also...

I have a 4805 on order and am researching screens right now... I need a pulldown screen for WAF. So I am looking at comparable pulldowns to the Carada grey that everyone at the shootout seemed to rave about...

I was thinking HCCV, but now that I'm looking at dalites site, I am not even sure that this fabric is available in a pulldown. Does anyone know if it is? How about any alternatives that I can use instead?

Thanks,

I was thinking cinemavision with 1.3 gain because I will be going with 106" diag. If you want one let me know maybe I can get us a discount on the screens. I can give you their 1800# and they have the best prices I have ever seen on da-lite screens.

Da-lite's pulldown "equivalent" to HCCV is HCMW (High Contrast Matte White). It's not really white. In fact it's darker than HCCV, if I recall... HCCV is a PVC-based screen, and cannot be used in a pulldown... HCMW is cloth-based...

Judging by the early reviews coming in from the projector forum, the 4805 is to bright for a white screen (without filtering). Most everyone who has reported in on their new PJ's are saying they are going to a gray screen.

Thanks Frank,
that helps out a lot... I was looking at the HCMW trying to figure out what the difference was between it and the HCCV... and now I know. Do you guys think that this would probably be my best bet for a screen in the 80" or 92" width range.

Thanks again,

I heard the HCMW screens were better at keeping 'wavies' to a minimum.. the horizontal ripples that are common with pulldown screens. True?

I've heard that for sure about the High Power... but I'm not sure about the HCMW. I'm curious too, because it is now one of my front runners for my theater.

I have the HCMW and there are waves at either side running vertically. I also have the tension bar which keeps the screen taut vertically in the center area but doesn't work for the complete screen surface. It is a beautiful screen which deepens PERCEIVED blacks and contrast ratio. It helps with ambient light as well by rejecting reflections. I also have a high power which I just received this week. Different animal entirely. No waves and very punchy picture but the blacks and contrast suffer when compared to the HCMW. You can have lights on though while using it and the image doesn't suffer much which is kind of nice.
I would definitely recommend the HCMW. I will be using it as well as the high power as the occasion arises.

You may want to see if someone in your area has a HCCV and wouldn't mind if you take your projector over there for a trial run. I have let a couple people come over and try their's out on mine.

Potus - Since you are in the Chicago area, you are welcome to try it out on mine if you don't mind coming up to the North Suburbs. If interested, send me a PM.

I am looking for an answer to this question as well.

I plan on having a 92-106" diagonal screen with controlled lighting, but some light on behind the pj.

Is a gray the best way to go or another type w/ ND filter? Thoughts and opinions appreciated. Thanks.

[Taz1]

I was told HCCV for a larger screen such as 106-110" with ND filter.

Did you consider comparing the HCMW with the HCCV. I understand that they are very similar in the results you get from them. I'd be curious to know if the HCMW has the same sparkles you see on the HCCV...

Kyle - Unfortunately DaLite messed up when they sent me my screen sample pack and sent me 2 matte whites instead of a matte white and a HCMW. I haven't seen this material. The HCMW is only available on pulldown screens, so I didn't even consider it to tell you the truth. DIY would be tough as well, since the material has no elasticity to allow it to be stretched over a frame.

[Tom_Bombadil]

I haven't seen a 4805 yet, but must admit that I find these suggestions puzzling.

Isn't the 4805 rated at only 750 lumens?

I don't understand why someone would want to employ a .8 gain screen (HCCV) with a ND2 filter on a 100+ inch screen with a 750 lumen projector. The combo of the HCCV with ND2 would cut the brightness by roughly 50%. That seems drastic for a relatively low output projector.

[JeffKB]

Tom - actually HCCV is 1.1 gain, not .8 (HCDM is .8 gain). Also, keep in mind the lumen spec for this PJ is "video optimized" lumens, as opposed to max lumens, which many projectors often cite. With other PJs with a spec of 750, you would actually wind up with around 450 lumens after calibration. Not so with the 4805, you should get a full 750 (high lamp mode) or 600 (low lamp mode).

Having said that, I do agree with you that the filter idea may be a bit unnecessary. I own a 4805, and although it is bright, it is not unbearingly so. I'm projecting to 92" diagonal, and I don't feel I need one. If I were to go with a 100"+ grey screen, like you mention, I wouldn't even consider using one. Of course, that's just my personal preference. Those who are trying to achieve ultimate black levels may have a different take.

IMO, a filter would work best if you had a smallish white screen and you wanted to tame the brightness to improve blacks.

[Tom_Bombadil]

Okay, I had my Da-Lite screens mixed up. Thanks for the correction.

My projector produces 1200 lumens at low power and I don't find it overly bright at all when used on a 100" screen.

As I've mentioned in other threads, if one does get a ND filter, make sure you get one with anti-reflective coatings. Many do not have these and without them the increased internal reflections will decrease contrast.

You mentioned using raw material from Stewart... Has anyone else tried this? Does it come with binding on the material ( I hope) ? WTB?

Many thanks for the screen review.

Thanks!

[JeffKB]

Cary - I know raw material is available from Stewart, but I don't know what the edging options are. AVS sells it - contact Jason. I'm sure he'll know. :)

Many thanks! I contacted Jason and got details and pricing. I will probably go this route.

I use the (popular here) 92" Optoma Graywolf. I like it when I'm sitting DIRECTLY in front of it, the contrast of bright and dark is amazing. XBOX and HDTV look amazing. I like how it's a little dark when sitting, standing the picture is super bright. When I'm outside the cone the picture gets darker, but if I sit for about a minute my eyes would adjust then everything will be fine. Since I hardly host parties, I'm the only one really using 4805/screen (wife prefers living WEGA TV), I recommend the Graywolf. BTW, I sit 12' back, light adjustable canned lights, 4805 about 7' off the floor.

looks like you've already answered the lighting question, but do you have a dedicated room for the projector? a 'dark room'?

I live in an apartment, and am using a crappy BOC atm. looking to get the graywolf, the projector is table mounted. I have gray carpeting, and white/beige walls/ceiling. I might try to wall-mount the projector about 7ft up as well, not sure.
