Your 100" 16:9 screen would be equivalent to a 96" 2.35:1 screen (same width), with the same screen material, for the same brightness. If you want to go larger (and keep the same brightness), you need to look at screen materials with a higher gain.

I haven't set up the 3D PJ yet. I still have to finish my HTPC build, and other tasks have a higher priority, right now.

A 96" 2.35 screen would be too small, as I now project the 2.35 image in my 100" 16:9 screen and it's small.....for my taste

Optimun size would be the 120 on, 2.35 screen. I am thinking of probably building a 120 DIY from blackout cloth (BOC)to test how it looks before committing to buy the Carada....

Let see if I manage myselft to do it....

Is there any thread on a BOC DIY you may refer me to?

thks...

Does the 4:3 aspect setting only work for non-hdmi video input? I have only hdmi running to my hc6800 and I only get three aspect choices. 16:9, anamorphic and anamorphic 2. I have it set to 16:9, but when I change the cable channel from hd to a non-hd channel the picture is small.

Placed an order for one. I am used too, (or spoiled I guess), to the powered focus/lenses shift. I bought the Epson 8350 and hated the manual shift/focus. They felt very cheesey and sloppy. I also developed a problem at appx 100hrs. When I hang a PJ I only want it to come down because its my choice, not to send in for repairs/exchanges etc.
Reliability is key and a sharp picture is a must.

I have had a few Mitsubishi products and it is good to hear the reliability reports.

The CIH is a special treat, I am currently using a 100" 16:9 electric screen.

Okay, here is my question, has anyone had any experience with the 3D- Theater and this projector?

Thanks!!

One problem I noticed while testing the 6800 CIH function is with my masking. I am planning to use dark navy blue curtains to mask the 16:9 vertical bars.. However, I was a bit disappointed that I was able to see w/o much trouble the reflection of the gray bars on the curtains...which I wasn't expecting to see that obviously....

They are very dark blue, although not black, but I thought they should do the trick. Does my problem has to do with them not being black or is it normal that I saw the light reflections (gray bars portion of the image) on the masking curtains?

Anyone with a similar set up with the 6800?

Guys, please help. A local installer recommended the HC6800 for my dedicated media room (light controlled, no windows, dark carpet/walls, etc) and the Vutec Silverstar screen (110in).

What do you guys think? Will this screen work well with this projector? The main purpose of the room is to watch movies (in total darkness) and HD sports (with ambient lighting on).

Please help...

Did your Local Guy tell you that this Model is about to be replaced in 3 months with a unit that has 2x-3x the contrast.

Are you talking about a 7800 model that someone mentioned.....
post #968 of 1120
I got mine in the other day and for 300.00 more than the Epson 8350 it looks and feels like thousands more. I am very happy!!

I wish I would not have waisted my time with the 8350, not that the 8350 is that bad, its just that the HC6800 is in a different league in my opinion.

The official Model number has not been annouced yet but yes there is a replacement set to release for Fall.
It will fill the Hole between the 4000hc..- 9000hc...
The 6800 is a great unit it is just ready for a replacement. should have had one last fall.

The 6800 did not start shipping until August 2009, so no it should not have been replaced last year.

What happened last yr?
3800 was replaced with the 4000.
The 7000 was discontinued in Nov..
The 9000 didnt come out til March.
It would have made sense to come out with the Replacement for the 6800 at the same time.
Regardless it is Coming....Cant Wait...
post #972 of 1120
The 7800 I believe is DLP, is it not?
post #973 of 1120
If they can do power lens shift, zoom, and focus like the HC6800 with DLP instead of LCD for around $2K I'm going to be tempted to sell my HC4000 and move up!

The 7800 looks to be a good one.

That would indeed be quite the temptation but I do not see how it could be close to 2K with power lens shift, zoom, etc, & DLP + 3D - I would say impossible. I will wait a year at least for the price to come down before I move up but it sure sounds like another winner.

Looks like its due out in October this year.

http://www.audiovideohd.fr/actualite...hi-HC7800.html

update: price is 2900 euros - little over 4K just as I suspected,,,,well over 2K

The bigger question is if it has the 2.35 "hidden" feature? If so and with DLP, that's going to be a huge success!

Does the HC9000 lack the "hidden" 2.35 feature? If so, that will unfortunately be a major let down if that's their new direction-At least for me.

Edit: Just read through the HC9000 manual, and it appears the feature is not present. Hopefully the HC7800 will have it. If not, the HC4000 and HC6800 are sadly the last to have this very awesome feature.
post #977 of 1120
I am looking at the 6800 for my room (13w x 17l x 9h). Obviously, the undocumented 2.35/1.78 feature is attractive, but can I still do it if I am at the extreme short end of the throw? Would be a seymour av AT screen.

I can mount the proj no more than 15.5 feet from the screen so looks like I can just barely do a 130 wide, 55 inch high, 2.35 screen at that distance according to the proj central calculator. That 55 inch high screen would be only a 98 inch wide or roughly 113 inch diag image when projecting 1.78 content.

Am I thinking about this correctly? Would this work for me? Thanks

Does anyone have there 6800 on the flush Mount from Mits and if so how do you like it...

You don't find it in the HC4000 nor HC6800 owner's manual either. This feature has been an undocumented for awhile now.
post #980 of 1120
mjg100 -- It's not documented, but it is shown on page 25 (menu operation table) of the HC4000 owner's manual - under the Image Menu, Advanced ==> Screen Size.

StevenC56 -- You are right. The equivalent manual pages for the HC9000 are pages 30 to 33. The "Screen Size" choices are not there. The HC7800 manual is not available (as far as I could find), so we don't know if they dropped it for that model. If the HC7800 is using the same electronics as the HC4000, then there is a chance that they kept the undocumented 2.35:1 feature (we can always hope).

mariokrt64 -- DIY BOC (your post #962) -- see the DIY section of the Screen Forum. Sorry for the delay in answering.

Davecraze -- As long as you can display a 16:9 and/or 2.35:1 on the screen, you can use the "undocumented 2.35:1 feature". Your 2.35:1 screen dimensions are wrong. A 55" high, 2.35:1, screen is 55 x 2.35 = 129.25" wide (= 140" diagonal). You may be using the PJC calculator incorrectly.

What about my question with regards to the Mount?

Sorry, I don't ceiling mount , so I don't have any info. It should be discussed elsewhere in this thread, or someone else can chime in.

The mounting holes are shown in the owner's manual.

Question for you CT,
will you jump ship to the new model later in the yr or wait and still keep your 6800?
New model is dlp vs 3lcd...

Glad to see you back...I did test with my current setup, and a 115 diag, 2.35:1 screen may yield a less than I like brightness...so I am not sure...may try a smaller size......Also I tried to mask the sidebars with my current dark navy blue curtains (very dark) but I am still able to see some reflections of the gray bars...which kind of surprised me....

fraisa...I think CT has a 5500, not a 6800.
post #986 of 1120
^ I'm pretty sure CT has a 5500 as well. I wish Mits would cross breed the 6800 with the 4000. DLP pop and sealed light path with motorized zoom and focus. That would be sweet. I'd switch to a 6800, but I'm sure the black level and overall picture would not be as good as my 4000.
post #987 of 1120
You are right guys, I have a HC5500. It throws a beautiful picture, even though the black levels could be a little better. It's also been totally trouble-free. I'm at 3200+ hours, all in the low lamp mode, with nothing but filter cleaning for maintenance (I have calibrated it twice, too). The lamp has degraded a little, but not significantly (estimated about 10% max).

After reading about the problems with the current PJs (including the high end JVCs). I've decided to keep using my current PJ for another couple of years, and bought a spare lamp. Hopefully, by then, there will be some real improvements in PJs.

StevenC56 -- Your HC4000 is the only real alternative. Maybe the new HC7800(?) DLP will be better, but we have to wait and see.

mariokrt64 -- Even though your curtains are a very dark navy blue, it sounds like they are not light absorbing. Light absorption is much more important than the color. Even black velour material can reflect some light, if it's not the right type.
post #988 of 1120
That's an excellent point........although they are very good at blocking outside lighting, they are probably not so good at absorbing it..
post #989 of 1120
Everyone,

I have the ability to buy a HC6800 demo projector for $1K. It has about 400 hours on the bulb. They tell me it is the original bulb.

They fired the unit up and it looks beautiful. It has been ceiling mounted the whole time, so it is blemish free.

Is this a good deal? Would you buy a demo unit, at $1K, to get this projector?

The HC6800 is not really bright enough for a 122" (115" 2.35 is equal to 122" 16:9) 1.0 gain screen. Best mode with normal lamp and mid zoom only gets you 13FL with a new lamp.
