The projector budgetary, therefore is required the jeweller approach.
Filter ND will lower brightness to comprehensible value.
It is necessary qualitative ND.
Recommended the filter of firms MARUMI and KENKO.
Filter HOYA is not recommended. Colours changes.

Thanks, BKSRU!

I am an amateur photographer, so I am familiar with ND filters. But I never thought of using one with a projector until your post here.

For those who feel their projector is too bright for their purposes, using a Neutral Density (ND) filter will reduce the brightness without affecting the color, although BKSRU says the Hoya brand does cause color shifts, so you may wish to follow his other recommendations. (Elsewhere I read claims that an ND filter also reduces the "rainbow effect" with DLP-style projectors.)

The ND filters are not expensive, from $15 to $150 - but most are at the low end of that range. They even make variable ND filters which would allow you to adjust the brightness as needed.

Certainly an interesting option to try if excessive brightness is an issue for you.

It is difficult to communicate.
I hope you me understand correctly.
I understand .

There is no sense to take expensive filter.

Qualitative MARUMI and KENKO.
The price 15$ - 20$

For projector Epson 705HD
- Screen MW + ND4
Or
- Screen HCG + ND2

For comparison:
Epson 720
http://www.projectorreviews.com/epso...erformance.php
Theater Black 1: 371 lumens - This is technically the best movie watching mode (and quietest), although many people who are not perfectionists may prefer slightly brighter modes that do not sacrifice significant picture quality.
Epson 705HD
http://www.projectorreviews.com/epso...erformance.php
In "best" mode - in this case Theatere mode, it is definitely the brightest of any 720p projector we've reviewed in recent years. In Theatre mode we measured a dazzling 1217 lumens, which is more than double the average brightness for best modes. After calibration, brightness dropped an insignificant amount to 1201 lumens

Superfluous brightness spoils level of the black.

Yes, I understand, a $15-$20 filter will do fine.

And you suggest using ND4 with brighter matte white screens and the ND2 with high contrast grey screens. By using the ND filter to lower the brightness, you hope to improve the black levels.

Thank you very much for taking the time to share this information!

Depends on the size of the screen and premise preparation.
ND2 1200/2=600 lumens
ND4 1200/4=300 lumens
We look recommendations AVS.
It is a pity is not present ND3.

I do not hope. I know .
Not only level black to improve. Colours to improve.
It is necessary to result in norm: Brightnes/Level of the black/Flares
We put the filter and we will move further .

I have a Da-Lite High Contrast Matte White screen and I am concerned about the brightness and contrast of this projector. It has shipped, but I don't have it yet. So with the HCMW screen, which filter is recommended? From the above post I'm not really sure if you mean that I should be using the ND2 or the ND4 filter. The HCMW screen is a light grey colour (not really sure why they call it white...) Also, for this projector what diameter should the filter be? I really want to achieve better blacks than it is capable of out of the box. Thanks for your help.

The filter of 62 mm looks solidly :

62 mm:

But it is possible and less.
I on your place would take ND4 and ND2
It is useful. The price is not high.
Besides I do not know the size of your screen and a blackout condition.
And here jeweller work is necessary.
But it will give an excellent picture for 700$ .
There are also other recommendations.
I can give the small review Epson 705 vs Optoma 65.

From the screen HCMW there is not enough advantage. It really a light grey .
For this projector it is better to use screen HCG.

The problem is I already have the HCMW screen - I was using it with my Sanyo Z3 before it died. Are you saying that the ND4 filters will not help the contrast levels with this screen? I really don't have the budget for a new screen at this time, so it will have to do - even if it is not as good as HCG.

ND will help with any case.

I simply speak about the best combination.
Probably I am difficult for understanding.
Buy ND2 and ND4.
Experiment.

What at you as a player?

I understand. You know from your experience that this works. You expect to make further improvements.

You mention no ND3. Have you considered using two linear polarizer filters? This would create a variable ND filter that can be adjusted. This is an old trick from science class and used by film photographers many years ago.

You can get the linear polarizer filter very cheap. (They do sell variable ND filters, but they are expensive ($100-$300).)

Should be a fun experiment to try.

You already will have some control over brightness and contrast in the projector itself. You can set the lamp mode to low, use the Theatre color mode, and there are brightness and contrast adjustments via the menu. You may get a perfectly acceptable image just using this. It's certainly the place to start.

The brightness settings control the opacity of the LCD panels, effectively a built-in in ND filter. The ND filters would simply take this a big step further as far as reducing brightness. But a lot will depend on your setup, screen, distance from projector to screen, source material, ambient light in your room and so on.

But I would not go into this expecting you have a big problem with brightness and contrast until you set your projector up and see. Then you can decide how far you need to go to tweak things. As you can see from previous posts, a lot of people are happy with just some minor adjustments.

The ND filters are an interesting way to improve things. But in some situations, this projector's brightness may be an asset. The only way to know for sure is to experiment with your setup and see.

Good luck!

Thanks for the advice, I'll definitely try it out and let you know my results. As for my players, I have a Panny BDP-30 BluRay, Toshiba HD-A20 HD-DVD player, XBOX 360 and HDTV.

Thanks again,

I just got mine today. Very impressed coming from the HC3800 (seeing as this is a "downgrade"). No more rainbows is nice.

I find the clicky auto-iris to be a bit annoying. How big is the effect of turning it off?

It is a pity there is no computer in system. One more council would be useful.


Short comparison Epson 705 vs Optoma 65 (IMHO):
Epson 705 + ND:
Pluses:
The price
Good service
Good potential for improvement
Short focal length
Long service life of a lamp
Picture on parity with Optoma 65 (Epson 705 + ND)
The picture soft, does not press
Is not present RBE
Mobility, Compactness
Design accurate
The dynamic Diaphragm is almost imperceptible if to use with ND

One minus:
The dynamic Diaphragm rustles

Optoma 65
It is not reliable
RBE
You still want it?
Never considered Optoma 65 suitable for a house cinema

I thought over these, but did not try.
Actually standard ND suffices.
But the filter with small step of change would be useful to many projectors.

Adaptive -
I turned mine off and have not notice a degradation in the picture. It is a quick test for you to see if it affects your environment.

I run mine with the iris off too. Not really noticeable difference. I am really loving this projector. The brightness is amazing. Love watching with some light on (not a natural cave dweller). I will take the brightness over black level any day, even though I am good with the blacks now. Guess that means I'm not a true theater snob.

Hey how did you get that many hours on your bulb, they are only rated at 2000-3000 not 4000, did you get a special bulb or something. Is there another better bulb that I'm not familiar with. My bulb went out at 982 hours, It may have been cause I had a lot of dust from doing some woodwork.

I started a new thread about using a 705HD in a small room. After re-reading it, I think it should actually be in this thread. Here it is in slightly modified form:

I have room enough for somewhere between an 85-92" screen depending on if I go with 16:9 or 2.35:1. From looking at projectors dimensions and clearance, it looks like I'll have between 8.5 and 9' between the front of the lens and the screen. I'll most likely be using this for outdoor movies a few time a year, so brightness would be good. The room is also not going to be painted black (or nearly black), as it's also a den. I'm not opposed to painting it darker, though. Lightwise, it will be fairly dark and can be totally light controlled - no windows. I'll probably mount a shelf on the back wall for the projector; it'll also be over my head (couch is against the back wall).

How would a 705HD do in this room? I know this projector is said to be bright, but will this be a problem in a room with some reflection? Price, both of the projector and of bulbs, is a major consideration. I've been looking at some used projectors locally in the $175-200 range, but all are 480p. I think I'd want better than that, plus, with unknown bulb life, I think I'd be better off with a new one with a new bulb and warranty. Are there other models I should be looking at for this application? Thanks!

Looks like you throw distance should be about right for the size of screen you are wanting. This thing is very bright. Should look nice outdoors. This projector is designed to be a multipurpose projector for movies, games, tv, outdoors, etc. I wouldn't sweat the color of your walls, etc in you room too much. Since it's not designed as a dedicated home theater projector, I don't feel those things are as crucial as if you were forking out $2000. I have a white drop ceiling with medium pine walls with semi gloss poly and I am quite happy with the picture. I don't even think about reflections and such. It basically throws up a nice, bright, decent image about anywhere. I would probably ceiling mount it as opposed to a shelf mount if you can imo. I used a cheap $15 one from monoprice and it worked quite well. Mine is mounted over my head and in eco mode with the iris off it is pretty quiet. Turn those on and the noise does increase though. If you read the projectorreviews.com review, he basically says that this is a great projector for those wanting a large picture with minimal hassle. It's great for family rooms, living rooms, dens, outdoors, etc where a controlled environment is not available. It will look much better than the 480p projectors you were considering. Epson's warranty is top notch and the initial cost and bulb life are great. I think you would be pleased. Just keep in mind that it's not a dedicated home theater projector so if you are a stickler about black levels and such, you may want to look elsewhere. I don't think you can find better performance for the money, though, and that is the thing to remember if you are on a budget. I would take it over an Optoma or Mits any day.

Thanks for the input; that's exactly what I was wanting. I'm sure I'll be happy with the black levels. After 10 years with a 53" non-HD, non-ED RPTV with convergence that won't properly converge, anything's going to look great! It looks like I'll be ordering one soon.

I'm having trouble understanding your meaning. Are you saying that; it is possible to get thie projector to look as nice as a Epson 720? Or Are you saying it can't?

The necessary has allocated. It will be subjective on one parity.
There are even ways to correct a situation to the best.

Epson TW450 the European analogue Epson 705.
Office variant Epson W8. It is cheaper. Possibilities actually the same.
Epson W7 the same variant, but is not present HDMI. For some it is not critical, who uses the computer.

Your office analogue Epson EX71. Black colour approaches for a house cinema more.

The Epson-EX70 (analogue Epson Home Cinema 700) - old model. More silent.
