They both look very good. But I don't recall getting the hit you in the face with the 3D contrast that I get with the H77. Maybe because it's brighter. Don't forget the reds also. About the Optoma's scaler vs the Faroudja scaler, I disagree this scaler deinterlacer does everything the Faroudja chip does. It doesn't miss a beat.

Still a tuff choice. I like the tune up idea on the Marantz but don't know how well it works. I really like the motorized zoom and focus on the H77.

So youre saying the H77 is brighter? If so, is it to the point that you could get away with more ambient light with the H77 than the marantz?

My HT will be completely dark for movies but sometimes i may have friends over to hang out and watch sports and may want some lights on if people are eating, etc. If the H77's brightness might make it possible to have more ambient light in this capacity i would consider that a plus.

I probably wont be using the scaler in the PJ since ill likely be doing that before it get there.

Whats the 'tune up' on the marantz? Is that the auto calibration thing?

Thanks for your insight here. All of your comments on this thread have been very useful.

Yes the H77 handles light in the room very well.

The 12s3 comes with an item you put on the lens that talks to the projector and makes color adjustments to find 6500k according to the room environment.

How well it works, I'm not sure.

Greg Rogers, in his WSR review of the S3, found the auto-calibration to work pretty well with very flat tracking at 6600 K until 20 IRE when it went to 6800 K reaching 7400 K at 10 IRE. He manually calibrated for better tracking at the lower IREs.

Then it's very good. You know it's hard to track under 30. Neat trick

But no power zoom & focus.

Someone asked about the filter. The filter can be hand cleaned and re-used. How often, it's up to how dusty the enviorment is.

Tom,

Thanks for the info regarding the filter. That was me. I'm "inches" away in getting/buying that H77.

The filter is really just an extra protecjtion because the projector already has sealed optics.

Pick one up, you can see how once the projector was out in a few places other respected members were seeing things just like I did.
Great picture, great price.

Tom,

What is the effect of altering the RGB values for brightness and contrast individually? Is this a useful way to get closer to D65 gray? If so, what did you use to measure the color temperature? Also, any advice you might have for how to do the testing and adjustment would be welcome.

I am into digital photography and already own a Gretag-Macbeth Eye-One photospectrometer with general purpose software that allows me to measure color temperature of light sources. However, I have no idea how I might use it to fine tune gray scale on the H77. All advice welcome.

Thanks,
Ira

Steve, it's clear on my $99 monitor.

R-contrast 8
G-contrast 7
B-contrast 7

R-brightness 3
G-brightness 3
B-brightness 3

Ira, I used my eye and increased the levels to open up a bright picture and balance the grayscale trying to make facil tones to what I remember 6500k looking like. I sold my Colorfacts system some time ago that had the one/eye.

What you do with you software and one/eye is run Avia'a full screen IRE patterns. Black to shades of gray to white.

Use RGB-contrast for 50 and above IRE levels

Use RGB-brightness for 40 and below IRE levels

You want each IRE pattern to put the Red,green, blue at the 6500k line. Best way to start is to bounce between 80Ire over to 30IRE, work you way in between.

Then try to fine tune the 90 & 100ire and the very low 20, 10 IRE. It's tricky you just keep checking the lows and the highs.

Usually it's very hard to line up 10Ire and sometimes even 20, so don't worry too much about them. If you have a fairly good tracking from 30 to above that could be good enough.

Will the h77 do 1 for 1 pixel mapping over DVI and or RGB/Component? I would needto override the internal scalar with an outboard one.

And just to confirm, this machine does have all the same DLP parts of the Sharp 12k and Marantz S3? Ie HD2+, 8 segment color wheel, ect...

Yes it does do 1.1 with my Bravo over DVI, no overscan nice clean picture.

The H77 has the HD2+ dark chip. But it has double dark green segments making an 8 segemant color wheel. The Sharp and Marantz have one dark green segement making a 7 segment color wheel.

As far as I know, the H77 (and its likely clone from Mitsubishi) are the only HD2+ units that use an 8 segment wheel. The others use 7 segment (most of them) or a 6 segment wheel (Benq 8700+).

8 segment design? Maybe this is why it's looking better.

Balancing one dark green between each of the RGB sections. We always like balance don't we?

So you guys didn't notice anything unusual about the first two Gandolf and Frodo exchange pictures?

I forgot I had the Bravo set at 4.3 because I wanted a full 16.9 frame for a test I was doing. Made the image squashed and I use the Letterbox aspect to stretch it. It shows a taller image.

The shots after that I reset the bravo to the correct 16.9.

It's picture quality is the real surprise. There's been a haf dozen or more members here that reviewed or had a look and all comparison reviews put the H77 at the top.

If you're planning on picking one up, talk the AVS, they have the best deal I've heard of and they're in line for quick shipments.
good luck

Took some 3D shots this morning of my favorite movie opening credits. My wife thinks I'm nuts but I could watch this intro a million times.

These taken with the PJ in Brightness mode using the Pany XP30 in progressive.

I have an Optoma H30 also and consensus is it's an extremely bright projector. Here's a comparison. Same DVD player & screen gain (Mat White).

106" diag Mat White because that's what I've had around lately. Better choices are the Cinema Vision or High Power. CV if you go tensioned, HP if not.

Well I just couldnt wait for the carpet install tomorrow, so I went ahead and put the screen up on the frame.

I have a 119" Da-lite CV screen with the velvet border. I love the border, it eats any extra light and you cant even tell.

Well the H77 on the 119" screen, looked great. I watched Starwars II in HD for about 10 mins, Star Trek First contact also in HD for about 10mins and Entrapment on DVD through the iScanHD SDI output.

The colors were solid, the screen door could not be seen by me after 7ft(first row of seating at 16'). There were no rainbows for me.

I also watched Discovery HD of a flower garden and I mean I thought I was there )

I did also watch the news on normal digital output and it looked good.

I will try to take some Screen shots this weekend, but have never done that before, so we will see

The bad thing was I went up stairs and watched the rest of the news on my 57" HDTV and it looked like I was watching a 13" TV, hehehehehe.
