For me, having plenty of light adds to the dynamics of the image. I'm betting that you will get a much better image overall with 12.5' rather than 15'. What is the distance for your front row ?

A bit smaller was my next recommendation but you found it anyway.

Art - the distance from the front row is now 3.4 meters, so I am still closer than 1x screen width.

I have just watched Serenity in HD-DVD... OH MY!!!

Serenity is one of my favorites. I made sure it was among the demo stuff I showed Gino on Friday.

One of my coworkers worked for IMAX I guess the screens cost about 1 mil or so. He told me the specs of the setups before can't remember all of it. But Just think 10 18" subs in cement lined boxes. oh that would be amazing to have in a home theater. Oh wait that's about what Art has

How wide is that room looks huge.

No, it is not as big as it seems. The room is roughly 6m wide by 8m deep.

WRT to subwoofer, I am using 4 x 12" in the form of a Genelec HTS6 (btw, Gino: I had the C channel connected to the sub... go figure... )

Hi Andres, I'm glad you decided on this. As you know, I like to sit slightly further back than 1 screen width for this reason as I told you, less strain on the eyes, can see more of the picture and it's still in your face, and the sharpness is better. I also felt you'd do better decreasing size, but I assumed you wanted size above PQ. Now you see why I limited myself to 13'. Things are even brighter and punchier!

Thanks

You use optical for DD and DTS and analoge outs (3,5mm into 2 RCA) for TrueHD? Did you maybe compare sound to stand alone unit how do they compare in sq?

Right now I am using analog out (5.1) directly to my Denon AVC-A1XVA (akin to the 5800MKII - I think) in "pure direct mode" so the Denon acts mainly as a pre-amp, sending the (analog) audio to the Genelec DI8A (unbalanced RCA to balanced XLR converter) and then to the corresponding Genelec amp (each of the L C R speakers has its own -callibrated- amp, the sub and the surrounds have built-in amps).

To be honest I have been unable to do much setup/testing on the Audio side. The Denon has something called Audissey for room correction and comes with a mic to do measurements; but I have not really tried it yet.

The one thing I will try soon is to just bypass the unbalanced->balanced conversion for the sub. The DI8A is spec'd at -/+ 1.5 dB at 18 Hz so I will run a straight RCA cable to the sub to see if the very low end of the HTS6 is affected by the DI8A freq response.

My main focus right now is:

1) Try to revamp one of the new LCP tubes I got (BLUE) which as advised by Terry could have some dirt in the gun (it showed retrace lines). I am right now using a 9+ blue tube I got, but I really like to run the PJs with as much identical components as possible.

2) Get one of my MPv2 VIMs fixed; and find out if some vertical lines at the left of the screen on bright scenes are caused by the other MPv2 VIM.

...and I need to do the above before ceiling mount the PJs....

Hi Tim,

I will post some pics of the vertical lines probably tomorrow.

For the time being, here's some additional screenshots of the blend at 15ft:







I really need to get some practice making nice and FOCUSED pictures...

The last one is a computer game (Far Cry). One thing that has really amazed me is the speed of the CRT and lack of any movements artifacts. My HTPC is good enough to run most if not all games at 1920x1024 @ 72 Hz with VSync enabled so the quality and fluidity is amazing!

The first Marquee is being ceiling mounted as we speak! We used a "kind of" unistrut method with the locally available stuff, looks very nice and the PJ doesn't need to be "railed in" just attached to the top struts in place.

Work in progress:


More pics will follow tomorrow.

Now I need to put the replacement blue tube I just received from Terry, and prepare the other Ultra for its lift to heaven... Then more painting work to be done to the white Ultra and the rails...

Hi guys,

Some updates:

The two PJs are ceiling mounted now, and the room looks a bit better:



Things to do next:

- Put new blue tube received from Terry. THANKS TERRY!!!
- I am waiting to receive my Special 02P VIMs from MP and then I'll redo setup again.
- Then neck boards. Setup again.
- Frame screen with blackout material
- Run it for a while
- Cover the projectors with black painted covers (already painted them)
- ... NEVER touch it back until something that significantly beats this setup in all areas shows up... :-)

Oh!! How right was Gino when he told me that you really need to become a MASTER to do this right.

Wide-angle lenses tend to distort things. I'd say the room has about 48 sq. meters. Not that big, but just enough :-)

Ok, that's it. I'm gonna move out there with you big dog. I'll bring the G90's and we'll do a quad stack/blend.

That should cover about a year and a half rent!

It DOES look huge! Maybe it's "only" 48 sq meters (that's "only" 3x bigger than my HT) but how high is the ceiling? You must be aiming those 'Quees down quite a bit! It looks like they're at least 3-4 meters off the floor?

But I'm still agog at the screen shot with you in it, Andres -- either you're about 1.2m tall, or that is a freakin' GIGANTO screen!! Holy #%# !! How big IS that thing?

The screen is 5m meter wide. That shot with me was done when Gino was here, and we were running 5m wide... the problem was that it was way to big for the first row (I remember we saw House of the Flying Daggers and I could only focus on the subtitles... ).

I have reduced the size to 3.8 meters wide right now. VERY BRIGHT and almost ideal for me to watch in the first row (some people prefer the second row).

The PJs are mounted using a method very similar to Unistrut. The tilt is not really much, and I made sure (as per Tim's instructions) that the lenses (HD10Fs... FINALLY!) fall under the screen area.

The ceiling is a bit higher right after the PJs (60 cm higher).

I did a grayscale tracking yesterday but I got very odd readings (blue drive at 15, so everything looked wrong)... then I found out I hadn't removed the "baffle" of the Spyder 2 for the readings... go figure. I'll redo everything this weekend if time allows.

CLIFF: Absolutely! You are invited here for your world CRT tour! Just make sure you do not bring guns with you

The one thing I'd like to say is that if you haven't seen 1080p @ 72 Hz you owe it to yourself to try it.

Those stacking or with single 9" that can do 1080p @ 60 Hz but start to blur at 72 Hz, try doing 1920x800p @ 72 Hz (for 2.40:1 movies) and maybe the PJ would react better.

Dear Andres;

I also would llike to come visit you sometime. My luggage will be much lighter than Cliff's. I won't be bringing any 9" CRTs with me!!!

MP and I are about to start completely redoing the Virginia BlendZilla setup, for the East Coast BlendZilla Meet Part Deaux, to be shown at a personal IMAX far away from you, on 2007 October 20. You are cordially invited to flit across the pond, and pop on in.

Mike and I start by taking both projectors down. The left one gets a brand new blue CRT, and possibly a contrast board. The right one gets an upgraded CLM, HDM, convergence and possibly a contrast board. I ended up with a 12 foot wide 2.35 : 1 SmX acoustically transparent screen. Not quite up to your standards, but not too shabby either.

I completely agree with you on the 1920 x 1080 @ 72 Hz thingee. My goal is to have all sources (HD DVD, Blu-ray DVD, ATSC tuner, legacy media) input 1920 x 1080 @ 72 Hz to the DVX-8022, and the DVX output ~1150 x 1080 @ 72 Hz to each Marquee. What say you and Gino and I (along with the guys in Phoenix) start a lobbying campaign with Analog Way to upgrade the firmware?

William

I enjoy mowing my lawn. It's the only two hours of my week where I know what's expected, understand the job, can forsee completion, and look back and see progress.
