Here's a small teaser screenshot. New 13ft 2.40 wide screen!
Everything dialed in, except for grey scale/colorimetry. These HFQ900 lens are uber sharp.. thinest lines I've ever seen, edge to edge! More to come tomorrow.

That's funny really when you think about it.

It started with the select few of us that actually had a CRT projector. People oohed and aahed over composite video on a 6' wide screen with 450 lumens.

Then some elitists added a line doubler. 480p, HOT DAMN!

A few years ago, people were bragging about upgrades from ES to EM focusing sets.

Then people were bragging about getting a 9" set.

Now that's not even good enough, the blender/stackers need to brag about the biggest screen size.

Gotta love it!

Great job Gino!

Congratulations, Gino! No matter how many times I look at the picture, I still can't quite seem to grasp the scope of the projected image.

How are the projectors placed in the room, and what sort of throw angle are you using?

Nice work; what PJ Height and Width are you running? Is it still punchy? :-)

Nice one GINO!!!

Some questions:

1. Is it punchy? Would you go even a bit bigger?

2. What screen material? SMX? Gain?

Regards!

Yes, Maximum raster usage with this setup. Actually, I think it was after reading your posts Nick that convinced me that you really need to go 2.35/2.40 to gain maximum benefits with blending.

Thanks Slarti. The projectors are floor mounted, 10 degree inclination. 113" throw. If you actually brighten your monitor, you can see where the projectors are positioned in the picture. They appear towards the edges of the screen, but they aren't that far apart, it's all perspective. They are a good 45" apart though, perfect since my centre channel is angled upwards from below screen. If you've tried floor/table mounted blending, the projectors can be in your line of sight. So I've built a stage 17" tall immeditely behind them, so they are unobtrusive.

Tim, screen is 65" x 156", each projector doing 65" x 86" with 10% overlap. I've only moved the Ultra's back 3 inches from before to fill the screen, so there'd be only a slight drop in light output in 16:9 mode , but because of the increased raster usage, it is brighter in 2.40.

It is super punchy in 16:9. Best I've seen it. When in 2.40 mode, it loses some. This is because you need to zoom in on the picture to fill the screen since your feeding it 16:9. So instead of watching 1080 horizontal lines, you're only getting 800 horizontal lines, which are stretched. I'm using the VP50 to achieve this CIH setup. Because of the reduced lines, I'm feeding 1600x1200 to each projector. If I move my viewing position back by another 1', the punchiness is back, so I think I'm going to move the stage/seating back some more.

Andres, see my reply above. No, this is the absolute maximum I'd ever think about going. The projectors are still running comfortably, and still have a short throw with this setup. Any wider, and you'll start losing that light output and have to drive them harder. The new HFQ lens really help going this size though, so I suggest you start looking!

No, not SMX. Even though by all reports this is a very good material, I am not in any need of perf screens. My speaker designer made the front speakers so the sound imaging still feels like it's coming from screen centre, and not below the screen, so it works a treat already, without compromising sound quality. Wanted to keep this audiophile grade

It's 1.0 Gain, and its amazing how much light is still coming off this thing. My belief is raising the screen gain means raising your black levels too (so worse On/Off CR??... darin??) In any case FTB is awesome, with no sign of the blend. Thanks Cliff for showing me this can be done.

Try this. Go to Image Main, confirm that the Aspect Ratio window says Zoom then click on the Zoom tab above the window, a slider on the right enables further scaling of V Size and should give you full 1024 lines. Reduce the projector V Size and fill the available raster, then correct the projector size if needed.









I was able to take 2.35 to the full raster height as seen here, using all the scan lines of 1024p instead of 3/4th of the scan lines. With greater projector H Size and wider spacing like you now have, it should even out, I did not elect to move my entire room to prove the point :-)

Tim, I think you misinterpreted me. By saying I had to zoom in the 800 lines, I'm referring to the actual source material. 2.40 aspect from 1920x1080 source, only gives you 1920x800... or the 800 horizontal lines. The DVX then upscales this for me to 1200 lines, more than 1024! So I'm not seeing scanlines, but I'm seeing more of a scaled image versus 16:9 material... do you understand?

My Blendzilla is bigger than your Blendzilla seriously though, looks like Gino has taken it as far as possible with only 2 9-inch projectors. So who's going to top this one, 3 x 9500's in a curved virtual reality set-up that wraps around the room like a flight simulator.

If you are happy then so am I, Zoom x Zoom is a capability that is not really obvious........ :-)

I told you so Andy! I said, build a bigger room! But seriously mate, thanks very much for the HFQ's. There is no denying they are super sharp. Thinnest lines I've ever seen (mind you I really dialed in the magnets/astig better than ever), but the focus is so sharp now, from left to right, and this really helps at screen centre!

Gino, I do not understand how 16/9 can be punchier than 2.40:1. I understand that with 16/9 you are effectively projecting into a smaller screen, but the tube face used is also smaller, right?

Yes Andres, raster width is less, as it is CIH setup, raster height is same. BUT, with 16:9 material, my source is 1080 horizontal lines. With 2.40 material, my source is only 800 horizontal lines (the other 280 is just black bars which are cropped). 800 is less than 1080 obviously, so less info... less punchy.

OK - so you mean crispier, right? I thought punch = constrast and dynamics, now I think you mean more resolution/definition.

Anyway... more pics???

I'm sure if I had to live out my days with a video grade, 7", ES focus, air coupled, CRT FP with analog convergence board and a laserdisc player with a bunch of LD's.. I could still be thankful for it and happy about it, kind of funny like you say.

Gino,

Nice. Thanks for sharing and good job with making it shine.

Looking good.
But what's with the bright walls? Can't you hang up some curtains or something?

I'm waiting for someone to come up with a way of blending three projectors. I've got three 808LC's I'd like to try that with. =)

Awesome Gino. If you want, email the pix right to Kal, I'll see if he can rearrange the opening page to put a couple of the pix up. If you can get a good shot of you standing in the projected image, that would be great. You've posted one, but you're kinda in the shadows...

Conceptually you could set up projectors vertically so that the raster is 3/4, use the VLC plugin that allows for more than two projectors (and customize it slightly to rotate the images as well), use ~20% blend zone; and have a nice 16/9 setup.

Easier said than done....

You're a hard man to please Ken.

There's a tonne of acoustic tiles and curtains around the room, and 16ft cathedral ceilings, 24ft x 28ft room, fronts angled up towards listening positioning, rears a good 5ft off the ground. Suprisingly the room isn't live at all with the tiled floors! As for the white walls, still thinking about how I can hide them, as I said earlier, I'm only renting atm.

Yes, I like that too, it also means centre channel is pointed directly at you. But the projectors arent in direct line of sight anywhere you sit, I built the platform high enough that you get 6" clearance on top of them.

Hi Gino,

My suggestions would be as follows.

1. Invert the bass speakers, port to the floor.
2. Acoustic matt directly infront of the bass speakers.
3. Place the front left and right on TOP of the bass - they are too low even if angled - they should be about 2/3 of the way up the screen.
(That will also give you a better point source)
4. Always difficult but center ch should be up top facing down - difficult one.
5. felt around the ribbon and tweeters on the Front L,C,R.
(the low mid drivers look like audax drivers - I cant tell the rest.....)

Im guessing you are running sub Left and Sub right, not one LFE channel.

IF you are running one LFE (.1) then when you move in subs want to be together, maybe on their sides under the center speaker.

If you are running LFE then try seperate Left and right - if you can........


These are just my opinions, and I would like to hear your views if you changed anything.....

Every audio engineer will have a different opinion.

See if anyone out there agrees with me.

(I have not given my reasons for any of this).

Andy.
