|
|
Hi There
What do you guys think about CIH on a CRT setup?
What would be the best way to do it, single projector squeezed, double projector blended image or a projector per Aspect ratio?
Cheers
Willie

I tried a stack but now stick with only one single projector. A scope screen looks so much better than 16:9. It is like switching from 4:3 to 16:9.

At the moment I have a Barco 701s HQ but was hopping to buy a pair of NEC 6/9s in the future for this.
With the blend setup do you then run it as a 21 x 9 aspect ratio with a pillar box configuration for the other aspect ratios?

Yes, in a blend i run 1064x800@72hz to each Projector. the blend zone is 208 pixels between PJ. This works very well.
The hard part is matching Gamma , Greyscale, and CMS. Gamma being the most important between PJ's.
Tube wear on Both PJ's should be close and hopefully you'll have two PJ's that have 4x3 wear. If not find tubes that match closely.
For the other aspects like 1.78 you have black area on each side. I hardly ever watch 1.78 and if I do i just leave it as is and what ever gets cut off top and bottom gets cut off, it is what it is. It doesnt bother me, I watch Avatar this way and really cant tell i am missing anything, some do the 1/3 by 2/3 crop for 1.78. 1/3rd from top and 2/3rds from the bottom. That is actualy
nice for 1,78.
There are lots of things you can do. If you love to tinker and dont mind playing around do a blend. If you want to get it set up and watch movies right away, stack PJ.s

Blending is an ideal choice for a CIH setup as it maximizes the strength's of crt's and deminishes the weaknesses.
The PG series of projectors is somewhat bandwidth limited, so blending completely solves this.
Also, you will have a considerably brighter picture blending rather than stacking.
Your PG's will have a rough time resolving HD material with progressive scanning if you stack. With blending, it will be very easy.
If you want to easily be able to switch from 16:9 to 2.40 sources, you should probably use an additional scaler before your signal is split to do this, I agree with Nash, that once you get used to 2.4, anything else looks bad by comparison.

Thanks guys
If I consider the cost of blending doing a stack might work out more affordable
With one projector closer to the screen for 16:9 and one further away for 21:9
Or another option:
I notice on the settings of my Blu ray player that you can select the TV - Type as 21:9
And then set it to ouput all other Aspect ratios as pillar box.
This might mean I can get away with one projector squeezed down to 21:9
Will this work? will I sacrifice image quality on 16:9?

Sorry we posted at the same time
Looks like I'll have to save up or troll the classifieds for good price on VP's and blending gear.

I was hoping to do this in bits in pieces in the next year or so
I always plan long in advance
I'm not in a hurry at all.
The current price on NEC 6 PG is between $900 and $1500 that without shipping which cost me about $500 with the last PJ about 3 years ago. That pegs it at $3000 plus just for the projectors.
A quick look on Tv One's site revealed the B-stock price to be about $2000 for a C2 7100
That's an estimate $5000 plus not taking other adapters etc in to account.
So basically I don't have an endless supply of money but am willing to invest over time.
If i can save by buying the gear second hand id rather wait and do that.

Thanks for all the info and the offer for TV one products.
Would they work with an external moome Card?
I was thinking of buying the moome card cause I need to force negative sync for the Barco. To whatch Blu rays.
Would be nice to get a VP now that would work with the Blending gear later.
Cheers

Yes they will. But i use the Moome MUX-HD that removes all the HDCP crap. Then you could use an older
Lumagen Vision HDQ/HDP to force negative sync. those are cheap right now. two New in box HDQ's just sold on e-bay for 225 USD. They have 11 point gamma and greyscale and RGB CMS. They do work for Blending pretty well but not as well as the Lumagen Radiance which has Full CMS( Added CMY).
