Marquee 8500 with Sony Blu Ray player

post #1 of 11

Hi All,
It's been a long time since I posted but my home theater is finally almost finished.

I had been using a HTPC with TheaterTek with my Marquee 8500 anamorphic squeezed so I could do CIH. I just bought a Sony Blu Ray disc player. I don't know if/how I can use it and still do CIH.

If I run the standalone blu ray player directly to the Marquee using a HDFury2 or the Marquee VIM-FULLHD HDMI 1.3 Input Card offered at Curt's site is there a way to have CIH?

Or if I run the standalone blu ray player to the HTPC will I be able to do CIH?

Any other options?

I still plan to use the HTPC for TheaterTek purposes.

THANKS!!!!

You can do it, but you will be wasting a lot of unused Phosphor. The only real way to use all the phosphor and do CIH is to blend Two CRT projectors. I suggest you do CIW with CRT, at least for 1.78 and 2.40. I use a 12 foot wide 1.78 screen now and it works out fine. I keep all movies at 12 feet wide except the occasional 1.33 movies like Casablanca.

Thanks for the reply.

Blending is on my wish list but lack of funds is stopping me for now.

Two reasons why I'm trying to keep the CIH is 1) At 10' wide I may not have the height in the room for 1.78:1 films as I have a stage in front of the screen plus a center speaker. And 2) I intend to have a non-motorized valance across the top of the screen.

Isn't anyone who watches 2.35:1 movies without blending already wasting phosphor? Most everything I watch is 2.35:1 with some exceptions at 1.78:1. I can understand how I am "wasting" phosphor if I do CIH for that ratio, but is it really that much compared to 2.35:1?

Would I be able to do CIH for 1.78:1 by resizing and saving that setting in the memory for that aspect ratio?

Thanks again for help.

You answered your own question.

Test whether the image size controls have enough range using your current sources.


(What did you mean by "Or if I run the standalone blu ray player to the HTPC will I be able to do CIH?"? That's impossible. Put a bluray drive in the PC if you want to use the PC.)

I thought so, but I know that people here are much more knowledgeable than I.

Will do.

That's why I asked; to see if it was possible. And I don't think my HTPC has what it takes to run bluray.

Thanks much.

If what you watch mostly is 2.35 try this out ..... you might be able to put your 2.35 aspect ratio raster either towards the top or bottom of the tube. mark on the tube face where the bottom of the 2.35 image is then use vertical phase to lower the image in the raster to the bottom of the tube and see if you can clear the line you marked for the bottom of the image that was on the top if it clears your good , this way once this area wears out you can move the raster to the unused area and double the use of your tubes !!!
then set up another memory for 1.78 material , since you wont watch much you wont have to worry about that image area burning in but you might have a uneven wear line from the higher use 2.35 image.

Very good suggestions. I remember the first idea from when I used to read here, but I haven't been able to do anything with my Marquee in over a year (long story) so I had fogotten what I had learned. Your idea about 1.78 being under a second memory is something I wouldn't have thought of since in the past I was using my HTPC to keep CIH.

The more I think about it the more I'd like to blend. Anyone have an 8500 they'd like to get rid of?

Well, as an experiment I've run my BDP-S1/HD-SDI into a Decklink and scaled the input with Premiere CS4, so it's not impossible. That said, my CII is better suited for this task.

OK, I have read this now a couple times - let's just consider what the draw
backs might be, even if it is possible to obtain that much vertical shift, and
without difficulties using that much offset affecting the VDM.

#1 - This will really push the image off optical centerline, and you will have
a sub-optimal light output distribution (output drops exponentially with
distance from optical centerline)

#1a - With the image center so far off optical centerline, I would expect
increased difficulty maintaining optical and electronic focus and astig.

#2 - the image width may have to be reduced, the tube face is not perfectly
square, and the corners will likely not clear.

Obviously, experimentation is encouraged, and I would like to hear about
someone actually trying this, and their results. But from what little I know
about CRT setup. even if it could be made to work, one will be trading
one perfect picture that may last 5000 hours or more, for two considerably
less perfect iterations.

Gallen,I agree with the optical focus issue, I got this idea from Cliff after he commented on Gary M's 2.40 wear pattern on one of his tube pictures. In he following post to cliffs i stated that it would not fall into the center of the lens for best focus, but it still could be dont if you are not too keen on sharpness.
So how is your Secrete Project going?
