LOL.. I have a old Fujitsu 720P plasma in my bedroom.. Only have analog inputs. So i can connect my HD Fury 3 and the Radiance XS and play with that every night until i get my CRT back up running..

Is there anyone that can find a link for me about how to crop 2,35 movies to 800x1920 72hz, to save bandwidth, on radiance XS+
I was playing with it last night, and didn't get it right.

Update..
I have just been enjoying my CRT for some time with my new screen now, and there have been some issues changing from 90-110"
I lost a little sharpness to the image, and i think its the dirt i'm my glycol that have more effect on the image the bigger it gets.
So CRT image gets softer the bigger, and Digital gets harder the bigger it get.
I really enjoy the magic dept/ 3D i get to the image with the CRT it just seems so realistic.
I haven't had time to find out how to run 72hz with my lumagen yet, so i'm stuck with 60hz for now.
But if anyone have a guide for setting a 2.40/2.35:1 image up for 72hz with the lumagen ill sure try it out.

For 2.4 aspect you'll need to change out three resistors on the VDM. 704,804 and 904 from what they are now to 68KOhm's.
This will give you added adjustability to reduce the Vertical size of the image for 2.4 aspect movies.
So now you will be able to run 800px1920@72 on the lumagen HDQ. You will have to mess with the timings
to get rid of any ringing if any shows up. Also remember to keep H-sync over 1us or else vertical lines will have squigglies
every so often.

The resistors have been changed long time ago, what i didn't have time to find out is how the crop works, so i can limit the bandwidth on the lumagen and 9500, i need a H total on around 2400 to push out the ringing, so running full 1080P 72 hz is not working, its to much for the 9500 or the lumagen to handel.
Do i need to set the Radiance to 817P and then 2.35:1 on both input and output, and crop the top and bottom, or how i do.I got a bit lost, and just ended up with a pic with scanlines, guessing i got 817 lines over the full 16-9 screen, downscaling the image.
I imagined that maybe somewhere there was a setup list online, to make it easier for one new to it like me..

Well on the the HDQ i use 800p 817 adds scaling and most movies I have are 2.4. Plus it's a nice even number.
Id just set the lumagen to input 1080p@24 and then output 800p@72, let it figure out its own timing numbers first before
looking at changing them. 1080p out from a non + Radiance will not work i would think.
When using 800p there is no scaling, it is only allowing the lumagen to send out that portion of the image. the black area of a 2.4 movie or the 280 lines 140 top 140 bottom are not scanned.
But doing this will make the image to tall , so here is where you have to size the image down in the Marquee.

And just to add to this, I initally made the mistake of using the shrink function in the Lumagen to reduce the size for 800P. Swapping out resistors 704, 804 and 904 on the Vertical Deflection board allowed me to reduce the vertical height enough to accomodate 2.35/2.40AR material.
I ended up with an HTOT of 2320 on my HDQ to shift the ringing out of the image.
1) First set your HTOT to put more distance between the active image and the left edge of the raster.
2) Then increase your Marquee H-width to stretch the image out to fill the screen.
3) Use the green random access under convergence to shift the raster to the left. Make sure the right edge of the raster is just slightly to the right of the right screen border edge.
4) Finally, use phase function to center the active image (if done properly the right edge of the active image will be on the right edge of the raster but centered on the screen).
In short, you have placed the active image on the right side of the raster while shifting the raster to the left and thus moving the ringing out of the active image.
If you do not do this you will end up needing a much higher HTOT; thus wasting bandwith. At an HTOT of 2320 I ended up with 142mhz compared to a bandwith limit of 150.

Thanks a lot, that make perfectly sense.. And i didn't think about changing the green, so i have ringing if i have a HTOT less than 2400. Now i actually think ill be able to run 72hz with 1.78.1 material.. with my Radiance XS+ 
Ill try this out later tonight.. so again thanks a lot for bringing it to my attention.

Well i think ill build a hushbox.. Also i don't like big metal/ hard surface in my room. So ill play a bit with a hushbox and see how it effects my acoustic to.
But for now i'm rebuilding other parts of my house, and soon all my HT room will be down and get new construction and roof. So i don't think i'm ready before next year.
Just checked last night, i used my CRT almost 400 hours now.. Its almost the life time of a lamp in my JVC..

This weekend will be the last one with my projectors, and lately i have been looking movies on both my X7 and my 9500LC..
Right now looking Black Swan.. On CRT, and the other night watching it on my JVC..
Its just amassing black level on my 9500LC, and lousy on my JVC.
Other thing is how well my Lumagen handels framerate conversion from 50 to 60 hz.
I hope to be up running sometime early next year, where ill post some pics when i get it up hanging, and calibrated 100%

Question to some of you more experienced CRT guys.
Is it possible to make a blend with 2 lumagen mini or XS..?
Like oppo93- 2x hdmi out. into each lumagen and then crop the signal to each projector and split the horizontal resolution.?

Not if you want to do soft edge blending. And hard edge blending is even more difficult than soft edge blending.
Although you will need the CMS in either of the two mentioned VP's for both blend approaches. So for soft blend you would need either to got he PC route or a separate VP like the Tv-One or DiVentix units. There are others as well.

Thanks Athanasion...
Have no idea how its working.. Is soft blend some kind of fading out on the borders thats overlapping.?

Hello
The left "half" and right "half" are each about sixty percent of the screen width; they fade into each other by contrast modulation, which is controllable in the processor(s).
