I have been wanting to do AAS with my lumagen and CRT projector. That is to have the CRT face only scan the active image(not the black bars on top and bottom with 2.35 matierial) so i can save on bandwith and use a higher scan rate. I have read on another thread to use the TOP L and Bottom R adjustments. I tried this and got t to remove the top balck bars but can't get it to remove the bottom. Is there something i am doing wrong?

Also the image moved to the top of my screen where i wanted to keep it in the middle where it is on my 16x9 screen.

Any other way to accomplish this?

You should be able achieve the modes you are asking for. You might have already done the following, in which case, please call our support line at 503-574-2211. We are on Pacific Time and are here from a 9 to 5:30. If you need help outside this timeframe it can be arranged. If you haven't done the following please try this out:

After you have everything set up for 16:9 mode, you need to set mulitple output mode, select the input memory you want to use for this mode, then select a different OUTSEL for that input memory.

Then set the output resolution and timing for the 2.35 mode, and set the output aspect to 2.35.

Select 2.35 input aspect ratio. Using the older remote this is done by pressing 16:9, and then up-arrow twice. The new Radiance remote has a 2.35 input aspect ratio button (has the same effect so it doesn't matter which remote you use).

Only then should you use TOPL and BOTR commands to get the right amount of cropping.

Make sure to save your changes.

Doing this filled the screen and zooms the image in and i lose the right side of the image. That is not what i want to accomplish. I want the black bars on the top and bottom not to be drawn on the phosphor of the tube but they will still be there. Unless i did something wrong?

i have a 1.78 acpect set up on input 2a and set to 1080p24sf and the output to 1080p48. so all i did was while on this select the memory B and then set the input to 1080p24sf and the out put to 1080p and scan to 48. under the aspect i set 2.35. then i croped by removing the black bars but the image then fills the 16x9 and i lose the right side of the image. I want to keep the 2.35 aspect and not have the black bars being sent to the projector.

Maybe i'm doing something wrong?

I am doing the same thing but a different approach, I run A g70 1,500hr's, for HDM I run 1920+1080@24p into A VP50pro And output A rez timing of 1920+800@48hz to stay in the bandwidth limit of the projector.After centering the raster on the tube face I set my RGB shift to mid point and center the image(tweak) on the tube face buy adjusting the VPpro's advanced format settings,After setting the 1080p rez in the VP (tweak) H-shift/H-size is(1920)H-front/H-back/ I don't touch the V-settings except obviesly the V-size(800)this way Im not wasting my bandwidth on black bars.

but there is still black ontop and bottom its just that its notbeing scaned by the projector correct? Si i think i need to set output to 800x1920 and keep the input as i have it. i'll give it ashot later.

I don't think you have the output aspect set to 2.35. It sounds like it is at 1.78 (16:9) still.

If you set the output aspect to 2.35 and select 16:9 input aspect you will get pillar boxes on the left and right. Then zooming in twice allows a 2.35 source to fill the screen, but not lose image at either top/bottom or sides (excepting any overscan you have dialed in ).

If this doesn't help, it might be best for you to call us on Monday (503-574-2211) and we can discuss it on the phone.

I went over everything and used both Jims and cinema mad's advice. I set in the timing menu the actual vres at 800 for 2.35 and then set the actual hres at 1920. then i went to the output mode and selected output mode 4 and then set aspect to 2.35. then croped the black bars out on top and bottom. but then i had to also use the size and position options to stretch the image wider and center left to right even after using the 2.35 aspect. then went into the test patterns and yep the gird was in the 2.35 aspect ratio!!! woo hoo took me many trial and errors before i figured it out and still not sure if i can reproduce it. I'm sure i left something out. but i finally got it.

What i difference it makes! the image at 1080p48 was great but now just using 800p48 it is awesome!!!!!!! the Image is just shaper and punchier. I also toned down the gamma slightly from my previous higher setting in the lower IRE's and my blacks are a bit darker with out the crush and now not being washed out a bit. Gess i have to add activities to my harmony 1000 remote now for 2.35 and 1.78. I also added another memory to my marquee.

Thanks Jim and Cinema Mad.

PS Jim Really rooting for the blending option from lumagen. Love your algorithyms you use compared to the rest of the pro blend units.

I am glad to hear that you set it up the way you wanted,there is still obviously going to always be black bar's but you are not wasting you bandwidth on them there for staying under the projectors limits and producing A sharper punchier picture instead of A soft picture when doing 1920+1080@48.
