Alright, I had it going before, but had to wipe everthing out on my computer and now it I can't remember how to set it up again. It's easy to create, but I'm missing 4 inches on both sides of picture when doing 1920x816@72Hz, so to at least get going I had to lower the width to 1820x816@72Hz to get the full width. Now that's with automatic creation of porches so never messed with that at all. The bottom line is that I forgot how to set up custom porches.. It's really eating me knowing that I'm missing those last 100 lines horizontal...

Help me you CRT doctors!

Was the Marquee re-set too? This sounds like a long/short retrace issue on the Marquee, try resetting the retrace to short, see if that helps.

No, it wasn't reset so it's on short as before. Why didn't I write this down.

I can get full width now, but then I need to move the pj backwards about 100 cm. So far so good, but the real actuall image with 1920x816@72 Hz is now smaller than my screen is! (At present distance because it's haning in chains now and can't be moved)

It's only filling up about 2/3 of the screen and only 2/3 of the raster also. I'm maxing out width to 100 and still there is 1/3 left of usable raster. Raster hight is dead on at zero and fits my screen exactly. Makes me wonder if I need some modification to it to alow greater width.. But that dosen't explaine how I got full width before, and only 95 at that. I'm certain that I was at 3 on hight while at 0 now. I'm sure I used all of the raster back then too. Weird..

We need to know what your total porch setting is for 1920.
Also give the rest of the numbers. You might have too much in
timings in the blanking portion of the image.

Ok, thanks for helping me out.

This is the actual numbers being projected when going to diffrent modes for this sollution. It dosen't matter if I go for one or the other, the image is still 2/3s of its potential. The numers may change a little but the image stay the same. Will post some pictures as we go along if that helps.


"Tidsintällningslås" changes a little when flipping thru the different alternativs (the picture shows automatic mode) but remains the same width anway no matter what. 2/3.

Update: I can't move the pj backwards because the hight limit is at zero. If I go backwards, to fill the the screen sideways, I then nolonger can shrink the image anymore as it's already at zero.. That proves I made it right the first time with this distance I think.

Width: 100

Hight: 0

When showing the Overscan pattern from DVE if you have it, does it show the entire image or is it cutting off some?

Switch once more between short and long retrace, to see how much gets cut of going to long.

Don't have the DVE so can't tell you more than that. Switched from short to long and it almost solved it! missing like 3 inches now both sides to fill the screen.

The raster is getting closer to the edges, but still like 4/5 to make it absolute use of all the usable raster. It's usdable though. If I only could make it just a little bit bigger I wouldn't have to drill new holes in the ceiling. But if I have to it's 5-6 inches behind where I'm at now. Thanks for basically solving this for me.. no one ever told me it could be LONG on retrace before. Looks like I'm drilling new holes again..

Thanks btw. Let me know if there is any more I can try.

First look at the actual Image. you'll need a pattern that you can see the overscan.

You might be cutting off some of the image.

Here is a 2.35 aspect Image of the overscan pattern

These will also help you set up geometry a little for 2.35.

I have some more if you want them.

That overscan shot shows only up til 10 % on width and only up til first visable line upwards. Took a screenshot showing it. Still looks cropped some how, yes?

Yes very cropped, now do it with short retrace.

Retrace short: It looks exactly the same. But the image is shrinking to like before (2/3) (showing the whole image as well). Though shifted more towards the right now by like 1/5 looking into the lenses.

Easly corrected by phase to be alike both sides.

Long retrace makes it missing 2 inches both sides, but cropped some how anyway as you said.

Makes me think I never got it right before either because I only moved the pj a litte backwards to fill the screen back than.

I was right, you need to keep it at short retrace, in long you loose a lot of the image. Over 20%.

You need to make custom timings in the NVidea panel. Lowering the total pixels from 2560 to say 2460 will make the image bigger.
First lower size in the marquee to about 90. then adjust the total timing. also lowering the Sync and Back or front porch , say 20 pixels at time will also help. . then you might need to use Phase to center the active image. Keep messing around with settings till the entire overscan image is visible . You might need to do the same for the hight of the image as well.

Ok, thanks again New Yorker. I will mess around with this as you said and try some different modes.

Until then.

Bye and thanks! Smile

I must be drunk because its looking good all off sudden. Must check with your resolution pictures to be sure first. It's all there all of a sudden, just did a little touch up on a tryout channel, and done. Looking good inside lenses also at full use of raster. But I'm sure it's gone tomorrow.

Update: It's filling the whole screen now, but that picture you showed me, is still only at 10 % width. Now we can be sure I was all wrong before also. But inside lenses it's showing all of the usable raster at the moment... very close to edges and wouldn't go any closer.

Hor: 98 Ver: 1

Update 2: Retrace Long. Making it Short makes the image narrow again.

Update 3: Get well, btw, and thanks again.

Hi again and thanks for all the help. It's working now. Both your images are showing correctly now and I'm using 1920x816@72 Hz. Will write this down for futhure references. Retrate is set to Long and total pixel was reduces to 2460 and then it seemed to work.

I cannot believe my eyes, but the ringing is GONE! I don't why but it's looking real good. But the image is slightly to the right and very close to the raster edge. But I'm gambling on it not ro be ruined after some hour of use. I will be forced to move the screen about 2-3 inches to the right in order to centralize the image and raster.

yep, one trick to avoid ringing it to move the image over out of the ringing "zone". the porch settings also helped you remove it probably.


Now write those settings down!!!
