Is the retrace still set on short? Remember with each new resolution it is a new memory.

[thewolfman]

Yeah, retrace is still on short.

I have created channel 816p@72Hz though, and got monitor and pj working together now, but as before, the pj won’t show the whole width, except monitor, and still missing 4 inches on each side. Probably needs some fine tuning with porches and stuff I don’t know much about. I only choose 72Hz and 1980x816 on this, that’s all I did.

Every time I need to create a resolution, or fiddle with timings if I choose to make a resolution manually, I need to change the monitors input on the graphics card. Otherwise it won’t work. And while altering and creating resolutions the monitor becomes useless.

It’s not blanking, btw.

Thanks for helping me out though.

[CasetheCorvetteman]

Its not covered by the blanking is it?

72Hz the image will probably be about that amount wider than 60Hz.

[thewolfman]

Ok, so that's how you interpret Hz... I didn't know that.

Some movies can’t be shown the way they should either, they image becomes very small and only takes up about 60 % of the raster in the middle. I haven’t looked at so many movies yet, but seem to be working fine, besides the cutting of the edges, for the most part. No blanking issues, btw.

Na.. better go to sleep and get back to it tomorrow.

[CasetheCorvetteman]

The reason they come up small is cause it is displaying SD content inside a HD space at a dot for dot ratio instead of interpolating it to fill the screen, adjust the video player settings to correct that.

If it wasnt blanking, id expect it would be folding at the edges, and if it is, your porches are too short.

[thewolfman]

There is no folding, except on the lower left corner of blue. It’s there no matter what resolution I choose so probably not the folding you are talking about. I have tried some different numbers randomly, but that only caused the entire image to shift left and right, just like Phase in the pj does. Don’t seem to be getting anywhere with 72Hz. I took a screenshot of the automatic values for 72Hz and if anyone has suggestions on what to try next I am happy to try that.

Powerstrip has all of a sudden started to work also and made a resolution from there to, but again, it behaves just like Phase when trying to shrink the image. Left and right, that’s all I can do with it.

Btw, the movies that go small have always been blu rays and not SD, but changing it back to 1920x1080@60Hz makes them look right.

You need to make the active horizontal 816. then add more Total to vertical from 2200 to say 2400 then add 200 to front porch or in your screen shot Framstangning make it 290. try that. your program is not showing one of the porches. Front, back actual and syn should equal total.

Ok, I will try those numbers and see what happens next. Thanks.

[Phoenixed]

Nash.

Would your conversation with Jeremy apply here? In it you were discussing the exact lumagen settings.

[thewolfman]

I have tried many different numbers now and it's impossible to get it right. Did like you said with adding up the numbers so total is the same, but it did not work anyway. I will keep going at it some more but with Powerstrip instead. There is a blue print from the author of this thread and will give them numbers a go later.

I sure could use a beer right about now for extra strength.

[CasetheCorvetteman]

Pull it down and put up an NEC, that will fix it.

[thewolfman]

I tried my best, and thought for quite a while I made it, because I finally got the width right. I had to scootch the pj backwards 2 inches and redo everything. But then I realized only the Baraka movie looked good, and not only good, but also shifted the ringing out completely, and man was that beautiful. But when watching Prometheus and some others, the blacks was all wrong and I never got it right. Basically every movie demanded its own geometry and I got fed up with it for now. I had to lower the brightness from 44 to 28, and a little on contrast, but still looked very bright anyway, and decided to go back to 60Hz and be done with it.


Update:I forgot about the players own geometry, and so all "small movies" look good now, when changing to 2,35.1, and just like you said it would. Thanks. If I only could sort out the black levels so it looks like 60Hz, I'm home.

[Nashou66]

Not bad!!! Keep tweaking things thats the fun of CRT !

Excellent screens, Peace, they remind me of how nice my XG looks when watching video on it. The rest of your room is awesome as well, keep up the good work!

[thewolfman]

I finally got 72Hz working now and have the whole image showing. I even got contrast and brightness to be the same as 60Hz. I had to lower the contrast from 64 to 55 and brightness from 44 to 22. Took a lot off before and after pictures, to absolutely sure I wasn’t getting less contrast and got it right eventually. The difference is hardly noticeable, but it’s there, everything white looks slightly cleaner and has a little more pop to it.

Even so, I never got 1920x816@72Hz to work, because width was always overshooting the edges and was unsolvable for me. But it didn’t matter, because I ended up with 1920x1080@72Hz instead, and got the whole image that way. Nothing else worked.

Thanks everybody!

Wolfman this thread may help ya.

I can't do that, because Powerstrip won't allow me. Apparently it only let’s me use part of it, but create a custom resolution can be done, but altering the numbers on the page you are referring to can’t be done, because they snap back to 60Hz when trying to apply them. Also I need to uncheck Real Time Adjustment for the numbers to be changed at all. If anyone can change them without doing so I would like to know.

I sent Powerstrip an e-mail, asking them if the trial version really can be used for a period of time, but they didn’t answer me back. I don’t have the cash at the moment to just buy and try. I will later though.

[Phoenixed]

Powerstrip and nvidia are incompatible. I updated my post to after noticing the photos weren't correct.

[thewolfman]

It's good reading within that thread and for sure there is more to be learned. Get back on it tomorrow and see what happens.

Daddy’s not home.

Hello!
Yeah! 72Hz is nice!
Try RGB size on the remote for the last inches.
