Yeah try it, just make the refresh rate 48Hz. I think that is how I had it as well on the HDQ, I think @60 I was able to do it via RGBHV, but I had a MUX-HD after the BD player. I actually tried 1080p@72 via RGBHV and it worked fine. Its the DVI that is maxed at 165mhz. I think

So the MUX strips the HDCP prior to reaching the scaler, thus you can output 1080P/72 from scaler via analog and avoid the bandwith limitations of DVI.

[Nashou66]

Yeah. I am pretty sure it does 1080p@72. I'll have to check. I think its in the manual somewhere.

Image will not be converged since the timings have changed.

Athanasios

[jbmeyer13]

Yeah, but the image shouldn't be too narrow. I tried reloading the CORIO program but keep getting the same error:

Component tabctl32.ocx not correctly registered: file is missing or invalid

[Nashou66]

Are you running XP? not sure if it runs on vista or 7

[jbmeyer13]

Windows 7. Any other resolution editors out there?

[dvh99]

try using negative sync on both hor and vertical.

[jbmeyer13]

With Lumagen you have to enter the values with a remote; can't enter negative values for timings

[jbmeyer13]

Dennis,

I stand corrected, you can adjust polarity on the sync. It's buried in the Misc section of menu. Do you suggest I keep factory settings and just reverse polarity or do you have specific numbers in mind for H/V Sync and H/V Frn? I really sucks that I can't see the back porch timings on screen or the us specs...trial and error with a blind fold is not fun

It doesnt matter for +/- on a marquee. I just leave it at ++.

I hooked up a Blu Ray today on my Shop marquee, and was re-aquatinting myself with the HDQ. I forgot how to use the menu,
and it still is confusing. I ended up with some strange numbers for 1080p@48 I had to use the size in the lumagen to get the proper aspect ratio cause I maxed out the marquee's size to 100. it ended up being like 2300 something for actual horizontal res.
I had it set to scale tho. if you shut scaling off and do pass through it gets larger on my marquee Horizontal wise and I can go back to 1920 but then it pushes my vertical to low and I loose the menu of the lumie. Have a huge headache now, might get back to it
later but at 48hz I have no ringing. I did not try 60. But for the super bowl you'll want 60. can you change your sat/cable to to output 720p? if so use that. or use 1080i@90. I think NBC is 1080i native. adding a higher refresh rate reduces scan lines.

But for your BD player use 1080p@48 it works well and i never notice flicker.

Athan-

The default is too scale the image, thus I never turned off that function. I don't care whether its 60 or 48 for 1920 x 1080, just want no ringing. When you get home post or email me the exact settings at 48hz for all parameters (0-8 on menu). While each PJ is different I'll bet we end up being pretty close.

I think the real missing piece is going to adjusting the sizing via the Marquee and HDQ controls; I think that is what's throwing me off. When I altered the timing inthe ballpark of what you and Dennis suggested the image shrank. Properly Re-sizing/positioning and re-converging the image should get me where I want. That's the trick, making sure the re-size/positioning doesn't cause problems on raster with geometery, focus and damage to tube face.

Thanks for all the help thus far

[Nashou66]

Sorry I didn't get a chance, had to leave to go to work, I got a "call".

All's good.

You'll have to just mess around in there. there are a few areas that will get you where you want. Just finding the right combo
is the trick. From our call last remember the OUTSEL menu? changing the settings in there for the output will alter
the settings.

It may be frustrating at first, but when your done and are finally able to get to the greyscale/Gamma adjustments
you'll be glad you got the HDQ.

The hardest thing for me was the Independent output set up for Mem A/B/C/D. But it works well for when you have a multiple output
player like Blu Ray where you'll have 1080p@24 and 480i.

Back to work

From what I can tell the dop to 48 hz helps to reduce the ringing but not totally eliminate it. I have tried all sorts of combinations of HTOT, HRES and HYSN and none of those changes alter the ringing in anyway. All the HTOT, HRES and HSYN do is move the image left or right and screw up the geometery. When I use the overscan pattern I can get to the point where the overscan is equal on both sides but the geometery is screwed up because the center line is shifted either left or right of the where it should be. This is like throwing darts at a board blind...

Regarding the OUTSEL that needs to be set to "other" because the rest of the resolutions are not 1080P; i.e. 576/480, 720, 1080i, etc.

[Nashou66]

[jbmeyer13]

The size function does not effect the position of the image laterally; i.e. move the center. The phase function centers the image in the raster but does not effect the geometery. My image was dead center in the raster with near perfect geometery prior to this f'n Lumagen so it's not as if I screwed up the set up. I'm not shifting image to the right and then dealing with that fiasco of chassis alignment.

Dropping to 48hz and adjusting the timings screwed up the geometery. There are too many variables here between the timing, scan rate and geometery. Perhaps with the right timing the geometery will be correct but if I can't find that timing its meaningless...

For the moment this all means jack sh!t because now the Lumagen suddenly tells me that there is no source for the input; screen went static and then black. Add to this that the Lumagen customer support did not return my email today and you can imagine my mood at the moment...If I knew this was going to be such a hassle I never would have purchased it.

[jbmeyer13]

The part that has me baffled is that the timings had no effect on ringing, only the scan rate dropping from 60 - 48 hz made a difference with respect to minimizing the ringing. The HTOT, HYSN and HFRN move the image around laterally and have some effect on the size of the image but it turns out that you CAN'T correct geometery issues with porch settings. I was under the impression that perfect timing would correct the out of proportion areas of the image but in reality it sounds like it serves as a starting point rather than an ending point.

That means I was probably really close to having it correct, but all for not as the Lumagen has gone all out bat Sh!t...telling me there is no source, then displaying an image with heavy static. I'll press one button on the menu and it will do something completely different. I t was literally switching between resolutions without me prompting it. I brought up the test patterns and it wouldn't even keep them up, instead alternating between static and the BD player's image. Talk about a ghost in the machine...

[jbmeyer13]

When the HDQ went wacko it somehow caused my BD player to stop outputting 1080p/24 and that's what was causing all the static and other crap. Once I straightened that out its back to business.

I built my own poor mans timing calculator in excel since the us are all percentages of the setting (for horizontal it's .005777%) and these are my current settings at 48 hz:

Active 1920 11.092 us Active 1080 16.072 us
Hsync 88 0.508 us Vsync 8 0.119 us
Hfrn 54 0.312 us Vfrn 7 0.104 us
Back 306 1.768 us Back 26 0.387 us
Total 2368 13.680 us Total 1134 16.876 us

There is no noticeable ringing. My H phase is 50 and my V phase is 52 in the Marquee. In the Marquee my H size had been 52 previosuly and is now at 68 while the vertical size remains at 14. The H & V Marquee settings values are not really important since they can be different for each PJ but the fact that my phase is nearly dead on to what I had previously (50/50) leads me to believe that things are going in the right direction.

I think (hope ) that once I tweak the geometery I'll be in business. At least for 1080p...
