Let me look around

I have always started my calibrations with making the black and white clipping perfect, so it displays the source format, no more no less. And with no adjustment to contrast and brightness in the player VP and display if possible.
Just selecting the right level, now the moome behaves a bit wierd, it looks perfect to me with 16-235 source and select 0-255
And feeding it 0-255 it needs to be set to 16-235 or it will clip a lot of the sourse material.

Im still aware of what source use what level, and not to mix it.. But im not sure that the moome is not labeled wrong.
Why do it clip white if feeding it 0-255 and setting it to B 0-255, and close to perfect if selecting A 16-235
And feeding it 16-235, and selecting A 16-235 it will display much whiter than white, and clip perfect if selecting it to B 0-255
And the moome still dont limit displaying whiter than white, if the source is adjusted, so id dont clip like im used to with digital displays and VP.
It looks like it just do a level match, and not cutting the source.

Correct?
Nashou |
No its just a test.. its to tell you that the 0-255 --> 0-255 dont match. I always run my source 16-235. But i select the B 0-255 in the moome making a perfect clipping point. And a better black.

I still know, and i think i have been writing that 10 times now, i run all my sources 16-235, and its also written on the pictures i made.
The question is still how the moome card handels those levels. Its all about the moome card..

Mine is white yes, the 3D seems to be somewhat useless, ive never been able to make it work.
Im getting a new screen in a few days, a bigger one, so i will need to move the projector back abit and set it up again. Since ive put in this new quad it shows up the issues with my MOOME box more so than before, but at present its the only way i can use my bluray player.
Ive got gamma pot and contrast pot set all the way down, yet im still getting a black that is dark grey in the very dark scenes, when i use the PC with RGB i dont have that issue at all. The colour and image quality is pretty near the same when youre watching a movie, unless you pause it and compare.
It seems as though the MOOME is adding brightness to the image for some reason, but only at the extreme bottom end, as in its washing out the blacks, and there is no shaddow detail there either.
If i look at a greyscale stepped pattern, all bars are looking pretty grey, with the exception of ones that fall off the edge of the green wear pattern due to previous owner having the set too far back.

I was playing with those selections in my Internal moome, basically the same . But the Black boost kills Black and the 0-255 causes some issues with my TV-ones Edge Blend guides showing up on my screen, but that might be a tv-one issue i think i noticed it before but its not visible from the screen. The best so far for my set up is button A on the remote or the 16-235.
The Contras Adjustment you should not touch. so now what you have to do is put up a full white field and measure the voltage out of the green channel from the moome to .70 volts with gamma turned off, hit the 0 button to shut it off for sure while adjusting it. You may have adjusted the contrast so high your washing out blacks.

Black / gray.? That i found beeing a marquee calibration.
If you someday get the time, try use the B 0-255, and calibrate the brightness and G2 to it, and see how the dynamic range looks to you.
I still belive the A and B are labeled wrong in the moome manual, and the A setting you use is actualy the 0-255
Now it only acts that way with white clipping, in black it seems to be the other way around,, that the markings on the moome is right, but that is easy fixed using the brightness and G2 adjustments in the Marquee, where the white level cant be adjusted using the marquee settings.
The way it looks to me is when you can display whiter than white, you are not using the full white potential of the projector, and therefor limiting its dynamic range.
Hope someone can tell me how it realy works.
