I'd just do the best I could using the setup disc, and see if that is going to be satisfactory. Any other changes probably needs a professional calibration and/or a different screen gain.
Great you're familiar with the spears and munsil cal disc!?
This post will be very long and I apologize, but in a desperate attempt to solve my issue, here goes!
Please note that this is while using the s&m cal disc. Images of what I'm talking about can be found at http://spearsandmunsil.com/articles/...epatterns.html
Here is my problem with what you just recommended; it may sound crazy but I fully believe this whole issue lies in my bluray player, and here's why. It seems like my bluray player (elite 23fd)is completely overriding my projectors display settings. What I mean by this is that, I can change brightness and contrast on the infocus but it does very little. *I mean I can move them both up and down and you can see a distortion of the image, but it simply will not allow the image on the screen to do what it needs to do to look proper. *
My bluray player has several settings on it to choose from, being plasma, LCD, projector, pioneer projector, pioneer plasma, memory 1,2&3, and professional. *I HAVE to chose on of these. *Memory 1,2&3 are all adjustable, the rest are all presets. *
Now let's say I choose projector...By doing this, it defaults to the preset settings programmed picture settings in the bluray players video proccessor. *With the bluray set to "projector" and the infocus sp8602 set to default settings (all at 50...right on the middle) and I open up the low pluge, I see no left bars at all, only the right 2 and the checkerboard pattern. *It even has the static while looking up close in the gray squares with the other squares in the checkerboard being completely black. *BUT, no matter how high I turn brightness up, I cannot see all four black bars, just the two right ones.
So, on to contrast...with these same settings (bluray set to "projector", infocus set to factory default) there is major clipping. *Only 3 white boxes show on the bottom and the rest are blending with the white background. *Now when I try to turn up contrast via the infocus, just 1 notch (from 50 to 51) it completely clips the 3 boxes that you could see and is completely white. *So I try to lower the contrast via the infocus, and no matter how low I go, the image simply gets dimmer, and this 3 white boxes are still the only thing that can be seen on the bottom, even with contrast set all the way down to zero.(I can't remember the box numbers but they are the far left ones)
On to clipping. *With the same settings (bluray set to "projector" and infocus set to factory default settings) every single rectangle (W,b,r,g) are completly clipped and again, by using the infocus, turning down contrast does nothing at all but dim the image. *
It does this with all settings on the bluray player except memory 1,2&3.
Now with all of that said, I can leave the infocus at the factory default settings (50 on everything...right in the middle) and change the bluray to memory 1. *Memory 1 is not a preset and can be manually adjusted. *
Onto low pluge once again...by using the memory 1 and manually setting the black level through the bluray player, all 4 bars show up when I turn the black level up, but no checkerboard, so I adjusted it to where the second from the right bar dissapears and turn it one notch higher to where it's barely visible...the two left bars are also invisible at this point.
On to contrast. *By again using the bluray player and turning down the white level this time, all white boxes except the farthest to the right now show up. *The last one on the right clips. *This is correct I assume. and with these settings, even the black bars at the top of the contrast image that show brightness, I can see 18 and above...below 18 are blended into the background, which I assume this is also correct.
Onto*clipping...the*white*and*green*rectangles*are*working*j ust*fine...no clipping in those at all. *The blue and red rectangles however show just a bar down the middle. *So they aren't completely clipped but mostly clipped. *I can turn contrast down to unclip them, but when I do this and go to the contrast screen, every single white bar on the bottom is visible now, and I thought all except the farthest right were supposed to be visible.
Back to the clipping image. *If I leave contrast alone and turn down gamma just 2 notches, nothing is clipped anymore, and by doing this doesn't change anything on the other screens as far as I can tell. *
So it seems that my bluray player is overriding my projector somehow. **
I'm going to go look at the cropping image to check gamma right now. Hopefully it's on par and my gamma adjusent didn't effect anything.
