|
|
this pj was well setup before i got it. after an accidental initialization, the rasters look perfectly centered, but there appears to be room to expand the raster a bit.
i'm out of room to back the pj up, so i want to make sure i have the raster as large as possible.
i have the horizontal size at 100 already.
is it true that the internal test patterns are wider than source signals (mine will all come through a lumagen hdp at 960/1080p) so as long as the internal patterns don't spill over the phosphor area, the source width wont go over either. am i right?
so other than the size control, is there a way to increase the raster?
thanks!

Hello
The patterns are wider than sources by several inches. In the Pic menu you want Long Retrace. Backing the slugs out of the width coils might buy you another inch or two.

Surely it depends on the source porch pixels?

Also, there is a jumper on the HDM, under the daughterboard, that will
allow a small increase in width - however, I cannot recall the # or whether
it should be on or off (getting on am i...) but I bet Tim or Scott know offhand
the exact details...

What is your source? If it is blue ray and you don't have an htpc or processor try this, try long retrace and pause pic, switch to short retrace, look at pic. I think you will find that you are missing about 25% of the image on long retrace. Porch settings on blu ray seem to be hooped. For blue ray I went to a lot, I mean a lot, of work to set up the magnetics and keep jailbars on left hand side to a min. I run 1080P in my little 8500 and have scan lines thru the center of the screen for about 5' on bright scenes.
