All,
I have been trying to use Avia to perform the video calibration on a pair of Pioneer 64" HDTVs (one mine, one a friends).
The first test pattern, the needle pulse thingy, gets us eveytime. What are we looking for on rear projection TV of this size?
On a scale of -30 to +30, we have to go down to about -15/-18 to get the verticle lines straight. But, then the bottom portion doesn't look very white and the brightness setting is just too low when we finished the cal at this level and go to regular viewing. (Though we can get the black level just right even in this mode.)
We look at the steps in the upper half, but they do not appear to bloom even at max contrast. But, the vertical lines are definitely bent at setting of +10 and above.
The rest of the pattern tests we have no problem with.
Are we missing something here? Do we go for white and forget the lines? For rear projection HDTVs do we need to look at something else?
We can both invoke a "dark enhanced" mode on our DVD players.
Thanks,
KenRen
