i have the pn43d450 and it's very nice looking, but i'm having trouble with the calibration. i've got some test patterns as mp4 files.
when i run them via usb plugged into my ps3, no matter what brightness or contrast level i select (both extremes), i can't see all the bars, so useless for calibration.
when i run them via usb plugged into the tv, i get the exact opposite. no matter what brightness or contrast level i select, i can always see ALL the bars. ie, on black clipping with brightness down to 0 and cell light very low, i can still see all 20 bars of grey.
how do i calibrate? all the gimmicky settings are turned off, but it's like there is a permanent dynamic contrast switched to on!!
