Pass-Through mode
The source image is scaled by default, even if the input and output resolution match (e.g.
1080i in and 1080i out). The SCALE command allows scaling to be disabled if the input
and output resolutions match. Note that since the general case is to have a single output
resolution that matches the native resolution of the display, any source input resolution
that does not match the output resolution is still scaled.
MENU → IN → CONFIG → ADJ → SIZE → SCALE →
( NORM , PASS ) OK
Y/C Delay
Adjust the horizontal Chroma timing in relation to Luma. It is suggested that the Y/C-
delay calibration image from the Special Tests section of Advanced AVIA, be used to
calibrate the Y/C-delay. The C
B
and C
R
channels are adjusted separately.
MENU → IN → CONFIG → ADJ → YC-DLY →
[ … , † , ˆ , ‡ ] OK
Sharpness
This command is used to adjust the sharpness for all inputs It is generally best to leave
this at the factory default setting. The command format is:
MENU → IN → CONFIG → ADJ → SHARP →
[ … , † ] OK
Input Level
This command specifies if an analog input has a black pedestal, or whether DVI inputs
use video levels or PC levels. It is better to leave these at 0 IRE for analog, or PC level
for DVI-D, if unsure. The analog command format is:
MENU → IN → CONFIG → ADJ → LEVL →
( 7.5 IRE , 0 IRE ) OK
The DVI input command format is:
MENU → IN → CONFIG → ADJ → LEVL →
( VIDEO , PC ) OK
Input Name
Each input configuration memory can be named. Follow the on-screen directions. The
… and † arrows select which input to change and then which character to change. The ‡
and
ˆ
arrows change the selected character. The command format is:
MENU → IN → CONFIG → NAME
Select Deinterlacing Mode
The default deinterlacing mode, for both SD and HD material, is to automatically detect
film or video source material, and deinterlace accordingly. Since this can never be a
perfect detection, the Lumagen processor allows the user to force deinterlacing to assume
the source material is video. For SD material the choices are AUTO and VIDEO. For HD
there is an AUTO mode and two video modes.
The HD VIDPP mode uses a “per-pixel” motion adaptive deinterlacing algorithm (as
used for SD deinterlacing), and the VIDNC uses a scaling deinterlacing method. While
the VIDPP mode generally provides the best image, the Lumagen will not comb in
VIDNC mode, and so VIDNC is sometimes preferable.
