Some DVI-D/HDMI displays can achieve a “pixel-perfect” image, but require specific
pixel timings for all parameters, not just active pixel counts. Note: Skip this step for
analog output. Lumagen video processors can accommodate these displays using the
TIMING command. For more information on using this command see the Exact Output
Timing section (page 16). The command is:
MENU → OUT → RES → TIMIING
•
If pixel perfect mode cannot be achieved, adjust overscan. Skip this step for analog
output. If pixel-perfect mode has been achieved, skip this step, since these operations
may disable pixel-perfect mode.
Adjust size and position to have approximately 0% to 1% overscan, as shown using the
Lumagen overscan test pattern. Note that overscan will be adjusted to approximately
2% while adjusting the input configuration.
Select the overscan test pattern with MENU → MISC → TPAT → OK . Then use the right
arrow to step to the overscan pattern. If the display has output size and position, use
them. Otherwise use the Lumagen commands. Note that the Lumagen’s commands
cannot be entered while the Lumagen overscan pattern is displayed, so this method may
require some iteration. The commands are:
Output size: MENU →
OUT
→
RES
→
SIZE
→
[… , † , ˆ , ‡] OK
Output position: MENU →
OUT
→
RES
→
POS
→
[… , † , ˆ , ‡] OK
•
Set the output aspect ratio to match the screen. Skip this step if the screen aspect ratio is
16:9 (the default). Press “ MENU 0 6 value OK ” where “value” is the screen aspect ratio
in hundredths (4:3 is MENU 0 6 1 3 3 OK )
•
Set the output level. For DVI-D/HDMI displays it is important to match the display’s
requirement for this parameter. If unsure, selecting DVI-D as VIDEO output level is
safer. Most analog displays work well with either pedestal setting. The commands are:
For analog: MENU → OUT → LEVL → PDSTL →
( 0 IRE , 7.5 IRE ) OK
For DVI-D: MENU → OUT → LEVL → DVILVL →
( VIDEO , PC ) OK
•
Select the input type for the component/RGB inputs 3 and 4. Skip this step if input 3
and 4 are component and use the correct color-space. Select desired input, then press
MENU → IN → TYPE →
( SDYPBPR , HDYPBPR , RGBHV , RGBS , RGsB ), OK
•
Select the input type for the standard definition analog inputs 5 to 8. Skip this step if the
default modes for these inputs are correct. Note inputs 5 and 5 can only support SVideo
or composite (VID). Select desired input, then press
MENU → IN → TYPE →
(
VID, SVID
,
YPBPR
),
OK
•
Set the video input levels. If unsure, selecting 0 IRE for analog, and PC input levels for
DVI-D, is safer. The commands are:
For analog inputs: MENU → IN → CONFIG → ADJ → LEVL →
( 0 IRE , 7.5 IRE ) OK
For DVI-D inputs: MENU → IN → CONFIG → ADJ → LEVL →
( VIDEO , PC ) OK
Output Calibration:
•
The interface between the Lumagen and display should be calibrated first. This is best
accomplished using the internal Lumagen test patterns to assure that any variance in a
