Vertical Resolution - Programmable
This command allows the output active vertical resolution to be set from 480p to 1080p,
in scanline increments. See the Selecting the Output Resolution section for more
information. This command maintains the current display type, aspect ratio, and vertical
refresh rate. Out of range values are ignored. The command format is:
MENU , 3 , value, OK
or
MENU → OUT → RES → VRES →
value, OK
Vertical Refresh Rate
Set the output vertical refresh rate in the range of 48, to 75, Hertz (entered in hundredths
as
4 , 8 , 0 , 0 to 7 , 5 , 0 , 0 ). See the Selecting the Output Resolution section for more
information. This command maintains the current display type, aspect ratio and vertical
active resolution. The display must support the vertical resolution and vertical rate
specified. Out-of-range values are ignored. The command format is:
MENU , 4 , value, OK
or
MENU → OUT → RES → VRATE → value, OK
Horizontal Refresh Rate
Note:
Do not use this command unless the display requires a rate different than
the interpolated rate and the correct horizontal refresh rate is known.
Set the horizontal refresh rate in Hertz. The vertical total scanline count is adjusted to
achieve the specified horizontal frequency, if possible. The active vertical resolution is
not changed. Out-of-range values are ignored. The command format is:
MENU , 5 , value, OK
or
MENU → OUT → RES → HRATE →
value,
OK
Horizontal Sync Pulse Width
Some displays require a narrower horizontal sync pulse than standard SMPTE timing.
This command allows the HSync pulse width to be controlled. The command format is:
MENU

Output Size
Note:
Generally, this command should not be used. Instead use the display’s size controls.
Change the percentage of the scanlines that contain active video, and the percentage of
each scanline that contains active video. Only the active times are changed. The vertical
total-scanline-count and horizontal total-pixel-count are not changed. An example use for
this command is to match fixed display timing requirements. This command can also be
used to match the pass-through input timing.
