24 • Digital Video Processor: C2N-DVP4DI
DEFINITION
Actual number of horizontal pixels displayed (Minimum 800,
maximum 2000)
Actual number of vertical pixels displayed (Minimum 600, maximum
1200)
Refresh rate depends on resolution; the clock speed settings
determine this parameter. Example: If parameter 1 is 1600, the
maximum rate is 60 Hz
Choose negative or positive
Choose negative or positive
Total number of horizontal pixels. Cannot be less than the sum of:
parameter 1, plus clock duration, plus back-porch pulse sync width.
Pulse width sync
Horizontal Back porch
Total vertical lines. Cannot be less than the sum of parameter 2,
plus front and back-porch
Lines of vertical sync duration
Vertical Back-porch
You cannot enter an invalid resolution (less than the minimum).
Example, entering a horizontal resolution of 768:
DVP4DI>output 1 768
Invalid Resolution
The C2N-DVP4DI will accept all valid entries. When the C2N-DVP4DI encounters
a number not in the firmware, the following message is displayed:
Example, entering a horizontal resolution of 875:
DVP4DI>output 875
875 is not in the C2N-DVP4DI table of Standard
Horizontal Resolutions.
You can set a Custom Horizontal Resolution by
typing:
Output 1 875
NOTE: You must reboot for changes to take effect.
NOTE: In this example, the C2N-DVP4DI prompts you with the output number (1)
for horizontal resolution.
NOTE: The C2N-DVP4DI will output 800 x 600 in this example until all the other
parameters are set to make it function properly for the new output.
NOTE: Also ensure that you have created the correct page size in VT Pro-e before
creating a page for the new output.
NOTE: There are two additional standard output resolutions for the C2N-DVP4DI,
1152 x 864 (RGBHV) and 720P. The 720P is HDTV with a resolution of 1280 x 720
(progressive scan) but it outputs as RGBHV and not Y, P
setting, use the command: output 720P
