RGB Delay
The RGB delay feature applies a brief delay before displaying a new picture to a screen and allows the display device to adjust to the new sync timing. This feature provides
The blanking period can be set from 0 to 5 seconds in 0.5 second steps.
OSD label
Use the
• Line 1 displays the input number. • Line 2 displays the input type.
• Line 3 displays a text label that you can define (input 4 only).
The display time can be set from 0 to 5 seconds in 1 second steps (default is 2 secs).
Test pattern
Test patterns are useful when the DVS 304 is used to output differing resolutions. Choose a test pattern to properly adjust the image using built in crop, alternating pixels, and color bars.
Enhance mode
When the enhance mode is set to on, automatic gain control of the video input signal is enabled. If the input signal level is too weak, signal gain will be increased, and if the input signal level is excessive, signal gain will be decreased.
Using either the Adjust horizontal ([) or Adjust vertical ({) knob, select (< >) either On or Off as desired. The default is Off.
Refresh Lock
When Refresh Lock is applied the vertical output rate is locked to the incoming vertical refresh rate to prevent tearing and/or stutters associated with frame conversion. This mode should only be activated when excessive stuttering and/or tearing is being experienced with an input signal.
NThe output refresh rate must be set equal to or greater than the incoming video’s refresh rate or no video output will be displayed.
If the incoming video’s vertical rate differs significantly from the set output refresh rate, no video will be displayed.
Auto Memory
The DVS 304 stores 16 auto memories with input and picture control data for inputs 2 ad 4. The default settings enables these memories to automatically recall input and picture controls for signals that have been previously applied. By disabling auto memories, the DVS 304 will treat every newly applied input as a new input. Default is on.

| |
ON | ON | “New” signals /rates that have not been previously detected by the DVS 304 are initially | |
|
| using default parameters, then auto image is automatically applied and values stored. The next | |
|
| time the same signal is detected, the values stored in the auto memory location are applied. |

ON | OFF | “New” signals /rates that have not been previously detected by the DVS 304 are | |
| (Default) | default parameters. If manual input and/or picture settings are made to the input, an auto |
|
|
| memory location is created and recalled each successive time the input is detected. |
|
OFF | ON | Each change in input sync triggers an automatic auto image. When auto memory is disabled, | |
|
| each different signal is treated as a new signal and default picture controls and automatic auto | |
|
| image is applied. Any manual changes made to the image and picture controls are lost each time | |
|
| a new rate is detected. |
|
|
|
| |
OFF | OFF | Each change in input sync causes default values to be applied to the rate. Any manual changes | |
|
| made to the image and picture controls are lost each time a new rate is applied. |
