4. Operation

Setup Menu

Direct measurement of the signal

If the input signal’s timing is too different from the saved configuration, a good lock may not be possible. In this situation, the “Invalid Signal” message is displayed, and the video output will be black. You will also see “Invalid Signal” if the configuration file for an input has been deleted.

When Auto Acquire is OFF, dial in your timing parameters manually. Please note the following important points:

It is recommended that you leave the Auto Acquire mode ON. Then, if the timing changes on any input (whether or not you have a saved config file), you will always get an output image. On the other hand, if the mode is OFF and the input timing changes, the output will be black.

When the Auto Acquire mode is ON, the PDS automatically detects and acquires the input video type and resolution (in most cases), and limits menu selections to those applicable to the detected video type.

If you are an advanced user and you know the exact timing parameters for your input(s), you can turn the Auto Acquire mode OFF, and dial in your timing parameters manually.

Tip

If you have already saved configuration files for your inputs, it is recommended that you turn the Auto Acquire mode OFF. This provides the fastest transition times. When the mode is ON, transition times will be greater, due to the time required to analyze the input timing for each source.

The following functions are available:

Aspect Ratio — This function allow you to adjust the image to one of the following values: 1:1, 3:2, 4:3, 5:4, 16:9, Custom.

Ratio — If Custom is selected, the Ratio line appears:

~Adjustment range: 0.750 to 3.000. The default value depends on the last Aspect Ratio selected before Custom was chosen.

~Note that the PDS displays the input video aspect ratio according to the input format detected. For example:

Computer video at 1280x1024@60Hz defaults to 5:4 aspect ratio.

NTSC video defaults to 4:3, HDTV 1080i video defaults to 16:9.
