Signal Format screen

The Signal Format screen shows the video format (such as RGBHV, component video, or S-video) assigned to each input and provides the ability to change the video format assigned to each input.

It is critical that the signal format selected is correct. If the wrong input circuitry is selected for the input signal, the scaler will not function properly and will display either a distorted image or no image at all.

To enable seamless switching, input 4 must be configured as passive (unscaled) on the Signal Format screen. However, once it is configured as passive and if input 4 is selected, the scaler cannot place the on-screen displays on the output video stream.

No video adjustments are available for the input 4 video signal when it is configured as passive (unscaled) but audio and other input variables are still adjustable. It is helpful, therefore, to configure all of the input 4 options before you configure input 4 as passive. If, later, you need to change any of the input 4 settings, the easiest way is to temporarily set input 4 to one of the scaled output settings.

The signal format is the only input variable that you can change when that input is not selected. By selecting an input other than input 4 before pushing the Menu button, you can see the on-screen display to reconfigure input 4 from passive (all on-screen displays blanked for input 4) to one of the scaled outputs. That will allow you to see the on-screen menu and change other settings. For seamless switching, remember to set input 4 back to passive.

Change the input video format as follows:

1.

Press the Menu button. The on-screen Main Menu display appears on the

 

connected monitors, overlaid on top of the output image.

2.

Use the Menu

and

buttons to highlight the Input menu option on the

 

Main menu and press the Enter button. The Input screen appears on the

 

connected monitors.

 

3.

Use the Menu

and

buttons to highlight the desired input and press the

 

Enter button. The selected input’s format selection options appear on the

 

connected monitors (inputs 1 and 2 can be set to S-video and composite video

 

only, only input 4 can be set to passive (unscaled)).

If seamless switching is on and you select input 4, the format selection options do not appear. Rather, the connected monitor displays, “Seamless is ON — RGB passive only”.

4.Use the Menu and buttons to highlight the desired video format, then press the Enter (and save) button.

Aspect Ratio screen

The Aspect Ratio screen displays the relative image width and height that are currently selected for the selected input and provides the ability to change the aspect ratio. For best results, the input aspect ratio should match the output device aspect ratio (see Resolution screen in this chapter). The selected aspect ratio is indicated by an arrow (➔). The following aspect ratio selections are available:
