Extron electronic Multi-Graphic Processor MGP 464 Manual De Usuario

 — Click this button to perform an automatic image adjustment to the selected 

window.  The MGP measures where the active area starts and stops, and 

adjusts input sampling accordingly, so that the image fills the window.  

 

When you click Auto, the processor measures the sync frequencies of the 

incoming video source and sets the active image area and sampling frequency.  

If an unknown input is connected to the MGP, the processor measures and 

estimates the resolution of the incoming video.  If the estimate proves not to 

be accurate, the Auto Image function makes measurements to more accurately 

set up the input sampling.

 — The Mute button closes or opens the selected window.  When the selected 

window is muted, this button is highlighted.  To unmute the selected window, 

click Mute again.  The highlighting is removed from the button.  

 — The Freeze button freezes the current image in the currently selected 

window.  When the image in the selected window is frozen, this button 

is highlighted.  To unfreeze the selected window, click Freeze again.  The 

highlighting is removed from the button. 

 

If you switch inputs while a window is frozen, the freeze mode is cancelled 

and the new input’s image appears in the window.

In the following sections, you can click a button to specify an input for the currently 

selected window.  When an input is selected, its button is highlighted on the screen.

 Click one of these buttons to choose one of the 

fully configurable inputs (1 through 4) for the selected window.  On the 

MGP 464 DI, these buttons also select among the four DVI inputs.  

  Click one of these buttons to 

choose one of the virtual inputs (5 through 19) for the 

selected window.  These inputs can pass only YUVi 

component video, S-video, or composite video signals, 

and cannot be configured from the front panel.

 

The virtual inputs are configurable in sets of three, arranged in columns on 

the screen.  When you click a button for an input that is configured as YUVi, 

all three buttons in the group change to blue.  When you click a button for 

an S-video input, the top two buttons become blue (shown in the example at 

right).  When you click a composite video input button, only the button you 

clicked turns blue.
