This chapter describes how to use the features of the Silicon Graphics MultiLink. The on-screen display provides access to the flat panel display controls.
The five buttons on top of the MultiLink, shown in Figure 2-1, interact with the on-screen display.
Figure 2-1 Buttons on Top of the MultiLink
You use the five buttons on top of the MultiLink to:
Start and stop the display of the on-screen display (the select button)
Choose a menu (right and left directional buttons)
Choose a menu item (up and down directional buttons)
Change the mode focus from selecting menu items to changing display settings (the select button)
Change settings (directional buttons)
Save settings and exit (the select button)
To display the on-screen display, press the select button.
Figure 2-2 shows that the layout of the on-screen display includes:
Menus across the top
Menu items for the selected menu in the left, vertical column
Input for the selected menu item

Figure 2-2 On-Screen Display Layout
The following scenario explains how to use the five buttons on top of the MultiLink with the on-screen display. Figure 2-3 shows a flowchart of the actions described in the following steps.
To display the on-screen display, press the select button on top of the MultiLink.
To choose a menu, press the right or left directional button.
Notice that each time you press one of these buttons:
The menu icon highlight moves left or right, corresponding to the directional button you push, showing which menu is selected.
The title of the menu, located just under the menu icons, changes according to the menu selected.
The menu items in the left vertical column change according to the menu selected
To choose a menu item in the selected menu, press the up or down directional button.
Notice that each time you press one of these buttons:
The menu item selection indicator moves up or down to show you which menu item is selected.
The name of the menu item, located just under the menu title, changes according to the menu item selected.
The menu item controls in the center of the on-screen display, change according to the menu item selected.
To use the menu item controls of the selected menu item:
Press the select button.
Notice that the menu icon highlight and the menu item selection indicator turn gray and the items in the center of the on-screen display turn white to indicate the current selection. Now the directional buttons interact with the menu item controls instead of navigating through menus and menu items.
To change the menu item settings, press any of the directional buttons corresponding to the white arrows in the on-screen display window.
To end adjustment of the display controls, press the select button.
Notice that the menu icon highlight and the menu item selection indicator turn white while the menu item controls change color to indicate the current selection. The directional buttons now interact with the menu and menu item choices again.
You now have a choice for your next on-screen display action:
To use a different menu item or switch to another menu, use the directional buttons. Refer to steps 2 through 5 above.
Alternately, to exit the on-screen display immediately and save your settings, press the select button. You must press the select button before using any directional buttons or you will not exit the on-screen display.
Figure 2-3 shows in flowchart style how to use the select and menu buttons, as described in "How the On-Screen Display Works". Darkened buttons on the keypad illustrations show how the state of the on-screen display changes according to user input. The Overlapped Modes menu item on the General Menu is shown as an example; all other menus and menu items also follow this flowchart.
Figure 2-3 Flowchart of On-Screen Display Interaction
On the bottom of the on-screen display shown in Figure 2-2 are four settings:
Resolution
Analog or digital input status
Zoom status
Line rate
The resolution is expressed by the number of pixels drawn in the horizontal and vertical directions. For example, the highest resolution is 1600 X 1024, which means 1600 pixels are drawn on each horizontal line and 1024 horizontal lines are drawn.
Your video card sets the resolution. Consult your video card manual for instructions on changing the resolution.
The input to the MultiLink can be either analog or digital, as shown in Figure 2-4.
Figure 2-4 Analog and Digital Input Icons
The sine wave icon shown in Figure 2-4 represents an analog input, the square wave icon represents a digital input.
You specify the input by setting the analog and digital (A/D) input switch, shown in Figure 2-5, located on the back of the MultiLink.
Figure 2-5 Analog and Digital Input Switch
Line rate indicates the speed with which horizontal lines are drawn out of your video card to the MultiLink. Although the numbers you see for line rate will be close to the numbers pictured in this manual, they may not match exactly.
The refresh rate on the MultiLink is fixed at 60 Hz (except in special situations for legacy BIOS mode compatibility). If the refresh rate on the video card is incompatible with the refresh rate of the MultiLink, the LED on top of the MultiLink flashes yellow.
The Zoom feature enables you to do the following (see Figure 2-6):
Maintain the proper aspect ratio of the image, which leaves black borders to the left and right of the image (Standard View)
Stretch the display so that the image fills the entire screen (Wide View)
Figure 2-6 Zoom Settings
Figure 2-7 shows the icons for the Standard and the Wide zoom settings, respectively, that are found toward the bottom of the on-screen display.
Figure 2-7 Zoom Status Icons
To set the zoom, use the Zoom menu item in the General menu, as shown in Figure 2-8.
Figure 2-8 Zoom Menu Item
This section explains the menu items in each of the on-screen display menus in the following sections:
The General Menu, shown in Figure 2-9, adjusts common flat panel display settings and user preferences.
Figure 2-9 General Menu Overview
The General Menu has the following menu items:
Z oom - Changes the size of the displayed image, as described in "Zoom Status", between Wide and Standard View.
O verlapped Modes - Chooses the correct resolution for display in special situations. Certain combinations of timing modes are indecipherable to the MultiLink. In such cases, you may need to override the MultiLink's settings through the Overlapped Modes menu item. Consult Table A-8 for a listing of the affected timing modes.
S creen Position - Changes the horizontal and vertical position of the entire image on the flat screen display.
I nformation - Provides general information about the MultiLink.
Force Detect - Causes the MultiLink to redetect and optimize the current screen image.
The Image Menu, shown in Figure 2-10, provides menu items that affect screen appearance parameters.
Figure 2-10 Image Menu Overview
The Image Menu has the following menu items:
B rightness - (Analog only) Adjusts the overall brightness of the whites and the blackness of the blacks in all three color channels (R, G, and B) simultaneously. Also known as offset adjustment.
C ontrast - (Analog only) Simultaneously adjusts the intensity of all three color channels (R, G, and B) in the image.
C olor Gain - (Analog only) Same as contrast adjustment except that red, green, and blue channels may be adjusted independently.
B acklight - Controls the overall intensity of the 1600SW backlighting system.
C olor Temperature - Adjusts the backlight white point from warm, reddish-white to cool, bluish-white.
The On-Screen Display Menu, shown in Figure 2-11, affects the position, time-out setting, size, and language of the on-screen display.
Figure 2-11 On-Screen Display Menu Overview
The On-Screen Display (OSD) Menu has the following menu items:
OSD Position - Moves the on-screen display vertically and horizontally.
