Output Rate selection

3Output Rate button — The Output Rate button (figure 3-4) cycles through the available output screen resolutions. Use this button to select the “sweet spot” resolution of the connected video display device. The switcher defaults to a refresh rate of 60 Hz with each resolution selection using the Output Rate button.

Eight IN1508 output resolutions are not available from the front panel. These eight resolutions can be selected using the menu system (see “Resolution selection box”, on page 3-21) and SIS commands (see chapter 4, “Serial Communications”). The eight output resolutions not available from the front panel are:

852 x 480

1400 x 1050

1280 x 768

1280 x 800

1440 x 900

1680 x 1050

Figure 3-4 — Output Rate buttons

The Output Rate LEDs indicate the selected resolution.

If any of the rates not available from the front panel are selected using the menu system or SIS commands, no Output Rate LED is lit.

The Output Rate button allows you to select the resolution only; the refresh rate defaults to 60 Hz for each front panel resolution selection. You can select a different refresh rate using the menu system; see “Refresh Rate selection box” later in this chapter for details.

There is a 1-second delay between selecting an output resolution from the front panel (the desired Output Rate LED lights) and the selected change taking effect. This ensures that the screen does not try to change resolutions while you cycle through the available resolutions to the desired setting.

The switcher reports the selected resolution for approximately 3 seconds on the connected output display.
