3. Configure the output as follows:

a. Set the output resolution/refresh rate of the first MGP (the unit farthest from the display) to your output display’s native rate.

NDo not set this unit to the DVI background rate.

b. Set the output rates of the second and, if appropriate, the third MGP to “DVI Background Rate.” This setting uses the incoming DVI resolution and pixel clock as the output rate of the MGPs, which is essential in order to avoid any sampling of the incoming DVI signal.

NBy default, the resolution provided in the Extended Display Identification Data (EDID) is the last selected factory rate. To manually set the resolution information provided in the EDID data, see the Set EDID information SIS command on page 4-9.

c. If it has not yet been selected, set the background of the second and third MGPs to “DVI Background.” When you do this, these two units set their output rates to the DVI background rate.

NThe DVI background rate remains in effect, even when the background is not set for DVI Background. This prevents any image scrambling on the display when the system is switching between the DVI background source and other background images or colors.

4.Configure the windows on all the MGPs as follows:

a. Mute the windows on the second and third MGPs to view the windows on the first MGP only.

b. Set the size and position of the four windows on the first MGP, either manually or by selecting a window preset.

c. Save the configuration for the first MGP as a window preset, for future use.

d. Unmute the windows for the second MGP in the chain and configure them as desired. Save this window configuration as a preset.

NThe default presets provided with the MGP have no background selected. For the second and third MGPs in the chain, you must select “DVI background” as the background.

e. Repeat step d for the third MGP if appropriate.

NIt is recommended that you save the window configurations on the second and third MGPs with the same preset number. This is required if you are using the Preset Selector software for both MGPs, because the Preset Selector recalls the same preset number for all MGPs that have been added to it.

Refer to the Windows-based control software help file for information on

using the Preset Selector.
