Dual Head Setup
Procedure:
30 VMIVME-7807/VME-7807RC Hardware Reference Manual
2.6.2 DVI Connectors
The DVI connector has twenty‐four pins that can accommodate up to two TMDS
links and the VESA DDC and EDID services. The DVI specification defines two
types of connectors (see Figure 1):
• DVI‐Digital (DVI‐D) supports digital displays only (used on the
VMIVME‐7807/VME‐7807RC)
• DVI‐Integrated (DVI‐I) supports digital displays and is backward compati‐
ble with analog displays (not supported)
The VMIVME‐7807/VME‐7807RC use the DVI‐I connector with a single TMDS
link. The DVI‐I interface accommodates a 12‐ or 24‐pin DVI plug connector or a
new type of analog plug connector that uses four additional pins, plus a ground
plane plug to maintain a constant impedance for the analog RGB signals.
2.6.3 Dual Head Video
The VMIVME‐7807/VME‐7807RC are capable of driving two monitors at the same
time using the Intel 855GME GMCH. The graphics controller allows the use of
one digital monitor connected to the VMIACC‐0590/ACC‐0590RC or
VMIACC‐0586/ ACC‐0586RC RTMs, routed out the rear I/O P2 connector. The
second is a standard SVGA monitor connected to the front panel of the
VMIVME‐7807/VME‐7807RC, using a standard DB15 connector.
1. Boot Windows 2000.
2. In the windows desktop right click.
3. When the menu appears, scroll down to the 'Graphics Options' and then
click on 'Graphics Properties'. The Intel 82852/82855GM/GME graphics con‐
troller properties menu will appear. From this menu you can choose the dis‐
play mode of choice.
The monitors can be displayed in several modes:
• Monitor Mode ‐ In this mode only the SVGA monitor is displayed.
• Digital Mode ‐ In this mode only the Digital is displayed.
• Dual Display Clone Mode ‐ In this mode both the SVGA and the Digital
monitors are displayed, with the desktop the same on both monitors.
• Extended Desktop Mode ‐ In this mode the two monitors are displayed as
one desktop.
4. After making your choice click 'OK' to apply the changes.
NOTE
When using the Dual Head mode, the maximum resolution for each
monitor is 1600x1200 for the 855GME. Refer to manufacturer's
documentation for the resolutions of each monitor used.
