Dual Monitors
This section describes how to set up and configure dual monitors (OptiPlex
FX170 only).
1 While the unit is turned off, attach both monitors to the thin client.
2 Turn on the thin client.
3 Upon bootup, the display will be mirrored on both monitors.
4 From the DeTOS Desktop, select DeTOS  Control Panel .
5 Click the Display icon on the left-hand side of the Control Panel , under
System.
6 You will be presented with display settings for Color Depth and Screen
Blanking options. These settings apply to both monitors associated with
the DVI-1 (bottom) port and the LVDS1 represents the DVI-2 (top) port.
7 To adjust specific properties for each monitor, click the Monitors button
along the top of the Control Panel . You will then be presented with the
names of the two monitors attached to the terminal. The exact names will
vary depending on how they are detected on that particular terminal. For
an OptiPlex FX170 thin client, the VGA1 port is typically associated with
the DVI-1 (bottom) port and the LVDS1 represents the DVI-2 (top) port.
