5-1-4 Remote Computer monitor blanking operation
For an overview of Remote Computer monitor blanking, see Section 2-13, “Remote Computer monitor blanking
overview.” Monitor blanking on the Remote Computer is provided for security, so that the primary user’s desktop
session on the Remote Computer is not visible if a monitor is connected to the Remote Computer.
Monitor blanking is supported on the following Remote Computers:
• HP xw Personal Workstations running Windows XP Pro with nVidia graphics and a graphics driver version
of 8.1.6.7 or later
• HP bc2000 and bc2500 Blade PCs running Windows XP Pro with a BIOS version of 1.06 or later
On the supported computers, the default behavior is that the Remote Computer monitor will blank to black when
the user connects and logs in. The Remote Computer monitor will unblank when the user disconnects or logs out.
Below are several additional details on monitor blanking on HP xw Personal Workstations:
• The one element on the monitor that does not go blank is the cursor.
• Blanking can take up to two seconds from the time the primary user logs in or reconnects until the time that
the monitor is actually blanked.
• The HP xw Personal Workstations also block input from a directly-connected keyboard and mouse when
monitor blanking is occurring. When keyboard or mouse input is received by the Remote Computer, the
monitor will enter the display powersave mode, and the cursor will be blanked as a result.
• An exception to input blocking is the CTRL-ALT-DEL key sequence. When this sequence is received by the
Remote Computer from a directly-connected keyboard, the Remote Computer desktop will display the login
dialog on the Local Computer. The Remote Computer monitor will remain blank while this occurs but the
monitor will exit its powersave mode, and keyboard input will become unblocked until this dialog is
dismissed.
If monitor blanking is enabled but the Remote Computer is unable to blank the display (because, for example, the
computer is not one of the supported computers listed previously), a warning dialog is displayed on the Local
Computer (see Figure 5-7).
