7. Known issue: Monitors continually revert
to incorrect display topology
■
The 'Use client topology settings…' check box is selected in
the PCoIP Host Software Settings dialog.
This check box determines whether or not the zero client
display topology gets reported to the Windows operating
system.
■
An incorrect display topology is specified and enabled on the
zero client.
The On Screen Display (OSD) for TERA2 zero clients enables
you to configure the display topology. For example, you can
specify the display layout (for example, monitors arranged in
a horizontal row), and the video port, rotation and
resolution for individual monitors.
When these four conditions are true, the zero client reports a
specific display topology to the PCoIP Host Driver Function
running on the host computer. In turn, the PCoIP Host Driver
Function configures the Windows desktop to match the display
topology reported by the zero client.
Note:
For details about the PCoIP Host Driver Function and
Host Software Package, see the Teradici PCoIP Host
Software for Windows User Guide. For details about the
zero client On Screen Display, see the
Teradici PCoIP Zero
Client and Host Administrator Guide

7.3 Solutions
To resolve this problem, apply
the following pages.
If the user is likely to connect to their remote workstation from
different zero clients (for example, in a hot desking
environment), the most reliable solution is to implement fix 1.

This section describes how to resolve a display problem that can
affect PCoIP systems that use TERA2 hosts and zero clients.
Note:
For other known TERA2 display issues, see
Application Note 064, Display problems affecting TERA2
PCoIP systems, available on the Support > Downloads page
of the Amulet Hotkey website,
7.1 Symptom
When using multiple monitors, the user experiences display
problems associated with a misconfigured display topology.
(Here, display topology refers to the physical arrangement of
the monitors.)
For example, four monitors may be physically arranged in a grid
or box (two rows of two monitors), but the computer interprets
mouse movements as though the monitors were arranged in a
single row.
This problem happens when a user connects to their usual
PCoIP host from a different zero client (for example, in a hot
desking environment). The problem reoccurs even after the user
specifies the correct topology in the Display applet of Windows
Control Panel.
7.2 Cause
This problem can occur when the following four conditions are
true:
■
The PCoIP Host Driver Function is enabled on the PCoIP host.
This function is an optional feature supported on PCoIP host
cards with firmware 2.0 or later. It enables you to use the
PCoIP Host Software package on the host computer.
■
The PCoIP Host Software package is installed on the host
computer.
This package is a collection of drivers and applications that
allow Windows operating systems to interact with Teradici
PCoIP host processors and PCoIP zero clients. In particular,
the package includes the PCoIP Host Software Settings
dialog.
