 Fixed error message displayed by the NVIDIA utility

Failure Symptom

When starting Quick Wireless/USB Display/NS Connection on a PC with
the built-in NVIDIA graphics chip (ex.ThinkPadT61 NVIDIA Quadro NVS
140M/NVIDIA Quadro FX 570M Display Driver), the NVIDIA utility
displays consecutive error messages. As a result, some PCs will
experience a lock-up.

Countermeasure

Hardware acceleration level is set to 3 when Quick Wireless/USB
Display/NS Connection are being used.

Limitation

By setting hardware acceleration level to “3”, the mouse cursor flickers
more visibly than the setting of “None”. This symptom can be avoided by
unchecking the box for Transfer Layered Window on the Adjustment
performance tab in the Set Options window of NS Connection.
Note: When NS connection is being used, and the hardware acceleration
setting is changed manually, at next startup, NS connection starts with
the same setting level of hardware acceleration.

Limitation All Operating Systems

• When using EAP type of security that consumes a lot of CPU resources,
projectors may disconnect from NS connection. The solution is to click
Set Options of NS Connection and set Adjust Performance to Fast.

• It takes more time for the PowerLite 1725 / 1735W / 1825 / Pro G5150 /
Pro G5350 projectors to disconnect from NS connection as compared to
the PowerLite 1705 / 1715 / 1815 projectors, due to the limitation of the
new OS (WindowsCE) on IM-X4 projectors.

• To avoid conflicts between the Quick Wireless and other makers’
utilities, when the Quick Wireless starts, this version stops services of
the other utilities listed in the attached file (Exhibit 1). When quitting
Quick Wireless, the other utilities resume their services.

• In the network environment using IEEE 802.11 b/g standards, the
wireless connection may drop under the following conditions. Due to
specification of wireless controllers, some wireless controllers don’t send
their beacon periodically. Even if a projector is connected to a PC via
wireless, if the projector doesn’t detect the beacon for 11b signal for a
certain period (30 – 60 seconds) from the PC , the projector judges that
there isn’t any PC using the11b signal in the network and switches to
communication with11g (default) signal. On the other hand the PC still
tries to communicate with 11b. As a result, the wireless connection
between the projector and the PC drops.

Solutions to this problem:

a. Establish a wireless communication between the PC and

projector via 802.11a signal.

Windows OS

• Due to a limitation of the module VLC for the Movie Sending mode
of the IM-X4 version projectors, when IM-X4 projectors display
MPEG2 and WMV images in Movie Sending mode via NSC V2.40,
fast-forward and rewind functions cannot be used. When IM-X3
projectors display MPEG2 via NSC V2.40, fast-forward and rewind
functions can be used.

Windows Vista OS

• Multi screen display function cannot be used

• Virtual display driver cannot be installed in PC.

• When UAC (User Account Controls) screen is being displayed, the

projected image pauses.

• The Motion picture of Windows photo gallery cannot be projected in full-

screen mode.

• Still images and motion pictures from Windows Media Center cannot be

projected in full-screen mode.

• Since NS Connection can capture Layered windows, the tool bar of NS

Connection is projected.

•

•

• When projecting images via NS Connection, mouse cursor might blink

depending on PC specification.
