Epson 755c - PowerLite XGA LCD Projector Bulletin d'information sur les produits

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:

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.

•

a. Establish a wireless communication between the PC and

projector via 802.11a signal.

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.
