USER GUIDE
7.1.4 SVGA
SVGA in 800x600 mode is compressed both horizontally and vertically to
640x480 resolution. This feature is convenient when displaying irregular
images (like pictures, scanned images and coarse graphics).
Regular images (patterns, text and fine line graphics) may look distorted
due to the downsizing. In this case, we recommend setting up the
computer in 640x480 mode for a precise image.
7.1.5 VGA TEXT
VGA text is compressed correctly from 720x400 to 640x400 mode when
the image is positioned correctly. The characters maintain their shape, as
every ninth pixel is dropped horizontally between each character. Selecting
MCGA in the menu will deactivate the text compression. This is useful for
320x200x256 MCGA images.
7.1.6 BUILT IN SPEAKERS
Stereo speakers are built into the LCD projector that provide ample sound
for small and medium sized rooms. External speakers may be used for
better freedom in positioning of the speakers. An external amplifier may
also be connected to the speaker outputs for added boost to the external
speakers.
7.1.7 MULTISTANDARD TV SYSTEMS
The LCD projector incorporates a unique multistandard video decoder that
works with all major TV systems. NTSC, PAL and SECAM are
automatically detected. See the Technical Data section for TV system
compatibility. (The PAL M and N systems are not supported).
7.1.8 PAL/SECAM ASPECT RATIO
The NTSC system maps directly to a 640 x 480 resolution display. The
PAL and SECAM systems need aspect ratio conversion to fit correctly. The
LCD projector automatically adapts to NTSC, PAL and SECAM formats
and adjusts the aspect ratio accordingly.
7.1.9 ON SCREEN DISPLAY (OSD)
The OSD is an information system that in plain text echoes your RC and
MENU selections on screen in real time. The OSD information is displayed
in the lower left corner of the screen. The OSD feature may be set visible
or hidden through the menu system.
