Section 3: Operation
BRIGHTNESS
Increases or decreases the amount of black in the image (0-100). For best results, keep close to 50. Start with a
high value and decrease so that dark areas do not become black. Conversely, high brightness changes black to
dark grey, causing washed-out images.
COLOR SPACE
Determines how the color components of an analog input signal are decoded for accurate color in the display.
Useful only for analog signals and certain digital sources. Although color space for these analog signals is
automatically determined by the projector. You may wish to override this and manually set a specific color
space. For some signals, the color space function is entirely automatic and the pull-down list is

disabled.
The current color space appears in the Image Settings menu. Press E
• Select RGB unless you are using component video
• Select YPbPr (Video) with a standard definition televised signal (SDTV).
• Select YPbPr (HDTV) with a high definition televised signal (HDTV).
When certain RGB signals are first connected, the projector may not recognize them as RGB and will

incorrectly decode their color information as YPbPr (video). These signals can include:
• RGB signals in NTSC, PAL, SECAM frequency ranges.
• Scan-doubled sync-on-green.
• Scan-quadrupled sync-on-green.
For these signals, change the color Space to RGB, and then define a new channel for future use.
VIDEO OPTIONS - S
This submenu is used with video sources only.
• ENABLE DECODER (AGC)
AGC affects decoded video images only. Enter a checkmark (default) in most instances. Activate the decoder's
AGC circuit to ensure properly bright images. Delete the checkmark if a decoded video image exhibits strange
color artifacts such as stripes in highly saturated colors, indicating an incompatibility between this source and
the AGC.
• VIDEO STANDARD
For most video standards available in the world, the projector automatically detects the incoming horizontal
and vertical frequencies and sets the projector's processing of this signal to the corresponding standard. The
current video standard name appears in the Video Options submenu, and includes an "A" if it is auto-detected.

standard forces the projector to process the signal according to this standard.

disturbances in the display, indicating that the Auto function is struggling. Recover by briefly selecting a
different video standard, then going back.
