remain clearly defined. It can be particularly useful if a significant "Noise Reduction" adjustment has caused
the image to appear too soft. Adjust until the display is as sharp as desired, keeping in mind that because
"Detail" adds some high frequencies back into the image, it can also re-introduce a certain degree of noise.

operates in the post-sampling digital domain with a more subtle effect. Higher settings are most useful for
clearing up noisy RGB images such as those from a PC. Adjust as desired, keeping in mind that reducing noise
(which reduces high frequencies) may also soften the image.
Color Space Option
Color Space

color components of an analog input signal or certain digital signals connected to
INPUT 1, INPUT 2, INPUT 5, or INPUT 6 are decoded for accurate color in the
display. Although color space for these analog signals is automatically determined by
the projector, in some circumstances you may wish to override this and manually set a
specific color space.
NOTE: For most digital signals or for signals connected to INPUT 3 or INPUT 4 , the color space function is
entirely automatic and the drop-down list disabled.
The current color space appears in the
• Select RGB unless you are using component video at INPUT 1, 2, 5, or 6.
• Select YPbPr (Video) with a standard definition televised signal (SDTV)
• Select YPbPr (HDTV) with a high definition televised signal (HDTV).
NOTE:
When certain RGB signals are first connected, the projector may not initially recognize them as RGB and
incorrectly decodes 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, then define a new channel for future use.

NOTE:
Best results are obtained with defined channels. Otherwise, switching from one video source to another
can sometimes cause slight disturbances in the display, indicating that the Auto function is struggling.
Recover by briefly selecting a different video standard, then going back.

decoded video images only. Enter a check mark (default) in most instances to activate the decoder's AGC
circuit and ensure properly bright images. Delete the check mark 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.
