Overscan: Some television programs are produced based on the assumption 
that older television sets may not display the outer edges of the broadcast 
picture area. 
Overscan effectively hides these inactive, outer edges of the 
image. Choose one of the following:
• Off: This setting leaves the image as-is.
•Crop: This setting adds a mask at the left and right edges of the source active 
image equal to 3% of the displayed horizontal resolution, and at the top and 
bottom edges equal to 3% of the displayed vertical resolution.
•Zoom: This setting adds a factor to the scaling of the source active image so 
that the vertical and horizontal resolutions are 106% of the size determined by 
the aspect ratio function. Anything outside of the original image area is 
removed.
Figure 4-6 illustrates the effect of each overscan setting for each aspect ratio.

Source Select: To select a video source, press  or  to highlight Source Select, 
then press ENTER. This displays the Source Select sub-menu, shown in Figure 4-7. 
The default source selection is HDMI 1. All sources that are not available per the 
source enable function (refer to 
Source Enable on page 56) are grayed out.

PIP Select: To select a PIP (secondary) video source, press  or  to highlight 
PIP Select, then press ENTER. The default PIP selection is Off.
All sources that are not available per the source enable function (refer to 
Source Enable on page 56) are grayed out.
All sources that cannot be used for PIP due to a shared electronic path with the 
Active source are grayed out. The PIP source is a saved setting for each source, 
like brightness and contrast.
If for some reason the current PIP source becomes invalid (by disabling it in the 
source enable menu, for instance), 
PIP Select automatically resets to Off.
Resync: If the projected image becomes unstable or degraded, press  or  
to highlight Resync, then press ENTER. This causes a re-acquisition of the active 
source and the PIP source, if present. It also changes any Fine Sync settings 
(described on page 53) for this timing to the default setting.

AdvancedUse the controls in the Advanced menu, shown in Figure 4-8, to perform 
advanced image adjustments. 
Figure 4-8. PD7170 Advanced Menu
Color Space: Select Color Space from the Advanced menu to choose the color 
space of the source signal for HDMI, RGB, and component connections.
•The default setting, Auto, functions as follows:
•HDMI: If the Auxiliary Video Information (AVI) infoframe contains color 
space and/or range data, the PD7170 uses that information. Otherwise, for 
RGB sources, the PD7170 uses the RGB-Video color space.  For component 
SDTV and EDTV resolutions, REC601 is used.  For other component video 
resolutions, REC709 is used.
•RGB: If Hsync or Vsync signals are present, the PD7170 uses the RGB-PC 
color space. Otherwise, REC601 is used for SDTV and EDTV sources, and 
REC709 for all other sources.
•Component: For SDTV and EDTV resolutions, the PD7170 uses the REC601 
color space.  For all other resolutions REC709 is used.
In most cases, the Auto setting determines the correct color space to use. If it 
does not, you can force the PD7170 to use a specific color space. Choose one 
of the following:
•REC709 sets the color space matrix to that defined in ITU-R BT.709.
•REC601 sets the color space matrix to that defined in ITU-R BT.601.
•RGB-PC uses RGB color space and sets black at 0,0,0 RGB and white at 
255,255,255 RGB, assuming an 8-bit image.

•RGB-Video uses RGB color space and sets black at 16,16,16 RGB and white at 
235,235,235, assuming an 8-bit image, to correspond to the luminance values 
defined in digital component standards.
Video Standard: Select Video Standard from the Advanced menu to specify 
the color system for composite video or S-Video input signals. 
Different countries use different formats for video signals. Select the appropriate 
Video Standard for your region: 
•Auto: The color systems are automatically identified and the format is set 
accordingly.
•PAL: This is the standard used in Europe, Australia and many other parts of the 
world, typically with a 50Hz frame rate. 
•SECAM: This is a standard format used mainly in France and Russia. 
•NTSC: This is the standard format used mainly in the United States and Japan.
Gamma: Select Gamma from the Advanced menu to choose a DLP 
de-gamma curve. Used correctly, the Gamma control can improve contrast 
while maintaining good details for blacks and whites. 
If excess ambient light washes out the image and it becomes difficult or 
impossible to see details in dark areas, lower the gamma setting to 
compensate. This improves contrast while maintaining good details for blacks. 
Conversely, if the image is washed out and unnatural, with excessive detail in 
black areas, increase the setting. 
•CRT sets the gamma to 2.5.
•Film sets the gamma to 2.2.
•Video is similar to Film gamma but differs in dark areas of the image to 
correspond to the function that video cameras use to create images. 
•Bright sets the gamma to 2.0.
•Graphics should only be used for computer presentations that require 
increased brightness at the cost of grayscale accuracy.
Color Temperature: Color temperature defines the “color of gray;” that is, 
adjusts the 75% white point to various color points.
To choose a color temperature setting, select Color Temperature from the 
Advanced menu. Then, press  or  to select 5500K, 6500K, 7500K, 9300K or 
Native. The default setting, 6500K, is appropriate for most situations. Higher 
settings produce a “bluer” picture; lower ones impart a reddish hue to the 
image. Select Native to disable white point adjustment of the source signal.

DLP Frame Rate: Select DLP Frame Rate from the Advanced menu to choose 
the output frame rate. You can have the PD7170 automatically determine the 
optimum frame rate, or you can force it to use a specific frame rate. 
 
•The default setting, Auto, frame locks to the main source if it has a vertical 
refresh rate of between 48 and 62Hz. Vertical refresh rates of from 24 to 31Hz 
are doubled. Frame rates between 31 and 48Hz and greater than 62Hz are 
converted to 60Hz.
•Select 48Hz to force the output frame rate to 48Hz. Use this setting to 
eliminate 2:3 pull-down judder with 60Hz film-based sources.
•50Hz and 60Hz force the output frame rate to 50Hz and 60Hz respectively.
Color Gamut: Select Color Gamut from the Advanced menu to select a color 
gamut (range) that may be different from the default color gamut. 
Each setting defines the precise hue of each primary (red, green and blue) and 
secondary (yellow, cyan and magenta) color component used to generate 
the millions of colors produced in displays. Changing either or both of these 
numbers changes the hue of the color and relocates the “triangle” for possible 
colors. For example, changing the x/y coordinates for red moves the color 
closer to either orange or violet, which in turn affects all displayed colors having 
a red component.
•Auto automatically chooses the appropriate color gamut:
•SMPTE C for NTSC, 480i and 480p sources. 
•EBU for PAL, SECAM, 576i and 576p sources.
•REC709 for all other sources.
•REC709 chooses the REC709 color gamut.
•Select SMPTE-C to choose the SMPTE-C color gamut.
•Select EBU to choose the EBU color gamut.
•Select Native to use REC709 for cyan, magenta, and yellow and uncorrected 
values for red, green, and blue. 
Table 4-3 lists the x- and y-coordinates for each primary and secondary color 
component. 
If PIP is active, the PD7170 converts the PIP source frame rate 
to the same frame rate as the main source.

DynamicBlack: Select DynamicBlack from the Advanced menu to enable (On) 
or disable (Off) the DynamicBlack actuator in the optical engine. DynamicBlack 
uses a dynamic iris that modulates light to the DMD based on the actual 
content of the video material. Planar recommends that you disable 
DynamicBlack before adjusting Brightness, Contrast or other image settings. 
Adaptive Contrast: Adaptive Contrast enhancement expands the light and 
dark portions of an output image according to the mean luminance of the 
input image. 
RGB Adjust: To remove any trace of color from the white areas of the projected 
image, choose 
RGB Adjust from the Advanced menu and press ENTER. This 
displays the RGB Adjust sub-menu, shown in Figure 4-9.

•Gain: Use the Gain controls to correct color imbalances in the bright areas of 
the image. A good way to do this is to use a test pattern consisting mostly of 
solid white areas, such as an 80 IRE “window” pattern. If the white areas 
contain traces of red, green or blue, decrease the Gain for that color.

•Offset: Use the Offset controls in the RGB Adjust sub-menu to correct color 
imbalances in the dark areas of the image. A good way to do this is to use a 
test pattern consisting mostly of dark gray areas, such as a 30 IRE “window” 
pattern. If the gray areas contain traces of red, green or blue, decrease the 
Offset for that color.
The Gain controls increase or decrease the full-scale input range; the Offset 
controls shift the entire range, resulting in a change in brightness. 
Fine Sync: To fine-tune the position and other image attributes, choose Fine 
Sync from the Advanced menu and press ENTER. This displays the Fine Sync 
sub-menu, shown in Figure 4-10. 
Figure 4-10. Fine Sync Sub-Menu
•V Position: This control adjusts the vertical position of the image within the 
designated image area, up to 25 per cent of the image height up or down.
• H Position: This control adjusts the horizontal position of the image within the 
designated image area, up to 25 per cent of the image width left or right.
• Phase (RGB or Component sources): This control adjusts the phase of the 
pixel sampling clock relative to the incoming signal. Adjust the phase when 
an RGB or Component image still shows shimmer or “noise” after 
Tracking has 
been optimized. 
Generally, higher Gain settings reduce the image contrast; 
higher Offset settings reduce the image brightness.Note

For best results, use a good test pattern such as a smooth gray consisting of a 
clear pattern of black and white pixels, or a similar “half on, half off” graphic 
image. Adjust the slidebar until the image stabilizes and each pixel is clearly 
defined. You may notice that you can stabilize the image at more than one 
point. Use either setting in such cases. 
• Tracking (RGB or Component sources): Tracking determines the frequency of 
the pixel sampling clock, indicated by the number of incoming pixels per line, 
so that all pixels generated by a particular source are sampled. 
Steady flickering or several soft vertical stripes or bands across the entire 
image indicates poor pixel tracking. Proper pixel tracking helps ensure that 
the image quality is consistent across the screen, that aspect ratio is 
maintained and that pixel phase (see above) can be optimized. 
• Sync Level (Component sources only): Select Sync Level to adjust the 
voltage level of the PD7170 Sync signal detection circuitry.
Sync Level adjustment is occasionally necessary when a DVD player or HDTV 
source signal drops “below black” (for example, during scenes with 
explosions or when subtitles are present) and causes the projector to 
temporarily lose sync. If the 
Sync Level from the source is persistently too low, 
the projector won’t sync with the source at all. 
The range is from 50 to 256 millivolts (mV) inclusive. The default setting is 
240
 mV and should rarely require adjustment.
Adjust the Phase after adjusting Tracking (see below). If 
some shimmer from a video or HDTV source persists, use the 
Noise Reduction controls (described on page 46) to 
remove high-frequency noise from the signal.
