Fine Sync: To fine-tune the position and other image attributes, choose Fine Sync f\
rom the ADVANCED menu and 
press ENTER. This displays the Fine Sync sub-menu, shown in Figure 4-18.\
Figure 4-18: Fine Sync Sub-Menu
V Position: This control adjusts the vertical position of the image with\
in 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 wi\
thin the designated image area, up to 25 
percent of the image width left or right.
Phase (RGB or Component sources): This control adjusts the phase of th\
e pixel sampling clock relative to 
the incoming signal. Adjust the phase when an RGB or Component image sti\
ll shows shimmer or “noise” after 
Tracking has been optimized.
Tip
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 44) to remove high-frequency 
noise from the signal.
For best results, use a good test pattern such as a smooth gray consisti\
ng 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 m\
ore than one point. Use either setting in 
such cases.
Tracking (RGB or Component sources): Tracking determines the frequency\
 of the pixel sampling clock, indicat-
ed by the number of incoming pixels per line, so that all pixels generat\
ed by a particular source are sampled.  
Steady flickering or several soft vertical stripes or bands across the e\
ntire 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 v\
oltage level of the H9080FD Sync signal 
detection circuitry. 
Sync Level adjustment is occasionally necessary when a DVD player or HDT\
V 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 set\
ting is 240 mV and should rarely require ad-
justment.

HDMI 1/HDMI 2: Enables or disables the HDMI 1 and HDMI 2 sources.
RGB: Enables or disables the RGB source.
Comp 1/Comp 2: Enables or disables the Component 1 and Component 2 sourc\
es.
Video: Enables or disables the Composite video source.
NoteIf either Component 1 or Video is enabled, SCART must be disabled.
S-Video: Enables or disables the S-Video source.
SCART: Enables or disables the SCART RGBS source.
NoteIf SCART is enabled, both Component 1 and Video must be disabled.
Auto Power Off: Set Auto Power Off to On to have the H9080FD turn itself off after 20 mi\
nutes of inactivity (no 
source signal present).
Auto Power On: Set Auto Power On to On causes the projector to automatically power up \
when AC power is 
present. If the projector is plugged into a switched AC outlet, this all\
ows the projector to be turned on using a wall 
switch instead of the remote control unit. If you do not need this capab\
ility, set Auto Power On to Off (this is the de-
fault setting).
Rear Projection: This control reverses all images and menus, and is necessary when the pr\
ojector is used in rear-
projection applications. The default is Off.
Ceiling Mode: This control flips the image so the projector can be used in ceiling mou\
nted installations.
Trigger-1: Select the primary screen trigger condition:
LED: Triggers the screen when the LED is turned on.
16:9, Letterbox, 4:3, or 4:3 Narrow: Triggers the screen when the select\
ed aspect ratio is active.
RS232: Triggers the screen when the RS232 “Trigger On” command is \
received. 
Trigger-2: Select the secondary screen trigger condition (see descriptions for Tri\
gger 1).
NoteTrigger commands are deactivated when a PIP source is active.

5.1 Cleaning the Intake and Exhaust Vents
Cleaning the Air Vents
The projector intake/exhaust vents should be cleaned every 500 hours of \
operation. In dustier environments, it is  
recommend to clean the projector more frequently to prevent damage or pe\
rformance degradation.

5.2 Troubleshooting Tips
Table 5-1 provides some general guidelines for troubleshooting problems \
you may encounter with the H9080FD. If the 
suggested solutions fail to resolve the problem or if you encounter an i\
ssue not described here, please contact Vivitek 
Technical Support.
SymptomPossible Cause(s)Solution
The projector does not turn on.The H9080FD is not plugged in or 
the AC outlet is not active. 
•Ensure that the H9080FD is 
plugged in and that the AC outlet 
is active.
•
The remote control does not work 
correctly. 
The batteries have run out. 
IR code set mismatch between  
remote control unit and projector. 
•
•
Replace the batteries.
Press and hold the LIGHT and 
ENTER remote control buttons si-
multaneously until the remote control 
back-lighting “blinks” (approximately 
five seconds). Then, try again.
•
•
The projector is on and OSD menus 
appear, but there is no video image 
on-screen. 
Incorrect source selection.
Source component is not turned on.
Source component is connected 
incorrectly or not at all.  
•
•
•
Select the correct source. 
Turn on the source. 
Check cable connection from 
source component to projector. 
•
•
•
A projected image from a DVD is 
split or otherwise scrambled. 
DVD player is connected to the 
Component input and set to pro-
gressive scan mode. 
•Turn off progressive scan on the 
DVD player. 
•
Image is blurred. The lens is not correctly focused. •Adjust the focus with the remote control. •
Image is too bright and/or lacks defini-
tion in the bright areas of the image. 
Contrast is set too high. •Lower the contrast setting. •
Image appears “washed out” and/or 
dark areas appear too bright. 
Brightness is set too high.•Lower the brightness setting. •
Colors in the image are swapped; 
for example, reds appear blue or 
vice versa. 
The Red/Pr, Green/Y or Blue/Pb 
outputs from the source are con-
nected to the wrong inputs on the 
H9080FD.
•Ensure that the source outputs are 
connected to the correct H9080FD 
input.
