3.13.4. 

Flicker Filter 

Note: This feature and the corresponding sliders are only available when  VP-794 is operated in LED 
or  LCD  and  Plasma  mode  to  be  set  under  Output/Display  Type/Display.  Also, 

this  feature  is  only 

available when the Display Mode is set to Low Latency

. In low latency mode the motion adaptive 

de-interlacer is switched OFF and the Flicker Filter is used to achieve a decent image quality. 
 
The Flicker Filter reduces interlace horizontal line edge bounce or flicker when scan converting from 
an interlaced input format to a progressive output signal. By choosing the filter strength and recursion 
mode it is possible to choose between higher levels of flicker reduction or better motion reproduction. 
By default the filter is on.  
 
Filter  Strength  controls  the  filter  weighting  of  prior  field  versus  current  field.  Recursion  chooses 
between  vertical  filtering  of  current  and  prior  input  fields,  or  current  field  and  recursive  data  output 
from filter during prior field. 
 

3.14. 

System 

This  selection  contains  functions  which  are  more  applicable  to  system  operation  than  to  picture 
adjustment.  
 

3.14.1. 

User 

Settings: USER 1, 2, 3, 4 

A predefined setting stored under a user name can be selected. Several settings of the VP-794 can be 
stored  under  a  user  name.  Thus,  different  users  can  store  their  preferred  VP-794  settings  and  recall 
these profiles by picking up their user name from this menu. 

Note: Using the Web interface, (any number of) settings can also be stored and restored to and from a 
PC disc drive.  
 

3.14.2. 

Names and Profiles 

The  Names  and  Profiles  menu  provides  input  masks  to  rename  the  generic  input  channels  and  user 
names. User names and input channel names can be changed to any word with a maximum of 12 alpha 
numeric characters with a value range of 0-9, A-Z and blank.  

The Names and Profiles menu allows the user to store profiles under a certain user name. It also allows 
to  copy  user  profiles  by  loading  a  profile  stored  under  one  user  name  and  save  it  under  another  user 
name. Reset Profile allows to restore default VP-794 settings for the currently selected user. 
 

3.14.3. 

Input Config 

Inputs can be configured through the following sub-menus: 

VGA Setup: 

Submenu for adjusting analog computer video. A button for automatic setup of frequency and phase of 
the sampling clock is provided. This automatic adjustment is strongly recommended. Frequency (Clock) 
and phase can also be altered manually. 

DVI/HDMI Setup: 

The  DVI-I  connector  will  accept  either  DVI-D  or  VGA  analog  inputs.  The  DVI-I  channel  can  be 
configured accordingly. 

The equalisation of the DVI interface can be boosted to allow for extended cable length.  

The automatic HDMI and DVI Color Space and Range settings can be overwritten in this menu. Range 
can be set to limited video mode or full range. The color space can be set to RGB or YCbCr. 

The  DDC  can  be taken off line. When setting HDCP Input to OFF HQView pretends to be non HDCP 
compliant forcing the source to not encrypt data which is not copy protected.
