User manual

3.9. System
This selection contains functions which are more applicable to system operation than to picture
adjustment.
3.9.1. User
Settings: USER 1, 2, 3, 4
A predefined setting stored under a user name can be selected. Several settings of the VP-791 can be
stored under a user name. Thus, different users can store their preferred VP-791 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.
3.9.2. 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 saving it under another user
name. Reset Profile allows to restore default VP-791 settings for the currently selected user.
3.9.3. Test Pattern
Settings: Grey V Bars, Grey H Bars, Aspect Test, Multi Test, Warp Adjust, SMPTE, PLUGE
When the OSD menu is off the test pattern can be toggled through by pressing the up and down keys of
the keypad.
3.9.4. Display Mode
The “Display Mode” can be set to either Low Latency or Best Picture. In Best Picture optimum image
processing is applied, in Low Latency mode the lowest latency is achieved. The flicker of interlaced
video is not suppressed totally for the latter setting. Thus it has the disadvantage of conventional CRT
TVs, but also their advantage of almost no delay in response, which is important for applications such
as gaming, simulation or imaging in medical treatment.
3.9.5. Switching Transition
When switching input channels (3GSDI and Test Pattern) by default the last frame of the prior displayed
image is frozen and displayed until a stable image of the new input channel can be shown. The
switchover process is supposed to be as seamless as possible. The source and monitor add switching
noise due to unforeseeable activity of the firmware in those devices. By default HQView is in auto frame
rate switching and I/O lock mode is ON. In order to get a best smooth switching result with the source
and monitor I/O lock and auto frame rate switching have to be switched OFF in the Output>Display Type
menu.
3.9.5. Menu Settings
This menu provides items to change the menu position and menu display time, the time after which the
OSD is switched off again with no user interaction. OSD Messages can be activated and deactivated.
The menu language can be altered and the keypad can be locked. To unlock the keypad a combination
of keys has to be pressed at the same time. The locking of the keyboard is accompanied by the
message: Keypad is locked. Press Menu and Up and Down to unlock. When successfully unlocking the
keypad the message shows up: Keypad unlocked.
