Test Pattern:

When the OSD menu is off the test pattern can be toggled through by pressing the up and down keys

of the keypad. For unit control through a web browser or to set up a certain default test pattern a list

box to choose the pattern from is provided. Custom test patterns loaded into the file system of the unit

through the web interface, can be accessed through the same means.

The speed of the moving test pattern can be changed. Also, the foreground and background colour

and the line width of the moving cross test pattern can be changed in this menu.

Switching Transistion:

When switching input channels 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 said devices. By default HQView is in auto frame rate

switching and I/O lock mode. 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.

The switching transition of HQView can be set to Freeze, Blank, Fast Fade and Slow Fade. Freeze

halts the prior channel image until the new channel image is stable. Blank switches the output to show

a black screen instead of the last channel image. Fast and slow fade have the prior channel image

faded out and fade into the new channel video image once it is stable.

3.11.4. Display Mode

The “Display Mode” can be set to either Low Latency or Best Picture. In Best Picture optimum image

processing is applied, whereas 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.

3.11.5. Menu Settings

This menu provides items to change the menu position and menu display time, i.e. 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. Either all keys or the menu and

menu navigational keys 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 (HQView-

500S/510/520): Keypad is locked. Press Menu/Up/Down to unlock. When successfully unlocking the

keypad the message shows up: Keypad unlocked.

HQView-530 has an additional menu item compared with HQView-520 to switch off the OSD menu.

The LCD menu – which is a copy of the OSD menu – then serves as the only menu navigation

monitoring device.

3.11.6. Network Settings

The Network Settings menu allows to configure the HQView-5xx TCP/IP address. Under Address Type

a static or DHCP leased address can be chosen. The static address and Netmask need to be entered

manually.

The Network Settings menu has a section with information on the DHCP Status and IP address

assigned to the board, as well as the fixed MAC Address programmed into the HQView-5xx. The

DHCP status is Off when static assignment is used or it displays an address when DHCP has leased

an address accordingly or it is None assigned if the lease was not successful.
