The flicker of interlaced video is not suppressed totally for the latter setting. 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.
The latency of the system is ¼ of a frame for progressive input and progressive output when I/O locked.
If the output is free running the latency is oscillating between ¼ of a frame and 1 frame. Switching on
PTZ adds one frame of latency. Switching on warp adds another frame of latency. If an interlaced video
signal is processed in Best Picture mode, this will add one more field of latency. In Low Latency mode
this extra field of latency is avoided.

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.
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 to switch on/off the OSD menu. The LCD menu – which is a
copy of the OSD menu – then serves as the only menu navigation monitoring device.

Network Settings
The factory default is DHCP.
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 needs 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.
Note: When changing from DHCP to Static mode or vice versa it is strongly recommended that
HQView-5xx is powered down after such a change, then powered back up, so that it is properly
recognised by other devices on the network.

Factory Defaults
This button lets you restore all settings to the default values of the HQView-5xx, this, provide a means to
get back to a known (good) system state. A request will come up and ask to confirm prior to actual
restore.
3.11.8.
Operation Mode
This menu item is only available on a HQView-510/520/530. It allows to choose between the regular
multiple unit mode with blend and warp and a PiP mode. Selecting the PiP mode will effectively boot the
HQView-510/520/530 to emulate a HQView-500S. A HQView-500S has PiP/PaP/PoP capability but no
edge blend. The Operation Mode can be switched back to Multiple Unit.
