INTRODUCTION
1.1.
General Introduction
HQView-2xx is a very flexible image scaler developed specifically for driving large screen displays from
SD-SDI, HD-SDI and 3G-SDI serial digital source.
HQView-2xx features state of the art digital image processor which provides market leading HD& SD
per-pixel multiple Iow-angle motion-adaptive de-interlacing and automatic film pull-down correction for
3:2 and 2:2, significantly outperforming the capabilities of benchmark competitor products.
HQView-2xx features excellent image processing algorithms for the very best scaling, film and video
noise reduction and MPEG artefact reduction.
HQView-2xx uses a high performance SDI de-serializer with cable equalization.
The output format can be set to I/O Lock mode where it locks the output frame rate to the input frame
rate dynamically without frame rate conversion so as to reduce system latency, or it can be set to a fixed
output frame rate for driving basic screens which are not 50Hz-compatible. Furthermore, the HQView-
100 can be set to have the output resolution match the input resolution to preserve aspect ratio. A Low
latency mode with non-motion adaptive reduced processing is available to further reduce latency.
Outputs are available in DVI digital formats.
HQView-2xx (type V2) supports Pan, Zoom and Tilt to select a part of the input image, fill the screen
and pan within it.
HQView-210 features embedded warp functions to adjust the image in a projection scenario to match a
rotated, tilted or curved screen. For 9:16 portrait mode signage special predefined warp maps are
available to rotate and stretch a video image to fill a +/-90° rotated display panel.
System control is via an OSD controlled by keys on the front panel or through an intuitive ‘Windows’
application connected via a normal RS232 serial port or via TCP/IP (ethernet).

Introduction
The HQView-2xx units have the input connector on one side of the housing and the output connector as
well as the communication ports on the opposite side. The keypad for controlling HQView-2xx is located
on the input connectors side. The active input is indicated by their corresponding triangles lit green.
1 –Keypad with three keys for OSD menu navigation (Menu, Down and Up).
With the Menu key the OSD menu is activated. The up/down keys are used for OSD menu navigation.
To exit the OSD menu or any submenu navigate go to the Exit item and press the menu key. To access
a submenu navigate to it and press the menu key. To apply a change go to the menu item, press the
menu key and make a parameter change with the up/down key. Confirm the change by pressing the
Menu key. This will also bring you back to the submenu.
The active channel is indicated by the associated green lit triangle(s). This is always the 3G-SDI input.
With the following multiple key presses further functions can be applied:
Keypad unlock: Up/Down
Set output and fallback output mode to VGA: Menu/Up
Mode reset: Menu/Down
Factory reset: Menu/Up/Down
A factory reset can also be applied when pressing the factory reset key combination at power up. The
keys have to be kept pressed for about 10 seconds until the 3GSDI input LED stops flashing. If the keys
are released during that 10 seconds period the system will get into Updater mode (see chapter 5) since
the Menu key is part of this key combination.

Main Menu
The main menu lists 5 sub menus. The 5 sub menus are Output, Colour, Geometry, Enhancement and
System.
On each menu page an Exit menu item is available to leave the menu or submenu. Some adjustments
are not applicable to all signal types or operating modes, in which case those non-applicable functions
will be ghosted and are not accessible via the menus.
All menus have a top status line and a bottom line indicating the firmware revision number. In the status
line the currently selected input channel is indicated and the detected mode is identified. The firmware
revision number displays the revision number of the bootloader behind BL, the revision number of the
firmware behind FW and whether it is a 200S or 210 HQView unit.
To set up your HQView-2xx it is recommended that you follow this procedure:
Choose the correct output mode and parameters to suit your screen or projector.
Set the input levels and features appropriately to optimize the appearance of your image.
Set any other parameters to suit your application.
Note: All Input parameters are specific to your chosen input channel and input signal type, they are not
global to the unit. All Output parameters are global
3.4.
Input
The list of available inputs can be scrolled through using the Up and Down keys. The new input is not
selected until the Menu key is pressed.
The list of inputs are: 3G-SDI and Test Pattern.
Test patterns can be generated by HQView-2xx without needing an input connected. When Test Pattern
is selected as the input, the required test pattern can be chosen with the menu navigation up/down keys
when the OSD menu is off.

3.5. Output
This menu contains adjustments associated with setting up outputs from the unit. Most items are
collected in the Display Type submenu. Use the up and down keys to scroll to the required item and
press the Menu key.
3.5.1. Output Mode
Settings: 640x480, 800x600, 1024x768, 1280x768, 1280x800, 1280x1024, 1360x768, 1366x768,
1400x1050, 1440x900, 1600x1200, 1680x1050, 1920x1200, 720p (1280x720), 1080p (1920x1080),
480p (720x480), 576p (720x576)
Set up the desired output resolution with output mode. The output mode setting should match the native
resolution of the imaging device to avoid double scaling.
3.5.2. Location
Settings: Front Tabletop, Front Ceiling, Rear Tabletop, Rear Ceiling
The image can be flipped to accommodate different projection scenarios as well as screens mounted
upside down.
3.5.3. Optimize for Display
Settings: DVI forced, Optimized, DVI/HDMI
Internally, the display interface processes data at a full ten bits per colour. The colour depth on the DVI-
D output is determined by the supported standard of the attached monitor or device when set to
DVI/HDMI. For DVI 1.0 and HDMI 1.1/1.2 devices it is 24 bit, for HDMI 1.3 compliant devices it is up to
36 bit.
DVI forced will output with 24 bit colour depth irrespective of the supported standard of the attached
monitor.
When the Optimized setting is enabled the output resolution is automatically set to the native screen
resolution of the attached display if the Aspect Ratio menu item was chosen to Scale or when no input is
detected. The colour depth is determined in the same way as when set to DVI/HDMI.
3.5.4. DVI Range
Settings: Default, Limited, Full
When set to Default CEA output modes have limited range, and VESA modes have full range.
Therefore, an incoming limited range mode is either passed through when the output is set to a CEA
output mode or expanded when the output is set to a VESA mode. An incoming full range mode is either
compressed when the output is set to a CEA output mode or passed through when the output is set to a
VESA mode.
If the HDMI/DVI output does not behave as expected, e.g. because the HDMI display is not evaluating
AVInfoFrames properly, the range can be changed manually.
A limited video range is only using the following greyscale for video information - 8 Bit System: 0x10 ..
0xEF, 10 Bit System: 0x040 .. 0x03BF, 12 Bit System: 0x100 .. 0xEFF.

T:[phone] F: [phone] E: [email protected] 10
3.5.5. Frame Rate
Settings: 60 Hz, 50 Hz, 48 Hz, 24 Hz, Auto
In auto mode the output frame rate follows the input frame rate as configured in the Frame Rates menu.
Signals with 24Hz, 25H, 48Hz, 50Hz input modes get special treatment, modes with other refresh rates
are displayed at 60Hz.
24Hz input modes will be output at 24Hz if the output resolution is set to either 720p or 1080p and the
Frame Rate setting in the Output Config menu includes 24Hz, otherwise it is displayed at twice the rate
if the Frame Rate setting in the Output Config menu includes 48Hz.
Otherwise a 24Hz input mode is displayed at 60Hz. 48Hz input modes will be output at 48Hz if the
Frame Rate setting in the Output Config menu includes 48Hz.
Otherwise it is displayed at 50Hz.
A 25Hz input mode is output at twice the frame rate 50Hz.
An exception to the 24/25Hz input mode treatment is if the output resolution is set to 480p. 480p is
always run at 60Hz output rate.
50Hz input modes are displayed at 50Hz output rate.
The output frame rate can also manually set to 24Hz, 48Hz, 50Hz or 60Hz if possible, i.e. such output
modes are available.
Only 720p and 1080p output modes are available with 24Hz refresh rate.
The 480p output mode is only available at 60Hz refresh rate.
For all other modes 48Hz, 50Hz and 60Hz refresh rate is available.
3.5.6. (Available) Frame Rates
Settings: 60/50 Hz, 60/50/24 Hz, 60/50/48, 60/50/24/48
Limits the possible output frame rates that can be selected. It is primarily to be able to limit the choices
available for the Auto refresh rate configuration.
3.5.7. I/O Lock
Settings: On, Off
If I/O Lock is switched off the output is run with a fixed refresh rate determined by the frame rate setting,
which deviates from the input refresh rate, even if both are nominally at the same rate. This causes
occasional frame dropping or repeat. If I/O Lock is on the output refresh rate is following the input
refresh rate. This is achieved by modulating the output clock and works if input and output refresh rate
are nominally at the same rate, e.g. when frame rate is set to 60Hz and the video input is also 60Hz. If
e.g. the video input rate is 50 Hz and the Frame rate is set to 60Hz, the output is in free run mode. The
status line of the OSD window under Sync Mode indicates if the output signal is locked to the input
signal (I/O Locked) or in free run mode (Free Run) .
3.5.8. Native Color Temp
Settings: 5500, 6500, 7500, 9300, 10000
Native Color Temp allows the user to select from pre-configured color temperatures to match the
display. If both Native Color Temp set here in the Output menu and Color Temp set in the Color menu
are set to the same value, no conversion is performed.

T:[phone] F: [phone] E: [email protected] 11
3.5.9. Output Gamma
Settings: 1.0 to 3.0 in steps of 0.1
Output gamma allows to re-gamma video signals with pre-configured gamma values to match the
display. Input gamma and output gamma both default to 2.2. If they are both set to the same value,
there is no effect on the image.
Note: If e.g. an adjustment to reduce the level of red in the image is required, select a higher number for
the (input) Color Temp in the Color menu, or a lower number for the Native Color Temp in the Output
menu.
3.6. Colour
This menu contains adjustments associated with setting up inputs to the unit. Use the Up and Down
keys to scroll to the required item and press the Menu key.
3.6.1. Black-Level Offset
Settings: 0 IRE, 7.5 IRE
Used to select 7.5 IRE black level set-up adjustment.
3.6.2. Black-Level
Settings: -50 to 50 in steps of 1
Black level controls the offset applied to the video signal.
3.6.3. Contrast
Settings: -50 to 50 in steps of 1
Contrast controls the gain applied to the video signal.
3.6.4. Saturation
Settings: -50 to 50 in steps of 1
Control of video saturation, applies to all video inputs but not computer input signals or formats.
3.6.5. Hue
Settings: -50 to 50 in steps of 1
Control of video hue, applies to all video inputs but not computer input signals or formats.
3.6.6. RGB values
This is a user-defined colour temperature setting whereby individual R,G,B gain and offset (bias) can be
set so as to accurately calibrate a particular input to the display device.
3.6.7. Colour Temp
Settings: 5500, 6500, 7500, 9300
Colour Temp allows the user to select from pre-configured colour temperatures to match the colour
temperature of the incoming signal. If both Colour Temp set here in the Colour menu and Native Colour
Temp set in the Output menu are set to the same value, no conversion is performed.

T:[phone] F: [phone] E: [email protected] 12
3.6.8. RGB values
This is a user-defined colour temperature setting whereby individual R,G,B gain and offset (bias) can be
set so as to accurately calibrate a particular input to the display device.
3.6.9. Input Gamma
Settings: Gamma 1.0, Gamma 1.5, Gamma 2.2, Gamma 2.8
Set this value to match the native gamma of the input signal. Input gamma and output gamma both
default to 2.2. If they are both set to the same value, there is no effect on the image.
3.7. Geometry
This menu contains adjustments associated with setting up position, aspect ratio and scale of the input
signal. Scale can be as simple as an overscan up to arbitrarily warping the image.
3.7.1. Horizontal/Vertical Position
Settings: in steps of 1 pixel/line
Change the positional values to match the display boarders.
3.7.2. Aspect Ratio
Settings: Scale, Preserve
The system can be set to scale the input image to a fixed output resolution or, with the setting preserve,
to choose an output resolution matching the input resolution. If no matching output resolution is
available or no input is detected, the pre-defined output resolution is used though.
3.7.3. Warp
Note: Embedded Warp is only available with HQView-210.
Submenu for warping the image. The warp applications are Keystone, 4-Corner and Rotation. Special
portrait warp applications for clockwise (90°) and counter-clockwise (270°) rotation with scaling are
provided as well.
Under the Keystone application the image can be adjusted to match a horizontally and vertically tilted
screen. Also, Pin/Barrel distortion of the lens or screen can be adjusted simultaneously.
Under the 4-Corner application all corners can be moved and the image is calculated to fit into the given
trapezoid.
The Rotation application let you rotate the image from -180 to 180 degree (one full circle). At the same
time Pin/Barrel distortion of the lens or screen can be adjusted again.
Predefined warp maps for portrait mode applications are provided. A 9:16 input image area is rotated
and scaled such that is fills a 16:9 screen.
For convenience all settings can be reset with one button provided in the submenus.

3.7.4. Picture Format
Settings: Standard, Full Screen, Crop, Anamorphic
Picture Format allows a user to select the displayed aspect ratio where the signal input is at variance
with the display panel’s natural aspect ratio. Note that some aspect ratios may not be applicable to all
signal types, in which case selecting a non-applicable aspect ratio conversion will have no effect on the
displayed image. E.g. when a 16:9 image is displayed on a 16:9 panel all settings give an identical full
screen image.
Standard preserves the aspect ratio of the incoming image and scales the image to fit into the size of
the panel. Dependant on the aspect ratio of the panel the image is either bordered by the right/left side
or bottom/top of the panel. Non-used areas of the panel are displayed black (letterboxed). Full Screen
scales the image to the size of the panel without preservation of the aspect ratio. Crop preserves the
aspect ratio and scales the image to fit the screen. Dependant on the aspect ratio of the panel either the
top/bottom or right/left areas of the image are cropped. Anamorphic scales the input image such that it
is displayed with a 16:9 aspect ratio when displayed on the screen. The image is further scaled to fit into
the size of the panel. Dependant on the aspect ratio of the panel the image is then either bordered by
the right/left side or bottom/top of the panel. Non-used areas of the panel are displayed black
(letterboxed).
3.7.5. Overscan
Settings: 0 to 10 in steps of 1
Overscan is used to slightly zoom into the image. Thus, the border area of an image is no longer
displayed on the screen. This cuts off unwanted features at the top or bottom from e.g. video images.
3.7.6. Pan Tilt Zoom
This menu provided settings to zoom and shrink the image, as well as panning within the image.
Pan Tilt Zoom (PTZ) can be switched on or off. When switching on the latency of the system is
increased by one frame. Thus, there is a difference of a PTZ setting off or on with no zoom. PTZ
settings can be saved per mode or globally, i.e. the same PTZ settings are applied when switching input
channels or changing the input mode.
The Zoom slider allows to zoom into the image or shrink it. When Aspect Lock is set to On the separate
slider for zooming vertically is greyed out and the horizontal zoom or shrink factor is used as vertical
factor as well. The aspect ratio is preserved. When Aspect Lock is Off horizontal and vertical scaling
factors can be chosen separately.
With the Pan and Tilt sliders panning within the image in horizontal and vertical direction is possible. Off
raster panning is allowed, i,e, the image can be shifted outside the active area of the display.
For convenience the PTZ settings can be reset with one button.
Note: HQView-2xx V2 excels original HQView-2xx hardware. PTZ is only available on HQView-2xx V2
hardware (check the serial number batch for HQView-2xx or HQView-2xx V2 marking, the product
name as indicated by the top label is HQView-2xx with no further extensions in either case). Firmware
for HQView-2xx V2 also operates on HQView-2xx hardware, only the PTZ menu is greyed out.

3.8. Enhancement
The enhancement menu provide image enhancement functions. Note that the enhancement settings
apply to video input signals only, not computer graphics signals.
3.8.1. Sharpness
Settings: -50 to 50 in steps of 1
Control of the sharpening enhancement filters' levels. These are peaking filters to improve high-
frequency response. Note that setting this control too high on a signal which already has good high
frequency response will cause ringing or ghosting.
3.8.2. Detail
Settings: 0, 1, 2, 3
This filter provides powerful 2D image enhancement which can be used to greatly improve detail
definition and clarity without causing image ringing or ghosting. It improves both horizontal and vertical
detail. Correct setting of the detail enhance filter can make SD signals look virtually indistinguishable
from true HD. At setting 0 the filter is switched off, with setting 3 providing the highest effect.
3.8.3. Video Filters
The video filters menu provides LTI/CTI filters and TRNR/MNR noise reduction filters.
The LTI filter enhances the sharpness of the luminance component. The CTI filter enhances the colour
sharpness of the chrominance signal by increasing the steepness of colour edges.
TRNR (Temporal Recursive Noise Reduction) and MNR (Mosquito Noise Reduction) are available for
SD input signals only. These filters reduce spatial and temporal noise as well as block artifacts.

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 HQView-2xx
can be stored under a user name. Thus, different users can store their preferred HQView-2xx 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/restored to/from a PC disc
drive. This feature is only available on V2 hardware
3.9.2. Names/Profiles
The Names/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/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 HQView-4xx 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
List box to choose a 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.
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, 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.
3.9.5. Switching Transition
When switching input channels (here 3GSDI and Test Pattern only) 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.

3.9.6. 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: Keypad is locked. Press Menu/Up/Down to unlock. When successfully unlocking the keypad
the message shows up: Keypad unlocked.
