VQS-200 is equipped with digital HDMI and SPDIF outputs plus baseband analog NTSC/PAL
CVBS video output and analog L-R audio outputs.
This model does not support 3G or HD-SDI output formats. However the signals in these formats,
can be produced by connecting the VQS-200 HDMI output to any suitable HDMI-to-SDI
converter.
The VQS-200 is a turn-key system, based on Western Digital "WD TV HD Media Player"
platform. It is supplied complete with pre-installed audio-video content. No additional software
installation is required for normal system operation.

3Operation
VQS-200 is supplied fully configured with all settings in the correct positions. However, it is
highly recommended to check the set-up as described in "Configuration and Customization"
section.
To select the desired content for play-out use the remote control - browse folders tree and find the
content file name.
Different types of content are accessible after choosing the corresponding menu:
·Static or Dynamic VQL test patterns and live clips are accessible via "Video" menu.
·Static photos and slide-shows are accessible via "Photo" menu.
·Audio test patterns are accessible via "Music" menu.
In each of these modes not all folders are visible - only the folders with the content of the selected
type. For example, in "Photo" mode only the folders containing static pictures are visible, other
folders, e.g. containing only video files or only audio files are hidden.
Picture below shows all folders with all types of the pre-loaded VQL content.
This picture serves for information only and it is not displayed on-screen; folders structure may
vary depending on release version.

Operation
VQS-200 User Manual 6

Important Note:
For truly objective evaluation of the display device performance the internal VQS-200 scaler
should be bypassed, i.e. neither spatial nor temporal internal scaling should be applied.
It means that HDMI resolution, interlace mode and frame rate should be set exactly matching the
media content file parameters.
For example, the appropriate 1080i60 HDMI mode should be selected via submenu
"Settings/Audio-Video/Display Resolution" before playing out "VST 1080i 60" test pattern .
Once selected, the HDMI mode is preserved, even when the VQS-200 is switched on/off by the
Remote Control "Power" button.
However, if the external PSU or main supply line is disconnected, the unit may return to HDMI
"Auto" (safe) mode, which is the lowest resolution available for this particular display. In such
case the submenu "Settings/Audio-Video/Display Resolution" should be re-visited to set or
restore the desired HDMI mode.
Below is brief description of Remote Control functions
"Option" button is important because it enables OSD messages and menus, in particular - media
info, pan & zoom controls, repetition mode (play once, repeat same file, repeat all files in the
folder), etc. This button works as on/off toggle switch.
For full description of Remote Control keys and functions, navigation instructions and complete
list of on-screen menus see separate document "WDAVN00BN UserManual.pdf".

4Configuration and Customization
VQS-200 Recommended Settings
From "Home" page select "Settings/Audio/Video" menu
In the Display Resolution sub-menu below "Auto" means "safe mode", i.e. the lowest available
resolution, which is seldom needed.
After the unit is powered on first time and "Home" menu appears on screen (in small size),
"Audio-Video/Display resolution" should be changed to native display resolution, interlace and
frame rate, e.g. 1080p60.

Configuration and Customization
VQS-200 User Manual 8

In the "Aspect Ratio" sub-menu select native display aspect ratio - typically "Widescreen".
"Normal" here means 4x3 display aspect ratio, which is seldom needed.
Important: In the "Settings/Audio-Video" sub-menu selection of "Composite" instead of
"HDMI" disables HDMI output and vice versa. This selection should be taken with caution
because for few seconds the menus will be visible only on the display connected to "CVBS"
output. On the other hand, VQS-200 automatically detects connections to HDMI and CVBS
outputs, so once the HDMI output is disconnected the CVBS output is automatically enabled (if
connected) - overriding the menu settings. Consequent disconnection of CVBS output
automatically restores HDMI output.
Important: In Settings/Audio-Video" menu the selection of "Stereo" as an audio output disables
digital SPDIF output, but if "Digital" audio output is selected, the analog stereo output may be
still present. In the latter case all L+R stereo formats and some types of 5.1 surround sound
content (not all formats) can played on both digital and analog output, but on analog output 5.1
content is converted to L+R (down-mix).

Selection of NTSC/PAL in "Settings/Audio-Video" sub-menu affects only the format of auxiliary
analog CVBS output, it does not affect HDMI output.
In the "Settings/Photo" sub-menu "Keep as original" option is recommended because it prevents
unwanted scaling (distortion) of photo images.
In the "System Settings/Browser Display" menu select "List mode", because it allows navigation
via folders and long file names.
Selection of "Thumbnails mode" is not recommended because the current version of VQS-200
system does not support navigation by thumbnails.
