The very fast response time (25 ms) provides excellent suitability for video and gaming
applications. The monitor enclosure is made of steel and hardened glass, which provides excellent stability and
strength. When supplied with raiser and foot, the integrated hinge means you are able to manoeuvre the monitor for
optimal viewing angle and comfort. Alternatively the monitor can be placed on a wall by means of the supplied wall
bracket. The monitor is fully DDC 2 compliant, which makes installation very easy.

Connections:

• Analogue VGA (D-Sub connectors via 2 meter integrated cables)

• S-video (Y/C) (Mini-DIN connectors via 2 meter integrated cables)

• Composite (CVBS) (RCA connectors via 2 meter integrated cables)

Features:

• Graphical based OSD menu controlling all the functions of the monitor.

• High display quality : High contrast ratio, wide-viewing angle and High-speed response time.

• High brightness with the 4-CCFL backlight lamps

• Intelligent Digital Image processor

• Wide Input Voltage Range +9 VDC - +15 VDC

• Accepts refresh rates of between 56 Hz and 75 Hz.

• VESA DPMS power saving compatible.

• DDC Ver.2 Compliant

• Low power Consumption

• Separate H/V sync, Composite H/V Sync or Sync-on-green (SOG)

• Fully PAL and NTSC compatible Video inputs

2. Important Information

When using the ventura 150TFT x4 with Windows NT, it is recommended that the refresh rate be set to 60 Hz before
connecting the monitor.

Please save the packaging. It has been designed to provide optimal support and protection for the monitor during
transportation.

• ventura 150 TFT x4 (15” x 4)

Accessories box including:

• PSU (120 Watt)

• Powercord

• Wall bracket

• Users manual

• Glass cleaner & screen wiping cloth

4. Unpacking, Placement and Set-up (PC)

After the box has been opened, remove the accessories box.
Bend the cardboard flaps outward and get hold of the whole cabinet. Gently lift the monitor out of the cardboard box.
Most convenient is to be two persons. Remove the foam sidepieces and the plastic bag.

Wall solution: The wall must be able to safely support 20 kg.

Make sure both the computer and monitor are turned off before connecting the monitor.

• Connect the monitor to the computer by means of the supplied VGA cable. (Attached to the monitor)

• Connect the PSU to the monitor and AC outlet.

• Turn on the computer and monitor.

• mermaid ventura x4 15” consists of 4 identical mermaid ventura 150 AT screens.

• mermaid ventura 150 TFT is plug & play compatible via VESA DDC1/2B. Windows 98, ME and XP will

recognise this and self configure.

• mermaid ventura x4 can be connected to 4 separate video cards:

- installed in the same PC

- installed in up to 4 different PCs

- or you can use a multiscreen video card with up to 4 output terminals.

• When using the mermaid ventura 150 TFT x4 with Windows NT, the computer needs to be started in VGA
mode the first time. Log on as administrator and set the resolution to 1280x 1024 and refresh rate to 60 Hz.
The computer can then be started in normal mode.

Appendix F: Definition of viewing angle.

• Viewing angle is defined as the range,
measured at a 90° angle from the display
surface plane in the centre of the display
panel to that angle, where the the
contrast value has dropped to 10:1 or
5:1. The exact value is defined by the
manufacturer of the panel. See drawing.

• Viewing angle is defined both vertically
and horizontally.

• The two sets of parameters are rarely

The panels in the mermaid ventura 150 x4 have the folloing data:

Because two panels are mounted on top of each other in pairs, it’s impossible to
experience the same contrast value on all 4 panels, when looking at them from
the same angle.

Please remember, thet even though the viewing angles are fairly high, the
contrast is allowed to drop from e.g. 300:1 to 5:1 within that range, which
equals to 60 times!

The user will typically experience this as colour differences and backlight
uniformity differences.

All 4 panels are taken from the same production batch, which ensures the best
panel homogeneity as possible.
