1. Introduction

The mermaid ventura 170 TFT and 181 TFT are state of the art high-tech flat panel TFT monitors,
incorporating high quality TFT-LCD panels with maximum resolution of 1280x1024. They are
based on the newest technology with high brightness 4-lamp CCFL backlight units. The very fast
response time provides excellent suitability for video and gaming applications. The monitors are
made of steel and hardened glass providing excellent stability and strength. The integrated hinge
and high adjustment means you are able to manouvre the monitors for optimal viewing angle and
comfort. The monitors are fully DDC 2 compliant, which makes installation very easy.

• Internal passive speakers (2watt x 2 ch. / 8 ohms)

2. Important Information

• When using the ventura 170 TFT and ventura 181 TFT with Windows NT, the computer needs
to be started in VGA mode the first time. Log on as administrator and set the resolution to
1280x1024 and refresh rate to 60 Hz. The computer can then be started in normal mode.

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

3. Content of the Box

• ventura 170 TFT (17”) or ventura 181 TFT (18.1”)

• ”Quickstart” card

Accessories bag including:

• PSU (45 Watt)

• Powercord

• Speaker cable

• Users manual

4. Unpacking, Placement and Setup (PC)

Note: To avoid condensation, please wait ½-1 hour, before operating the unit.

After the box has been opened, remove the accessories bag.
Bend the cardboard flaps outward and turn the box upside down, which will ensure the inlay foam
with the monitor is able to slide out. Do not drop the content on the floor.
Remove the foam side pieces and the plastic bag.

The monitor needs to be placed on a smooth and stable surface. This surface must be able to
safely support 15 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.

beneath the monitor

• ventura 170 TFT and ventura 181 TFT are plug & play compatible via VESA DDC1/2B. Windows
98, ME and XP will recognise this and self configure.

• When using the ventura 170 TFT and ventura 181 TFT with Windows NT, the computer needs

to be started in VGA mode the first time. Log on as administrator and set the resolution to
1280x1024 and refresh rate to 60 Hz. The computer can then be started in normal mode.

Appendix D: Video Mode Support

The ventura 170 TFT and ventura 181 TFT support any video mode at inputs within the following
ranges:

• The signal sample frequency on the input ≤ 80MHz

• The horizontal sync frequency between 30KHz and 60KHz

The modes are detected when presented to the input and previous alignments for setup are
automatically recalled. A true multi-sync monitor emulation is implemented.
The factory preset supported modes include:
