CHAPTER 1 OVERVIEW

1.1 Introduction

The crescent walls is a video wall consists of multiples monitors (2x2 / 3x3 / 4x4) lied

together contiguously or overlapped in order to form one large screen. Use typical

display technologies and mullion compensation with seamless output feature.

For the video display orientation configuration, the crescent walls allow you to configure

the video with landscape mode – a widescreen landscape display mode. The output

picture will adjust the aspect ratio to available display size automatically. The picture will

not be deformed due to a rotation.

Moreover, while color temperature dramatically affects the picture qualities of an LCD

monitor. User can simply use the default values to restore the picture basic quality. A

good understanding of the meaning of color temperature will enable better adjustments

of LCD monitor picture quality.

Through the HDBT (QW-202S / 303S / 404S) or HDMI (QW-202H / 303H / 404H)

interfaces you can optional select output transmission mode featuring a high resolution

and low energy consumption. Typical application areas of the crescent walls include

information displays, digital advertisings, meeting rooms and so on.

Or use the Cat.5e cable to connect the output RJ-45 jacks on the rear panel to the LINK

jack of the Extender. Through the Extender, you can extend the transmission distance

and over-long configuring the projector, video recorder, display or multiplexer to your

Switcher.

Figure 24: Output Connection with RJ-45 Interface

6.2.1 HDBaseT Output Port

QW-Series supports RJ-45 registered jacks using 8P8C modular connector, which

specifies the physical male and female connectors as well as the pin assignments of the

wires in a telephone cable. (A common LAN cable is available.)

6.2.2 Output Cable

HDBaseT was designed to provide Full HD performance up to 70 meters of Cat.5e or

superior cables. In a typical installation, the cable is stretched to its full length between

the HDBaseT Transmitter device and the HDBaseT Receiver device. However

sometimes, especially, in demonstrations or in a lab environment, the cable is rolled

randomly in small turns for convenience. The randomly rolled UTP cable suffers

additional signal impairments (compared to straight cable) and therefore the maximal

operating reach might be reduced. When a Cat.5e cable is randomly rolled, it is

recommended to limit its length to approximate 50 meters. Rolling a Cat.5e cable around

a 70cm fixed diameter plastic drum has just a minor effect on the FEXT (Far End Cross

Talk) when compared to a fully stretched cable.
