Using dual monitors refers to using two physical display devices to increase the viewing space running on a single computer. Microsoft Windows Operating Systems and Mac OS X now support dual and multiple monitor configurations. Setting up dual monitors is easy. However, it requires the user to add a second video card or install a video card that can support a dual head or two separate physical outputs. The following instructions are for those with only one video card installed in their computers: Make sure that the computer is working Read More

Electronic ink is one of the technologies being researched today to replace the paper-and-ink method of printing reading materials. As of the present, there are two companies developing this technology and they're E-Ink and Xerox. The main components of this technology are cavities or microcapsules, the substance or ink enclosed in this capsule and the negatively charged pigmented balls or chips inside the capsules. These three components make possible the rearrangement of microcapsules on the "paper" upon command. The digital book will contain ultra-thin plastic paper. This will be composed Read More

Dot Pitch – also called Phosphor Pitch or Line Pitch – refers to the distance between the sub-pixels (phosphor dots) or liquid crystal display cells of the same color inside a display screen. Expressed in millimeters, technically, dot pitch is the sum of the size of a triad and the distance between the triads (a triad is a cluster of three phosphor dots, colored Red, Green, and Blue inside a CRT screen). A smaller dot pitch means a smaller distance between the phosphor dots and hence better image clarity. Unfortunately, Read More

Tele-Immersion or the use of holographic environments is the next step to Internet video conferencing. This technology aims to produce a computer-generated central environment in which participants from anywhere in the world can interact as if they are in the same room. This technology goes far beyond the current technological combination of telephony and Internet by videoconferencing to exchange data. Tele-Immersion will be able to address the line-of-sight limitations of the current video conferencing technology. With the use of holographic environments, users will be able to have an unrestricted view Read More

VGA (Video Graphics Array) cables connect computers with monitors or television sets. The cables are based on the graphics standard that IBM developed on personal computers sold during the 1980s. Since that time, almost all personal computers that are built to support the Windows operating system (OS) incorporate support for VGA connections and the more advanced HD connections that have been created and implemented since VGA was first invented. How do VGA Connections Work? The term VGA refers to the type of cable used to connect a display to a Read More
