Organic Light-Emitting Diodes (OLED) are considered by many people as the next step in display technology, with the potential of replacing current plasma or LCD large-screen televisions with ultra-slim, ultra-light screens that can be folded when not in use. They are currently being used in small screen displays such as computer monitors, digital cameras and car TV screens. The next stage of development is to create commercially-viable, large TV screens. LED and OLED In order to understand OLED, one needs to start with the light-emitting diodes or LED. Simply put, Read More

Files ending in .daa extensions are movie files specially formatted to facilitate downloading from the internet. Converter software is required to view .daa files. What do you need to know about .daa files? Generally, movie files are in .avi or .mpeg format. When storing movies digitally on CD or DVD, however, it is preferable to use .iso or .bin/.cue format. Although it is possible to send and receive large movie files of this type, their large size means it is a tedious and cumbersome task. One solution is to convert Read More

1024×768 is one of the most popular resolutions for PC video screens. The 1024×768 resolution was introduced as an enhancement to the Super VGA (SVGA) standard. 1024 is the horizontal resolution and represents the number of columns supported by the video card and monitor; 768 is the vertical resolution and represents the number of rows (or lines) supported. 1024×768 on the Web 1024×768 was the most popular screen resolution in use by our site visitors for many years. As of 2012, the wider 1366×768 resolution has taken the top spot Read More

DVI (Digital Visual Interface) cables implement the DVI video interface standard in order to enable high visual quality displays on LCD flat panel and digital projector displays. The Digital Display Working Group (DDWG) created this standard as a succeeding technology to the traditional VGA connection standard. DVI connector technology carries uncompressed digital video and is partially compatible with the High-Definition Multimedia Interface (HDMI) standard in the DVI-D (Digital) mode and with VGA when operating in analog mode (DVI-A). How does DVI Work? The DVI interface uses a digital protocol that Read More

Vision Station is a computer display technology developed by Elumens that provides 180 degrees of viewing angle for its users. Current computer screens have at most a 50-degree field of view and needs the user to move the controller in order to see the images that are not on the screen. This motion is unnatural because in the real world, users use their peripheral vision to see things beyond the direct line of sight. This new display technology will address this limitation of standard computer monitors. With Vision Station, users Read More

LCoS (Light Crystal over Silicon) is a technology used in display systems. LCoS shares some elements with LCD and DLP (Digital Light Processing) displays. As such, LCOS systems are not exactly new though it was only recently that commercial manufacture became viable. The best way to understand LCoS television is to understand the process. How LCoS Works The process starts with an intense light beam that's passed through a condenser lens. This lens has the task of focusing and directing the beam. It has a filter which ensures that only Read More

The video card is a necessary component added to the computer to allow for graphics to play at higher qualities. The better the video card, the more that can be done on a computer. Many elite gamers spend hundreds, if not thousands, to have the most up to date graphics card installed on their computer because it ensures that the quality of their gaming is pristine. Knowing what video card you currently have makes it easier to determine what type to get in the future since graphic cards need to Read More

SLI (Scalable Link Interface) is a multi-GPU parallel processing application for computer graphic cards developed by Nvidia. Simply, it allows two or more video graphic cards to be connected together for one output. The technology was formerly used by 3dfx Interactive with the Voodoo2 video cards as the Scan Line Interleave in the late 1990s. Later when Nvidia bought out 3dfx Interactive, SLI was not used. However, starting in 2004, SLI was renamed as the Scalable Link Interface and was planned to be widely used with computers with a PCI Read More

When you choose to install a new video card, the first thing you’ll need to do is select the video card based on the type of video card your motherboard supports.   Common graphics card types are the following: PCI (Peripheral Component Interface) AGP (Accelerated Graphics Port). Some cards also support AGP Pro, which requires additional power, and therefore additional pins on the motherboard’s AGP slot. Most cards, especially on newer PCs, will be PCI Express graphics cards, also known as PCIe. Check with your computer or motherboard’s manufacturer to Read More

A VGA extender is a device that extends a VGA cable’s range without sacrificing quality. VGA extenders are often used in audio/video applications that require a source to be connected to a display device over a long distance. They are usually in the form of a small box and can often extend a VGA connection over 300 feet. VGA extenders may also include other features, such as converting VGA signals to other types of cables. How VGA Extenders Work VGA extenders are made for VGA (Video Graphics Array) cables and Read More
