DVI (Digital Video Interface) is a video connector designed by the Digital Display Working Group (DDWG), aimed at maximizing the picture quality of digital display devices such as digital projectors and LCD screens. It is crafted for transporting uncompressed digital video information to a display screen. It is partly compatible with the High-Definition Multimedia Interface (HDMI) standard in digital mode (DVI-D), and VGA in analog mode (DVI-A).DVI Vs. Older Video Technologies

The CRT (Cathode Ray Tube), is the vital component in most computer monitors and televisions. It is responsible for the images that we see in monitors and television sets.How a CRT Works
The main component of a CRT is the picture tube. The tube is wide at the front and narrows at the rear end. The shape at the rear end can be compared to a bottle neck. The rear end consists of a negative charged filament, which is known as cathode. The filament is enclosed in a vacuum and is the most...

An LCD or Liquid Crystal Display is a flat, thin display device consisting of any number of pixels aligned in front of a reflector or source of light. The LCD has been widely hailed as a prized invention as it is relatively cheap and it consumes less power to function than competing techologies, making it almost indespensable in battery powered electronic devices. Types of LCDs
LCDs are broadly classified as either transmissive or reflective, depending upon the position of their source of...

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...

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

Video Cards, also known as display cards, graphics cards, graphics controllers, or graphics accelerator cards, convert binary data (bytes) into display images. The Video Card is part of the usual complement of computer hardware. The Video Card is external to the motherboard; that is, it is a separate hardware that is attached to the motherboard through the appropriate slot.
Some motherboard variants have an integrated graphics processing capability. Computers with such motherboards do not...

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...

1024x768 is one of the most popular resolutions for PC video screens.
The 1024x768 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.1024x768 on the Web
As of 2006, OneStat reports that 56.15% of all web site visitors are using 1024x768 resolution. This makes...

SVGA is an acronym for Super Video Graphics Array and covers a wide range of computer display standards used in the manufacture of computer monitors and screens.
The SVGA standard was designed by VESA, the Video Electronics Standards Association.
When using SVGA as a direct comparison to other display standards such as XGA (Extended Graphics Array) or VGA (Video Graphics Array) the standard resolution referred to as SVGA is 800*600 pixels.
When the SVGA standard was first defined it...

The full form of QVGA is Quarter Video Graphics Array. It is also known as Quarter VGA in short. QVGA is a type of resolution whose dimensions are 320x240 pixels. The QVGA display is normally found in devices such as mobile phones and PDAs. The display is also common on other handheld devices such as game consoles.Resolution
Most of the time, the display is in the portrait layout as opposed to the landscape layout; they are also known as 240x320 displays because they are taller than they are...
