Digital Visual Interface (DVI ) is a video interface for transmitting data. In the PC area, DVI is developed as a standard for connection of TFT monitors to the graphics card of a computer. In the field of consumer electronics, there are TVs that process with a DVI input signals from digital sources such as computer or DVD player.
DVI allows the simultaneous transmission of analogue and digital image data. To be distinguished from VGA are the digital standards DVI , HDMI and UDI and the analog TV connections RGB, S -Video, and F -BAS to connect a TV to the graphics card. A more compact, variation which is sometimes used in laptops is mini VGA.
Serial Digital Interface
The Serial Digital Interface (SDI) is primarily for transmission of uncompressed and unencrypted video data over coaxial cables or fiber optic cables. It is used mainly by the professional television studios and broadcasters.
The SDI interface is specified by the Society of Motion Picture and Television Engineers (SMPTE), and represents a further development of methods such as the PAL or NTSC the analog video standards.
The Unified Display Interface ( UDI) should be imported in 1986 VGA port, and compatible with digital DVI port, in addition to transfer audio data, and (like the DVI compatible HDMI) support the HDCP signal encryption.
DisplayPort
DisplayPort (DP) is a standardized by VESA and royalty-free connectivity standard for the transmission of video and audio signals. Applications are mainly for monitors and televisions to computers and similar devices, which can be handled by MAC Computer Repairs Sydney.
Standard resolutions
In the IT sector both graphics standards exist, as well as typical resolutions for graphics modes (most are standardized on the VESA). The screens are factory-set to a gamma of 2.2 and adjusted to a color temperature of 6500K. Using color management software, these values ​can be (if displayed) customized.
In flat panel technologies, the maximum resolution is particularly important because it has been designed for its native resolution. Whereas with a CRT monitor all resolutions do not fit exactly over the native shadow mask and is blurred.
A flat screen can pose its maximum resolution with 100% clarity that most other resolutions need to be interpolated, and thus appear less sharp. Exceptions are resolutions, in which no intermediate pixels have to be interpolated, such as half or a quarter of the native resolution. The native resolution is given in the type description of the monitor that is handled by MAC Computer Repairs Sydney.
Screen dimensions
The screen size is the size specification of the screen and always refers to the diagonal size of the picture tube, this is slightly larger than the viewable screen usually.
