Other more recent adapters input and output PC RGB signals and LCD monitors using USB as a video input interface. PC input generally involves one of the following five interface types: D-Sub for analog connections DVI-D for digital connections DVI-I, which is compatible with both analog and digital connections and HDMI and DisplayPort, representing the new generation of interfaces for digital connections. Major categories here are inputs from PCs and inputs from audio-video (AV) devices. LCD-monitor interfaces also can be grouped by differences in the devices connected. (Image quality also depends on the quality of the route used in converting from analog to digital.) A digital interface offers superior image quality, since it transmits digital signals without conversion or modification. This series of actions can degrade image quality. An analog interface involves the additional steps of conversion of digital signals within the PC to analog signals for output and the conversion of these analog signals back into digital form by the LCD monitor receiving the signal. The interfaces for LCD monitors designed for use with PCs can be grouped into two categories: analog interfaces, carryovers from the days of CRT monitors, and the digital interfaces developed more recently. Input terminals of the FlexScan EV3237 monitor But first, let's give an overview of the types of interfaces available. In this article, we'll discuss, one by one, the main interfaces used today. More than likely, significant numbers of users encountering LCD monitors incorporating multiple input systems have wondered what to connect to which terminal. LCD monitors feature a wide range of video input interfacesĭriven by demand for higher-resolution monitor environments and the proliferation of high-definition devices, the types of video input interfaces ("interfaces" hereinafter) found in LCD monitors continue to proliferate. Information about Mini DisplayPort was added to the English translation. Note: Below is the translation from the Japanese of the "IT Media LCD Display Course II, Part 2," published on December 16, 2008. Image quality and ease of use are likely to depend on how well the user knows and uses the unique characteristics of each interface when connecting the appropriate devices. With the emergence of a new generation of interfaces, growing numbers of LCD monitors feature multiple and different interfaces.
