DVI

=DVI=

DVI stands for Digital Visual Interface.[#1] This was developed by the DDWG, the Digital Display Working Group.[#1] It is a video inteface standard which carries uncompressed video data or signals in a digital format.[#1] DVI compresses the video into a digital data then recovers the data when playing the video and therefore shows a video of high quality.[#1] This technology is widely used in LCD displays or digital projectors.[#1] When the DVI sends data to the display the data is sent as binary numbers.[#1] The binary numbers represent an illumination of the pixels in the display and when the displays reads this data, it accurately shows each pixel with the given data.[#1] While DVI technology is accurate because it signals every pixel to show an exact color, using analog signals may affect nearby pixels' display and show a lower quality display because of electrical noise and analog distortions.[#1] (Good job paraphrasing) This is why you might see blurry displays and noises in older televisions while modern displays are vivid, less blurry and shows videos ( almost same ) typo maybe? to its original quality. DVI technology is more widely used in computer displays while HDMI (High-Definition Multimedia Interface) technology is used for high definition media such as Blu-ray, DVD players, in video game consoles and some computer monitors.[#1,2] There are actually no difference in DVI and HDMI if they were compared in the quality of the video and the encoding of the video, but HDMI also carries audio data as well as the video.[#1,2] You might want to cite which websites you got your information from. Just do that weird little number thing corresponding to your references. Plus, that way I dont have to read through the whole website to find where you got your info. Thanks



Single Link and Dual Link are availiable in DVI-D (Digital Only) or DVI-I (Digital & Analog).[#2] Single Link has pins to pas through digital video signals while Dual Links have additinal pins for second set of digital data.[#1] By using two TMDS (Transition Minimized Differential Signaling) transmitters, Dual Link cables double the power of transmission and increases the speed and signal quality.[#2,3]

DVI-D cables send digital signals which provide a faster and higher quality image than analog signals.[#2] DVI-A cables send DVI signals to an analog display such as VGA monitors. However, it is recommended to use digital cables because there is quality loss from digital to analog conversion.[#2] DVI-I cables are integrated cables which is capable of transmitting both digital and analog signals. Therefore it is more universal or able to use in various situations.[#2]

I made some corrections by labeling my sources and adding more information about Single/Dual Link and types of DVI connectors - Steve
