VGA - you should know
- VGA stands for "Video Graphics Array" and was introduced in 1987 by IBM.
- The maximum resolution that can be transmitted by VGA is 1920 × 1200 pixels.
- For nearly twenty years, VGA was the absolute Standard.
- Therefore, VGA in monitors, graphics cards, projectors, and TV, it is common to devices far.
- Pure analog signals are transmitted, resulting in a loss of quality for long cables and strong sources of interference will result.
DVI - The innovations of the VGA-successor
- DVI stands for "Digital Visual Interface".
- DVI allows the Transfer of a digital (DVI-D) or analog (DVI-A) Signal, or both (DVI-I). In addition, two digital signals can be transmitted (Dual-Link).
- It can be up to twice 1920 × 1200 Pixel transfer.
- You can distinguish DVI-D, DVI-A and DVI-I both as a Single as well as Dual-Link optical. Wikipedia provides for all connections, a figure and a diagram of the PINs.
- Due to its compatibility to VGA and HDMI to DVI is widely used. As it (transfers, such as VGA) image only, it is increasingly being displaced by purely digital, multi-media HDMI.
- Of the HDCP copy protection on HD-DVDs and BluRays under the playback via analog outputs, such as VGA and DVI binds-A. you will need DVI-D, DVI-I, Dual Link, or HDMI.
