DVI to VGA Converter Overview
What is DVI?
DVI is a digital visual Interface which is developed to transfer a video source from one device to the other. DVI or Digital Visual Interface is used to send an uncompressed form of video signals to the display component. This port in the laptops or CPU is used to connect the video signals to the display source, such as to monitor, LED, projector, etc.
This interface can be used to send three types of data.
- DVI-A (analog signals only)
- DVI-D (digital signals only)
- DVI-I (both digital and analog signals)
Pins in a DVI port
There are 29 small pins on the DVI port that can be used to send both digital and analog signals of a video from one source to the other.
The 24 pins that are present in a rectangular pattern are called digital signal pins. On the right side, there is a formation of the plus sign and four squares. These five ports are used to send the analog signal. The analog signal pins are named C1, C2, C3, C4, and C5.
What is a VGA?
Abbreviation for VGA is Video Graphic Array. The VGA or Video Graphic array has 15 small pins. Their pins are arranged in a regular sequence of 5 pins in each row. This VGA port is given in many devices such as laptops, projectors, monitors, television, and LEDs.
Short VGA cables can send the perfect video signals, whereas long VGA wire may result in the distortion of some of the signals while traveling.
Resolution of VGA
The maximum resolution provided by VGA or Video Graphic Array is 640 x 480, and the frequency of these signals send by VGA is 60 Hz.
Use of DVI to VGA convertor
If your laptop has a DVI port and the monitor has a VGA converter, you don’t have to buy a new monitor to match the ports whereas, you can just buy a DVI-I to VGA cable or adaptor. DVI-I works by sending standard analog signals to the VGA connection. Thus the monitor screen will display exactly the same results as the laptop provides it.
Which are better cables or adaptors?
DVI to VGA adaptors are much better than the cables. This is because, while signals are traveling through the cables, distortion may occur. This distortion can become the cause of the loss of signals, and you may not be able to see the video properly.
