HDMI Display Port VGA DVI | Which Better

Now the lay has changed. There are many cables and connectors that allow you to connect various devices to the device. The three digital video cables that currently appear are HDMI, DVI and DisplayPort. What are the advantages and disadvantages?


Old video cables, including VGA and Composite video, only transmit analog video signals. Even though it’s good for a CRT monitor but it’s not good for an LCD screen. Even though today many LCD TVs and computer monitors can still accept VGA input, generally LCD TVs and computer monitors work perfectly with DVI or HDMI.

Some video cards and video playback devices including Apple TV, do not even include VGA or composite output, and will become a trend in the future. Even though your computer and monitor now work well with VGA, it never hurts to know which digital cable is best if you want to buy a video device later.


The two main digital connectors used by computers and entertainment systems today are HDMI and DVI. DisplayPort is another new connector that is currently included in a number of new computers, and there are also several mini and micro variants of these three cables

DVI is one of the most common digital video cables on the desktop and LCD monitors today. It resembles a VGA connector, with 24 pins and supporting analogues also video. DVI can stream up to 1920A ~ 1200 HD videos, or with dual-link DVI connectors you can support up to 2560 ~ 1600 pixels. Some DVI cables or ports may have fewer pins because they are designed for low-resolution devices.

So you must pay attention to this. However, if the port contains all the pins, it supports maximum resolution without constraints. The biggest problem with DVI is that, by default, it doesn’t support HDCP encryption, so if your hardware only includes a DVI port, you might not be able to play full HD Blue-ray and other HD content.
