DVI or Digital Visual Interface was made prior to HDMI (High Density Multimedia Interface), meaning it is an earlier version of a cable. The main purpose of this is to connect the output device (computer) to an LCD monitor or to a digital TV. The DVI can transmit video images only, not capable of transmitting audio. So for better quality video and audio, you need 2 different cables. The HDMI has more tasks to perform. This cable will connect your output devices (computer, game console, Blu-ray DVD player) to a digital television or an LCD monitor. The HDMI cable is capable of transmitting both good quality video and audio. With the more and better functions, the HDMI is preferred over the DVI but – is your computer adaptable to HDMI? High-Definition Multimedia Interface (HDMI) is intended to connect output devices, such as a computer, video game console, Blu-ray DVD player, or satellite or cable box with a video monitor or digital television.

If your output source is only DVI capable, you can pass on the DVI images to the HMDI by using an adapter. Since DVI is designed for computer connection, you would need an audio cable to complete your video viewing. But for HMDI, this is not the case. As HDMI is DVI compatible, you can just connect your ports to the computer monitor. This will not incur any problem.
