- Monitors do not receive power through the video signal cable, but instead need their own power connection.
- Compare the back of your computer to the back of your monitor, use the table below to ensure that you connect the correct video cable to the correct video port on the back of your computer and monitor.< >
Laptop Computers: Most Laptop computers have a port on the side or back of the computer to connect an external monitor. You will use this port and the corresponding video cable to connect your Laptop to an external monitor.
Desktop Computers: Look at the back of the computer (Figure 1) to check for any installed add-in video cards. Usually, integrated video cards are automatically disabled when an add-in video card is installed. The monitor must be connected to the add-in video card, if present.

Use only one video signal cable to connect the monitor to the computer. Only one connection is necessary and connecting more than one can cause problems.
Table 1: Video Connections
Display Port is a new digital standard for connecting monitors to computers and has the capability to provide a scalable digital display interface with optional audio and high-definition content protection (HDCP) capability. Display Ports usually resemble USB Ports with one side angled.
A Display Port cable should be used if Display Port connectors are available on both the computer and the monitor.
Digital Video Interface (DVI) is the digital standard for connecting monitors to computers. DVI connections are usually color-coded with white plastic and labels.
DVI cables provide a higher quality signal than VGA cables. A DVI cable should be used if DVI connectors are available on both the computer and the monitor.
Video Graphics Array (VGA) is the analog standard for connecting monitors to computers. VGA connections are commonly color-coded with blue plastic and labels.
A VGA cable should be used if DVI connectors are not available on either the monitor or the computer.
High-Definition Multimedia Interface (HDMI) is the current digital standard for connecting all kinds of video devices.
HDMI cables provide the same quality of video signal as DVI. However HDMI can provide sound through the cable but the Video Card has to support the Audio through HDMI function in order for it to work.
Add-in video cards that use a connector type other than DVI or VGA require a cable adapter, or dongle, to connect to a monitor. Please view your specific service model for more information on adding/removing video cards or refer to the manufacturer of the card for more information about supported adapters.
