Should I replace my monitor when buying a new computer?
If you plan on not using or selling your old computer and have an extra monitor, the older monitor can almost always be used on a newer computer. To clarify if it can be used, verify that the connector type for the monitor matches that on the back of the new computer.
The most common types of monitor cables and connections are VGA, HDMI, and DVI. Most older computers will use a VGA style connector and most newer computers and video cards will use an HDMI cable. If you have an older VGA monitor that you want to work with HDMI a VGA to HDMI converter can be used.
Connecting a PC monitor to an Apple computer
You may experience issues when using a PC monitor on an Apple Macintosh. However, an Apple cable converter can be purchased to resolve this issue. This cable converter can be purchased through the monitor manufacturer or through Apple.
Not all Apple monitors will work on non-Apple computers.
