Common Ports
Most monitors have at least HDMI and Display ports, but always check before you buy. It’s also worth checking which cables, if any, are included with the monitor.
Multiple Monitors
If you are using multiple monitors it’s a good idea to make sure they are all the same if possible. This is mainly because you get a consistent resolution and brightness across all screens, making it easier on the eye. If you spend a lot of time looking at your screens, you’ll appreciate it over time!
Since many PCs have 1 each of HDMI and Display Port outputs, and monitors tend to come with only 1 cable, there is a good chance if you are getting multiple screens you’ll need to also purchase at least 1 additional cable.
HDMI and Display Port
HDMI ports are pretty common on both PCs and Laptops. They transmit both video and audio so if you output to a screen that has built in speakers, you can use one cable to accommodate both.
Display ports only send video. These are common on desktops, less so on laptops.
The ports look similar, but are easy to identify when you know the difference.
Mini HDMI and Display Port
Both HDMI and Display Port come in a mini version with the same functionality, but with obvious space savings. You can either us a cable with the appropriate connections or an adaptor.
Mini display ports are common in graphics cards supporting multiple monitors, and they usually come with the appropriate adaptors.
VGA and DVI
These are pretty old connectors and much less common these days. Most modern desktops, laptops and monitors do not have them. If you have this as one of your outputs, you will almost certainly need an adaptor to connect to a modern monitor.
