If you have a computer with only one VGA port, you can still connect a second monitor. You will need to purchase an adapter, which will allow you to connect the second monitor to the computer. The adapter will plug into the VGA port on the computer and will have two VGA ports on the other end. One of the VGA ports will be for the first monitor and the other VGA port will be for the second monitor. You will need to connect a VGA cable from the second monitor to the second VGA port on the adapter. Once you have done this, you will be able to use both monitors.
There are a few things to keep in mind when using an adapter to connect a second monitor. The first is that the resolution on the second monitor will be lower than the resolution on the first monitor. This is because the adapter is splitting the video signal between the two monitors. The second thing to keep in mind is that the second monitor will only display the same image that is on the first monitor. This means that if you move something on the first monitor, it will also move on the second monitor.
If you want to be able to use each monitor independently, you will need to purchase a video card that has two VGA ports. This will allow you to connect each monitor to a different port on the video card. This will also allow you to set the resolution independently for each monitor.
Connecting a second monitor can be a great way to increase your productivity. It can also be a great way to play games or watch movies on a larger screen. If you have a computer with only one VGA port, you can still connect a second monitor by using an adapter.
