How to connect two monitors to one computer with one vga port?

If your computer has only one VGA port and you want to connect two monitors, there are a few options you can consider:

  1. Use a VGA splitter: A VGA splitter takes the video signal from a single VGA port and splits it into two, allowing you to connect two monitors. However, both monitors will display the same thing, as the splitter does not increase the video capabilities of the computer.
  2. Use a VGA to DVI adapter: If one of your monitors supports DVI input, you can connect it using a VGA to DVI adapter. This will free up the VGA port for the other monitor.
  3. Use a switchable display adapter: A switchable display adapter allows you to switch between multiple displays, depending on your needs. You can connect the first monitor to the VGA port and the second monitor to the switchable display adapter, which can be connected to the computer through a USB port.
  4. Use a dedicated graphics card: If you need more video outputs, you can install a dedicated graphics card that has multiple VGA, DVI, or HDMI ports. This will give you more flexibility and allow you to connect multiple monitors to your computer.

Note that the options available to you may vary depending on the specifications of your computer and the monitors you want to connect.
