How to Connect a Laptop to a Projector

Are you in a bind and need to figure out how to project your laptop screen to a large group of people? Read on. As long as you have access to a projector, you’ll be in good shape. This ementes teaches you how to connect a laptop to a projector using an HDMI, DVI, VGA cable, or Bluetooth (if both devices are compatible with Bluetooth).

Method 1 Using a Cable with Windows 10

1. The cable should be connected to the appropriate port on both your laptop and the projector. Following the identification of the cable (HDMI, DVI, or VGA), the two ports can be connected together. Many video connection ports may be labelled; however, if they are not, look at the shape of the cable and plug it into a port that looks the same as the one you are trying to connect to.

The VGA ports on a laptop are the most common type of output port on a computer. These have the appearance of ports, with three rows of five holes on each side. If your laptop does not have a VGA port, it should at the very least have an HDMI port on it. You may need to purchase a VGA or HDMI adapter from an electronics retailer if your laptop does not have either of these features built in.

Some Windows computers are equipped with Miracast functionality; if your projector is equipped with this feature, you will not be required to use any cables. To check if your Windows laptop is compatible with Miracast, look for and open the Connect application.

2. Start by turning on your projector (and laptop, if needed). To proceed, you must have both your laptop and the projector turned on.

3. Press ⊞ Win+P and select a sharing option. On your monitor, you will see a list of screen-sharing options, such as:

PC Screen Only: By selecting this option, the projection screen is turned off and your laptop screen is not shared with others.

The image on the projector will be the same as the image on your laptop screen if you duplicate it.

If you choose this option, the projector will be treated as an extension of your laptop’s screen, giving you more space. However, if you choose this option, you will have to drag anything you want to share from your laptop’s screen to the projection area.

Only on the second screen: You can share everything from your screen to the projector, but you will not be able to see anything on the display screen of your laptop.

Method 2 Using Bluetooth with Windows 10

1. Start by turning on your projector (and laptop, if needed). In order to proceed, you’ll need to turn on both the projector’s screen and your laptop.

2. Pairing Mode should be selected on the projector. Turning Bluetooth on and making it discoverable and pairable is usually accomplished by pressing a button on the projector (or the remote that came with it), but you should refer to the projector’s instruction manual for additional information.

3. Connect your laptop to the project’s network. More information on the Bluetooth pairing process can be found in the article How to Connect a PC to Bluetooth. Most of the time, you’ll go to the Bluetooth connection centre in your taskbar and select the projector as the device to connect with.

When you first connect to the projector, you may be asked to confirm a series of numbers or a passcode. If this is the case, proceed.

4. Press the Windows key and the P key at the same time. On your monitor, you will see a list of screen-sharing options, such as:

Only on a computer screen: When you select this option, the projection screen is turned off, so that your laptop screen is not shared.

The image on the projector will be the same as the image on your laptop screen if you duplicate it.

If you choose this option, the projector will be treated as an extension of your laptop’s screen, giving you more space. However, if you choose this option, you will have to drag anything you want to share from your laptop’s screen to the projection area.

Only on the second screen: You can share everything from your screen to the projector, but you will not be able to see anything on the display screen of your laptop.

Method 3 Using Cables on Mac

1. Connect the cable to a port on both your Mac and the projector, and then turn on the computer. You can connect the two devices after determining which cable type to use (HDMI, DVI, or VGA). Many video connection ports will be labelled; however, if they are not, look at the shape of the cable and plug it into a port that has the same shape as the cable.

The VGA ports on a laptop are the most common type of output port on a computer. These have the appearance of ports, with three rows of five holes on each side. If your laptop does not have a VGA port, it should at the very least have an HDMI port on it. You may need to purchase a VGA or HDMI adapter from an electronics retailer if your laptop does not have either of these features built in.

If your Mac does not have any ports, you can purchase an adapter that will allow you to connect a VGA or HDMI monitor to your Thunderbolt port.

2. To access the Apple logo, select it from the drop-down menu. On the left-hand side of the menu bar that runs horizontally across the top of your screen, you’ll find this option.

If your Mac automatically detects and projects your laptop screen to the projector, you do not need to proceed with this method.

3. Click System Preferences. This is generally the second or third listing in the menu.

4. Select Displays from the drop-down menu. This is typically found in the second row of icons on a display screen, next to an icon for the clock.

5. Select the Arrangement tab from the drop-down menu. This is located at the very top of the window, next to the words General and Color.

You can either drag and drop the display screens that have been highlighted, or you can check the box next to “Mirror Displays” to have the same thing displayed on both your laptop and the projector simultaneously.
