Once you’ve gone through the task of learning how to install your projector, you might be wondering how you can connect different devices so that you can start streaming media. The vast majority of modern projectors make it easy to learn how to use a projector, even if you’ve never used one before. All you’ll need is the right connectivity cables, a streaming device, the base unit, and this easy-to-follow guide.

Connecting a Laptop to a Projector

The most common device you’re likely to use with your projector is your laptop, and getting it set up is far easier than you’d think, especially if you have a wirelessly enabled projector.


With a wireless-enabled projector, you’ll be able to connect your laptop via the internet. Both devices will have to be on the same network in order for the media to go from one device to the other. Wireless connectivity gives you the option of avoiding unsightly cords, and you can move the projector from one room to another with ease.


In most cases, people will rely on a wired connection when learning how to use a projector, as it’s more affordable than wireless. In this case, you’re going to need access to either an HDMI cable or a VGA cable.

Connect the cable to your laptop and then connect the other end to the projector. This will allow you to choose from a selection of media that you might be interested in displaying.

Depending on the settings for your laptop, you may need to open your audio or video settings to adjust whether sound will come out of your laptop or the projector. In terms of display settings, you’ll want to manage those through the projector’s menu with the help of your remote.

Connecting a Console to a Projector

The second most common device you might wind up using when learning how to use a projector is a video game console, especially if you have a Netflix account and if you enjoy playing games. Similar to connecting your laptop, the process is simple.

Step 1: Connect the console to the projector

The first step you’ll have to take is to figure out how you want to connect your device to the projector. For the highest quality graphics and sound transmission, it’s recommended that you use HDMI. All you have to do is connect the HDMI cable from your console to the projector to complete the first step of installation.

Step 2: Connect audio devices

Depending on how you’d like to listen to the audio provided by the game system, you can either choose between using headphones, listening through the projector, or having high-quality audio through a sound system. Headphones are simple enough, as all you have to do is plug them into your controller, and listening through the projector can be managed by visiting the audio settings on your console and selecting the right audio output option.

If you want the highest quality audio possible, it’s recommended that you invest in an AV receiver. With the AV receiver, you’re going to want to run the HDMI from the console to the receiver and then connect a second HDMI cable from the receiver to the projector.

Connecting a Cable Box to a Projector

The third most common device you’re likely to use with your projector is a cable box, and setting them up together is equally as easy as the previous two devices.

Step 1: Connect the cable box to the projector

First, you’re going to want to connect an HDMI cable to the “HDMI Out” port on your cable box and then connect the cable directly to the “HDMI In” port on your projector.

Step 2: Change video settings

Unless you have a projector that automatically detects the port that is in use, you’re going to need to navigate through your menu settings in order to select “HDMI” as the “Video Input.” At this point, you should easily be able to adjust any video settings such as brightness and contrast for the best possible picture quality.

Connecting a Smart Device to a Projector

If you’re someone who doesn’t have a laptop or cable box, but you have smart devices where you normally watch your favorite TV shows and movies, with most projectors, you can also stream media from smart devices such as your phone.

Option 1: Connecting via applications

The first option that you might have if you have a wirelessly enabled projector is to download a streaming app on your smartphone or tablet that allows you to stream media from one device to another. Depending on the type of projector you buy, they may have a dedicated app that will enable you to stream to your device; otherwise, you’ll have to find a third-party developer.

Projector apps are easy to use as they give you step-by-step instructions on how to set your device up with your projector.

Option 2: Connecting via cables

The second option that you have is to connect to your projector with the help of cables, and as every projector has hardwired inputs, this works for all models on the market. To connect via cables, you will have to purchase either an HDMI or MHL adapter to allow you to use a cable from your projector to your smartphone or tablet.

Once you have the right equipment, you can connect to your projector by following the same steps for your laptop and/or cable box.

Option 3: Connect via Chromecast

Arguably the easiest way to get media from your smartphone to your projector is to use Chromecast which comes with a built-in projector-to-phone connector that nearly every single smart device can use with ease. It will surely get rid of most of the hassle and allow you to stream within a matter of minutes.


One of the largest selling points for projectors is that they enable you to watch different types of media from an array of electronic devices ranging from laptops to smartphones. With the help of this guide, you’ll be able to use your projector to its fullest potential for the most comfortable and user-friendly viewing experience possible.
