How to connect a projector to a computer in 10 steps?

Projectors are usually connected by wire, while there is the possibility of wireless connection. Wireless connectivity is more common with slightly more expensive projectors where you need to use significantly fewer accessories because a connection cable is not necessary.

When it comes to a wired connection, in addition to projectors and laptops, you need a few more important things to connect them properly. Laptop power adapter, projector power adapter, VGA cable, or HDMI cable to connect them.

Some projectors do not have an adequate connection cable in their packaging, so it is important to check that you have all of the above at hand.

After obtaining the appropriate equipment, get ready to discover the answer to the question of how to connect the projector and laptop in 10 steps. And not only that, you will learn how to turn off the projector after use and put it away for the next use.

  • Step 1. – Connect different cables.

How to connect a projector to a laptop? First, connect the computer to the projector using a VGA or HDMI cable. If you have a slightly older laptop or projector connected to a desktop computer, you will have the extra step of screwing two small side screws when combining a VGA cable.

While using an HDMI cable is sufficient to plug the cable into the appropriate port where HDMI is usually clearly written.

After that, first, connect the laptop to the power adapter (battery adapter), and then you can plug in the projector or connect it to its adapter.

  • Step 2. – Start up the projector and laptop.

Now that you have correctly connected the projector and the laptop, you can take the second step. Turn on the projector first using the “Power” button, and then start the computer on the standard power button to follow the projection.

  • Step 3. – Source detection

The projector should automatically detect the input signal and display the image from the laptop after turning on the “Power” button. However, if this does not happen, try pressing the Source Search button on its control panel or the projector’s remote control.

Then synchronize their work using the key combination FN + F8 (function key on which the projector screen icon is visually visible). In some cases, just pressing F8 is enough, so try both options.

  • Step 4. – Positioning the projector.

If you place the projector on a desk, you have to pay special attention to its positioning. There should be one or more feet under the projector itself. You can adjust them manually by raising and lowering the projector so that the image is projected to the desired position.

If you have placed the projector on the office ceiling, you will not have the classic connection of the projector legs, but you will adjust the projector bracket itself. As you will probably use ladders for mounting on the stand, make sure that you must test the projector after you do its positioning and thus avoid additional work.

  • Step 5. – Sound testing

Projectors usually have a built-in speaker, so there should be no additional sound problems. However, if there are any, check whether you have selected the sound source adequately on the laptop through the sound settings. If you’re using laptop speakers, make sure they’re not accidentally turned off.

  • Step 6. – Remove the lens cap.

Projectors usually come with a shielded lens. Therefore, always check the projector cover before use. If there is, remove the lid and set it aside.

  • Step 7. – Sharpen the image.

On projectors, you can focus (focus) or zoom in using the projector dial, usually located above the lens. You can move the wheel left or right in the best direction of the image.

In addition to models that have a manual focus mode, there are newer models where focusing can often be done automatically or by using the appropriate buttons on the remote control.

  • Step 8. – Set the operating mode

When you are done with the previous basic settings, it is time to choose the appropriate mode that will improve the projection effect. Choose the presentation mode, cinema mode or other mode your projector has according to your needs.

  • Step 9. – Final finesse

If you want to fix something extra in the image itself, select the settings that suit you in the menu. The settings you will find in the menu vary from model to model, so we will leave it to you to explore additional possibilities on your own.

  • Step 10. – Turn off the projector

After you finish your presentation or watch the movie, all you have to do is turn off the projector and leave it ready for the next use. But don’t rush to turn off the projector completely. Turn it off via the OFF button, but wait for the equipment to cool before unplugging it.

The most common problems when connecting a projector to a laptop

If you have joined the projector to a computer and the projector still does not display the image, it is possible that you did not do something. In this case, it is necessary to go through the previous connecting process once again to see if you followed all the steps in good order.

We will go through a few common problems that users encounter daily and offer their solutions in the following. If you have additional issues connecting the projector and laptop, it is not a bad idea to go through these common problems with instant solutions.

  • New hardware is not displayed.

If no new hardware is displayed on the laptop, you may need to restart the computer for the computer to try to detect the new device again.

  • The sound is absent.

First, turn up the volume on the remote control or projector. Also, try pressing the audio source button and selecting another audio input. If you use Bluetooth, check to see if the source device is amplified, it often happens to be inadvertently turned off.

  • The remote does not work.

Before making any settings, select the correct source using the Source Search button. Then reduce the distance between the projector and the remote control.

Check that the battery is inserted by the polarities (+/-). Replace the battery if the remote still does not work. And at the very end, don’t forget to turn the remote correctly, directly towards the sensor on the front of the projector.

Projector control panel layout

You will find a control panel with buttons on the projector itself, which you will often use if you have placed the projector on a table or shelf. While if you put the projector on a ceiling mount, the remote control will be more helpful.

To help you master the control settings, we will explain some of the primary buttons that can be found on the projector case.

  • Power Button – is a button to turn on, turn off the projector with a light that usually glows green if the projector is on.
  • Home – the key returns you to the home page if you have previously made some configurations through the menu.
  • Source Search – the button will help you find which sources are connected to the projector.
  • Menu – allows access to various settings.
  • Esc – used to step back in the settings.
  • Navigators – are arrows to navigate through settings.

Of course, the above settings may differ from model to model depending on their additional functions.

Projector remote control


Just as the remote control makes it easier to use the TV, the same is true for the projector. By using the remote control for the projector, you will be able to connect it more easily, manipulate its operation, and at the same time save on steps.

Depending on the projector model, there are different models of remote controls. Specific models contain fewer standard features, while some have them in abundance.

We will explain some of the functions you may find on your projector remote control.

  • Power Button – is a button to turn off and turn on the projector. It is usually separated from the others by another color and is located at the very top of the remote.
  • Source Search – The button allows you to find all sources connected to the projector.
  • Computer – displays the laptop screen.
  • Video – Displays the DVD screen (if connected).
  • USB – displays external devices (if connected).
  • A / V Mute – turns off the picture and sound but not the projector itself.
  • Freeze – pauses the projection.
  • Aspect – changes the aspect ratio from regular to wider.
  • Color mode – updates colors.
  • E-Zoom (+) – zoom button.
  • E-Zoom (-) – zoom out button.
  • Pointer – displays the mouse pointer on the screen. Using the arrows on the remote, you will be able to move the mouse cursor.
  • Volume – adjusts the volume.
  • Menu – offers various settings on the projector.
  • Enter – usually used to confirm the selected menu option.

Although it is seemingly obvious, it should be further mentioned that it remotely uses batteries for power. So if at some point you happen to be remote “not listening” for some reason, check if the batteries need to be replaced.

Connecting the projector to a laptop is not that difficult

The instructions that come with the projector can often be too long to read due to extensive decomposition, which can often cause demotivation when connecting the projector to a laptop.

So we have previously tried to simplify connecting the projector to a laptop in a few steps and explain some basic commands.

We hope that we have succeeded in our mission and that our instructions resulted in the successful connection of the projector with the laptop.
