Projecting from your laptop screen to your wall is not exactly possible without using a projector. However, there is a crude and manual way of doing this. Not that it’s nasty, but it can get better. Why so? The picture quality of this process is not as high-quality as using a projector to project a video or picture.

With the more technological processes, your laptop can serve different purposes for you. By applying the right techniques, you can use your laptop as a monitor for Xbox. Also, you can connect the laptop to projectors without VGA ports.

How to Project Laptop Screen to Wall without Projector. Here is a simplified and cost-effective process on how to project your laptop screen to wall without using a projector. Don’t worry; you don’t need any prior knowledge to get to it by yourself. All you need is some courage focus, and you’ll get the desired results in a jiffy.

How to Project Laptop Screen to Wall without Projector

1. Get All the Equipment Ready

The first thing to do is get all the required equipment to fix up your custom-designed laptop projector. Ensure to keep them all in the right places before you start. You can purchase these tools from Amazon, any e-commerce platform, or even your local stores. Tools like the MagniPros Jumbo Size Magnifying glass and Rust-Oleum 1976502 Painter’s Touch Latex Paint are ideal.

2. Prepare your Box (-es)

The next step in projecting your laptop screen to wall without a projector is to prepare your box. Note that you can do this same thing using your smartphone device. So, for projecting your laptop, you will need a larger box—preferably, a larger cardboard box will do. The box must be large enough to provide some allowances for your laptop to sit in it comfortably.

Also, it should be big enough for you to close the top of the box to prevent light from entering the box from outside. Moreover, the lens you’d be using should tally with the size of your laptop screen. If the screen is equal to your laptop screen, that will do. This will ensure a clear display of your computer’s screen.

Also, it’s good to highlight that projecting with a magnifying glass will flip your laptop screen display the other way. After getting the correct lens for your laptop, you can proceed to the next step.

3. Install the Lens to The Box

This is a critical step requiring you to place the lens in the box accurately. So, we recommend that you get about two or more boxes, just if you ruin the first one. Some of these cardboard boxes are free, so you won’t need to worry about purchasing any.

The first thing to do is to turn your cardboard box on its side, ensuring that the bottom and topsides have a smaller side. Then, place the lens on the cardboard box and mark the edges properly using a pencil on it. Ensure to position the lens on one end of your box so it can resemble a projector’s lens.

After marking lines on the box, take out the lens and cut the box in the markings using a knife. Alternatively, if you don’t have a knife for the job, a razor blade or cardboard box cutter can do. Ensure that the cut is accurate on the box. Then, insert the lens in the box and reinforce it with tape. Once you’ve ensured that the lens is properly fixed, you can now progress with the next step.

4. Insert a Black Paper or Apply Black Paint

To give you the best projection, you need to darken the inner walls of the cardboard box. This will eradicate all probable light refractions and provide you with an ideal image resolution.

Thus, use black matte paint or black paper paint to blacken your box. Using black paint, ensure to paint all sides of the interior, then leave it for some hours to dry completely. Also, you need to cover the lens while you’re painting so as not to stain the lens.

Alternatively, you can blacken the interior of your cardboard box using black paper. Reinforce the black paper by using glue. Also, ensure that you don’t leave any paper loose as it will obstruct the clear projection. Additionally, don’t use tape as it’s reflective and can be challenging when used within your custom-designed projector.

5. Design a Projection Screen

After doing all that, you can now create your projection screen. Get a large white paper or cloth, as this provides you with a clearer screen. Then, position the white paper/cloth screen on the wall at any location you want. Once you do that, support it by using black tape.

Also, ensure that the screen is positioned at a suitable height for your projection.

6. Put Your Laptop in The Box and Enjoy Your Movie

Finally, it’s time to see a movie. Place the laptop in the cardboard projector box. Also, if the laptop doesn’t fit, you can rotate it. Once you’ve got the laptop in the right position, your custom-designed laptop is almost good to go.

However, there’s one more procedure remaining, and that is to modify the video’s direction. If we can recall, we stated earlier that using a magnifying lens will flip the direction of your laptop screen. To solve that, you’d need to flip the laptop’s screen before anything else. This will ensure that the entire display is positioned in the right direction.

Once you’re done setting that up, you can go ahead now and watch movies on your custom-built laptop projector. If you don’t know how to flip your laptop screen, we have outlined how to make that possible in the next section.

How to Flip your Laptop Screen

There are two ways to rotate your laptop screen, and we’d discuss them below. These options include flipping your entire laptop screen or using a video editing software tool.

How to Flip your Laptop Screen

To flip your laptop screen entirely, follow these steps below:

  1. Click on the Windows key on the keyboard or navigate to the Start Menu option. Then navigate to the Control Panel and search for it Control Panel.
  2. Navigate to Display Settings.
  3. Under Advanced Settings, click on the Change Orientation option.
  4. Then, click on landscape orientation (flipped).
  5. For users who aren’t using Windows 10, this procedure is the same in all other Windows versions.

Moreover, using a flipped screen can sometimes be confusing and annoying as you’d need to keep rotating the screen when you want to project and when you want to use it regularly. As an alternative, you can flip the videos you’re watching by using video editing software.

This is a super-easy technique. All you need to do is to launch the video editing software on your computer. Windows 10 comes with native Video Editor software installed in the OS. But if you don’t have a Windows 10 installed on your computer, download video editing software.

When you’ve launched the Video Editor software on your laptop, press CTRL + R to rotate the screen.

Can I Use This Setup to Project Mobile Screen?

This setup won’t work with your mobile screen as it’s too large for the smartphone’s screen. The projector box setup and the magnifying glass that we use for projecting the laptop aren’t ideal for smartphones. So, we suggest that rather than trying to use a smartphone for this kind of setup, custom-design another one for it.

Also, note that the design procedures for building a box projector for your mobile are the same way you built for the laptop projector. So, when you’ve got your tools ready, you can follow the setup process above to build a cardboard box projector for your smartphone.

However, ensure to use a smaller cardboard box and smaller magnifying glass.

Safety Precautions When Doing This

Here are some things you should place at heart while working on creating a cardboard box projector for your laptop below:

  • Don’t allow your kids to come close to your working area.
  • Handle the knife or cutting tool very carefully.
  • While installing the lens, ensure everything is in the right place.
  • Use a suitable cardboard box, big enough to fit the laptop but not too large. Also, ensure that the magnifying lens is not very large.
  • If there’s a need, get the help of a friend or family member.
  • Use matte black color paint and paper.
  • Ensure that your laptop screen is bright enough to provide optimum quality.
  • If you’re painting the interior of your cardboard box rather than using paper, ensure to cover the lens while working.


In this article, we have discussed How To Project Laptop Screen to Wall Without Projector. One very affordable alternative is to design a cardboard projection box. To do this, get all the required tools ready (tape, black paint or paper, measuring tape, knife or cardboard box cutter, magnifying glass, and cardboard). Then, prepare your projection box projection screen, and put the laptop inside the cardboard box.

Also, it’s important to note that, while this is a very effective means of projecting, it’s not the most ideal, and you can not use this same setup with a smartphone. Rather, get a smaller cardboard box and a smaller magnifying screen. With this, you are good to go.
