Using a laptop to do presentations has become more accessible and more convenient than ever. But you still need a projector to project the screen onto a wall so that your audience can see it. But what about times when you don’t have a projector and have a presentation to make?

There’s a catch here! With the guide below, I intend to teach you how to project laptop screen to wall without a projector in the absence of one.

You can project a laptop screen to the wall using a DIY method. Just follow the instructions described below, and you will find yourself projecting things with your laptop without a primary projector. Mind you, and the method is about creating one projector for yourself.

Things Needed to Project Laptop Screen to a Wall Without a Projector

When it comes to projecting your laptop screen to the wall, any screen size will work just fine. Even a 14 inches laptop will do the job since you’re projecting it to the wall instead of using the screen itself. An affordable 17 inch laptop, on the other hand, will do better if you want a bigger screen upfront, even when not projecting.

Well, in the absence of any projector, you need the following tools.

  • Your laptop
  • Marker or pencil
  • Cutter or blade
  • Large magnifying lens
  • Big paper box
  • Glue
  • Tape

Each of them helps to turn the laptop into the projector, and you should follow the further guides on how to use each of the tools to protect your laptop screen from the wall.

How Project Laptop Screen to Wall Without Projector?

First, if you have to charge the laptop, do that to the fullest and not have any performance issue that causes buzzing since that might hamper the projecting experience. Now, follow the methods below, and you should find it easy to project from laptop to wall without a projector.

How to Project Laptop Screen to Wall Without Projector

Get a Big Cardboard Box

You need a big box to carry out the task as effectively as it should be. You need one that will accommodate your laptop comfortably. You need to place your laptop in it and ensure it sits properly. Mind you, and you need the cardboard to be enclosed as possible.

So, place your laptop at one end of the box, and then you have to work on the direction the screen is facing.

Paint the Cardboard Box

Before you place your laptop in the box, you need to ensure you do all it takes to block out light from the box. So, the best way is to either paint the inside of the box with black paint or use black paper to cover all areas.

Insert the Magnifying Lens

The step of inserting your magnifying lens can be tricky. First, you should get your cutting device or blade to create an opening for the magnifying lens. Next, you should cut so that the magnifying lens will still have some edges on the cardboard to rest on.

Fasten the Magnifying Lens

It can be challenging to keep the magnifying lens in place. So, you should use your tape to keep it in place. Just cut out some part of the tape and use it to secure the lens to the edges of the cardboard.

Rotate the Laptop Screen

If you are using a magnifying lens to project your laptop screen, you need to rotate the laptop’s screen. If you do not rotate it, you will likely see the displayed image upside down. To rotate your screen display, follow the step below.

For Windows 10 users, just search for the app called Video editor. Most times, they come pre-installed, and if not, you have to download the app and install it.

  • Once installed, just launch and follow the steps:
  • Click start a new project
  • Name your project
  • Go ahead to import the presentation you want to project
  • On the video, click place in storyboard
  • Then you can rotate by pressing CTRL + R
  • Then you can go ahead to play the video or save it.

Note: To save yourself the stress, you can go ahead to do this by just pressing the CTRL + ALT + RIGHT, LEFT, UP, and DOWN on the keyboard

Place the Laptop in the Cardboard

Now that you have all set, you should increase the brightness of your laptop to the highest and then place it in the box.

Cover all other parts of the box, seal with the tape, and then direct the box to the wall. You will get to see the screen displayed on the wall. You can switch off the light in the room to see the screen clearly on the wall.

How Do I Flip the Laptop Screen?

So far, it is the simplest thing to do for anyone. You can do this with different methods, and I prefer the keyboard shortcut method.

If you want to flip your laptop screen, just press the following:

  • CTRL + ALT + RIGHT to turn the screen to the right side
  • CTRL + ALT + LEFT to flip the screen to the left side direction
  • CTRL + ALT + UP to flip the screen in the right direction
  • CTRL + ALT + DOWN to flip the screen upside down

Note: A clearer screen will give you a clearer projection, so make sure you’re doing it with a laptop that has a clear screen. If you have a faulty screen, don’t forget to replace the laptop screen.

How to Project Image on Wall From Phone Without Projector?

If you want to project from phone to wall without a projector, you just have to follow the same method as I explained with the laptop above.

Tools you need:

  • Your laptop
  • Marker or pencil
  • Cutter or blade
  • Large magnifying lens
  • Small paper box
  • Glue or Tape

Methods of Projecting to the Wall Using Your Mobile Device.

Use a Shoebox

It is the only difference from the laptop method as you have to use a big box for the laptop. So, using a shoebox for your phone will help with the task. Then, you just need to create an opening at one end of the box to glue in the magnifying lens.

Cut the Box

You need to pick your magnifying lens and place it on the area you want to cut out. Then, make a marking with the marker or pencil, and you can cut it out with a blade.

Glue the Magnifying Lens

Once you have cut the box, you need to insert the magnifying lens into it, and you can keep it in place using your glue. Your glue should help to secure the lens in place.

Position the Phone

You need to position the phone at the other end of the box. But before you do that, you need to increase the box’s brightness to the highest and the volume as well.

You should also ensure the inner part of the box doesn’t have an opening for light to come in. You can cover the inner with black paper for effective projection.

Once you are ready to insert your phone, you can keep it in place using the tape and then close the box with the cover.

You should then see the screen of the phone projecting on the wall. Finally, for the best result, you should shut off all lights in the room.

Safety Tips That You Should Remember

If you want to project your laptop screen or phone on the wall, you need to ensure that you are careful with how you do it. Here are some safety tips:

Safety Tips That You Should Remember

Handle the Laptop with Care

When handling the laptop, you need to do that with care because you do not want to drop the PC on the floor. So, you should handle it with care.

Place on a Flat Surface

When projecting your laptop screen on a wall, present with confidence by placing your laptop on a flat surface instead of placing it on your lap, which would obstruct the screen.

Unplug the PC

It is also advisable that you unplug the pc before you do anything. Ensure that you charge the PC and it is full before you decide to use it in a box to project on the wall. If you don’t have the charger, you can even compensate that and charge laptop with HDMI if your laptop supports that.
