The “how to project mobile screen on wall without projector” is a question that has been asked many times. The best way to do this is by using an external monitor with the projector connected, or by using a wireless keyboard and mouse.

How To Project Laptop Screen To Wall Without Projector?

Investing in a new projector to display stuff on the wall from your laptop may not be the most cost-effective choice. For professional use cases and business presentations, dedicated projectors are ideal, but for everyday usage, your wall will suffice.

Although projecting your laptop’s screen to your wall seems to be a simple process, it requires some planning. It’s also possible that you won’t do it perfect the first time, so you’ll need to practice a lot to get the feel of it.

Here’s how you project the screen of your laptop onto a wall without using a projector. We also have some tips if you ever need to project your phone’s screen.

What are the requirements for projecting a laptop screen to a wall without using a projector?

Some tools are required for the process to be successful before attempting to project your laptop screen on a wall without a projector. Almost all of these instruments are typical household items, and any that you don’t have on hand can be purchased at any convenience shop in your area.

Here are the items you’ll need to start projecting your laptop screen to a wall without using a projector.

  • Laptop.
  • Pencil.
  • Tape.
  • Smartphone.
  • Knife with extreme precision.
  • A magnifying lens with a significant magnification power.
  • Paper made of cardboard.
  • Matte black paper
  • Glue stick is a kind of glue.

Another advantage of most of these materials is that they may be improvised using comparable equipment. In the case of matte paper, for example, any thick black paper will suffice. If you don’t have access to precise knives, you can use scissors.

You must use care while improvising on any material. Scissors don’t cut as smoothly as a precise knife, and cutting unevenly might ruin the whole operation.

Before you get started, keep in mind that this isn’t going to be a complicated project. So pay attention, calm your thoughts, and use your imagination to come up with a cost-effective alternative projector to watch your favorite movies with. The steps to make it work are outlined in the next section.

Without a projector, how can you project a laptop screen onto a wall? (Step-By-Step)


Step 1: Select the Appropriate Box and Mirror

The first step is to double-check that you have the appropriate box and mirror for the job. The box you’re using should be big enough to hold your laptop but not too huge so that things don’t become too complicated.

It should include a light source to line the inside of the box so that light may pass through the magnifying glass. For a brighter and higher-quality image, choose a light source with intense beams.

To make it easy to change the focus, make sure you choose the suitable box size and maintain a safe distance between your laptop and the setup.

It’s also a good idea to use a lens that’s the same size as the device you’re using (your laptop in this case). You’ll need your pencil now because you’ll need to note the size of your lens on the box’s thin side. Tracing the lens will allow you to accomplish this more precisely.


Step 2.) To Improve Image Quality, Blackout The Interior

The next step is to cut the box open from a single corner using your precision knife. Be cautious while cutting so that you don’t wind up ruining the box.

Cover the inside of the box with the black matte paper you gave previously, using glue for support. If black matte paper is not available, as previously indicated, you may use any thick black paper.

The purpose of covering the inside of the box with paper is to prevent light reflection and create a complete blackout, directly increasing picture quality.

Painting all neighboring surfaces of the inside with back-colored paint should suffice if the concept of covering the interior with thick black paper bores you. Paint, on the other hand, is difficult to clean and does not perform well.

Installing Your Lens Into The DIY Mobile Projector (Step 3)

It shouldn’t be difficult to put your lens inside the box; all you have to do is be cautious and follow the directions exactly. To get a better outcome, cut the pencil mark you produced in step one open and attempt to make it the same size as your lens.

The lens may then be inserted into the hole. Make sure you don’t damage the box in the process, since this would force you to repeat the whole job, which is why you should invest in the finest equipment.

Step 4.) Create a manual, focus-adjustable phone projector

To fit inside your first box, you’ll need to create a second one. This allows you to control the focus and move the lens using your phone. To increase stability, place the second box within the first.

Make tiny slits along one side of the box and fold the flaps, then use your glue to attach the adjacent flaps and glue the lens to the inner box flaps. The box should be stiffer as a result of this. You may also use the ruler you received before to achieve accurate measurements.

Install the Mirror in the Cardboard Phone Projector (Step 5)

The picture on your phone will now be upside down and in an unsettling left-to-right orientation. This will result in an unmanageable projection experience, but there is a surprisingly simple cure.

You may need to stop the auto-rotate feature on an iPhone, but your Android phone should be good. To keep the phone head-down, flip it over and put the picture at a 45-degree angle on the edge opposite the lens.

Create A Window For The Phone (Step 6)

After carefully measuring your phone screen, use your pencil to draw a rectangle on the projector’s cover right above the mirror. With your precise knife, remove the cut.

You’ll see that the picture from your projector is correct but excruciatingly little at this stage. Fit the magnifying glass into the gap you’ve just created, and you’ll have a professional-level projector for all your purposes.

Getting Your Phone Set Up

If you are unable to complete the steps above, your smartphone may need further configuration in order to function with your projector.

Because iOS includes a rotation pattern that allows it to spin all the way around, you’re significantly more likely to have issues with an iPhone. You may have to rummage into your settings to switch off this behavior in order to get your projector to function.

Some Android applications also have strange rotation issues. Whether you download an app that rotates automatically when you spin your phone, go into the settings to see if there’s a way to change it.

Without a dedicated speaker, sound quality for projection might vary from non-existent to extremely bad. If you’re concerned about the sound quality of the projection, connect your phone to some Bluetooth speakers ahead of time.

You should look beyond your phone’s microphone if you want your voice to complement the projection. A inexpensive wireless microphone from an internet retailer should solve any issues you have with your microphone, resulting in a near-perfect presentation.

It’s not difficult to set up your device for your DIY projectors. Even if you aren’t working on a DIY projector, the majority of the external components required are necessary.

Image Image Quality

It’s important to realize that the DIY projector isn’t the genuine deal. As a result, you can anticipate all of the functionality of a normal projector. The picture quality is one flaw you’re most likely to notice.

Because of the disproportionate magnification, there may be some blurriness in the picture. You may improve the visual quality by shrinking the size of the image on the wall.

What Is The Best Way To Project An Image On A Wall Using A Flashlight?

Using a flashlight and a Fresnel lens, you can project pictures on a wall. To use your flashlight as a magnification, just aim it towards a wall and utilize the magnifying glass you already have.

Direct the flashlight towards the targeted topic while turning the lamp on, and the image on the wall should have the opposite effect.

To achieve the precise picture and viewpoint you desire, try directing the lens a bit differently. Don’t worry if you don’t get it right away. Just keep trying, and with practice, you’ll become better.
