How To Project Laptop Screen To Wall Without Projector

Many of you might be interested in knowing how to project image on wall from laptop. So let’s start with the processor instructions to make your DIY projector. Here are the steps:

1. Right Size Of The Box

One of the most crucial steps in creating a projector is finding a cardboard box of the correct size. Otherwise, it can be challenging to adjust the image later on the bigger screen. So always get the appropriate box which should be large enough to place the laptop.

You should have space for moving the laptop screen inside the box, and there should be no holes in the corners. Otherwise, the light entering the box will ruin the picture quality on the screen entirely.

2. Choose The Right Size Of The Lens

Buy a magnifying glass similar to the size of the laptop to convert pictures accurately from a laptop to the wall. If you have the right lens size, move to the next step.

3. Install The Lens Correctly

Now, before installing the lens, if this is the first time, we suggest you keep an extra cardboard box in your home if you ruin the box. Take the marker or pencil and adequately measure the lens on one end of the box.

After taking measurements of the lens, cut the size of the lens from the box precisely so that you can secure the place of the lens. Use a knife and cutter to make the proper cutting on the box. Now insert the lens and secure it correctly by using the double-sided tapes so that it will not leave its place.

4. Cover The Box With Black Paper

To reduce any extra refraction of light, you need to convert the box’s interior with black paper or use black paint to apply it to the wall of the box. Don’t cover the lens with paint. Now let the container sit for a few hours to dry the paint thoroughly.

5. Place Laptop Inside The Box

Coming to the final step, now we have to keep the laptop inside the box so that it can sit in the proper spot. Adjust the lens and screen distance to get exact larger screen pictures on the wall.
