Do 3D Projectors Need A Special Screen? Honest Answer

In this article, I will tell you do 3D projectors need a special screen, how a 3D projector work, and how to invest in a special screen.

The advancement in technology has also exceeded the demand for 3D projectors. It is becoming highly popular with exponential growth in variety.

However, when it comes to deciding about buying a 3D projector, a question might pop into your head: do you need to buy a special screen for my 3D projector?

The prediction of purchasing a special screen might be perplexing, but fortunately, you can watch your favorite 3D content on a pre-existing screen.

If you are confused about the quality of content and features of a special screen, this post will provide all relevant knowledge about whether 3D projectors require a special screen.

Does Your 3D Projector Need a Special Screen?

Do 3D Projectors Need A Special Screen

A 3D projector doesnít need a special screen if you want to view content through it. You can still watch 3D content without any screen, but the compromised quality will force you to make the final decision.

To view standard 3D content through the projector, you will need to buy a screen with high gain in place of a regular screen. Gain is the quantity of light reflected by the screen in contrast to the uniform surface used as reference.

This screen will enhance the picture’s overall brightness by reflecting the light in a direction.

How Do 3D Projectors Work?

You may likely recall the time when you and your family used to visit the IMAX Theater to enjoy the 3D experience.

You might have never imagined experiencing the same environment inside your home. However, now 3D projectors with extraordinary picture quality are easily found.

A 3D projector has varying formats, including:

  • Frame-Packing
  • Side-by-side
  • Top-and-bottom 3D signals.

These formats integrate dual images to be elucidated by the left and right eyes. With the help of 3D glasses, it is possible to view explicit 3D content projected on the screen.

The common misconception developed among people when they considered the projected image displayed on the screen completely differs from a standard projection; they thought buying a special screen is compulsory for 3D.

However, with more advanced innovations, 3D projection is possible to be done with the help of active/passive 3D glasses. So, your family and friends can remember the old time spent at IMAX at home by just using 3D glasses.

Luckily, the glasses donít cost much, and you wonít be spending too much to enjoy 3D movies on your comfortable couch.

When Do 3D Projectors Require Special Screens

If you have installed a dual 3D projector, you will need to invest in a polarized screen. Two lenses are used to project images in dual 3D projectors that can be seen through both your eyes.

The 3D viewing experience will be more enjoyable with dual projections, which you canít gain with only glasses.

Remember that you will only need a polarized screen if you are using a dual 3D projector that displays images from two different lenses instead of projected from 3D signals composed to be detected by lenses.

This will happen if you have a passive 3D projector, which will require a polarized screen and lens to preserve 3D pictures.

Even though you are watching on a polarized screen, you will still need to use 3D glasses to differentiate between the available options clearly. However, most people prefer using an active 3D lens to eradicate the need to buy a special screen.

Is it Possible to intensify 3D Effects Using a Special Screen?

If you already have special glasses to view 3D content, there is no need to purchase a special screen. Even in high-quality 3D projectors, you can solely rely on glasses. However, in Ambient Light Rejecting screens, you can get more reflective screens that deliver an extra gain.

This kind of screen is also best for brightening pictures as 3D images sometimes get darker. This happens due to different formats that are already mentioned above.

What to Look For If You Plan to Invest in Special Screen

You have got a clear idea about when you should invest in a special screen and when you shouldnít. However, if you ever plan to spend money on buying a special screen, you must be aware of some factors that can prove helpful while making a decision.

The Material of Screen:


People usually consider the requirement of a single white-colored screen to project 3D images, but the screens arenít limited to just one option. Plenty of choices are available in the market, varying in color, design, gain, and several other features to make an accurate decision.

  • A white-colored screen is ideal for a room with less ambient light. Screens are also present in gray, black, and silver.
  • By increasing the light intensity inside the room, you will lose the clarity of the image, and it will become hard to view the content. While gray, black, and silver screens prove beneficial in discarding excessive light to enhance the image clarity without darkening anything.
  • To check out the gain, you must estimate it properly. If the gain is lower, it will help display a crisp image in a dark environment.
  • The image will become brighter through the center and darker at the edges if the gain is higher.

Screen Size:


The size of the screen should align with the intended image size. We recommend getting a screen that displays the largest image for your projector if, at any point, you want to increase the projection size.

The wall size and throw distance also matter. So, first, measure the area and then plan on getting a screen according to the space requirements.

Considering the height of the ceiling will also aid in getting the best image quality results.

Aspect Ratio:

Each projector has a specified aspect ratio which must be selected properly. Usually, two aspect ratios are considered most, 16 ? 9 or 2: 4: 1.

  • 16 ? 9 is the ideal ratio for watching sports, games, TV shows, and similar content.
  • While 2: 4: 1 is the best to project movies.

Screen Modes:

Screens can be found in a variety of modes or styles, including:

  • Fixed screens that are permanently kept in the same place. They are installed once and hold their position for a long time without any worries. The other benefits of these screens are lower prices, and they require less power.
  • The Retractable screens are functional for more than one room. This screen looks very attractive and remains flat when extended.

Final Thoughts

We hope this guide will prove helpful for you when deciding whether to buy a special screen for your 3D projector or not.
