Type of 3D ProjectorsType of 3D Projectors

There are two types of 3D projectors: active and passive. Active projectors require the use of a 3D TV or Blu-ray player to function, while passive projectors don’t. Both have their benefits and drawbacks.

What is Active Projector

Active 3D projectors require a 3D TV or Blu-ray player with an HDMI port.

Active projectors have the advantage of being able to give the best quality in terms of color, contrast, and brightness. An active projector also has an infinite off/on cycle so it’s possible to use them for long periods of time without worrying about damaging the lamp. Active projectors are able to deliver a high refresh rate which means they are perfect for gaming and watching fast-paced films. Active projectors don’t require glasses so you can view them from any angle even if you’re sitting in front or behind someone else who is viewing it.

What is Passive Projector

Passive projectors don’t require a 3D TV or Blu-ray player to work as they don’t have an HDMI port. Passive projectors are ideal for presentations and giving people the opportunity to view the image from different angles.

One of the downsides is that passive projectors are dimmer than active ones, and it can be hard to see them in the dark. Additionally, glass cleaner is needed as passive projectors emit more heat due to their low lumen output.

Passive 3d projectors also come with a dimmer contrast ratio and brightness which limits their use in home theaters. There is also no off/on cycle so it only works if you’re plugged into the power supply which means that they need more maintenance and care.

Passive 3D projectors do not come with a remote but you can get an IR extender which makes it possible to control the projector from a distance even if you don’t have access to the remote.

Advantages of Passive Projectors

  • A cheaper option
  • Convenient to use
  • Can be used from any angle by sitting in front or behind the projector

Disadvantages of Passive Projectors

  • Dimmer image quality compared to active projectors
  • Glass cleaner is needed and can be messy. If you are planning on buying a passive 3D projector, you will need a glass cleaner which can be messy and annoying.
  • Requires more maintenance as it requires cleanings even if it’s just the filter depending on the type of lamp used.

Type of 3D Projectors


There are pros and cons to both active and passive 3D projectors, but for most users, the benefit of a passive 3D projector is that it gives the viewer the ultimate flexibility.

If you want to enjoy a great movie without the hassle of finding old DVDs or Blu-rays or having to make sure your TV is compatible with 3D, then a passive 3D projector is a great option. Passive projectors don’t require an HDMI port so they are perfect for all types of media devices such as computers and smartphones. They also tend to be cheaper than active ones as they don’t need any additional hardware.

We hope our list of the top 3 best passive 3D projectors will help you decide on which passive 3D projector is right for you.
