Factors to Consider When Buying 3D Passive Projectors

Buying a 3D projector is trickier than shopping for a regular projector. Some projectors claim to support 3D content, however, it does not work as promised. So, you need to make sure that the projector has the following features before buying

3D Passive Technology

Active and Passive are the two different types of 3D display technologies being used today.

If you are buying a 3D passive projector, make sure the projector has this newer type of 3D technology that uses polarization in both the display and the active shutter glasses to display the 3D effect.

These projectors are hard to find as they require dual projector setups and expensive silver screens.


4K resolution to project 3D content is a huge selling point but not a necessity. If the budget is tight, settle for a 1080p resolution also known as Full HD.

1920x1080p projector with full HD capabilities will display clear, crisp, and well-defined images.


It is important to consider the brightness of the lamp and where it will be installed. Buy a projector with specific ANSI lumens as per the lighting of the area.

For dark rooms, there is no need for a high lumen rating whereas for bright rooms you would need a passive 3D projector with high brightness.

For better 3D projection, buy a projector with 2,500 to 3,000 lumens of brightness.


Along with resolution, sound quality is equally important, especially when viewing movies or videos.

Some of the best 4K 3D projectors come with better, more powerful, crisp audio that blends well with the astonishing video quality.


3D projectors require the use of particular glasses, so, you might want to invest in a projector that has all the right accessories instead of purchasing them separately.

It sounds nice to have all the accessories packaged with the projector, but it is not a common occurrence.

If the projector is not accompanied by the accessories, buy the glasses recommended by the manufacturer.

Lamp Life

You might not want to invest in a projector that stops working after a short time. Go for models with a meaningful lamp life, warranty, and lifetime technical support. Depending on the usage time, select the model with suitable service hours.


Hopefully, you have enough information now to make a great buying decision for a 3D projector. All the aforementioned projectors are from reliable industry heavyweights, so, you can buy one with confidence keeping in mind the personal requirements.
