3 things to look for in a new projector.

Presentations can be dry when they’re paper-based, which is why a projector might be exactly what you need to spice up your presence. A projector paints a big picture, gives you a single focal point for your audience to direct their attention to, and can support pictures, video, and sound for a more dynamic experience.

Picking the right projector can be easy, if you keep your needs in mind. Here are the top three things you should look for when you’re getting into a data projector for home or work.

Size and Weight

Weight and size are a two key things to think about when you’re looking at a new projector. Traditional models are a little phonebook-like, square and thick. They great thing is that they tend to have lots of connections, and most of all: they can be less expensive.

Getting into something thinner like the Casio XJ-A235U Portable Projector means you might spend a little more, but it’s easier on your shoulder if you have to carry it around. If you’re installing a projector into a single location, size and weight may not be important, but if you’re carrying it with you, you’ll find that lighter is better!


All projectors generate heat; it’s a by-product of having hot lamps or LEDs that give you great picture quality and rich colours. Heat means the projector needs some form of active cooling to keep it at a reasonable operating temperature, and that means fans.

Bigger fans are, interestingly enough, quieter than smaller fans. They can rotate slower and move the same amount of air as smaller fans that have to move faster–and the faster a fan is, the noisier it is. Look for the operating sound level, it’ll be measure in dB. The lower that number is the better. Decibels are measured logarithmically, so even a small change can mean a drastic difference in volume!

Some smaller projectors will also use heat sinks to vent hot air; this can be a great way of cooling thinner devices without the use of noisy fans.


Projectors are all about light, so the brighter the better. Light is measured in lumens, and this one is easy to understand: the higher the number is, the better. A projector of 2000 lumens or more will give you a usable picture in most conditions, with great results in a darkened room.

LED-based projectors offer brighter picture and more colour depth, so you’ll get more realistic images and crisper text. LED does cost a bit more, but they’re also more energy efficient, cooler, and lighter, making them a great choice for a projection device!
