In this article, we’ll tell you everything you need to know for buying that mini projector you’ve wanted for so long.

Here are the crucial aspects of consideration that should determine your purchase of the mini projector of your dreams…

Visual Satisfaction:

This is definitely the highest priority to you if you are looking to project images on a big screen, and there are many factors that work to provide a good image quality. So, read on to know more about them in details:

  • Brightness:

If you are projecting images in a very well-lit area, for example outdoors, then you need a projector that is capable of producing extra bright light. The bright light ensuing from the projector must be able to cut through the brightness of natural ambient light.

So, you need to go for projectors that have a display of a minimum of 250 lumens. That will help you to view the images clearly in outdoor areas.

  • Color Accuracy:

A projector that can render a lot of colors at the same time can give you very color accurate images. Laser projectors usually have low brightness. However, the quality of their hardware beats those of traditional LED (Pico) projectors.

Laser-based projectors, thus, have a higher color accuracy than LED ones. 

  • Resolution:

Resolution basically means detail.

The higher the resolution, the sharper the details. Every projector comes with an in-built resolution, which can either be standard or HD. Low-res projectors can also display HD images, but the problem is that the image gets downsized and appears broken in quality.

However, most LED-based projectors usually have a resolution of 1280 x 800 pixels, which is considerably high and will give you average details if not great. This is a good bargain for the price you usually have to pay for these mini projectors.

  • Keystone Correction:

The most pestering issue with using a projector to set up images is that the image gets crooked on the screen.

The keystone adjustment is, therefore, a vital option when it comes to stabilizing the image. This is the feature that enables you to correct the projection angle and straighten up the image manually so that you don’t have to watch the screen by angling your head uncomfortably.

Having a manual option for keystone adjustment is indeed an advantage.

  • Contrast Ratio:

This feature will help you adjust the darkness or brightness of black and white colors on the screen. An image on a TV screen appears much sharper than an image on a projected screen. The difference is due to the contrast ratio.

The contrast ratio can bridge the disparity between these two experiences and give you a more detailed quality, even with a projector so that you get a complete visual experience.

Basically, a higher contrast ratio will make all the different shades of black and white stand out to you. While a lower contrast ratio will make the images appear flatter by not enhancing the depth of dark and light shifts.

As a rule of thumb, go for projectors that support a minimum contrast ratio of 1500:1.

  • Throw Ratio:

This determines the range of your screen in relation to the capacity of your room.

To find out the throw ratio, divide the distance between the projector and the screen by the width of the projected image itself.

Projectors with smaller throw distances display bigger pictures when closer to the projection screen, while those that have a more prominent throw distance display bigger image when farther away. So, choose your projector by keeping the size of the room in mind.

Auditory Satisfaction:

Mini-projectors often come with a low-powered single audio speaker system. Even though the more expensive models can support higher volumes, unfortunately, the audio quality remains quite subpar. 

The saving grace here is that mini projectors often come with either an audio output of 3.5 mm support or with Bluetooth accessibility.This makes them fit to connect to better external speakers if required.

Now if that seems an extra hassle for you, we should tell you that we think the trouble is well worth it.Since the greater benefit of the mini projector lies in its portability, a compromise on the in-built sound quality is not really a huge setback.

Especially if the mini projector comes with compatible ports for external speakers.


Mini projectors usually only come with HDMI ports. However, some models also come with ports for audio outputs and VGA support.

A USB port and flash memory cards are unlikely in these projectors. But as far as this mini-projector buying guide is concerned, if you are mostly going to use your device in domestic settings, then having an HDMI cable will give you all the connectivity you need.

Other than the wired connections, you will be able to hook up your mini projector to your phone and laptop to make the most of this technology.

Some devices work over wireless networks, while some don’t. So, make sure that you check this out before you finalize the purchase. Easy connectivity can really add to the whole luxurious experience of having a big screen at home.

Battery Life:

The battery is essential for any portable device. This is what will allow you to enjoy the portability of your compact, user-friendly device.

Most of the mini projectors accompany batteries that can run for 2 hours straight, while more expensive models can usually do higher than that if charged fully beforehand.

Remember, the compact size also means that they can’t support heavy, powerful batteries that can give you longer run-times so it will be safer to be near a charging dock while using the projector.


We would like to end this article by saying that you should definitely test the quality of the image if nothing else before buying. This article contains all the necessary pointers you need to make the best of your money and resources.

Therefore, we hope that you will now be able to go out and decide what’s worth your money and what’s not.

So, what are you waiting for? Go and explore, you’re ready!
