The best 4K projectors: Our suggestions

Buying Guide

Prepare the popcorn, feel comfortable, and relax: our Buying Guide will bring everything you need to know when thinking about buying a 4K projector. Your home cinema will be much more incredible with all the quality that this type of projector offers.

In this Guide you will learn the advantages of a 4k project, its price, where to buy, and also know how to choose the right model for your needs.

What is a 4K projector?

First of all, we need to understand what the 4K projector is about. As its name suggests, a projector is a device that projects images connected to it. This projection can be done on a specific wall or screen for projectors.

Depending on the connectivity of the model, it is possible to project images from your computer, tablet or smartphone, either by wire or wi-fi connection.

But what about the term 4K? What do you mean?

4K indicates the image quality of the projector. One of the most modern on the market, it will transmit these images in Ultra HD definition. 4K technology has four times more pixels than Full HD, and this makes the image sharper, closer to the reality of the human eye.

Is it worth investing in a 4K projector?

If you are a technology enthusiast or just someone who is a movie buff, you have certainly thought about making this purchase. The first determining factor for the purchase is to analyze what the device will be used for. Therefore, consider the following points:

    • Will you use the device for the projection of films or presentations?
    • Do you have a room for projections or plan to use it outdoors?
    • Do you want to use it for home or work?


If you want to use the device for home use or to broadcast movies/programs, a projector with 4K quality will be an excellent purchase option, since in these cases, you can explore the device to the fullest.

In the case of PowerPoint presentations, a simpler model, such as SVGA or XVGA, will probably be enough for your needs. For presentations, the agglomeration of pixels does not influence the experience as much as the lighting control of the environment.

What is the ideal number of lumens for a 4K projector?

It is also worth mentioning that, in relation to the type of environment, for projection in open places, a higher lumen rate is needed, preferably above 4,000 lumens, something commonly found in 4K projectors.

In the case of indoor environments, if the room is small and there is the possibility of turning off the lights, devices of up to 1,000 lumens can meet your need.

In large environments, rates between 2,000 to 4,000 lumens are recommended to ensure the quality of the projection.

What are the advantages and disadvantages of the 4K projector?

The first and biggest advantage is image quality. In this way, you will be able to transform your room into a true cinema.

Another advantage is that most models have a Wi-Fi connection, so you can connect your mobile devices to it wirelessly and project your smartphone, for example, onto a large screen on the wall of the room.

With such incredible advantages, it is even difficult to find negative points. But, the biggest disadvantage is still related to the price of this model. The 4K projector has a high price and is not accessible to everyone. Not to mention that if any part is a problem, this replacement can also be expensive.


Where to buy a 4K projector?

Although increasingly common, the 4K projector market still has few models available. However, there is a growing movement in this market and more and more models are available.

it is possible to find 4K projectors in stores specialized in computer articles, multi-brand stores like such as Amazon.

How much does a 4K projector cost?

4K projectors are expensive devices, which start at R $ 11 thousand, with more advanced models reaching up to R $ 40 thousand.

So it is worth analyzing all the specifications and making sure that the chosen model meets your needs. The ideal is to choose a device that is “made to measure”, that is, no more, no less than you need.

Purchase Criteria: What to analyze before buying a 4K projector?

The process of choosing a projector can be delicate and draining if you don’t know the subject. In some cases, the “the bigger the better” factor can make you buy a device with little functionality for your needs.

After deciding on purchasing a 4K projector, you need to consider some factors such as:

  • Lamp life
  • Number of lumens in the device
  • Brightness type
  • Device connection types

We will detail each of these items so that you can make the best option to buy a 4k projector:

Lamp life

For those who do not have experience with projections, certainly mentioning the projector lamp may seem like an exaggeration.

However, this item directly determines the maintenance costs of your device – something fundamental to be considered in high-cost equipment – and the projection quality. Most models available on the market have lamps with an average useful life of two years in economical projectors.

Depending on the type of lamp, after the half-life it is lost in quality of projection, something that can directly harm the experience.

In the case of 4K projectors, the lamp life tends to be considerably longer, but in case it is necessary to change it, the lamp of this type of device will cost infinitely more than that of an ordinary projector.

Before making the purchase, also research about the lamp and about what the lamp life usually is, as well as its values ​​for exchange.

Number of lumens

Brightness, measured in lumens, is the main indicator of the appliance’s efficiency even in adverse light conditions.

In other words, a projector with a higher lumen rate will perform more efficiently in bright or open environments and will generate sharper images in environments with controlled lighting.

Therefore, before purchasing, it is worth considering the following rule when selecting the perfect model for you: the more lumens, the greater the flexibility of use.

This is true because, if you purchase a model with higher lumen rates, it will even be possible to project it outdoors.

Brightness type

Another factor to be considered when selecting a projector is the type of brightness emitted. By default, the brightness is considered to refer to the intensity rate of the whites, however in some devices the brightness refers to the intensity of the projected colors, including the whites.

This variation between white, black or colored brightness is an important factor, as it can directly influence the contrast and color fidelity. Check this information in the product description before deciding on yours.

Device connection types

To guarantee the quality of the material to be transmitted, it is necessary that the projector has high speed connection means. Most of the projectors have a VGA connection, but it cannot carry out transmissions in higher quality, requiring HDMI 2.0 or HDCP 2.2 ports, which allow high-speed transmission.

There are also models compatible with wireless transmission. If you want to make projections from a tablet or smartphone, it is worth looking for models compatible with this type of technology.

Checking the type of connection, and reflecting what you need most, will save you headaches when putting your 4k projector into operation.
