Everything You Need to Know About 4k Projectors

When deciding to buy a 4K projector, there are a number of important issues to consider: don’t forget that there are various models of projectors and that each of them offers various performances. In addition, these tools can come at a very high price.

What Exactly Are 4K Projectors?

A projector is an electronic device which, through light and a system of lenses, projects images onto the surface towards which it is pointed. 4K projectors are tools that offer higher image resolution than Full HD, with approximately 4000 pixels of horizontal resolution.

Advantages and Disadvantages of 4K Projectors

With a 4K projector, it is possible to have a higher image quality on a screen bigger than that of a normal television: in this way you can experience a better immersion. Furthermore, since projectors are light and small instruments, they can be transported to many places.

Obviously, all this is to be added to the fact that, probably, you will need audio equipment and that every now and then you will have to replace the lamps (and they are not very cheap). To know the advantages and disadvantages of these devices, you can refer to this table.


  • Greater immersiveness
  • You can choose to change the screen size
  • They take up less space than televisions
  • Very simple installation and use
  • Possibility to easily transport them from one room to another
  • They are very versatile


  • Occasionally the bulb must be replaced
  • Independent audio equipment must be purchased

Who Should Buy a 4K Projector?

Without a doubt, there are many applications of projectors that make them excellent substitutes for televisions and monitors (for some uses). All this without forgetting their versatility and the excellent image quality they can offer.

They can be used for professional presentations related to graphic design, engineering, or architecture, but also by those who want to have a small cinema in their home.

How to Choose the Best 4K Projector

Unlike FullHD projectors, 4K projectors guarantee a much better video yield, but especially in cheap 4K projectors, the input resolution is unlikely to exceed 1080p: to reach the UltraHD format some technologies are used which, therefore, it is important to evaluate carefully before purchase.


The brightness in 4K projectors is measured in “lumens”, 1 lumen equals the brightness emitted by a candle and the concept is very simple: the higher the value in lumens, the greater the brightness of the 4K projector.

The evaluation of this feature depends very much on the conditions in which you want to use the projector, on the distance at which you will install it from the wall and on the room in which you will use it.

In general, however, these two guidelines can be taken into consideration: if you place the projector in a room that can be completely dark, then you could go towards a model with at least 1500 lumens.

If, on the other hand, you want to use the 4k projector even in a dark environment, then you will need to purchase a model with at least 2500 lumens.


The contrast is another factor to consider because it is precisely the contrast ratio that indicates the performance of the device in the light and dark areas of the projected image.

In essence, it is precisely the contrast ratio that in a 4K projector affects the shades of colors and the depths of blacks: it is indicated with a ratio of


In short, “distance” means the meters within which the 4K projector is able to guarantee an image of the highest quality. It is clear that, given the physical nature of the projection, the greater the distance, the greater the inches of the projected image.

And although it is an important factor to evaluate before buying a 4K projector, one thing must always be kept in mind: cheap 4K projectors are able to project images with a distance of about 3 meters, but our advice is to give more importance to the quality rather than the thumbs of the image.

Keystone Correction

Keystone correction is one of the functions that should not be missing in a 4K projector, not even in economic ones. It is a way in which the projector restores the geometry and proportions of the image and corrects all the distortions due to the position of the device: it is precisely this function that will allow, for example, to position the 4K projector on the ceiling or on the ground. , and still, have a perfectly rectangular projected image.

The Service Life of The Lamp

The lamp life of a 4K projector is measured in hours of use, and opting for a model that does not require continuous replacement could be a cure-all for your pockets.

But considering that practically all current models have a lamp life of over 10,000 hours, it could also take many years until a replacement is needed.


Although it may seem like a small factor, it is essential to evaluate the number of inputs that a 4K projector has. And this is one of the factors that most distinguishes 4K projectors from SD or FullHD ones.

Because if the latter generally have RCA, Cinch or BNC inputs; S-Video input; YUV (Sub DB15 or 3 x RCA / Cinch or 3 x BNC), RGB, RGBs or RGBHV (Sub DB15 or BNC) and DVI, in a 4K projector can not miss the HDMI input, or a DisplayPort and the most modern USB -C: these are the only inputs capable of supporting UltraHD resolution.


Noise is also a very important factor in choosing the best 4K projector. Because it is clear, if you want to relax watching an UltraHD movie on your sofa at home just as if you were at a cinema, it is essential that the projector used is not too loud and does not spoil the atmosphere (and the head).

All 4K projectors integrate a cooling fan, whose noise index is calculated in dB (decibels): our advice is to opt for a model that does not exceed 30 dB of noise.
