What is a 4k monitor?

In short it is an ultra definition monitor. The 4k monitor can also be called: ultra high definition monitor, Ultra HD monitor or UHD monitor. It gets its name because it's four times bigger than a traditional high-definition monitor, the so-called Full HD monitors.

Let's explain:

It gets its name because it is four times larger than a traditional high-definition monitor, the so-called Full HD monitors

The high definition standard (Full HD), or 1080p, is an image that is 1,920 pixels wide by 1,080 pixels high. In other words, a Full HD monitor delivers an image with more than two million pixels to the user.

In contrast, Ultra HD, or 4k, offers 3840 pixels wide by 2160 pixels high, totaling more than 8 million pixels of definition.

See the difference in pixels between the different screen resolutions:

  • HD: 1280 x 720 pixels;
  • Full HD: 1920 x 1080 pixels;
  • 2K: 2048 x 1080 pixels;
  • 4K or Ultra HD: 3840 x 2160 pixels;

Can I use my TV as a 4k monitor?

This is a very common question from users. Due to the fact that they are usually cheaper than 4k monitors, many people wonder if it is valid to use a 4k TV as a monitor.

The answer is: it depends. If you already own a 4k TV, it may be interesting to use it as a monitor temporarily. However, it's not worth buying a 4k TV to use it exclusively as a monitor. We'll explain why.

Despite being cheaper, televisions are designed to be seen from a greater distance than someone using a computer, a few centimetres from the eye.

Monitors, on the other hand, are created exclusively to function as a computer display. In other words, they are made to be close to the face. With a higher pixel density, they enable clearer images when viewed up close.

In addition, the monitors have different connections from TVs. This means that the response time when using a mouse is shorter, for example. Milliseconds that are essential for gamers.

Remember: the TV is not designed to be close to the face and this can even cause eye strain

What are the advantages and disadvantages of a 4k monitor?

Get ready for images with surreal quality.

  • Ultra Definition images, four times better than Full HD image
  • New models are increasingly larger, without losing resolution
  • Improved quality of work
  • Increased performance when used in games
  • High value

Why invest in a 4k monitor?

Increasingly sharper images and details that go unnoticed in lower resolutions; Rich colours in detail, delivering an amazing realism. These are some of the reasons to invest in a 4k monitor, especially if you work with video or photo editing.

With more pixels within a given area, you get a screen with more clarity, vividness and sharpness. It's worth looking for models that have an Eye Saver Mode function, which reduces the emission of blue lights, providing greater comfort for your eyes.

What settings should my computer have in order to use a 4k monitor?

The latest computers with integrated cards from Intel or AMD support the resolution when running Windows 10.

However, when we're talking about any other heavier software, whether it's editing videos in 4k, or Ultra Definition gaming, for example, a more robust video card will likely be required.

Also, your processor and RAM should be of high quality.

Don't forget to check your computer settings. The 4k monitor will only work in its entirety, if your PC has enough graphics performance to run more than eight million pixels on the screen

Purchase criteria: What to take into account when choosing your 4k monitor

You are looking for a top-notch product. Therefore, it is of utmost importance that you know all the details of an ideal 4k monitor before choosing one.

To help you out, we've prepared a list of the main features to keep in mind when buying. Check it out!

Resolution and size

As your search will be for 4k monitors, their size will not interfere with the resolution. Therefore, the bigger the better. In that case they will all come with the 3840 x 2160 pixels configuration. However, the bigger, the more expensive too.

The models most commonly found on the market range from 15 to 29 inches. It's up to you to decide which one suits you and your pocket best. Before buying, remember to measure the space where you will put it. That way you won't be surprised when the purchase arrives.

Work, gaming or just surfing the internet? Having that goal well defined is essential when choosing your ideal 4k monitor.

Using it for gaming or editing 4k videos and Ultra Definition photos will be a differentiator for you. However, it is worth thinking if your current goal is just to browse the internet or perform activities that do not demand so much from the monitor.


Don't buy your 4K monitor before checking what inputs it has. An average monitor will offer at least one HDMI, USB and DVI input.

Once again we reinforce that you should be careful about your computer's settings. You need to check if your video card and input are compatible with the monitor.

The more inputs the monitor offers, the more expensive it will be.

Refresh rate

Roughly speaking, the refresh rate of a monitor is the speed at which the image is passed to it. The more the image refreshes, the smoother it looks before the eyes. So the idea is to look for monitors with a fast refresh rate. This number is measured in hertz (Hz).

The more the image refreshes, the smoother it looks to the eye

While televisions are generally 60Hz, there are monitors that can go up to 244Hz. The choice will be based on your goal. If you're looking for a gaming monitor, the higher the Hz rate, the better. If you're looking to work, a monitor with 60 or 120Hz will do the trick.


Stunning images, far more detailed gaming and better edited videos. These are just some of the benefits that a 4k monitor can bring you.

As we've talked about throughout the article, it's important to check that your computer will be able to deliver all the pixels of Ultra HD resolution.

If the answer is positive and you really need more than 8 million pixels of definition, we wish you good luck in choosing your ideal 4k monitor!
