A 4K monitor gives you an impressive resolution four times higher than a full HD display. This is also referred to as a UHD monitor or Ultra HD monitor. This new screen generation is particularly popular with passionate gamblers because playing with a 4K gaming monitor makes playing even more fun. But also for the image processing, graphics programs, and normal everyday applications worth such an acquisition.

Top 10 4K Monitors

4K monitor – what is it?

Not everyone can directly relate to the term 4K monitor. For this reason, we would like to take a closer look at this and explain to you. what is behind the name and what a 4K monitor, which is often referred to as a UHD monitor or Ultra HD monitor, is characterized.

“4K” comes from English and is a popular abbreviation for “4000”. So the letter “K” replaces the zeroes – that’s the same with “2K”, which stands for “2000”. The number 4000 refers to the resolution of a 4K monitor, which is usually 3840 pixels wide in these screens. The exact number is rounded up slightly. For some monitors, however, they are also 4096 x 2560 pixels, but they also count as 4K monitors.

Compared to a Full HD monitor, also referred to as a 2K monitor, the 4K monitor brings a four times higher resolution. Even more striking is the difference when comparing UHD / 4K with other resolutions like SD or HD Ready. The picture quality at 4K is noticeably better, the contrast is razor-sharp. Whether gambling, watching TV or working – switching to a 4K monitor pays off in many ways for you.

Why a 4K monitor?

You may be wondering why you should opt for just such a screen. “When is a 4K monitor worthwhile?” Could be such a question. For this reason, we have compiled the most important arguments for you and listed them in a clear form below:

  1. Noticeably higher resolution than Full HD or SD
  2. This significantly sharper picture
  3. Ideal for gaming and movie enjoyment
  4. More space and overview on the desktop thanks to the high pixel density

In that sense, the purchase of a 4K monitor is basically worthwhile for everyone. Whether you use the device as a 4K gaming monitor, watch the latest Hollywood blockbusters or work on it – the benefits are obvious. So it pays off, especially when working, that the devices have such a high resolution. Because even very small fonts are displayed razor-sharp on the 4K display . In the end, more content will fit on the screen, since scaling is not necessary.

What advantages and disadvantages does a 4K monitor have?

In order to be able to make a purchase decision in a genuinely sound manner, it is always helpful to deliberately contrast the advantages and disadvantages of a product. So we would like to keep it synonymous with the theme 4K monitor. Clearly arranged in “Pro” and “Contra” we have listed the arguments for or against the acquisition of such a screen for you.

4K monitor – what to look for when buying?

Before you buy a 4K monitor, you should first think about it. The crucial question is: For what purpose do you want to purchase the device first? Because, after all, very different aspects are important, depending on whether you want to use the screen mainly for gambling or image editing or web design. Of course, there are always a few basic things to look out for when buying. We have compiled these for you below:

  • How is the picture quality ordered? Which panel technique is used? For example, IPS panels stand for particularly strong and natural-looking colors.
  • What is the maximum brightness of the 4K monitor? This point is especially important if the display will be partially exposed to direct sunlight.
  • How big should your screen be? The bandwidth ranges from 24 inches to 43 inches – a larger 4K screen is more expensive but offers more options.
  • How short is the reaction time? Especially with action games like shooters, it should be as low as possible.
  • Which connections are available? Apart from HDMI, DisplayPort is also almost standard today.
  • What are the values in terms of contrast, brightness and color depth?
  • What refresh rate does the device have?
  • Does the 4K monitor have a picture in picture function?
  • Are there any technologies that reduce screen flicker?
  • Does the device have built-in speakers?
  • Is the screen height adjustable, tiltable and tiltable?
  • Should the display be dull or glossy?
  • What is the power consumption of the monitor?
  • Which accessories are included?

Ultimately, the 4K monitor of your choice should also convince you in terms of appearance and processing. And the price-performance ratio could certainly decide in the end to decide on this or that device.

Which manufacturers are leaders?

Various manufacturers have positioned themselves in the market for PC screens. So if you want to buy a high-quality 4K monitor today, you have a lot of choices in brands and models. We have listed some of the leading manufacturers for you:

  • Asus
  • AOC
  • BenQ
  • Dell
  • HP
  • LG
  • Samsung
  • Philips

Far more important than the brand are, of course, completely different criteria such as the image quality, the equipment and above all the intended use. we present a current selection of recommendable models – maybe your future 4K monitor is also included?

4K monitor – what is the perfect size?

Whether 24 inches or even more than 40 inches – who is interested in a 4K monitor, now has the agony of choice. Naturally, the question of the perfect size cannot be answered on a flat-rate basis. It always depends on what you have in mind with the device and how you want to use it mainly.

First of all, you should get a sense of what the details in customs actually mean in each individual case. This is the only way to limit eligible devices and then take a closer look at them. 1 inch equals 2.54 centimeters. So, if you take the inch value of a screen and multiply it by the number 2.54, you get the value of the so-called screen diagonal in centimeters.

It’s also included with most devices, and it may be a little easier to imagine doing that than under a more abstract-looking inch. A 28-inch 4K monitor, for example, is characterized by a screen diagonal of 71 centimeters.

If you want to use your UHD monitor mainly for work, it depends on which applications you have in mind. Part of a 28-inch screen can be sufficient. For complex video or image processing, for example, it will not be a disadvantage to have a larger 4K screen in front of you. For the comfortable viewing of films is any way to buy a larger monitor to guess.

How important is the refresh rate?

The so-called refresh rate is specified in Hz. It has a decisive influence on how fluid the image is on the screen. For example, the difference between a refresh rate of 30 Hz and that of 60 Hz can be seen even with the naked eye. Because especially in graphically intense applications such as games can cause a stuttering and corresponding delays that adversely affect the flow of the game at 30 Hz.

At a refresh rate of 60 Hz, however, this can not happen. The movements are fluid and smooth. It is important that your computer is also equipped with a correspondingly powerful graphics card to really display the images in 4K. Passionate gamers are now even using 144 Hz screens – a technology that is still in the development phase.

Which connections should a 4K monitor have?

Almost every 4K monitor sold today has enough of the relevant connectors. It is important, above all, that HDMI 2.0 and DisplayPort 1.2 are on board and they are supported by the built-in graphics card in the computer. Because only then do you get the razor-sharp pictures really synonymous on the 4K display. Above all, the following three types of connection are relevant, which we would like to briefly introduce to you:

  1. HDMI – this letter combination stands for “High Definition Multimedia Interface”. The corresponding cables transmit picture and sound, as of HDMI 1.4, there is also an Ethernet channel. HDMI 2.0 is capable of supporting 4K images. In addition to the normal HDMI connectors, there are also Mini HDMI and Micro HDMI.
  2. DisplayPort – via DisplayPort (DP), image and sound can be transmitted in a maximum resolution of up to 7680 x 4320 or 60 Hz. Types of connectors include DisplayPort, Mini DisplayPort, and micro DisplayPort.
  3. DVI – DVI stands for “Digital Visual Interface”. Widely used for a long time to establish a connection between the screen and graphics card, the connection is now no longer quite up to date, since it can only transfer a certain resolution. There are DVI-A, DVI-D and DVI-I connectors.

Which display techniques are there?

Not only in terms of the various connections, but a layman can also quickly lose track of the topic 4K monitor. The same is true when it comes to the various display techniques. Because the 4K monitor is not the same 4K monitor. Therefore, before buying, you should not only pay attention to whether the device pleases you optically and is equipped with enough connections, but also a look at the display technology used makes sense. Essentially, these three variants are used:

  • IPS panel
  • TN panel
  • A panel

Screens with an IPS panel are particularly popular. This abbreviation stands for In-Plane Switching. Such a 4K monitor combines the advantages of VA panels and TN panels. The response time is usually in a very good range, the colors are excellent and also in terms of viewing angle stability know the devices to convince. A 4K display with an IPS panel is a true all-rounder, with which both ordinary users as well as photographers and game friends go well.

A 4K monitor with a TN panel is particularly suitable for avid gamers. If you like to gamble for your life, you should deal with this variant. The abbreviation stands for “Twisted Nematic”. The biggest drawback is that you have to sit in the middle of the 4K screen to get a decent picture. On the other hand, the response time is extremely fast and the monitors are usually very energy efficient.

If you ‘re a professional photographer, designer, or graphic artist, you’re best off with a VA Panel. This stands for “Vertical Alignment” and such screens convince with top values in terms of contrast, color reproduction and viewing angle stability. Only the response time is slightly higher than the other variants, so this technology is rather unsuitable for a gaming PC monitor.

What is important for image editing?

If you want to use your 4K monitor, especially for image editing, there are three important things to look at when comparing devices:

  1. contrast
  2. color depth
  3. brightness

A high-quality UHD monitor can be recognized not least by its contrast ratio. There are differences, with a common value of about 1000: 1. If the screen you prefer has this contrast ratio, you can access with a clear conscience.

As far as color depth is concerned, you are doing well as a normal consumer with a value of 8 bits per channel. This is called TrueColor. Such a 4K screen can display 256 color gradations of the primary colors and thus a total of about 16.8 million colors. Professional users choose 10 bits per channel (DeepColor). Here, up to more than a billion colors can be displayed.

The brightness is given in candelas per square meter (cd / m²). Good value is important if you work a lot in bright and brightly lit rooms. In normal use, with a 4K monitor around the 250 to 350 cd / m² is a sufficient value.

Why is HDCP 2.2 important?

As is often the case with the purchase of technical products, laymen are also faced with numerous shortcuts on the topic of 4K monitors, which seem like Bohemian villages to them. Some of these abbreviations, which are found in the product descriptions, are less relevant. Of considerable importance, however, is the abbreviation HDCP 2.2, which is why we would like to take up.

In short, this standard is novel copy protection, which was introduced in the year 2000 and is intended to prevent that reproduced on the 4K display material is copied in an illegal manner. For this purpose, a special chip is installed in the 4K monitor, which requires verification in conjunction with the other devices involved, such as your Blu-ray player.

Where do I buy my 4K monitor best?

You can order a 4K monitor via the Internet in an online shop of your choice. On the other hand, of course, you have the opportunity to visit the stationary retail and go to a shop of your choice. Both variants have both advantages and disadvantages.

If you are looking for a suitable 4K monitor in a specialist shop, you are not completely on your own but can take advantage of the expert help and advice of a salesman. In addition, you get a plastic impression of the device and can directly look at what condition the material has and how it is ordered to the processing. And most importantly: You can check the image quality with your own eyes.
