A true frameless monitor that offers a border-to-border layout. The monitor supports a resolution of up to 3840 pixels by 2160 pixels, and it comes with an IPS display for better quality images. The monitor has a built-in HDMI port, along with a DisplayPort input. Support for 4K graphics provides better graphics and the ability to enjoy games in a greater resolution.

Support for 4K graphics is not yet offered by a significant number of graphic cards and other devices that may be connected to the monitor. The price of the monitor is also on the higher side compared to some of the competitor options out there.

What Really Matters?

There are some features to consider when looking for a new 4K monitor. The following are some of the most basic features that will help you decide.

Color Accuracy

One of the things that will affect your ability to understand visual information is the monitor’s depth of the color. Although technologies are improving daily, some manufacturers have completely forgone color clarity and depth.

It is important to note that the need for color accuracy will depend on the monitor’s uses. For those who play games, one may need color-sensitive videos in some cases, but you may not always need the most accurate colors.

Nonetheless, the policy remains: the better the color accuracy, the more reason there is to choose that monitor.

Response Time

Response time is the amount of time taken for a specific pixel to change its color. As frames move, the pixels may fail to synchronize, which creates the “ghost effect”, where some pixels are left with colors from previous frames.

If you’re a gamer, this might be very frustrating; you may have to wait for the pixels to synchronize every time a new frame appears. Mind you, videos and games offer new frames every second. Although most recent 4k monitors have a strong response time, the response time might vary between brands or models. The best response time is anything in the range of 1 to 4 ms.

Monitor Size

One of the considerations that you should make–which most people fail to make when buying 4K monitors–is the distance you will sit from the monitor. If you sit close to the 4k monitor, a smaller screen size will likely be preferable.

What’s in Right Now?

Technology has improved considerably, and 4K monitors have not been left behind. People are beginning to realize that the monitors can be used for several functions, such as television, computer monitors, etc.

Curved Screens were initially introduced for TVs. They allow the user to see the screen from extreme angles on either side of the screen. Today, 4K monitor manufacturers have adopted this technology; there has been a rise in monitors that utilize it. These types of 4K monitors are best suited for gamers.



These are the most basic of 4K monitors. In most cases, the monitor’s size determines its pricing, and at this price range, expect to find smaller monitors of 24 inches and below.

If you find a larger screen size, you might have to compromise on the color accuracy or the response time. Or maybe, the screen size is large, but the general quality of the monitor has been compromised. In these cases, the monitor might lose its original hue within a short period of use.


Again, given that the monitor size is the main features expect monitors that are between 24 and 42 inches.


In most cases, these are monitors whose screen size is greater than 42 inches. However, this still depends on the brand and the features of the monitor. In any case, it is necessary to consult reviews before buying anything.


What is a 4K monitor?

Most conventional monitors have a pixel count of 1290 x 1080. However, 4K monitors have a count of 3840 x 2160 pixels. This gives it a resolution that is almost 4 times better than that of conventional monitors.

Is a 4K monitor worth it?

4K monitors are more expensive compared to other monitors. However, they are certainly better in many aspects. If you have the money, you won’t regret investing in 4K monitor.
