Buying Guide To Choosing The Best 4K Monitor

Buying a 4K monitor is not easy if you are not familiar with the features you need and the quality aspects as well. For your help we have sorted some of the most important things for you to look for if you need to find the best:

Table of Contents

The Screen Size:

The first thing that comes to the mind of new buyers, as well as the ones who have purchase 4K monitors earlier in their lives, is the size of the computer monitor. Bigger monitors are expensive, take more space, offers better vision and experience.

If you have enough space to keep a big-sized 4K monitor you may prefer a bigger monitor but make sure you know the prices as well because as the size increases the price also rises. The screen size is measured through the oblique line across the screen from one to corner to another.

Aspect Ratio:

You may also consider the aspect ratio of the screen. Though 1:1 works fine but bigger screens are always better with broader vision and a curved surface to make sure you get indulged into the world shown through it.

Aspect ratio affects the way you get the images on the monitor. Because if the aspect ratio does not matches the videos being watches you may see black stripes on the screen either on the upper and lower horizontal margins or vertical margins.

You may understand the differences by considering the following figure. Here you can see the aspect ratio shown for the 4K Monitors is 4096x2160. It is the size of the monitor screen with respect to the horizontal resolution and the vertical resolution.
The 4K monitors or TV screen have the 4 times more pixels as compared to the 2K version and almost 9 times more pixel resolution s compared to the 720p screen.


The resolution in the 4K monitors combines with the aspect ratio to provide the real ultra-high definition results that most of the users are looking for. The possible 4K resolutions as given by the international telecom Union has the double resolution of an HD display and offers 3840x2160 pixels in 4K UHD whereas the 4K defined by the digital cinema Initiatives conforms to 4096x2160 pixels which are higher than that of the 4K UHD.

The higher the resolution means the more details you will get as defined by the higher number of pixels that provide smoother and clearer vision.

Some most commonly available resolution in 4K monitors and TVs are:

  • 4096 × 2560 with an aspect ratio 1.60∶1 or 16∶10
  • 4096 × 2304 with an aspect ratio 1.77∶1 or 16∶9
  • 3840 × 2400 with an aspect ratio 1.60∶1 or 16∶10 also called WQUXGA
  • 3840 × 1600 with an aspect ratio 2.40∶1 or 24∶10 or UW-QHD+
  • 3840 × 1080 an aspect ratio of 3.55∶1 or 32∶9 or Dual Full HD

Refresh Rate:

The refresh rate is another important spec that we should be taking care of when getting a 4K monitor. You may understand that when you need a monitor for your PC you don’t want to get an interrupted image or video while viewing the screen. A smoother vision is only possible when the screen refreshes and streams the video without any interruption. For this purpose, you have to make sure that the refresh rate is higher to keep the video running as smooth as possible.

Today in the 4K monitor you may expect to get a refresh rate of around 120Hz or it's multiple whereas refresh rate up to or more than 240 is just hypothetical and could be referred to as a false claim.

Response Time:

Just like the refresh rate, the response time is another important spec you need to be sure about. In contrast to the other specs, here for the response time, we need a lower response time to show a better video rather than a higher response time value that shows a blurred video. For clearer, the smoother vision you need lower response time so that the screen transitions through the video elements in a way that does not interrupt the vision and transforms smoothly.

Panel Type:

The panel technology is used to provide the display on the monitor screen. There are four basic types of panel technologies that have been introduced one after another to provide better and more advanced experience for the viewers.

The Main Types Are:

TN panels

Twisted Nematic panels were the ones at the start and had lost of issues and were not sophisticated enough to offer well-balanced imagery.

IPS panels

I-Plane switching panels overcame the disadvantages of the TN panels and gave better imagery and quality results.


Plane-to-line switching panels were better than IPS but more or less same with some of the advancements for better vision.


Vertical alignment panels are the most suitable panel type that you should be looking for in 4K monitors for balanced imagery. They offer higher contrast, light and brightness and sharp images with higher quality.

Viewing Angle:

Viewing angle may become important when multiple people would be viewing the screen but if you are the one and only person using it, it may not matter. Still, you may look at which angle or to which extent the monitor offers a good vision. Monitors that offers clear vision at a distant angle like up to 178-degrees, are expensive.

G-Sync and Free Sync:

G-Sync and Free Sync are the two features that enable gaming 4K monitors to keep the stuttering issue away from the view. The G-Sync feature is enabled with the help of a chip inside the monitor whereas the Free Sync uses the video cards to make sure the screen keeps on streaming the gaming visual without tearing off the vision and stuttering in the view.
