Best 4k Monitor Under 400 – Buying Guide

Since its appearance on television in 2013, 4k resolution has become immensely popular, promising a sharpness significantly higher than what we were used to.

What is 4K? 

In short, it corresponds to resolutions in which its horizontal display has approximately 4000 pixels, the most popular standard being 3840 × 2160 pixels, a format used by television and consumption in general. The name 4k is so-called because it has 4 times more pixels than the 1920 × 1080 resolution. 

It is easier to explain if we imagine our screen as a grid with rows and columns. While a Full HD screen, we have approximately 2 million frames, in a UHD monitor, we have about 8 million pixels available. Therefore, in the same space in 1920 × 1080, we have one pixel. In 3840 × 2160, we have 4 pixels. 

That produces sharper images and more excellent details and textures, almost as if we were right there. It is a leap in terms of clarity and sharpness, allowing digital artists, graphic design & video editing to be more productive and efficient by seeing details more easily.

About gamers, the possibility of playing your video game in 4k resolution becomes a dream experience. But not everything is rosy. The higher the resolution, the more expensive the product is, so if you want a 4k monitor, you will have to pay twice as much as one with similar features but in Full HD resolution.

Another less-favorable aspect of 4k has to do with on-screen scaling. 

Let me explain: 

by having more density of pixels per screen, the letters, icons, and interaction, in general, become smaller, becoming somewhat difficult to visualize. 

Although this is easy to solve, because you only have to go to your configuration to expand these elements to more than 100%, the recommended being approximately 150%. Another point that affects a lot at the time of purchase is that you require an excellent computer to support this resolution adequately. 

  • What do I need to view 4k content on my computer? 

In addition to the 4k monitor, your GPU must be pretty good, and some recommended are the GeForce GTX or AMD RX line. Of RAM, the minimum to run videos fluently is 4GB, although the ideal is 8GB. In case you want to play video games in 4k, you will also need a 3.6GHz i7 3820 CPU.

Which one is best, 27 inches or 32 inches?

If you are interested in buying a 4k gaming monitor, you can find the monitor 27 inches to 32 inches. Why this minimum size? Simple, a 4k resolution is so rich in detail, sharpness, and accuracy that you would not be able to appreciate it on a smaller monitor.

Also, the density of pixels in this size makes the different elements available on the screen scale to a smaller size, so a dimension smaller than a 27-inch monitor would have to strain your eyes to see them.

Maybe the real question here would be 27 inches monitors to 32 inches monitors?

Honestly, it is more a choice of personal tastes, but I will give you some information on both measures if you are undecided.

At 27 inches, you will be approximately 13 inches tall and 23 inches wide. The standard measurement in monitors used to work professionally in graphic design work within the large screen sizes. It allows having a more extensive format where it is easier to see details.

On the other hand, 32 inches includes approximately 39.8cm tall by 70.8cm wide. This format is not so popular. However, it can be a good option for those who want more space or perform tasks that require multiple programs, allowing them to have everything in view.

Which one is best, 27 inches or 32 inches?

Panel Types

There are several types of panels. However, the best known and most used are:

  • TN Panel: They can respond to up to 1ms and refreshment rates of up to 244Hz, becoming the favorite among gamers. Also, they are the cheapest. However, its image quality is not the best, losing even color and lighting when viewed from an angle.
  • IPS Panel: They have the best image quality when representing bright, contrasting, and accurate colors. Likewise, they can be viewed up to 178º without presenting distortion in their image quality. While they have a refresh rate of up to 144Hz, their response time is always slower than other types of panels, the standard being 5ms. Also, their production costs are higher, so they tend to be more expensive.
  • VA panel: They have a refresh rate of up to 144Hz and a standard response time of 4ms. Their colors tend to be contrasting and bright, although not as true to life as IPS. In terms of viewing angle, they are a bit better than TNs, but still generate image and color distortion when viewed from a certain angle.

Connectivity: What cable do I need to play 4k?

HDMI has become the quintessential connector in recent years. It can transmit high-quality digital audio and video signals in a single cable, replacing the old connectors. However, with time, different HDMI versions have come out that have been adapted and updated to the new technology.

Version 1.4 was the first to support 4k, only at a 30Hz refresh rate.

So if you want to play 4k on a 60Hz refresh rate, you need an HDMI 2.0 cable, which even has HDR support. There is also version 2.2 that supports 4k at 120Hz or 8k at 60Hz.

It is also possible to transmit UHD through a Display Port cable. However, we keep the HDMI cable because it is the one that is commonly included in the buying for its most accessible price.

Refresh rate and Response time

Response time is when it takes for a pixel to change from black to white, measured in milliseconds. A higher number creates motion blur, causing visual weakness and stress.

The refresh rate or refreshment rate is the number of images displayed on the screen in one second, measured in HZ. The higher this number, the playback will be more fluid and smooth, avoiding fragments or breaks.

Both points influence the gaming experience, so gamers prefer TN panels monitor with lower response times and refresh rates that can reach up to 244Hz.

HDR

HDR as High Dynamic Range is a mode that overexposes all image areas to have a much more contrasting and realistic result.

To carry out this process, there are different protocols, but the two most used features are:

  • HDR10: uses static metadata, that is, fixed measurements of light and color to the screen, regardless of the type of product or content. It is the most commonly used since it is free-standing, and therefore, companies do not have to pay for its use.
  • Dolby Vision: belonging to the Dolby company, this protocol sends custom metadata for each supported monitor. It is generally present in high-end products.

HDR-compliant monitor generally have a VESA DisplayHDR certificationA non-profit company dedicated to promoting and endorsing products in the electronics industry.

They are responsible for measuring the different HDR quality elements, including brightness, tonal gamut, bit depth, and rise time, to deliver the different levels of DisplayHDR available (DisplayHDR 400, DisplayHDR 500, DisplayHDR 600, DisplayHDR 1000, and DisplayHDR 1500).
