The curved monitor is increasingly in demand among gaming lovers, graphics and video editing professionals, and also for work. The curvature of the monitor offers better immersion and involvement in viewing images to give the user the feeling of total participation, and better control of the viewing space.
When choosing a curved PC monitor, the first characteristic to look at is the type of curvature. For example, a monitor with 1000R curvature (1000mm radius) is more curved than a monitor with 1800R curvature (1800mm radius). In practice, the lower the number, the greater the curvature.
In addition to being a gaming monitor, this solution is remarkable for those who work on the computer with graphics programs or in any case with anyone who needs to access multiple resources at the same time, working on multiple windows and for better visual comfort.
The curved monitor, compared to flat screens, therefore solves the problem of space and accessibility to content and allows the screen to be divided into several different screens, improving productivity.
Best 4k Curved Monitor 2021
The efficiency of a curved monitor is seen at a short distance and in the front position, so the best 4K curved monitors are equipped with numerous eye protection systems. For example, we find filters for blue light, night mode, anti-glare, and flicker.
The resolution of the curved monitors ranges from Full HD from 1920 × 1080p to QHD 3440x1440p, up to Ultra HD 4k 4096 x 3840p.
In addition to the resolution, it is important to check the refresh rate, from a minimum of 60 Hz up to 120 – 144 Hz for mid-range monitors, to 200 Hz for top-of-the-range curved monitors. The refresh rate improves the image and together with the response time, between 1 ms and 5 ms, avoids trails, overlaps, and delays in the display between one frame and another.
To choose the best 4K curved monitor suited to our needs, we also check the outputs that allow us to access more content, from the USB and USB-C outputs to the HDMI output to the DisplayPort.
Below is the selection of the best 4K curved monitors to buy with their respective technical characteristics and prices.

How to choose a Best 4k Curved Monitor 2021 | Ultimate Guide
After having decided on the size and its resolution, at this point we see how to make a choice that is as aware as possible.
In the next paragraphs, we will analyze the main features to pay attention to in order to choose the monitor model that best suits your needs.
The first feature is panel technology. With LCD monitors, the panels available on the market are 3 ( TN, VA, and IPS ), each with its strengths and weaknesses.
The word TN stands for Twisted Nematic. In this case, we are dealing with a panel with a high response speed, low consumption, and high brightness, which is why they are also very cheap, but their defect consists in the annoying color variation when we look at it from a side angle.
Angular viewing is best in VA panels, which also feature a high black rendering, which perhaps makes them more suitable for movies. The IPS technology, on the other hand, has a slower response time than the others but the color rendering is superior, even when viewed from side angles.
Response time and refresh rate
Response time is another very important factor, as is the refresh rate.
The latter is expressed in HERTZ and it is good to remember that it does not affect the quality of the image so much but its fluidity.
Here you have to be careful, because the refresh rate, which could be 120 or 140 Hz, must be measured against the performance of the graphics card. It is not enough to have a high frequency if the graphics card is not able to process a number of frames per second adequate to the frequency of the monitor.
The response time, on the other hand, is measured in milliseconds and tells us the speed with which the pixels pass from black to white, in a more technical way it is said the time it takes to pass from one grayscale to another.
Ever heard of the ghosting effect?
This is the effect where a moving image on the screen tends to leave its own trail. This is due to an excessively slow response time. Usually, a value beyond which not to rise is 8ms.
Video inputs and extra features
Finally, there are the extra features, which in some cases can make a difference.
The first thing to pay attention to is definitely the outputs that the monitor has, so you can get an idea depending on the device you need to connect it to.
In addition to the traditional HDMI output, a Dual Link output or a DisplayPort may also be of interest.
The presence of at least one USB port is another aspect to consider, in some cases, it could be very useful. If you do not want to equip yourself with a sophisticated external audio system, then the presence of integrated multimedia speakers and their quality must also be evaluated.
Then there is the far from the second issue of convenience. Unless you rely on impromptu inventions, it may be important to have a monitor that has some sort of height and tilts adjustment system.
Most of the standard monitors in circulation do not provide this kind of option or do not allow particularly fluid movements, while a good adjustment of the height and the horizontal viewing angle can greatly affect the gaming experience.
Resolution of a curved gaming monitor
Starting from the origin, a pixel is the smallest part of the display, thus a tiny dot visible when the computer screen is turned on.
Then, once all these dots join each other, they form images, the very ones visible on the PC monitor.
At this point, it is possible to decipher the term resolution. It is a numbering that is given by multiplying the vertical pixels with the horizontal pixels. The larger the number of pixels, the higher the resolution.
HD (High Definition): this term indicates a high-resolution monitor. It can be 1280 × 720 or 1920 × 1080. Often it reads HD Ready, but this happens when a monitor does not have the high-resolution feature, so it is always good to check before buying it.
The formats currently available on the market are 720p, 1080i, and 1080p, where the letter “p” indicates a real progressive resolution, while the letter “i” indicates a kind of computer system that aims to add pixels to improve image quality.
Full HD (Full High Definition): is considered an evolution of the HD format. The only thing is that this resolution must have cells of at least 1920 × 1080 pixels, which means free of any compression or reduction, as was the case for the previous resolution.
2K: is an intermediary between Full HD and 4K. There are several monitors with this type of resolution (2048 × 1080), but few are purchased because there are no movies, games, or TV programs with this resolution on the market, but they go directly to 4K or remain stable at Full HD.
4K: A big leap in quality has been made here. The resolution consists of 3840 horizontal pixels and 2160 vertical pixels. There are no television programs at this resolution, but it is possible to find movies or TV series on some platform. DVDs have also been put on the market with such graphics, obviously, they have a higher cost.
The main technologies
AMD FreeSync and NVIDIA G-SYNC
Before explaining the function of these two technologies, it is good to introduce the meaning of refresh rate, that is the monitor refresh rate which is measured in Hz (Hertz). This parameter is of vital importance in gaming monitors, in fact, it varies. The video card sends frames to the monitor and, if the monitor frequency is 30 Hz, it means that it updates the screen 30 times per second. This is why it is important to have a good refresh rate, otherwise, there are shots or images that are not fluid, which is not very nice to gamers.
At this point it is possible to talk about the two technologies. Both are based on a variable or adaptive refresh rate and, thanks to them, the video card communicates with the monitor, starting a real synchronization to improve image quality. However, there are differences between the two.
For example, the G-SYNC technology was the first to be designed at the hardware level, that is, it is managed by a particular module made from materials characteristic of NVIDIA. The advantage is that it prevents ghosting by improving the refresh rate. Ghosting is a replica of a part of the image being broadcast, superimposed on the new frame.
As for the FreeSync technology, it is managed by the monitor firmware and the video card drivers, so not by proprietary components as was the case with the previous technology. In fact, AMD FreeSync is based on open systems, and this is a benefit that should not be underestimated. This technology is based on a connection that takes the name of DisplayPort and implies a decrease in the price of the monitor.
In short, if you don’t want to spend a lot, you can turn to AMD FreeSync by choosing a compatible video card and monitor; if instead you want to aim for the highest quality, then it is good to turn to AMD G-SYNC, spending a little more.
HDR (High Dynamic Range)
It is a very important technology because it improves the images in those areas where there is a lot of little light.
It makes them more realistic by increasing the level of detail in each light shade. HDR technology is not only found on smart TVs but can also be found in gaming monitors, because it samples the variation of any dark or bright tone within a broadcast scene, avoiding overlapping bright images or loss of detail for images. dark.
HDR is possible because it uses a common electro-optical transfer function, that is, it reproduces images on the monitor that are almost identical to reality. The goal is to make sure that the human eye does not distinguish what it sees inside the screen from what it sees outside the screen, making everything homogeneous. Hence, HDR technology is undoubtedly better than SDR technology, which is common for older monitors.
Motion Blur Reduction Technology
This technology was born with the aim of breaking down the Motion Blur on the monitors, thanks to a stroboscopic effect that provides for activation and deactivation of the backlight at high frequencies.
This type of effect is very close to reality, or rather, to what is visible and perceptible to the human eye. Motion Blur generates a kind of trail during a rapid change of view, just what happens to all of us when we quickly turn our heads while observing objects that have a minimum of their own light. The most classic examples are a lighted lamp, the headlights of a car, a candle, etc.
It does not cause any increase in the graphics sector but is only adopted to add that touch of augmented reality. In addition to gaming monitors, it can be activated on professional cameras.
Flat or curved screen?
Between a flat-screen and a curved screen, almost nothing changes, apart from their external structure. The monitors, in fact, have different resolutions (those described above), but there is no curved screen that has better graphics than a flat-screen or vice versa. What changes is their construction method?
What a curved screen offers is greater involvement and sense of immersion, due to the different angles compared to a flat screen and offers a better view, only if the person is in a correct position respecting the focal point.
The contrast is more or less similar, in the sense that it is obvious that the more you deviate from a central position, the lower the image quality appears.
From an aesthetic point of view, we must give a point in favor of the curved-screen because it appears more elegant, more modern, and avant-garde, so much so that it takes on a certain charm even when it is switched off. There are no big differences in quality between the two because the resolutions are the same, but the price goes up for curved screens.
