How to choose your ultrawide 21:9 PC screen

#1 - The resolution

The most interesting resolutions for an ultrawide screen are between 3440 x 1440 to 3840 x 2160 for 4K screens, and 5120 x 1440 for 5K screens. The 5K ultrawide screen offers extra space compared to smaller screens. In any case, as the resolution increases, so does the image quality.

#2 - Flat or curved screen?

The ultrawide screen gives you new dimensions, a sharper image, and sharper contrasts. Depending on your needs, however, you will have to choose between the flat screen and the curved screen. If your screen is more for gaming, choose a curved screen to get a perfect immersion. For office automation or development, you'll need great line accuracy, and a flat screen would be ideal.

#3 - The display technology

IPS technology is particularly popular for image processing, office automation or video. It displays vivid images and perfect contrast. This is also why gamers appreciate its features. TN technology is the most affordable, but it works best on small screens. VA technology offers exceptional contrasts and brings out the angles of vision ideally.

#4 - The refresh rate

The refresh rate defines the speed with which the image is displayed on the screen. For watching a movie on a PC or for gaming, you're better off choosing a screen with a refresh rate between 100 and 120 Hz. For office work, a refresh rate from 60 Hz will be more than enough.

#5 - The connectivity

Ultrawide PC monitors have various ports such as USB or Jack ports, and even memory card readers. With these readers, you can directly display photos without going through the PC. Some ultrawide monitors have built-in speakers even though you shouldn't rely too much on them for sound quality.

What does the ultrawide screen bring to office automation and multimedia?


The ultrawide screen is a trendy equipment of the current era. This screen gives users the opportunity to get rid of the black bands that appear at the top and bottom of the screen when watching feature films. Indeed, this type of film is shot in cinemascope format whose resolution is close to the 21:9 format. In this case, the diffusion on classic screens generates the automatic appearance of these bands so that the integrity of the format is preserved without distortion of the image. This letterbox effect does not exist on an Ultrawide screen, which makes these borders disappear for better immersion, both at work and when watching movies or playing games.

Other than that, the ultrawide screen confers comfort in office work, so as to allow dual screen display of several applications simultaneously. This can even be done without the need for additional cables and connections, and especially without the headbands between the individual screens. Even better, the resolution is wider, so, more comfortable.

For developers, an ultrawide screen makes it easy to reread lines of code. On the other hand, this type of screen allows you to work on large spreadsheets, and many columns. For multimedia editors, this format allows the optimization of productivity, in that it is more convenient for editing video or music, and the display of a larger time line.

Finally, in terms of connectivity, the ultrawide screen has more options, allowing for smoother navigation, more connections and enough space to use multiple applications simultaneously.

The different types of ultrawide 21:9 PC screens

The ultrawide 21:9 flat PC screen

Like any ultra-wide PC monitor, the flat panel monitor offers a wider view, as well as more clarity on images and lines. It's ideal for those looking for comfortable viewing in a professional environment. For example, those who work in graphics will appreciate that straight lines are not distorted, but will also draw straighter lines. Also, people who are used to working on multiple windows will feel comfortable having all the necessary documents in front of them.

In terms of performance, the ultrawide flat screen offers a resolution in the range of 3440 x 1440 px and 2560 x 1080 px, a particularly interesting display quality. Of course, you should take into account that when looking at the screen, you will be closer to the center than to its edges. As a result, your eyes will feel a two-dimensional sensation of the image. The flat screen can be hung on the wall, and it's easy to angle it in either direction.

The ultrawide 21:9 curved PC screen

The curved screen is without context a monitor that is on the rise, both in terms of aesthetics and performance. With its attractive design, it was simply designed to offer a more immersive experience, especially for gamers who are fond of 3D games or movie lovers or those who like to watch matches on their PC.

The curved screen also ensures a better display resolution. The curved aspect of the screen offers a panoramic effect, and each point, whether in the center or at the edge of the screen, will be at equal distance from the viewer. You'll have that immersive feeling that gives a special atmosphere in 3D video games, but you won't have to turn your head and neck. It's a shame, however, that you can't mount the curved screen to the wall.

The ultrawide 21:9 OLED PC screen

Flat or curved, the ultrawide21:9 screen uses either LED backlighting or OLED technology. The choice of either technology affects the display on the screen, as well as the quality of the image.

LED backlighting is energy efficient. LED lights illuminate liquid crystals providing a beautiful image quality, regardless of the size of the screen. Therefore, LED technology is perfect for gaming and office use. The OLED screen no longer uses a backlight filter, but operates on the diodes to make them emit light. This results in better image contrast, ideal for those who use the ultrawide screen for precision tasks. In terms of cost, backlight technology is more affordable than OLED.

Ultrawide 21:9 PC monitor or a dual screen setup?

Ultrawide 21:9 PC screen

The ultrawide 21:9 PC screen gives you a new dimension in the videos you watch or the games you play. You will be able to live unique immersive moments, especially if you are fond of 3D games. Not only the dimensions of the screen offer a wider field of vision, but the images will be sublimated by the beautiful technical performance of the screen.

However, given the selling price, it is clear that the ultrawide screen is not accessible to all budgets. Moreover, its imposing dimensions will require a larger work space. Although it displays clearer and more accurate images, it can only be divided into 4 zones.

Dual screen assembly

The first advantage of the dual screen is without context its much more affordable price, since two screens will cost less than one ultrawide screen. It will also be easier to manage the workspace, since with two screens, you will be able to deploy up to 8 windows, a valuable advantage for those who use several applications. In addition, you will have the option of rotating one of your screens.

With a dual or triple screen, however, you'll need two or three cables, creating extra space. If you want to experience immersion with two screens, the side edges of the frame can't be overlooked.


The ultrawide 21:9 screen is ideal for gamers to give them a wider view, as well as full immersion. The multiple screen is necessary to display your documents or applications while having a main screen in front of you to perform your tasks.

Why buy an ultrawide 21:9 screen?

The fun and enjoyable solution for 3D gaming.

The 21:9 widescreen PC display is obviously created for gamers who are fond of 3D games and will enjoy a nice immersive experience. Again, they will feel like they are in the thick of the action. Once again, you'll be able to really dive into a virtual reality.

A wide field of view

A wider screen will offer you a better comfort in the actions you will undertake. In addition to the beautiful images, visibility is better, especially since the technical performance is greatly improved, and your work will be more precise.

A special design

It's true that the shape of an ultrawide 21:9 screen is striking. The design is modern, futuristic and will be an additional contribution to your interior design. Of course there is the oversized screen, sometimes with lighting, but the screen stand also has its own special charm.

Valuable ergonomics for office tasks

Imagine all your work documents that you can scan with a single glance all your applications. And not only that: you don't have to turn your head and neck every time, while no point will escape you. This advantage will save you precious time and make you more productive.

When it comes to movie viewing

The ultrawide screen allows you to watch movies as if you were in the theater. Indeed, the ultrawide screen is automatically configured to watch them. Movies will look better and more real than on standard screens, and you won't see the black bars above and below your screen.

Versatile and convenient

The 21:9 ultrawide PC monitor is versatile because it has a variety of connectors. Thanks to HDMI, you can connect it to your game console to enjoy beautiful graphics if your TV is limited.

Proper installation for better immersion

A screen at eye level, your seat in the right place and of course, the speakers at the same level as your ears are the guarantee of aural and visual comfort. Not only will you benefit from this comfort, but it's also the best way to preserve your visual and auditory health.

Think about protecting your eyes from blue light

You can do this in different ways. Either you opt to wear anti blue light glasses, or install a filter on the screen. Software that eliminates this harmful light is also available on the market. They act by modifying the screen's color settings.

Regular cleaning

If your screen is maintained periodically, it is not necessary to use a specific product to clean it. Simply dust it and wipe it with a damp cloth to remove any remaining grime. Dry it and shine it with a soft cloth to finish. Remember to unplug the screen beforehand.

A protective cover to avoid scratches and dirt

Think about covering your ultrawide PC screen when you are not using it. As much as possible, avoid exposing it to external aggressions. This protection will help prolong its life.

Use the right type of cable

The interface of your monitor with the PC is the cable. If you use an external graphics card, it will have the following connectors: HDMI, Display port and DVI. VGA has been abandoned by the newer generations. For a 4K or 1080p display at 144 Hz, we recommend HDMI, which is the current standard and is newer than DVI.


21:9 curved screen or not ?

The choice between a curved or non-curved 21:9 screen depends on the use. The curved screen is not suitable for those who do graphic design, as drawing straight lines on this type of screen becomes complex. On the other hand, the size of ultrawide screens gives a two-dimensional perception of the image that curvature can correct while enhancing immersion.

G-Sync or FreeSync compatible 21:9 screen?

When opting for a 21:9 ultrawide screen, it is important to know which technology is suitable for adaptive vertical synchronization. G-Sync (Nvidia) and FreeSync (AMD or Nvidia) are compatible with this display, and help prevent image tearing on the screen. These technologies benefit from an automatic adaptation of the refresh rate with that of the GPU.

Why install tweaks?

Tweaks are tools that allow you to increase the functionality of favorite applications on iPhone and iPad. Even better, they allow the modification of some non-jailbroken applications. Basically, tweaks represent a way to upgrade other applications. The tweaks are dedicated especially to Apple's portable devices, and they also contribute to the activation of background audio support on Youtube.

Why is a 21:9 screen better than a 16:9?

The 21:9 screen is better than a 16:9 insofar as this format allows to gain in display surface. Thus, the screen displays very detailed graphics for a better immersion in simulation games (air, space or car). In addition, the field of view is wider, with an increased viewing angle, without the need for additional peripherals.
