The design with OLED technology and a wide 32:9 format makes particular sense where you would otherwise need two monitors, allowing for better visibility without borders between the screens. The advanced image and high refresh rate provide a top-notch experience even for serious gamers, while office users will benefit most in environments with plenty of desk space and sufficient viewing distance.

Answers to frequently asked questions

What are the conditions for comfortable use of such a large monitor?

For an optimal experience, we recommend a deeper desk (at least 80 cm) and proper adjustment of the monitor's height and tilt. The wide curvature allows for better viewing without eye strain at the extreme edges, and it is recommended to sit at a sufficient distance according to the screen size.

Does this model allow you to display images from multiple sources simultaneously (e.g. PC + laptop)?

Advanced ultrawide monitors often support PBP or PIP modes, allowing you to display content from multiple devices. We recommend checking the product manual for available connections and image sharing methods.

Is this monitor suitable as a replacement for two or more separate displays?

Yes, the ultra-wide 32:9 aspect ratio and high resolution make this model an effective alternative to two traditional monitors, especially when working with large timelines or many open applications. You can learn more about the benefits of this setup in our guide to multi-monitor solutions .

Is this monitor also suitable for professional image and video editing?

Thanks to OLED technology and extremely high resolution, it allows for high-quality display of colors and details, which is important for graphic designers, editors and photographers. Before making a decision, check whether specific color accuracy requirements (such as HDR support or specific color space standards) suit your work.

What should I pay attention to when connecting the device to a computer?

To take advantage of the full resolution and fast refresh rate, we recommend using an appropriate cable (e.g. DisplayPort or the latest HDMI), and for laptops, check in advance whether they support such high-resolution image output and the selected connection method. The issue of cable suitability and compatibility is crucial for optimal use.
