Same summary

The Samsung LS37D800UAU monitor with a 37-inch diagonal and high 4K UHD resolution is intended primarily for users who need an extremely wide working surface for business use, more demanding multitasking or advanced media tasks. Due to the combination of a VA panel, HDR10 support and USB-C functionality with a KVM switch, it is particularly suitable for environments where fast switching between different devices is important, e.g. laptops and desktop computers. Such ultrawide monitors may require slightly more space and a suitable viewing distance, so they are not optimal for very limited desks or just basic home use. An important advantage of this model is the ability to easily integrate multiple work processes on one screen, which is useful both in offices and for demanding home users.

User view

This model is most often chosen by business users who manage large spreadsheets, analyze data or develop software and for whom a clear organization of multiple windows at the same time is crucial. The ultrawide format and high resolution significantly facilitate multitasking and replace the setup of two screens, while also proving to be a very practical solution for graphic editing, video production or in-depth work with timelines. For users who take gaming as an occasional relaxation, the large diagonal and HDR bring greater involvement in the action, although the monitor itself is not optimized for the most demanding competitive gaming.

If you are considering an effective replacement for two classic monitors or are looking for the optimal size based on the available space, we recommend checking out our guide on choosing a monitor size - the article answers many practical questions regarding ergonomics and space requirements.

Answers to frequently asked questions

Is a 37-inch ultrawide monitor suitable for a regular desk?

For an optimal experience, it is recommended that the depth of your desk allows for a comfortable viewing distance (approximately 70–90 cm), as wide monitors take up more space and are less suitable for smaller work surfaces.

What does the KVM function mean and when does it come in handy?

A KVM switch allows you to easily control multiple computers on the same monitor using a single keyboard and mouse set - a feature especially useful for users who switch between their personal and work computers.

Is this monitor suitable for video editing or graphic design?

With its high resolution (4K UHD), large display area, and HDR support, it's perfect for video editing, timeline work, and basic graphic design. For more demanding professional color standards, check out other models with more advanced color reproduction.

What is the difference between using one large monitor and two smaller ones?

This type of ultrawide monitor provides a continuous wide workspace without interface interruptions, making it easier to work with large documents or timelines. You can read more about the practical differences in our guide to dual monitors for greater productivity .

What to check before connecting a monitor via USB-C?

Make sure your laptop or computer supports USB-C (DisplayPort Alt Mode or Thunderbolt). If your device doesn't support this, we recommend using standard connectors such as HDMI or DisplayPort.
