Same summary

The LG 34U650A-B curved 34-inch monitor offers an exceptionally wide working area and high QHD resolution, enabling efficient multitasking for office work, analytics, or working with multiple documents at the same time. With a 100 Hz refresh rate and IPS panel, it is also suitable for a smoother multimedia experience and occasional gaming, although for the most demanding gaming scenarios, professional models with higher refresh rates remain a better choice. Integrated USB-C, DisplayPort, and KVM functionality can be especially useful in modern multi-device environments and for home offices. The wide 21:9 aspect ratio and screen curvature make the monitor suitable for users who want a single, highly visible display as an alternative to two monitors, but for the optimal experience, it is also worth considering the size of the work desk and the appropriate viewing distance.

Answers to frequently asked questions

Is this ultrawide monitor suitable for work instead of two classic screens?

Yes, a 34-inch 21:9 monitor allows for multiple open programs or split-screen viewing, and often replaces a two-monitor setup. It is especially useful for writing reports, doing analytics, or working with spreadsheets.

What should I consider when connecting a laptop to a monitor via USB-C?

Before connecting, make sure your laptop supports video transmission over USB-C (DisplayPort Alt Mode or Thunderbolt), as not all USB-C ports support video. For more details on this topic, see our guide to multi-monitor setups .

Is 100 Hz refresh rate enough for occasional computer gaming?

For casual gaming and multimedia, 100 Hz is sufficient for most scenarios, but more demanding gamers (especially in fast-paced FPS games) will more often choose monitors with higher refresh rates.

What is the advantage of a curved screen compared to a flat one?

The curved screen allows for better focus on the entire width of the image and reduces eye movement, which contributes to comfort when working or viewing larger timelines and is especially useful with wide screens.

Is this monitor suitable for graphics and video work?

A monitor with an IPS panel and QHD resolution is good for basic graphics or video editing. For fully professional work where color accuracy is key, it is recommended to additionally check the requirements of individual programs and possibly choose models with higher color coverage standards.
