Pros and cons

According to our monitor expert

The 5K resolution lets you edit photos and videos with the sharpest details.
You can use multiple windows at the same time on the wide ultrawide screen.
The curved screen helps you work more ergonomically, so you’re less likely to get neck pain.
An ultrawide monitor takes up a lot of space, so your desk needs to be large enough.
Because the monitor doesn’t have a built-in webcam, you’ll need a separate one if you want to make video calls.

Description

With the LG UltraWide 40U990A-W, you can work with razor-sharp images and see every detail. This monitor has a 5K resolution, so you can use it for professional photo and video editing. Thanks to the ultrawide 21:9 aspect ratio, you can open more windows or programs side by side. For example, you can work in Adobe Premiere Pro and Photoshop at the same time. The curved display wraps around your field of view. This way, you don’t have to turn your head as much, and your neck won’t get tired as quickly. The DCI-P3 color space delivers high color contrast, so you can use this monitor for professional image editing with a wide color palette.
