Nice and big as a 2nd screen next to my laptop

It's great to be able to work with an extra screen, even if it's so large that more tabs can fit on one screen.

Great screen. High resolution. I do have the zoom factor set to 125% in Windows, otherwise the text is very small. I can connect multiple sources (PC, laptop, etc.) simultaneously. The screen automatically recognizes which one is active. The connection ports are a bit difficult to reach, including the USB hub on the back. On the right side, there's a USB-A and a USB-C port. If you want to connect something here, the screen wobbles easily on the included stand. On the other hand, the stand is handy because you can adjust the monitor in all directions. The built-in speakers lack bass, so I don't use them. The screen itself is great for movies in the 21:9 format. It gives you a true cinematic experience.

According to our monitor expert
Sharp images: the Quad HD resolution lets you enjoy sharp images and detailed graphics in your game.
More overview on an ultrawide screen: you can keep a better overview of the playing field or open different windows and programs at the same time.
Clear from every angle: on the IPS panel, you can enjoy clear images from every viewing angle.
Less smooth gaming: due to the low refresh rate, you game with less fluid images, so you react more slowly to fast actions.
Stuttering images: the images in your game can stutter because of the high response time.
