Our Verdict

The productivity king. The 21:9 ultrawide format is transformative for multitasking, and the USB-C hub with 90W charging means one cable for everything. Not for gaming or HDR content.

Frequently Asked Questions

Is ultrawide good for productivity?

Absolutely. Having two documents side by side without bezels in between is transformative. Most people who try ultrawide never go back to 16:9.

Does the USB-C charge laptops?

Yes, 90W charging works with most laptops including MacBooks and ThinkPads. One cable for video, data, and power.

Can I use it for gaming?

At 60Hz, it's not ideal for fast-paced games. Casual gaming is fine, but competitive gamers should look at higher refresh rate monitors.
