Introduction

My previous encounter with an ultrawide monitor made by Corsair didn't go particularly well. The quirky Xeneon FLEX 45WQHD240 made me realize two things: a 45-inch diagonal is simply perfect for a 21:9 monitor, but the 3440x1440 native resolution definitely isn't. The Xeneon FLEX suffered from low pixel density and subpar image sharpness, issues further amplified by the ever-present fringing caused by the non-standard subpixel arrangement of its WOLED panel.

Let's put all that behind us and focus on Corsair's latest ultrawide monitor, the Xeneon 34WQHD240-C. On paper, it stands a much better chance of impressing, as it combines the 3440x1440 native resolution with a 34-inch screen diagonal, which is a much better fit in terms of pixel density. It also features a 240 Hz QD-OLED panel made by Samsung Display, although it's still a first-generation QD-OLED panel, which means that the subpixel structure hasn't been updated to the latest and greatest, and there's a potential of experiencing seemingly raised black levels in a bright room, due to the lack of a polarizer.



The Xeneon 34WQHD240-C features a curved panel with a modest and practically imperceptible 1800R curvature radius. The radius is, of course, fixed, meaning the Xeneon FLEX remains the company's only monitor with an adjustable curvature. The Xeneon 34WQHD240-C is more practical in other ways, too. For instance, it offers full VESA mounting compatibility, allowing you to easily detach the supplied base and stand and mount it on a standard table or wall bracket for a cleaner setup. This is also one of the few monitors painted white, making it an ideal match for any white-themed build. Conveniently, that's exactly the case with my monitor-testing rig.

While the Xeneon 34WQHD240-C is primarily designed for gaming, it also boasts several productivity-focused features, such as a USB-C DP Alt Mode port with 65 W Power Delivery and a 4-port USB 3.1 hub with an integrated KVM switch. Let's see how this monitor performs in real-world scenarios and determine whether it justifies its $1,200 price tag.

The Package

The Corsair Xeneon 34WQHD240-C comes in a large cardboard box, covered in multiple sketches of the monitor and included parts, as well as a comprehensive list of its technical specifications. It's a utilitarian box that does a good job of protecting its contents.


Corsair was careful to include every cable you might need, including DisplayPort and HDMI cables, USB-C to USB-C and USB-C to USB Type-A cables, and two power cables. You also get an envelope containing a warranty card, safety and compliance information, two energy certification stickers, and a calibration report.
