Design and Features
The Corsair Xeneon 34WQHD240-C has a unique design that is dominantly classier than it is gamer-centric. The monitor has a white chassis all around, so it will definitely stand out against its matte black competitors. The screen has a bezel-free design, but it still has inner bezels like most OLED monitors.
It’s larger than most 34-inch ultrawides simply because it has a more extravagant stand. The whole unit needs 11 inches of depth, so it might offset some of your main peripherals if your desk is smaller than a gaming variant. Its total weight reaches 22.05 pounds, so extra care is necessary if you want to move it around.
Its build quality is fantastic despite the fragility of OLED monitors, which are usually thinner and lighter. Corsair has plenty of experience in this regard, offering better material quality and precision in most gaming gear categories, like cases and coolers. We didn’t see any flaws or signs of considerable wobbling like what other cheaper models have.
The Corsair Xeneon 34WQHD240-C has a joystick for easy access to its OSD. Other high-end models like Samsung’s representative includes a remote, but those only become necessary if this model also had smart TV features. We’re very okay with a joystick especially since they do not raise the price that high.
The included stand offers tilt, swivel, and height adjustments for your comfort and convenience. Pivoting wasn’t included, but that’s understandable since this is an OLED model. You can use VESA mounts, but we’d rather use the included stand since it provides excellent stability.
The Corsair Xeneon 34WQHD240-C’s connectivity layout includes DisplayPort 1.4 and two HDMI 2.1 slots, but it also has a 65-watt USB-C port with DP Alt Mode. There is a second USB-C slot with 15 watts, along with four USB 3.1 connectors and a 3.5mm jack for accessories or peripherals.
There are no speakers, but that’s understandable since monitors like this deserve better. You get better mileage with a gaming headset which have the necessary oomph for the monitor’s primary purpose. It would be nice to have an upgraded set because of the price, but its not a deal breaker for us.
Display and Performance
The Corsair Xeneon 34WQHD240-C boasts a 34-inch ultrawide OLED panel with a 3440 x 1440 resolution, a 240Hz refresh rate, and a 0.03ms response time. It has 250 cd/m2 typical and 1000 cd/m2 peak outputs, while the contrast is listed at 150000:1 like most modern OLED monitors. This model is HDR 400 True Black certified, indicating that it can produce deeper black or dark colors and brilliant HDR performance.
1440p ultrawides are great for gaming since they offer upgraded sharpness and visuals thanks to the wider aspect ratio. You get more room to maneuver your tasks, but you also get to enjoy a wider FOV from your favorite titles. The best part is that it’s not as demanding as a 4K screen, so 240 FPS is a more achievable goal alongside the benefits mentioned above.
The Corsair Xeneon 34WQHD240-C covers more than 100% sRGB and 97% DCI-P3 for stunning color in games and movies. Its default accuracy had a deltaE average of 2.64, so it’s decently balanced as far as gaming monitors are concerned. Most users won’t need to calibrate it out of the box unless they plan to use it for professional endeavors.
Using a colorimeter on the Corsair Xeneon 34WQHD240-C reduced the dE average to 1.07, making it more ideal for editing and content creation. However, you will need a colorimeter to achieve that since every panel is different. We can only recommend the purchase if you will use the monitor for color-critical work, but its impractical otherwise.
The OLED panel’s brightness reached 248 cd/m2 in SDR and it peak window reached 1014 cd/m2 when HDR is active. Its contrast is near infinite, so the monitor is capable of deep, true blacks which translate to compelling dark scenes. Its fantastic for HDR games and movies, and not even the mini-LED variants will be better in that regard.
Panel uniformity for the test sample was excellent since there was no backlight to cause leaks. Some clouding can happen in contrasting scenes, but it is barely noticeable since each pixel can do its own thing for more accurate imaging. The only danger to OLED tech is burn-in, but that can be prevented with proper care.
The Corsair Xeneon 34WQHD240-C’s pixel response time is nearly instantaneous as well since it doesn’t have to wait or sync with a separate backlight. Fast-paced images are crisp and clear, so games like CSGO 2 or Valorant look amazing on them.
The Corsair Xeneon 34WQHD240-C is compatible with FreeSync and G-Sync for stutter-free gaming. This is an expensive monitor, so having VRR for both is essential, so you don’t have to buy another display if you switch to the other GPU brand. Its input lag sits at 3ms at 240Hz, making it one of the fastest 240Hz ultrawides in the market.
Thoughts on the Corsair Xeneon 34WQHD240-C
The Corsair Xeneon 34WQHD240-C is a fantastic OLED gaming monitor when it comes to performance and design. It has a vibrant and true-HDR capable OLED ultrawide display that provides brilliant imagery for games and movies. Its packed with a lot of desirable features like USB-C connectivity, making it a better investment than some of its limited competitors.
It falls behind when it comes to default accuracy and peak brightness, and most would expect perfection at this price. However, there is not a massive gap, but we did mention it for the meticulous gamers and enthusiasts out there who often go with the best of the best. It still is a fantastic buy, even if there is some room for improvement.
Pros:
- Fantastic Color Richness and HDR
- Attractive Design with Lots of Features
- USB-C
- Single Cable Connectivity
Cons:
- USB-C Limited to 65W and 15W
- Lower Peak HDR Brightness
- Poor Default Accuracy
