The Corsair XENEON 27QHD240 is a 27-inch gaming monitor with a 1440p resolution. Alongside the Corsair XENEON FLEX 45WQHD240, it's one of two OLEDs that Corsair has, and it uses the same panel as the LG 27GR95QE-B and ASUS ROG Swift OLED PG27AQDM. It has everything you'd expect in a high-end gaming monitor, like a 240Hz refresh rate, variable refresh rate (VRR) support, and HDMI 2.1 bandwidth. Although it's focused on gaming, it has a few features for other uses like productivity, as it has a KVM switch that makes it easy to use the same keyboard and mouse connected to the monitor with two different sources. It has a few settings to combat permanent burn-in, which OLEDs are prone to, and Corsair advertises that there's a warranty against burn-in, but it's unclear what specific burn-in is covered as the warranty excludes normal wear and tear.
Our Verdict
The Corsair XENEON 27QHD240 is amazing for PC gaming. Its 240Hz refresh rate is great for competitive gaming, and it has VRR support that works with any source to reduce screen tearing. Motion looks sharp no matter the refresh rate you're gaming at, and it has low input lag at high refresh rates, but it increases at 60Hz. It also has distracting VRR flicker with changing frame rates, which is noticeable in dark scenes. On the plus side, it displays deep and inky blacks without blooming, making it a great choice in dark rooms.
- 240Hz max refresh rate.
- Supports all common VRR formats at any refresh rate.
- Near-instantaneous response time.
- Perfect black levels.
- Input lag increases with 60Hz signals.
- Distracting VRR flicker with changing frame rates.
The Corsair XENEON 27QHD240 is incredible for console gaming. It has HDMI 2.1 bandwidth, so it supports any signal from the PS5 and Xbox Series X|S, including downscaled 4k @ 120Hz signals. Gaming feels responsive thanks to its low enough input at 120Hz, but its input lag increases at 60Hz, which is disappointing for playing reaction-based games. Luckily, your games also look realistic thanks to its excellent HDR picture quality with its deep blacks, but it doesn't deliver vivid colors.
- Supports all common VRR formats at any refresh rate.
- Near-instantaneous response time.
- Perfect black levels.
- Takes full advantage of modern consoles.
- Input lag increases with 60Hz signals.
The Corsair XENEON 27QHD240 is decent for the office, but there are some limitations. Its wide viewing angles and great ergonomics make it easy to adjust the screen, like when you need to show something to a coworker. It also has a few office-oriented features, like a KVM switch, so you can control two devices with the same keyboard and mouse. While it has fantastic reflection handling, it doesn't get bright enough to fight a lot of glare. Sadly, it has text clarity issues due to its RWBG subpixel layout, and OLEDs also risk permanent burn-in when exposed to the same static elements over time.
- Fantastic reflection handling.
- Wide viewing angles.
- Great ergonomics.
- USB-C port and KVM switch.
- Text clarity issues due to RWBG subpixel layout.
- Limited peak brightness and aggressive ABL.
- Risk of burn-in with static elements.
The Corsair XENEON 27QHD240 is great for content creation, but there are limitations. It displays a wide range of accurate colors in SDR, but you still need to calibrate it for the best accuracy possible. It also has great ergonomics and wide viewing angles, which help if you often need to share your screen with a coworker or client. However, there are text clarity issues due to its subpixel layout, resulting in color fringing and text that isn't very sharp. Also, OLEDs risk burn-in with exposure to static elements over time, like if you always have your editing software open.

The Corsair XENEON 27QHD240 is excellent for HDR. It displays deep blacks next to bright highlights in dark rooms, and there isn't any blooming either. However, it doesn't get bright enough in HDR to display vivid colors, and it has tone mapping issues.
- Perfect black levels.
- Small highlights pop in HDR.
- No blooming around bright objects.
- Limited HDR color volume.
The Corsair XENEON 27QHD240 has exceptional picture quality in SDR. It displays deep and inky blacks without any blooming, and it also displays a wide range of colors.

The Corsair XENEON 27QHD240 has great color accuracy. Although it has a dedicated sRGB mode, its accuracy before calibration isn't anything special as most colors are off, and you need to calibrate it for the best accuracy. That said, the image remains consistently accurate across the entire screen, as it doesn't have any uniformity issues.
- No uniformity issues.
- Needs calibration for best accuracy.

Popular Monitor Comparisons
The Corsair XENEON 27QHD240 is an amazing PC gaming monitor with incredible motion handling, a high refresh rate, and perfect black levels. It can please any type of gamer with the combination of the fast refresh rate and premium picture quality. On top of its amazing gaming performance, it even has a few extra productivity features compared to some other monitors. However, considering it doesn't get as bright as the ASUS ROG Swift OLED PG27AQDM and has higher input lag at low refresh rates, the ASUS offers better value. Still, if you can find it for less than the ASUS and the LG 27GR95QE-B, it might be worth getting if its downsides don't bother you. The limited three-year warranty on the Corsair is positive compared to the LG and ASUS, but the warranty also has some exceptions.

The Samsung Odyssey OLED G85SB S34BG85 and the Corsair XENEON 27QHD240 are different types of OLEDs. The Samsung has an ultrawide display with a QD-OLED panel, allowing it to get much brighter with more vivid colors than the Corsair. On the other hand, the Corsair has a higher 240Hz refresh rate, which is ideal for competitive gaming, and it supports 4k signals up to 120Hz from the PS5 and Xbox Series X|S, which the Samsung monitor can't do.
The Dell Alienware AW3423DWF and the Corsair XENEON 27QHD240 are different types of OLEDs. The Dell has an ultrawide display with a QD-OLED panel, allowing it to get much brighter with more vivid colors than the Corsair. On the other hand, the Corsair has a higher 240Hz refresh rate, which is ideal for competitive gaming and supports 4k signals up to 120Hz from the PS5 and Xbox Series X|S, which the Dell can't do.
The Corsair XENEON 27QHD240 and the LG 27GR95QE-B use the same panel and perform similarly. However, there are still a few differences as the LG gets brighter in HDR and has improved color volume, while the Corsair has less overshoot with fast-moving objects. The Corsair also has a few extra features, like USB-C ports and a KVM switch. They both support HDMI 2.1 bandwidth, but the LG supports 48 Gbps bandwidth compared to 24 Gbps on the Corsair, so your source doesn't need to use compression for demanding signals.
The Corsair XENEON 27QHD240 is a smaller model than the Corsair XENEON FLEX 45WQHD240, and they share many similarities, but there are a few differences too. The 45WQHD240 has a wider and larger 45-inch screen and 3440x1440 resolution, so you can see more of your game at once, and it has a bendable screen. On the other hand, the 27QHD240 has a more ergonomic stand that you can remove, so you can mount the display if you choose to. The 45WQHD240 gets brighter in SDR, but other than that, the monitors are similar.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
