OLED is the best technology for gaming!

Alongside the LG UltraGear 27GR95QE and Asus ROG Swift PG27AQDM, Corsair also entered the OLED monitor market this year. First with the impressive Corsair Xeneon Flex and its flexible 45-inch panel, then with a more classic 27-inch diagonal screen, which tries to provide the best possible gaming experience with its OLED panel and its 240 Hz.

Still impossible a few months ago, gaming on a standard size Oled monitor is now a reality. Three references have been launched for 2023, including the Xeneon OLED, which allows Corsair to expand its catalog of gaming screens even further. With its panel supplied by LG Display and its long technical sheet, this Xeneon 27QHD240 OLED is trying to position itself as one of the best gaming screens in its category.

Design and ergonomics

Very simple in its expression, the Xeneon 27QHD240 OLED is nonetheless a monitor with an intelligently designed design and meticulous finishes. We quickly notice that we are dealing with an Oled monitor, the thin thickness of the slab and the borders are not deceiving.

We have the right to a relatively compact foot made of metal, the part associated with the screen is quite wide and leaves a space to pass the cables. These connect perpendicular to the screen, something that greatly facilitates the process with easily accessible connectors.

On the ergonomics side, Corsair offers us a monitor with quite classic adjustments, nothing to say on this point. The screen adjusts in height, tilts forwards and backwards, adjusts to the right and left and benefits from a portrait mode, all the usual options in short.


Corsair has opted for a completely complete connection with two HDMI 2.1 ports, a DisplayPort 1.4, as well as a USB-C port with Display Alt Mode support and power supply up to 65 W. To this is added a second USB-C port which powers a hub made up of 4 USB 3.1 ports.

Finally, note that simplicity is essential, firstly thanks to the positioning of the connectors, to the support which allows all our cables to pass, but also in terms of ergonomics with an OSD which appears when we approach the hand of the joystick located under the screen. On the other hand, the OSD itself remains relatively basic but nevertheless includes all the configuration options that can be expected from such a screen.

Performance: nothing better than Oled

Suffice to say, the Corsair Xeneon 27QHD240 OLED is very close to the LG UltraGear 27GR95QE that we tested a few weeks ago. We weren’t able to test the two screens next to each other, but it’s a safe bet that the image rendering and fluidity are quite similar. Of course, we are slightly biased by having had LG’s first in our hands, with a “Wow” effect which was undoubtedly more marked on the first. There is, however, no reason not to be enthusiastic about the experience this Xeneon monitor offers.

The improvements are huge in every respect compared to a regular gaming screen, even compared to a Mini-LED model. An OLED monitor like this shows great versatility: regardless of the content or type of use, it is satisfactory in most cases, for working on photos, video, graphics, for consuming multimedia content, and of course for gaming. On this last point, it seems clear and clear that Oled monitors of this type represent the future.

Their price is certainly still too high, but the image displayed and the performance of a screen like the Corsair Xeneon 27QHD240 OLED are breathtaking. The impression of fluidity first! We used to play on OLED televisions which did not allow us to go beyond 120 Hz; these already offered many advantages despite this limit and, inevitably, their imposing diagonal. With a 27-inch OLED screen clocked at 240 Hz, a game will never have seemed so fluid to you. Admittedly, it is still necessary to ensure that the graphics card can follow this QHD definition, if this is the case it is certain that you will notice a huge difference between this Oled monitor and an LED monitor with similar capabilities.

Image quality

As is almost always the case with Oled, we get excellent results with the probe. Unsurprisingly, the “Creator” image mode offers the most faithful image. The color temperature is slightly below 6500K, but you don’t really notice that in the picture. The colorimetry is perfectly respected, with an average Delta E of only 2.49, a sign that the factory calibration of this model has been particularly careful. The brightness in SDR does not exceed 400 cd / m², it is nevertheless sufficient, especially since the coating of the slab makes it possible to erase the most important reflections.

The Corsair Xeneon 27QHD240 OLED performs very well with HDR signals. The brightness remains contained, with a luminous peak at 730 cd / m² in the best case, on windows of 1 and 2%. On larger windows (at 10%), the brightness is more around 600 cd/m². This is much less than what a Mini-LED monitor like the AOC Agon Pro AG274QXM offers, however the dynamism is clearly not the same thanks to the deep blacks of which the Oled panel is capable. Once again, the Delta E is perfectly respected in HDR with an average value of 2.15, in other words that chromatic drifts are rare.

Power consumption

OLED monitors, as is the case with TVs that use this display technology, tend to have higher than average power consumption. This is once again the case with this monitor from Corsair. Its relative consumption is indeed 116 W/m².

Corsair Xeneon 27QHD240 OLED price and availability

Displayed at €1,149 on the Corsair store, the Xeneon 27QHD240 OLED is placed between the monitor from Asus and that from LG in terms of price. The price remains high for a 27-inch diagonal screen, the competition is also starting to get tough since AOC has just announced the imminent release of its AGON PRO AG276QZD, a 27-inch QHD Oled monitor, against the sum of 999 euros.
