Controls and OSD

The Corsair Xeneon 27QHD240 OLED uses an interesting control scheme. A single 4-way button is used to navigate the OSD. The main part of the OSD is opened by clicking the button, but you can also pull it in either direction to access four quick menus: brightness, factory picture profiles, input selection, and audio output volume.


The monitor is equipped with a proximity sensor, which detects your palm getting close to the buttons and activates a menu showing the exact positions of the aforementioned 4-way button, as well as two other buttons placed below the screen: a power button and an input source button. The sensor is calibrated well; it never triggers on accident, but also never fails to bring up the appropriate menu when you go to reach the button(s).

The OSD is split into the following sections: Picture, PIP/PBP, OSD Setting, System Setting, Audio, Input Source, and Information.


The Picture menu is where you'll find factory picture presets (Standard, Movie, Text, sRGB, Creative, Game), as well as brightness, contrast, sharpness, color temperature, gamma, and saturation controls. Interestingly, the second part of the menu also has a refresh rate overlay toggle and virtual crosshairs. Here you can pick between the three most popular crosshair types - dot, cross, and angle – and have them displayed in red or green color. With this being an OLED monitor, I'd advise against using virtual crosshairs or refresh rate overlays, as these are the typical types of content that are prone to burn-in if used regularly.


In the PIP/PBP menu, you can turn on Picture-in-Picture and Picture-by-Picture modes, select secondary window position and source when using PiP, quickly swap the sources, and choose the audio source.


The OSD Setting menu lets you change the OSD language, transparency, and duration.


The System Setting menu is the second most important one. Here you can toggle adaptive synchronization, manually start the image retention refresh, and control two important burn-in-preventing features: Orbit and Brightness Stabilizer. Orbit is a feature that automatically shifts the image by a couple of pixels while you're using the monitor. This is a way to fight against static UI elements. I usually find this feature distracting and undesirable, but I barely noticed it on the Corsair Xeneon 27QHD240 OLED. Corsair found a good balance between how often the picture shifts, and by how much. There are also no issues with some Windows UI elements shifting away from sight, which I ran into on several previous occasions, for example, while testing the absurd INNOCN 48Q1V. As for the Brightness Stabilizer, it essentially deactivates the Auto Brightness Limiter (ABL), to prevent oscillations in picture brightness depending on the content currently being displayed, but at the expense of overall brightness. If you find ABL annoying, which many of us do, the Brightness Stabilizer is here to help with that. In the picture quality section of this review I'm discussing the Brightness Stabilizer feature in more detail, along with some measurements, so make sure to check that out to find out if it is a viable way of eliminating ABL on the Xeneon 27QHD240 OLED.


The Audio, Input Source, and Information menus are self-explanatory, so there's not much to add here. All I can say is that you should keep an eye on the firmware version of the monitor (found at the bottom of the Information menu) because future firmware updates could bring further improvements to its picture quality, especially brightness. One such update was V103, which brought a 30% increase in brightness when using Brightness Stabilizer, which is actually a huge upgrade for the Corsair Xeneon 27QHD240 OLED. More on that in a moment.
