OSD Setup & Calibration
Pressing any of the XB252Q’s control buttons or the joystick brings up a quick menu. The first two slots are programmable, while the third is an input selector. A second click of the joystick brings up the full OSD.
The XB252Q has eight picture modes, but only User allows for calibration. However, once your settings are dialed in, they can be saved to one of the three gaming modes, which is a nice feature. The full OSD starts off with luminance sliders, a Blue Light feature, Dark Boost for low-end detail rendering, and Adaptive Contrast, which will clip shadow and highlight areas of the image while increasing perceived contrast. Making any change whatsoever will switch the picture mode to User.
The Color menu has four gamma presets ranging from 1.9 to 2.5 plus a Gaming option that looks even darker than 2.5. 2.2 measured closer to 2.4 in our tests. You also get four color temp settings plus an adjustable User mode. The sliders are very precise and start at center-range, which allowed us to dial in good accuracy without losing too much contrast. The sRGB mode fixes output at 370 nits with slightly visible color and grayscale errors. It doesn’t offer any benefit over the default presets. If you want to manipulate color saturation and luminance, those sliders are available here as well.
The Audio menu has only a volume control that operates on the internal speakers and the headphone output.
The Gaming menu has two overdrive settings. We recommend Normal. The Extreme option causes visible ghosting. It’s grayed out in ULMB mode, so you'll see faint trails behind the fastest moving objects. It’s better to stick with G-Sync, which allows overdrive. ULMB can be used up to 144Hz, and the XB252Q has plenty of output to compensate for the brightness loss. The pulse width can be adjusted over a 100-step range to balance blur-reduction with light levels. The Brightness control can be set independently for each mode. Users of 3D LightBoost will find a variable slider. And novice gamers can turn on one of three aiming reticles.
The OSD menu has multiple language options, a timeout of up to 120 seconds, and a transparency toggle. Refresh Rate Num places a large yellow FPS counter in the upper-right corner of the screen. Your friends and competitors will know your framerates even when standing across the room.
The System menu has an input selector, aspect ratio options, a Deep Sleep power-saving mode, Quick Start (saves power when off), Power LED dimming, and a USB port power setting. The ports can be left on to charge your devices when the monitor is turned off. Hot Key Assignment lets you program the first two control keys for a variety of functions saving you a trip into the OSD.
After dialing in your preferences, you can save them to one of the three gaming modes. And if you need signal info, click on the “i” icon (third key) to view input resolution, refresh rate, and mode (G-Sync, ULMB, or Normal) status. Unlike the Asus ROG monitors, the power LED doesn’t change color to indicate this. That’s a handy feature we’d like to see incorporated into the XB252Q.
Once you set output with the brightness slider, the XB252Q will be in User mode, which means you can alter gamma, color temp, and color saturation to your liking. The native color gamut is the same regardless of mode, so we performed a grayscale adjustment and lowered the contrast control, which is set about 10 clicks too high. Leaving it alone would mean clipped detail in the brightest content and some color inaccuracy too. Out-of-box performance is merely adequate, but a few adjustments will bring the monitor to a good standard. Here are our recommended settings. When you’re satisfied, we suggest saving the settings to one of the gaming modes.
