ASUS XG248Q Review: 1080p 240Hz G-SYNC Compatible FreeSync Gaming Monitor With Backlight Strobing


The ASUS ROG Strix XG248Q is a 23.8″ 1080p 240Hz gaming monitor aimed at professional and hardcore gamers.

What makes this 240Hz model stand out from the rest of similar monitors is that it supports FreeSync, it’s G-SYNC compatible, and offers backlight strobing up to 240Hz – all that for a very appealing price.

Image Quality

Unlike the more popular 24.5″ 1080p 240Hz models, the ASUS XG248Q uses a 23.8″ panel by Innolux which offers slightly sharper and clearer details thanks to its higher pixel density (pixel-per-inch ratio).

Although it features the same specs including dithered 8-bit color depth (6-bit + FRC), 400-nit peak luminance, and 1,000:1 contrast ratio, the color and contrast performance is a bit weaker on the ASUS ROG Strix XG248Q display.

The difference, however, is negligible after considering the superior performance the XG248Q offers in comparison to the 24.5″ variants.


Thanks to its imperceptibly low input lag (~4ms) as well as rapid 1ms response time and 240Hz refresh rate, the ASUS ROG Strix XG248Q monitor delivers an impeccable and flawless performance in fast-paced games.

Further, you can enable the ASUS ELMB (Extreme Low Motion Blur) motion blur technology which via backlight strobing provides CRT-like motion clarity.

Now, the backlight strobing frequency of most 240Hz monitors maxes out at 144Hz whereas the XG248Q goes all the way to 240Hz.

A few more 240Hz displays (BenQ ZOWIE XL2546 and the LG 27GK750F) can also strobe the backlight at 240Hz, but the ASUS XG248Q is the only 24″ model capable of doing this.

Note that you can also enable ELMB at 120Hz, 144Hz, and 200Hz in addition to 240Hz; set it to the refresh rate that’s the closest to your frame rate for minimal strobe crosstalk.

In addition to having six levels of response time overdrive (from 0 to 6) as well as both FreeSync and G-SYNC support, you will certainly be able to tweak the perfect settings to match your preferred gaming experience/gameplay style with this gaming monitor.


ASUS’ standard gaming features including GamePlus and GameVisual are also available on the ASUS XG248Q 240Hz gaming monitor.

These features include customizable on-screen timers, crosshairs, and an FPS counter as well as pre-calibrated picture presets (Racing, RTS/RPG, FPS, MOBA, Scenery, User, Cinema, sRGB) and four customizable profiles you can edit/save.

Additionally, the monitor offers AuraSync which consists of customizable RGB LED lighting that you can synchronize with the rest of AuraSync-compatible hardware as well as with on-screen content in compatible games.

The monitor is flicker-free, has a low-blue light filter, and features a user-friendly OSD (On-Screen Display) menu that can be easily navigated via its 5-way joystick. You will also find three gamma presets (1.8, 2.2, and 2.5) and other standard adjustments.

Lastly, you get ASUS’ DisplayWidget software where you can customizable all your settings and presets in a desktop application.

Design & Connectivity

Asus Xg248q Review

The design is sturdy and versatile with up to 100mm of height adjustment, 90° pivot, +/- 50° swivel, -5°/20° tilt, and 100 x 100mm VESA mount compatibility.

Beneath the base of the monitor, there’s the ROG logo light projector which comes with two different logo covers and one that’s customizable.

Connectivity options include two HDMI 2.0, a DisplayPort 1.2, a dual-USB 3.0 hub, and a headphones jack.

FreeSync works over both HDMI and DisplayPort with a 40-240Hz variable refresh rate range whereas G-SYNC (requires at least 417.71 WHQL drivers and GTX 10-series or RTX 20-series NVIDIA GPUs) works over DisplayPort only, with the same range.

Price & Similar Monitors

The ASUS ROG Strix XG248Q price is around $350 which is a standard price for a 240Hz monitor. However, considering that this model is G-SYNC compatible and offers backlight strobing up to 240Hz, we find it to be the best 240Hz monitor for the money.

While the 24.5″ models may have a slightly bigger screen and somewhat better color/contrast, the performance of the XG248Q is much better which is what competitive gamers prefer anyway.


The XG248Q is also available as a 24.5″ variant, the ASUS ROG Strix XG258Q. Note that the XG248Q is actually the newer model, not vice versa.

In comparison, the XG258Q doesn’t have a USB hub and its motion blur reduction feature maxes out at 144Hz yet it’s more expensive. The ASUS XG258Q is also G-SYNC compatible.


If you want the best performance in fast-paced video games, the ASUS XG248Q is our #1 recommendation.

It gives you all the assets the other models have, and it does it for a more budget-friendly price. Plus, you get a wide range of features to tinker with including both FreeSync and G-SYNC, MBR up to 240Hz, and six overdrive options, among other things.
