BenQ Zowie XL2540 Review: 240Hz FreeSync G-SYNC Compatible Gaming Monitor


Looking for a 240Hz gaming monitor for the smoothest and most responsive competitive gameplay experience?

The BenQ ZOWIE XL2540 is an excellent model with plenty of additional features you might find useful.

Image Quality

Just like all 240Hz 1080p gaming monitors available, the BenQ XL2540 is based on a TN (Twisted Nematic) panel with a 400-nit peak brightness, a 1,000:1 contrast ratio, 8-bit color depth, and a quick 1ms response time speed.

Its panel is no different than the rest of TN panels when it comes to the viewing angles and color reproduction.

The viewing angles are 160°/170° which means that the picture will shift in color, contrast, and brightness if you look at it from skewed angles. So, as long as you’re sitting in front of the screen, this is not a big issue.

In comparison to the other panel technologies such as IPS and VA, the TN panels have the worst color quality, but they also have the fastest response time speed.

So, if you care more about the performance than the image quality, it’s a fair trade-off.

The panel does cover a decent amount of the sRGB color space (~92%) but calibration is required for the optimal picture quality.

Lastly, 1080p resolution provides a satisfactory image quality in terms of pixel density, you get crisp details and a fair amount of screen space.

More importantly, reaching higher framerates will be easier on your GPU and CPU as 1080p is not very demanding.


The BenQ ZOWIE XL2540 input lag performance is impressive at just below 4ms.

Moving on, the response time speed is remarkable as well; the pixels take ~1ms to change from one shade of gray into another which is quick enough to eliminate almost all ghosting of fast-moving objects.

For the best response time performance, set the overdrive (AMA – Advanced Motion Acceleration) setting in the OSD (On-Screen Display) menu to ‘High’.

Gaming at 240Hz does feel smoother than gaming at 144Hz, but the difference isn’t nearly as noticeable as it’s between 60Hz and 144Hz.

In addition, you can enable backlight strobing which can further remove motion blur and ghosting in fast-paced games.

To enable this feature, however, you’ll need to open up the BenQ ZOWIE XL2540 service menu as it’s not available in the OSD.

In order to open the service menu, you need to turn off the monitor first and then hold the fourth monitor hotkey from the left and simultaneously press the power button to turn on the display.

Now, the fourth hotkey will open up the service menu instead of the OSD. To reverse this, simply turn the monitor off and on again. In the service menu, you’ll find the Blur Reduction feature and its intensity settings with the minimal frequency being 100Hz and the maximum 240Hz.

Other gaming features include AMD FreeSync with a 48-240Hz range and LFC support. This technology allows the monitor to change its refresh rate dynamically if connected to a compatible AMD graphics card.

In turn, all screen tearing and stuttering is eliminated with virtually no input lag penalty. However, FreeSync only works with AMD cards and cannot be active at the same time as the motion blur reduction technology.

Update: FreeSync also works without any issues when using a compatible NVIDIA G-SYNC graphics card. The monitor has been added to the list of G-SYNC compatible gaming monitors certified by NVIDIA.

Additionally, you will find the Color Vibrant feature which is basically color saturation with 0-20 values and Black eQualizer which brightens up the dark areas in video games for better visibility of objects in the shadows.

Lastly, with the BenQ ZOWIE XL2540, you also get the S. Switch external device that you can use to navigate through the OSD settings and quickly change picture presets including two FPS modes, RTS, Movie, Standard, and three customizable profiles.
