Introduction

The Acer KG251QF 144Hz gaming monitor is a gorgeous ultra-slim display with a rapid 1ms response time speed, AMD FreeSync, and many more useful gaming features.

It should not be confused with the Acer KG251Q which is the 75Hz model.

Also, note that there’s a 240Hz model dubbed as the Acer KG251QDbmiipx while the full name of our 144Hz monitor in this review is the Acer KG251QFbmidpx.

Image Quality

The Acer KG251QF features the standard 24.5″ TN panel with a peak luminance of 400-nits, a 1,000:1 contrast ratio, a 1080p resolution, a 1ms response time speed, a 144Hz refresh rate, and the sRGB color gamut.

The Full HD resolution won’t give you a particularly eye-catching image quality, but it offers a decent amount of details and screen space.

More importantly, it’s not demanding to drive, so it will be easier on your GPU to push the frame rate all the way up to 144FPS and beyond.

As it’s common for TN panels, the viewing angles are narrow and cause the image to shift in color, contrast, and brightness when you’re looking at the screen from skewed angles.

Furthermore, the colors won’t be as vibrant and accurate as they are on IPS and VA panels, but if you want the fastest pixels for competitive gaming, it’s a fair trade-off.

The Acer KG251QF screen is flicker free and there’s a low blue light filter, so you can game for hours without having to worry about eye fatigue or headaches due to screen flickering.

Performance

Moving on, the Acer KG251QF input lag is only ~5ms which along with the rapid 1ms response time speed and 144Hz refresh rate make this monitor fit for professional fast-paced gaming.

Thanks to its quick response time, there is next to none ghosting and motion blur caused by fast moving objects allowing you to focus on your target without distractions.

Additionally, the 144Hz refresh rate provides you with more than twice as many frames than a regular 60Hz display which makes motion more fluid and smooth.

Features

In the OSD (On-Screen Display) menu, you will find many useful gaming features including ‘Aim Point’ customizable crosshair overlays.

You will also find ‘Black Boost’ which increases visibility in darker games by manipulating the gamma curvature.

Next, there’s the Overdrive setting for the response time adjustments and ‘RefreshRateNum’ which allows you to track the monitor’s refresh rate performance.

Finally, there are eight picture presets available including Action, Racing, Sports, ECO, Graphics, Movie, Standard, and User.

AMD FreeSync

AMD FreeSync is supported with a wide 30-144Hz dynamic range, so if you have a FreeSync-compatible GPU you can unleash the full potential of the Acer KG251QF monitor.

In short, FreeSync allows the monitor to change its refresh rate according to the frame rate of the GPU which completely removes screen tearing and stuttering without extra input lag.

If your framerate drops below 30Hz/FPS, the LFC (Low Framerate Compensation) technology kicks in and doubles the frame rate in order to maintain smooth performance.

You can use the monitor with an NVIDIA card too, but not the variable refresh rate technology.

Design & Connectivity

The Acer KG251QF design consists of ultra-thin and glossy black plastics. Unfortunately, the stand is tilt-only but you can remove the base and mount the screen on a third-party stand using 100 x 100mm VESA pattern.

Connectivity includes an HDMI, a Dual-Link DVI, and a DisplayPort. Keep in mind that the HDMI port of the Acer KG251QF maxes out at 120Hz. There are also two 4W speakers and a headphones jack available.

Price & Similar Monitors

The Acer KG251QF price is $245 MSRP though it’s unknown when the monitor will be available in the US.

If you are looking for a similar monitor, be sure to check out the AOC G2590PX and the AOC G2460PF.

Conclusion

Overall, the Acer KG251QF is decent 24.5″ 1080p 144Hz 1ms gaming monitor; thanks to its wide FreeSync range – it’s ideal for AMD users.

Moreover, due to its thin bezels and affordable price, it’s a great display for a multi-monitor gaming setup.
