Bottom Line

The AOC G2590FX offers stunning performance for fast-paced gaming thanks to its quick response time speed, low input lag, and 144Hz refresh rate. It also features both FreeSync and G-SYNC support with a wide dynamic range and plenty of extra useful gaming features.



There are numerous 24″-25″ 1080p 144Hz 1ms gaming models available which can certainly make choosing the right one a bit overwhelming.

The AOC G2590FX, however, plays it safe and gives you everything you need for competitive gaming at the right price.

You get AMD FreeSync as well as G-SYNC compatibility with a wide dynamic range, low input lag, quick response time, and a high refresh rate.

Image Quality

The AOC AOC G2590FX 144Hz gaming monitor is based on a newer 24.5″ TN panel made by AU Optronics, as opposed to the older 23.6″-24″ TN models.

Besides getting a slightly bigger screen, you get a higher peak brightness of 400-nits as well as slightly better viewing angles and color performance.

Now, the colors are still not as good as they are on IPS or VA panel displays, but they are noticeably richer in comparison to the older TN panels.

The AOC G2590FX TN monitor covers 96% of the sRGB color gamut and supports 8-bit color via dithering (6-bit + FRC).

The 170°/160° viewing angles still cause the image to shift in color, contrast, and color when you look at the screen from skewed angles, but for gamers, this isn’t particularly concerning anyway.

With Full HD resolution, you get a decent pixel density with crisp details, sharp text, and a fair amount of screen real estate. What’s more, it makes reaching 144FPS (Frames Per Second) significantly easier on your PC rig than WQHD.


Moving on to the performance, the AOC G2590FX input lag is impressively low and amounts to only ~4ms. So, even professional gamers won’t be able to notice any delays.

The response time speed of 1ms is another aspect hardcore gamers will appreciate. In fast-paced games such as first-person shooters and racing games, there’s minimal motion blur and ghosting behind fast-moving objects.

Add all that to the monitor’s 144Hz refresh rate, and you get everything you need for a responsive and enjoyable gaming experience.

Finally, the AOC G2590FX 1080p display doesn’t use PWM (Pulse-Width Modulation) to regulate brightness meaning that it’s flicker-free. If you are sensitive to screen flicker, you have nothing to worry about.

Using the joystick placed at the back of the monitor, you can easily navigate through the OSD (On-Screen Display) menu and adjustments.

Pressing the joystick up when not in the menu allows you to swap input sources. Pressing it down places a red ‘Dial Point’ fixed crosshair while pressing it to left opens the ‘Game Mode’ presets (FPS, Racing, RTS, and three customizable Gamer profiles).

Other gaming features include AOC Shadow Control and Game Color, which allow you to alter gamma and color saturation respectively to make certain objects in video games more visible or vibrant.

You will also find ‘Low Input Lag,’ which further decreases input lag by bypassing certain image processing. Lastly, there are four Overdrive options for the response time speed: Off, Weak, Medium, and Strong.

If you have an Adaptive-Sync compatible graphics card by AMD or NVIDIA (GTX 10-series, RTX 20-series, or newer), you can enable variable refresh rate which will allow the AOC G2590FX to change its refresh rate dynamically.

In other words, the frame rate between the GPU and the refresh rate of the display will be synchronized, thus removing screen tearing and stuttering but without introducing input lag like VSYNC does.

The AOC G2590FX variable refresh rate range is 30-144Hz/FPS which is surprisingly good as on most FreeSync gaming monitors, the VRR range is usually 40-144Hz or 48-144Hz.

Moreover, when your FPS rate dips below 30, the display will run LFC (Low Framerate Compensation) which multiplies the refresh rate according to the frame rate in order to minimize screen stutter until your FPS rate recovers.

Design & Connectivity

The design of the AOC G2590FX monitor is clearly aimed at gamers with its red accents, which, thankfully, aren’t too aggressive.

Alas, the stand is tilt-only (-3.5°/21.5°), but you can mount the screen on a third-party stand via the 100x100mm VESA pattern. Further, the design has ultra-thin matte-black bezels and a cable management bracket.

Connectivity options include DisplayPort 1.2, two HDMI 1.4 ports, VGA, and a headphones jack. FreeSync works over both DP and  HDMI up to 144Hz whereas G-SYNC works over DisplayPort only.

Price & Similar Monitors

The AOC G2590FX price is around $200. If you mostly play competitive FPS games, it’s a great budget display. However, for the best results, consider investing ~$50 more in a 240Hz display such as the Acer XF250Q – if your PC can sustain 240FPS at 1080p.

In case you’re not a hardcore FPS gamer, but would still like the extra responsiveness 144Hz provides, check out the AOC 24G2 with an IPS panel and the AOC C24G1 with a curved VA panel.

Both of these models are more budget-friendly and offer better image quality, but they don’t have as fast response time. Their input lag is just as low, so you won’t be able to feel any delays, but some motion blur (on the 24G2) and black smearing (on the C24G1) will be perceptible.

On Amazon, you will also find the AOC G2590PX which is the same monitor but with a fully ergonomic stand, built-in speakers, and a quad-USB 3.0 hub for $30 extra.

Alternatively, depending on your region, you might want to take a look at the Acer KG251QF and the HP Omen 25 which are based on the same panel as the G2590FX/PX.


The AOC G2590FX offers an appealing set of features and specifications for the price if you’re looking for a high-quality monitor for competitive gaming.

It has a wide variable refresh rate range, G-SYNC compatibility, quick response time, low input lag, and lots of additional gaming features.

If you’re not all that competitive, there are better alternatives available.
