AOC G2590FX Review: 1080p 144Hz 1ms G-SYNC Compatible FreeSync Gaming Monitor


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

The AOC G2590FX, however, plays it safe and gives you everything you need for competitive gameplay 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 but 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 system rig than WQHD.


Moving on to the performance, the AOC G2590FX input lag is impressively low and amounts to only ~4ms; it’s one of the fastest displays we’ve ever tested which will certainly appeal to professional gamers.

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.

In addition to the monitor’s 144Hz refresh rate, which refreshes the image more than twice as fast than the standard 60Hz displays, you’ll have everything you need for a responsive and immersive gameplay.

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 on the rear 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 opens up customizable ‘Dial Point’ crosshair overlays, and pressing it to left opens ‘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 values in order to make certain objects in video games more visible.

You will also find ‘Low Input Lag’ setting 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 and RTX 20-series), 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 gaming monitors, the FreeSync 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 avoid 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 at least you can mount in on a mounting arm/wall via 100 x 100mm VESA pattern. Further, the design has ultra-thin matte-black bezels and a cable management bracket.

Connectivity options include a DisplayPort 1.2, two HDMI 1.4, a 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 ranges from $200 to $250. For $200, you may also want to consider the Acer XFA240 which is a 24″ 1080p 144Hz 1ms gaming monitor with both G-SYNC and FreeSync support. Both are excellent models, so pick according to your budget.

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. Further, there’s the AOC G2790PX which is the 27″ model while the AOC G2590VXQ the 75Hz version of the monitor.

Overall, for the best value for the price, we recommend either the AOC G2590FX or the Acer XFA240. If you’d like a motion blur reduction technology, check out the LG 24GL600F.

Alternatively, depending on your region, you may want to check out the Acer KG251QF and the HP Omen 25 which are based on the same panel as the G2590FX.


The AOC G2590FX offers an alluring 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 plenty of additional gaming features.
