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 G2590PX, however, plays it safe and gives you everything you need for competitive gameplay at the right price.

You get AMD FreeSync with a wide dynamic range, a fully ergonomic design with thin bezels, a new TN panel, and more.

Image Quality

The AOC AOC G2590PX 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 G2590PX TN panel 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 plenty 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 G2590PX 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 by refreshing the image more than twice as fast the standard 60Hz displays, you’ll have everything you need for a responsive and immersive gameplay.

Finally, the AOC G2590PX 1080p display doesn’t use PWM (Pulse-Width Modulation) to regular 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.

AMD FreeSync

If you have a Free-Sync compatible GPU by AMD, you can enable variable refresh rate which will allow the AOC G2590PX 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 G2590PX FreeSync 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 doubles the frames in order to avoid screen stutter until your FPS rate recovers.

In case you have an NVIDIA card, you can still use the monitor, but not the variable refresh rate. To get variable refresh rate on NVIDIA GPU, you will need a G-SYNC monitor.

Design & Connectivity

The design of the AOC G2590PX monitor is clearly aimed at gamers with its red accents which thankfully, aren’t too aggressive.

You get full ergonomic adjustments including -3.5°/20° tilt, +/- 45° swivel, up to 130mm height adjustment, and 90° pivot clockwise as well as 100 x 100mm VESA mount pattern.

Furthermore, the design has ultra-thin matte-black bezels and a cable management bracket.

The connectivity options are quite generous and include a DisplayPort, two HDMI 1.4, a VGA, a headphones jack, two 2W integrated speakers, and a quad-USB3.0 (one USB with quick-charging) hub. FreeSync works over the HDMI ports as well.

Price & Similar Monitors

The AOC G2590PX price is around $290 which is slightly more than an average 24″ 1080p 144Hz 1ms gaming monitor, but if you want the premium features, it’s worth it.

Alternatively, you may be interested in the AOC G2460PF which for only $200 offers most of the same features including a wide FreeSync range.

Also worth checking out is the LG 24GM79G if you want a 144Hz monitor with the motion blur reduction technology.

On Amazon, you can also find the AOC G2590FX which is the same monitor but without the ergonomic stand and USB ports; the AOC G2790PX is the 27″ model while the AOC G2590VXQ is the 75Hz version of the monitor.


The AOC G2590PX 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 FreeSync range, a quick response time, a high refresh rate, and a flawless input lag performance, but unfortunately lacks motion blur reduction via backlight strobing.

Thanks to its newer TN panel, you get decent colors, slightly better viewing angles performance, and a tad bigger screen in comparison to the older TN models.

Finally, its extra gaming features and versatile design are the icing on the cake.
