ASUS VG259Q Review: 1080p 144Hz FreeSync IPS Gaming Monitor

Asus Vg259q Review 2020

Bottom Line

The ASUS VG259Q offers remarkable image quality and smooth performance with plenty of useful gaming features.



The ASUS VG259Q is a 1080p 144Hz IPS gaming monitor with a rapid pixel response time speed and certified G-SYNC compatibility which ensures stunning colors as well as fluid performance.

Image Quality

Based on an AHVA (IPS) panel by AU Optronics, the ASUS TUF VG259Q monitor features wide 178° viewing angles, a 400-nit peak brightness, a static contrast ratio of 1,000:1, and dithered 8-bit color depth support (6-bit + 2-bit FRC).

The use of dithering shouldn’t concern you as most IPS panels at this price range use it for 8-bit color. There’s no noticeable difference in comparison to true 8-bit panels nor any visible artifacts such as pixel inversion.

Further, the monitor’s color gamut is 72% NTSC, which is equivalent to ~99% sRGB. The colors are accurate, consistent, and vivid.

However, out of the box calibration isn’t great (depending on the particular unit of the monitor).

For the optimal image quality, calibration is required. If you want the best image quality right away, you can use the provided sRGB picture preset for precise color reproduction.

Note, however, that you cannot adjust the monitor’s brightness while using the sRGB preset, which is a shame as for some users, the picture may be too bright in this mode.

The 1080p resolution results in a decent pixel density of roughly 90 PPI (pixels per inch) on the 24.5″ viewable screen of the ASUS VG259Q.

This means that there’s a decent amount of screen real estate available and that text and details are sharp and clear.

Some minor IPS glow, and backlight bleed is visible, as expected from an IPS panel display.

This varies between different units of the monitor, but in most cases, it’s only noticeable in dark rooms with pitch-black backgrounds on the screen, and it’s completely tolerable.


Asus Vg259q Vs Aoc 24g2

While the picture quality of the ASUS VG259Q IPS monitor is nothing extraordinary (it’s good, but nothing special considering its price), its performance is where the things start to heat up.

With a pixel response time speed of 3ms (GtG), there is as little motion blur and trailing behind fast-moving objects as possible for a 144Hz monitor.

Now, to get the specified 3ms response time, you’d need to set the ‘TraceFree’ overdrive option to 100; it scales from 0 to 100 in increments of 20.

However, that introduces a lot of pixel overshoot. We recommend setting it to 40 or 60 as that way you won’t get any overshoot nor ghosting.

Alternatively, you can use the Extreme Low Motion Blur (ELMB) technology to get 1ms MPRT (Moving Picture Response Time).

This technology further eliminates visible ghosting by backlight strobing and provides CRT-like motion clarity. However, it can only be used at fixed refresh rates of 100Hz, 120Hz, or 144Hz.

Additionally, it reduces the monitor’s maximum luminance while active, but with a 400-nit peak brightness, the monitor is more than bright enough even with this feature enabled.

The ASUS VG259Q supports AMD FreeSync with a 48-144Hz variable refresh rate (VRR) range and LFC (Low Framerate Compensation) support.

NVIDIA also certifies it as G-SYNC compatible, so you will be able to use FreeSync with compatible NVIDIA cards (GTX 10-series or newer) over DisplayPort.

FreeSync allows the monitor to change its refresh rate according to GPU’s frame rates, thereby eliminating screen tearing and stuttering without adding a hefty input lag penalty as VSYNC does.

Note that ELMB and FreeSync cannot be enabled at the same time on this monitor.

Finally, the ASUS VG259Q input lag amounts to ~4ms, which makes for imperceptible delay at 144Hz.


Asus Vg259q Vs Acer Vg240y P

The OSD (On-Screen Display) menu of the monitor is user-friendly and easy to navigate thanks to the 5-way joystick placed at the back of the monitor.

In addition to the joystick, there are four buttons that you can use to swap between input sources quickly, GamePlus and GameVisual features, and power on/off.

The GamePlus feature consists of on-screen timers, trackers, and crosshairs, while GameVisual offers pre-calibrated picture presets (Scenery, Racing, Cinema, RTS/RPG, FPS, sRGB, and MOBA).

You’ll also find three profiles to save/load your settings as well as other standard picture adjustment tools such as contrast, brightness, sharpness, color temperature, saturation, etc.

The monitor has a flicker-free backlight and an integrated low-blue light filter, which ensures a comfortable viewing experience on your eyes.

Lastly, there’s the Shadow Boost feature, which improves visibility of objects in shadows by altering the gamma curvature.

Design & Connectivity

The design of the ASUS VG259Q monitor features a fully ergonomic stand with up to 130mm height adjustment, +/- 90° swivel, 90° pivot, -5°/33° tilt, and 100x100mm VESA mount compatibility.

ASUS applied a peculiar image filter to the screen, which makes the text seem a bit fuzzy and blurry. Some users might find it distracting, while others might not be bothered by it all, just something to keep in mind.  

Connectivity options include two HDMI 1.4 ports, a single DisplayPort 1.2 input, a headphones jack, and dual 2W integrated speakers. All three inputs support 1080p up to 144Hz.

Price & Similar Monitors

The ASUS VG259Q price amounts to ~$280 which is a bit steep for a 1080p 144Hz display.

We also recommend checking out Acer’s models which use the same panel, such as the Acer XB253QGP without the image filter that ASUS used for their VG259Q model.

For $100 less, you can get the AOC 24G2 1080p 144Hz IPS monitor which even has a wider color gamut of 126% sRGB. Plus, due to its smaller screen size, it has a bit higher pixel density (92.56 PPI) for slightly sharper text and details.

The AOC 24G2, however, doesn’t have as fast pixel response time.

So, is the quick response time worth the extra $100? Well, if you’re a casual gamer, it’s not.

Then again, if you’re a serious FPS gamer, you can just invest ~$40 extra and get the ASUS VG259QM model with a 280Hz refresh rate and a faster 1ms GtG response time speed.

Overall, the ASUS VG259Q is an extraordinary gaming monitor. Although it’s a bit expensive, if you want both great colors and swift response time, it’s the best 1080p 144Hz option currently available.
