ASUS PG259QN Review: 1080p 360Hz 1ms IPS G-Sync Monitor

One of the first 360Hz gaming monitors, the ASUS ROG Swift PG259QN comes with amazing features such as rapid response time, NVIDIA G-SYNC with ULMB and low input lag. These features would surely provide exciting and enjoyable competitive gaming experience.

For average gamers, however, they might not love this monitor as it only comes with low 1080p resolution and is offered at a higher price. However, if you are a hardcore FPS player, then this display is perfect for you.

Image Quality

This gaming monitor is based on IPS panel by AU Optronics. It comes with specifications:

  • · 1000:1 contrast ratio
  • · 10-bit color depth support via dithering
  • · 400-nit peak brightness
  • · Standard 99% sRGB color gamut
  • · Accurate and consistent colors with wide 178 degree viewing angles

In comparing ASUS PG259QN and LG’s IPS panels, LG only has a contrast ratio of 700:1 up to 800:1. ASUS on the other hand comes with a range of 1000:1 up to 1200:1. This means, you will not notice or experience any grayish color on ASUS. This monitor is priced at $700 for 1920 x 1080 monitor which is a bit quite expensive for low resolution. Other than that, this 1080p would look amazing on 24.5” sized monitor due to its pixel density of 90 PPI. Its HDR on the other hand is supported too. However, due to the lack of wide color gamut and local dimming, HDR content would not look better.

This monitor could provide IPS glow. Though that is the case, all IPS monitors suffer this glowing of corners. Do not worry as it is manageable.


Changing from 144Hz to 240Hz is not noticeable nor is it a game changer for gamers. However, for those who are seriously competing in games, they could often go for the faster and more responsive game display.

If you are going to 360Hz from 240Hz, you will not see much difference just as you going from 144Hz to 240Hz. It would be better to get something that you will notice and feel and if you want to experience that, we suggest going from 144Hz to 360Hz.

The ASUS PG259QN comes with fast pixel response time speed. This means, you will no longer have to experience ghosting. Aside from that, there are three response time overdrive modes – Off, Normal and Extreme.

The off mode is not fast. Extreme on the other hand is too much overshoot. Normal is perfect and comes with minor pixel overshoot. This means, you will not have to worry about your frame rate. The normal mode will work best on G-SYNC. This will eliminate any screen tearing and stuttering. ASUS PG259QN also has low input lag of 1ms.


If your monitor display does not use G-SYNC you could use NVIDIA ULMB. This would reduce ghosting as well. Take in mind that you could not activate G-SYNC as it could only work on 144Hz or 240Hz. Here are a few of ASUS PG259QN features:

  • Brightness is reduced when ULMB is active
  • Smoother motion clarity
  • Image is clearer at 144Hz than at 240Hz.
  • GamePlus – custom crosshairs, refresh rate tracker, timers
  • GameVisual – pre-calibrated picture presets
  • Dark Boost
  • Directional joystick at the back of the monitor
  • Four additional hotkeys
  • ROG logo with RGB lighting
  • Design & Connectivity
  • Versatile ergonomics
  • 120mm height adjustment
  • +/-25-degree swivel, -5/20-degree tilt, 90-degree pivot and 100x100mm VESA mount
  • Bezels are ultra-thin
  • Has an anti-glare coating which could eliminate reflection
  • Connectivity options: DisplayPort 1.4, HDMI 2.0, headphones jack and dual-USB 3.0 hub
