Crisp, Clear Image Quality

Offering an IPS panel, the ASUS ROG Swift PG27UQ has 178-degree viewing angles and a response time of just 4ms.

The aspect ratio is 16:9, or the standard widescreen aspect ratio that all of the leading titles are taking advantage of when developing their games.

You’ll be able to use this monitor when you’re gaming, working on professional tasks or even rendering high-end animations.

Colors are intense, offering the best of colors in the DCI-P3 and Adobe RGB color space. Adobe’s RGB color space has 99% coverage, while the DCI-P3 color space has 97% color space.

In addition, the display itself is a Quantum-Dot IPS display, which means that accurate color imagery is supported. Therefore, you’ll have realistic color reproduction thanks to the DCI-P3 color gamut far outperforming the color range that is offered through sRGB.

What does this mean in the real world?

You’ll be able to enjoy graphics that utilize the colors that developers and designers chose for leading games.

Crisp, clear and vivid, the color profile will bring better overall graphics to your games.

Everything looks crisper and cleaner thanks to the color profile.

But that’s not the only thing that people are talking about when they mention the ASUS ROG Swift PG27UQ. You’ll also be able to experience:

  • Brightness levels of up to 1,000 nits on HDR and 600 nits for non-HDR
  • 384 dimming zones to dim the backlight as needed during gameplay
  • Contrast ratios that go as high as 50,000:1 for HDR

High-level contrast ratios allow for highlights and shadows that make picture quality stand out. And in gaming, lighting and highlights make or break the experience. You’ll be immersed in the gaming environment like never before.

Then there’s the 4K Ultra HD resolution that offers the industry’s best picture, and all of it is displayed on a 27-inch monitor.

Fast Performance and Customization Options

Gameplay is offered at a refresh rate that is as high as 144 Hz. Smooth and fast, the refresh rate is also supported by two unique sync technologies that allow for the monitor to perform well with even the most intense games. You can find out what cables support 144hz here.


NVIDIA’s G-Sync technology allows for the smooth, fluid gameplay that you want in your video games. G-Sync is responsible for reducing, or eliminating, the following during gameplay:

  • Display stutter
  • Input lag
  • Screen tearing

Games are more fluid, faster and flawless thanks to NVIDIA’s G-Sync.

Aura Sync

Aura Sync is another technology that assists with RGB lighting.

The Aura Sync technology allows for the synchronization of ambient lighting, and this is done when other peripherals and components have Aura Sync enabled.

When gaming for hours, whether stuck in a raid or dungeon on your favorite MMORPG or streaming on Twitch, the monitor’s flicker-free technology will enhance the experience.


ASUS has incorporated what’s called “Ultra-low Blue Light filters” into the monitor. What does this mean? It means that the monitor is built to protect your eyes from the harmful blue light that most monitors produce.

On-screen flickering is also kept to a minimum, allowing you to suffer from less eye strain when playing for hours on end.

The monitor allows for the long gaming experience that advanced gamers enjoy without the immense strain on the player’s eyes or fatigue experienced during gameplay.

If you find yourself getting immersed in a game for hours on end, this is a capability that will allow you to keep playing without the headaches or eye strain involved.

Therefore, there is no need to use gaming glasses to protect your eyes.

Ambient light sensors are built into the monitor and will automatically adjust the panel’s brightness levels.

Lighting effects can be synchronized across the entire ASUS sync experience.

ASUS also offers GameVisual and GamePlus which allow for customizable:

  • On-screen timers
  • FPS counters
  • Cross-hair overlays
  • Custom picture presets

You’ll be able to cast the ROG symbol on your wall thanks to the top light signal on the monitor.

When it comes to ports, there’s a USB 3.0 hub available along with HDMI 2.0 ports and a DisplayPort 1.4 option.

Ergonomic in design, the ASUS ROG Swift PG27UQ allows for a clear display at almost any viewing angle and can also be mounted to the wall if needed.

The wall mount is 100 x 100 mm, and the absolute dimensions of the monitor are 25” x 3.7” x 15”.

Compared to the Acer version of this monitor, the ASUS version has a better overall build quality and less screen glare.


  • Quick response times
  • Superior contrast
  • Consistent, vivid colors at 144 Hz
  • Designed to reduce eye strain and fatigue


  • Refresh rate dips to 98Hz on 4K HDR

When you’re playing a game in 4K HDR 10-bit, you will notice that the refresh rate drops down to 98 Hz.

You won’t notice much of a difference here, but it is something to note. It’s a problem that all monitors seem to have when displaying at 4K HDR.

Otherwise, you won’t find a monitor that has the level of color availability that designers choose when developing a game, high contrast and ample syncing options.

If you’re a gamer that wants to best possible picture quality, the ASUS ROG Swift PG27UQ is a great choice. For people on a tighter budget you should take a look at the $200 or less monitors we found.
