ASUS ROG Swift PG27UQ Review: 4K 144Hz G-SYNC Ultimate Gaming Monitor

The ASUS ROG Swift PG27UQ is the perfect gaming monitor thanks to its 4K at 144Hz and full HDR support, 384-zone FALD, and G-SYNC HDR technology.

Bottom Line

The ASUS ROG Swift PG27UQ delivers otherworldly image quality and flawless performance. Moreover, it features a premium design quality and a selection of gaming features. Its MSRP price, however, is not as attractive.


If you’re looking for the absolute best gaming monitor money can buy, you’re going to be blown away by the ASUS ROG Swift PG27UQ.

It supports 4K up to 144Hz and offers NVIDIA G-SYNC as well as a captivating HDR viewing experience with full-array local dimming, stellar brightness, and wide color gamut.

Additionally, it features premium design quality, RGB lighting, and many more nifty gaming features.

Of course, all this is going to cost you, and there are additional things you should be aware of before buying this gaming machine.

Image Quality

The ASUS ROG Swift PG27UQ monitor is based on an IPS panel with 10-bit color depth (8-bit + FRC), 178-degree viewing angles, and a 4ms response time speed.

It’s factory-calibrated to Delta E ≤  3 and covers 97% of the DCI-P3 color space and 99% Adobe RGB making it fit for professional color-critical work.

So, if you’ve been after a monitor that excels at both gaming and professional use, you’ve found your holy grail.

Moving on, the ASUS PG27UQ supports HDR (High Dynamic Range) with a contrast ratio of 50,000:1 and a peak luminance of 1,000-nits for HDR content, which makes the in highlights and shadows become incredibly vivid.

In order to deliver such flawless image quality, the monitor features a full-array local dimming solution with 384 individual zones that help dim the backlight where it’s needed without affecting parts of the screen that need to be bright.

However, in some cases where a lit zone is surrounded by dimmed zones (for instance, moving your cursor across a black background), the light of the lit area will bleed into the dimmed zones creating a halo/bloom effect. So, in some scenarios, it’s preferred to disable local dimming.

Finally, 4K Ultra HD resolution ensures that there are maximum detail and plenty of screen real estate as such high resolution on a 27″ monitor results in a rich pixel density of 163 pixels per inch.


The ASUS ROG Swift PG27UQ claims to support 4K at 144Hz and HDR.

But there’s a catch.

What you won’t find on the product page or written on the box is that the ASUS PG27UQ, due to the DisplayPort 1.4 bandwidth limitations, can only do one of the following three things:

Dropping the color depth to 8-bit isn’t really a big deal. The difference between 8-bit and 10-bit color depth is basically unnoticeable in video games. In fact, most games support only 8-bit color.

Chroma subsampling, on the other hand, makes text appear smudgy and fringy, which becomes an issue for desktop use and video games with a lot of text.

Since 4K UHD resolution is quite demanding as it is, we don’t recommend using chroma subsampling as you’ll hardly get 144FPS at 4K anyway.

Next, the ASUS PG27UQ input lag is only 6ms at 120Hz, which makes for imperceptible delay while the response time speed of 4ms effectively removes trailing artifacts of fast-moving objects.

G-SYNC Ultimate ensures that the gaming performance is buttery smooth even at lower framerates by completely eliminating screen tearing and stuttering with virtually zero input lag penalty (~1ms).


4k 144hz monitor

The ASUS ROG Swift PG27UQ 4K HDR monitor offers an abundance of features!

You will find ASUS’ GameVisual and GamePlus features, which consist of customizable crosshair overlays, on-screen timers, and the FPS, RTS, RPG, Racing, Cinema, sRGB, and Custom picture presets.

In addition, the monitor is flicker-free and has a low blue light filter, so you can game for hours on end without straining your eyes.

Another feature of the ASUS ROG PG27UQ is that it can emit the ‘Republic Of Gamers’ logo as well as customizable lighting onto your desk and/or wall.

ASUS Aura Sync RGB allows you to synchronize the monitor’s RGB lighting with other Aura Sync compatible peripherals and use various glowing patterns and color combinations.

There’s also a light sensor that can automatically adjust screen brightness according to the ambient lighting.

Fans of backlight strobing will be disappointed to find out that the ASUS PG27UQ does not feature NVIDIA ULMB (Ultra Low Motion Blur) or any other form of Motion Blur Reduction. Luckily, there isn’t any prominent ghosting or motion blur in fast-paced games as the pixel response time speed of the monitor is excellent.

Design & Connectivity

The appearance of the monitor may seem too flashy to some, even when the RGB LEDs and projectors are turned off, but the design itself is very sturdy with versatile ergonomics including -/+ 35° swivel, 90° pivot, up to 120mm height adjustment, -5°/20° tilt, and 100 x 100mm VESA mount compatibility.

The matte black bezels are a bit thicker due to the FALD implementation, but they look rather nice regardless. For navigation through the OSD (On-Screen Display) menu, there’s a joystick as well as three buttons for shortcuts at the back of the monitor.

Lastly, the screen has an anti-glare matte coating, which eliminates reflections, and there’s a relatively silent integrated fan that keeps the display cool.

Connectivity includes HDMI 2.0, DisplayPort 1.4, a headphones jack, and a dual-USB 3.0 hub. Both display connectors support HDCP 2.2, so you can watch protected content from Netflix, Amazon Video, etc. in 4K Ultra HD.

Price & Similar Monitors

The ASUS ROG Swift PG27UQ price was initially $2,000, but nowadays, it can be found for as low as $1,300.

Acer has their own model based on the same panel as the PG27UQ called the Acer Predator X27 which goes for around the same price.

Its design, however, lacks pivot adjustment and has less customizable RGB lighting, though it does have built-in speakers and two extra USB 3.0 ports.

We recommend going for whichever is available/cheaper, or according to your preference of the design, RGB lighting technology used, etc.

If you’re looking for something similar but cheaper, check out the LG 27GN950 4K 144Hz gaming monitor with a faster 1ms GtG IPS panel and 98% DCI-P3 color gamut.

It doesn’t have a G-SYNC module, but it supports FreeSync and it’s certified as G-SYNC Compatible, so VRR performance will be buttery-smooth.

Additionally, it supports DSC (Display Stream Compression) allowing you to use 144Hz at 4K with 10-bit color depth without any visual artifacts.

However, it doesn’t offer as good HDR image quality, but merely a glimpse of what HDR can truly do, with DisplayHDR 600 certification.

On balance, the ASUS PG27UQ, along with the Acer X27, is surely one of the best gaming monitors ever made, but just like all ground-breaking technology, it will cost you.
