Asus ROG Strix XG27AQGNV review: OLED-like motion on LCD bargain

G-Sync Pulsar removes blur by flashing the backlight in sync with each new frame instead of leaving it on all the time. To see why that helps, you need to know where the blur comes from.

Variable refresh rate, the tech behind G-Sync and FreeSync, matches the monitor’s refresh to your graphics card so you get no tearing or stutter. It doesn’t fix blur. An LCD holds each frame on screen until the next one arrives, and your eye smears that held image as things move. You’d need at least 500Hz to call LCD motion truly sharp. For comparison, an OLED pixel or LED can flash 20,000 times a second, while a fast LCD layer manages about 500.

Older fixes have trade-offs. Overdrive pushes pixels to change faster but can cause halos. Black frame insertion, which strobes the backlight, cuts brightness. Pulsar is a form of strobing that avoids the brightness penalty. Nvidia’s updated version, shown at CES 2026, pulses narrow horizontal bands of the backlight as the screen draws each frame, so each part lights up only once its pixels have settled. Nvidia claims that can make a 360Hz panel look closer to a 1,000Hz one, with up to four times the motion clarity of a regular VRR display.

The basics are simple: a 27-inch IPS panel (Asus calls it Ultra-Fast IPS), 2560×1440 resolution and a top refresh rate of 360 Hz. You’ll also see the model written as XG27AQNGV in some places.

• G-Sync Pulsar with low frame rate compensation, which stops flicker when your frame rate drops.
• Standard overdrive with three presets, plus a fine 400-step slider for anyone who turns Pulsar off.
• A wide color mode covering around 120% of sRGB, though not the full DCI-P3 range used for film.
• Six picture modes, including sRGB and a G-Sync Esports mode.
• GamePlus extras such as aiming points, a frame counter, a timer and a stopwatch.
• An ambient light sensor on top that can adjust brightness and color automatically.

Being a ROG Strix rather than a pricier ROG Swift, it gives up a few minor extras, but nothing that affects gaming. On the back you’ll find a DisplayPort input with Display Stream Compression, a pair of HDMI ports, a headphone jack and spare USB ports, though the recessed inputs make chunky plugs fiddly.

This is where the monitor earns its price. The reviewer found playing on it instantly addictive, with smoothness and response that matched any premium display. With Pulsar on, there was no motion blur and input lag was very low. The verdict was that a Pulsar screen beats even a 500Hz LCD for motion.

Overdrive is greyed out while Pulsar runs, and when tested on its own it reduced blur without getting rid of it. That tells you Pulsar, not raw speed, is doing the heavy lifting.

For desk work, the 27-inch, 1440p screen is sharp and colorful enough for browsing and photo editing. If you’re used to a Quantum Dot monitor with a huge color range, you’ll notice a little less color, but the gap isn’t big.

HDR is the weak spot. The monitor has no dynamic dimming (the ability to darken parts of the backlight), so HDR content gets no more contrast or depth than SDR. In HDR games it looked slightly more colorful, thanks to some deliberate oversaturation by Asus, but not more dramatic. Contrast settings also didn’t carry over from SDR, so they had to be changed each time.

Out of the box, gamma was too light. The fix is one of this monitor’s best features: a gamma slider that moves in 0.01 steps, instead of the usual five or six presets spaced 0.2 apart. With that and the precise RGB color temperature sliders, the tester got near-perfect accuracy. Brightness is even adjusted in nits.

Buy it if you play competitive shooters or other fast games, have a graphics card that can push high frame rates at 1440p, and want OLED-like motion on a bright LCD. It also suits tinkerers who like to calibrate their screen.

Skip it if HDR movies and deep blacks matter most. An OLED still wins on contrast and vivid color, and the reviewer said they would personally pick an OLED. It’s also worth knowing Pulsar’s gains shrink outside high frame rate gaming.

Choice is growing. When this model was reviewed, it was one of only four monitors offering G-Sync Pulsar, and Asus, Acer, AOC and MSI were all bringing out 27-inch, 1440p, 360Hz Pulsar displays. Newer scaler chips build G-Sync into the monitor itself, removing Nvidia’s separate module and helping bring prices down over time.
