Tom's Hardware has reviewed the Asus ROG Strix XG27AQGNV, a 27-inch QHD IPS gaming monitor featuring Nvidia's G-Sync Pulsar technology. The review notes that G-Sync Pulsar, which syncs the backlight with the frame rate, provides smooth motion clarity without the brightness penalty typical of strobing, making this display a strong alternative to OLED for gamers prioritizing motion resolution.

The Asus ROG Strix XG27AQGNV is a 27-inch monitor with a 2560x1440 resolution and a 360 Hz refresh rate. It supports G-Sync Pulsar, which the reviewer describes as the only way an LCD can achieve perfect motion resolution, keeping moving objects as clear as stationary ones. The monitor also includes a traditional overdrive with a 400-step precision slider and three presets, though overdrive can only be used when Pulsar is turned off.

The display features a precise gamma control with adjustments in 0.01 increments, a fine-tuned color temperature with RGB sliders, and a brightness adjuster graduated in nits. It offers six picture modes, including sRGB and G-Sync Esports, and a suite of GamePlus options such as aiming points and frame counters. The build quality includes a stable metal base, stiff ergonomics, and a backlit ROG logo with Aura Sync.

Priced at $500, the XG27AQGNV is one of only four monitors with G-Sync Pulsar. The reviewer notes that while it does not achieve full DCI-P3 coverage, it covers about 120 percent of sRGB. The monitor ships with DisplayPort and USB cables, and its inputs include DisplayPort 1.4 with DSC, two HDMI 2.1 ports, and a USB hub.

Analysis

Why This Matters

G-Sync Pulsar offers a significant improvement in motion clarity for LCDs without dimming the image, potentially changing the gaming monitor landscape.
This monitor provides a viable alternative to OLED for users who prefer LCD but want near-perfect motion resolution at a competitive price.
The inclusion of highly precise gamma and color controls sets a new standard for on-screen calibration in gaming monitors.

Background

G-Sync Pulsar is a technology that synchronizes the LED backlight array with the monitor's refresh rate, effectively strobing without the brightness loss of traditional black-frame insertion. It was first reviewed by Tom's Hardware on the Acer XB273U F5 earlier this year. The Asus ROG Strix XG27AQGNV is part of Asus's more affordable Strix line, retaining core gaming features while omitting some premium extras found in the ROG Swift series.

Key Perspectives

Tom's Hardware reviewer: Praises the motion clarity and response time, calling the G-Sync Pulsar feature transformative for LCD monitors. Highlights the precise gamma slider and the absence of a brightness penalty as major advantages. Prospective buyers: The $500 price is premium for a 27-inch QHD monitor, but those seeking smooth motion without moving to OLED may find it worthwhile. The monitor's sRGB+ coverage and precise controls appeal to users who value color accuracy and calibration. Skeptics: May point out that the monitor does not fully cover DCI-P3 color space, that the 2.2 gamma preset is lighter than standard, and that overdrive is only functional when Pulsar is off. Additionally, OLED monitors generally offer superior contrast and faster pixel response, though often at a higher price.

What to Watch

How G-Sync Pulsar adapts to future graphics cards and whether it becomes standard in more monitors.
Pricing and availability of other G-Sync Pulsar models, as only four exist at launch.
User feedback on the reliability and real-world performance of the backlight strobing technology in long gaming sessions.
