Quick verdict
The XG27AQNGV is the Pulsar monitor to buy if you have an NVIDIA graphics card and care most about motion clarity in fast games. TFTCentral's detailed testing found Pulsar working from 76Hz to 360Hz alongside VRR, with no brightness loss (454 nits with Pulsar on) and well-controlled strobe crosstalk thanks to a rolling-scan backlight. They called it a new gold standard for strobing blur reduction. Firmware 1.1.4 fixed early behavior at low frame rates and added a 60Hz ULMB 2 mode.
The limits are those of an IPS LCD: about 1,100:1 contrast, visible IPS glow in dark scenes, and no meaningful HDR. Pulsar also needs an NVIDIA GPU and roughly 90 fps or more; below that it switches off to avoid visible flicker.
27″ · 1440p · 360Hz · IPS (Fast IPS (AU Optronics M270DAN10.6, per TFTCentral)) · G-SYNC Pulsar, ULMB 2
Buy it if
- You play fast shooters on an NVIDIA GPU at 90 fps or more.
- You want very clear motion without OLED burn-in concerns for static desktop work.
- You want a bright, accurate 1440p screen that also works well for the desktop.
Skip it if
- You use an AMD or Intel GPU or a console; Pulsar will not work, and a regular 360Hz monitor costs less.
- You value HDR and deep blacks; choose an OLED such as the PG27AQWP-W.
- Your games often run below 90 fps.

Advantages and drawbacks
Advantages
- Pulsar works with VRR from 76Hz to 360Hz after firmware 1.1.4 (TFTCentral).
- No brightness penalty with Pulsar on: 454 nits measured.
- Rolling-scan backlight keeps strobe crosstalk well controlled across the screen.
- Very low input lag; Pulsar adds only about 2.5 to 3.5 ms.
- Excellent factory calibration, per TFTCentral.
Drawbacks
- Pulsar requires an NVIDIA GPU.
- IPS contrast around 1,100:1 with visible glow in dark scenes.
- No local dimming, so HDR is weak.
- No USB-C or KVM, and an external power brick.

Motion, response, and latency
Pulsar pulses the backlight once per refresh and adjusts the pulse and the overdrive as the refresh rate varies, so strobing and VRR run together. TFTCentral found Pulsar active from 76Hz to 360Hz with VRR, with a default lower cut-off of 90 fps that you can lower to 75 fps; they saw little flicker above 90 fps but noticed it between 75 and 85 fps. Normal overdrive averaged 2.4 ms grey-to-grey at 360Hz without overshoot problems, while the Extreme mode added visible halos.
NVIDIA describes Pulsar as giving over 1,000Hz of effective motion clarity. That compares perceived blur with a hypothetical sample-and-hold display; the panel still refreshes at up to 360Hz, and smoothness still depends on your frame rate. Input lag measured about 1.0 ms at 360Hz, rising by 2.5 to 3.5 ms with Pulsar on.
Image quality and HDR
TFTCentral measured 1,129:1 contrast, excellent factory calibration (average color error of 1.3 in the default mode and 0.8 in sRGB mode), and about 94% of DCI-P3. IPS glow is visible when viewing dark content from an angle. HDR is basic, with no local dimming, so treat this as an SDR monitor with superb motion.
Connectivity, PC, and console notes
One DisplayPort 1.4 with DSC and two HDMI 2.1 ports rated at 40Gbps. There is no USB-C and no KVM. A micro-USB port is used for firmware updates. Consoles can connect over HDMI 2.1, but Pulsar does not work with them.
Firmware: Firmware 1.1.4 fixed Pulsar's interaction with low frame rate compensation so Pulsar switches off correctly below its floor, and added a 60Hz ULMB 2 mode. TFTCentral updated its review for this version. Update through the micro-USB service port.
Warranty and ownership
As an LCD, it has no burn-in risk. Keep the firmware current: the 1.1.4 update materially changed Pulsar behavior at low frame rates. We could not verify ASUS's US warranty length for this model.
Warranty: Unknown (not verified for the US)
Alternatives worth comparing
Acer Predator XB273U F5
27″ · 1440p · 360Hz · IPS
Same class of Pulsar panel with a USB hub and small built-in speakers.
AOC AGON PRO AG276QSG2
27″ · 1440p · 360Hz · IPS
Same panel family; worth buying when it is the cheapest Pulsar option.
ASUS ROG Swift OLED PG27AQWP-W
26.5″ · 1440p · 540Hz · dual mode 720p at 720Hz · WOLED (4th gen, Primary RGB Tandem)
540Hz OLED with deep contrast and bright HDR, but burn-in care and a glossy coating.
Questions buyers ask
Does Pulsar really give 1,000Hz?
No monitor here refreshes at 1,000Hz. NVIDIA's figure describes perceived motion clarity from strobing. The panel refreshes at up to 360Hz.
Will Pulsar work with an AMD card?
No. Pulsar requires an NVIDIA GPU. With AMD or Intel graphics the monitor works as a 360Hz Adaptive-Sync display without Pulsar.
Why does Pulsar turn off at low frame rates?
Strobing at low rates causes visible flicker. The default floor is 90 fps, adjustable to 75 fps; TFTCentral noticed flicker between 75 and 85 fps.
Final recommendation
If you have an NVIDIA GPU and motion clarity is your priority, the XG27AQNGV is the Pulsar monitor to get, with the strongest evidence behind it. If your budget is tighter, the AOC and Acer versions use the same panel class; if you want HDR and contrast, compare it with a fast OLED first.
