Overview
G-Sync Pulsar is the reason this monitor exists. It is NVIDIA's backlight-strobing technology that finally works alongside variable refresh rather than instead of it - so you get motion clarity beyond what 360 Hz alone provides, without giving up tear-free frame pacing. Asus builds it into a 27-inch 1440p IPS panel with a 1 ms response, 500 cd/m2 peak brightness and 90% DCI-P3, plus a full ergonomic stand with pivot and +/-45 degree swivel. What Pulsar cannot fix is the panel's contrast: at 1000:1, blacks lift in dark scenes the way every IPS does. There are no speakers, and the HDR listing is bare HDR10 with no certification.

HDR & Brightness Reality
The sheet lists HDR10 and nothing else - no DisplayHDR tier, and a 500 cd/m2 peak against 400 cd/m2 typical, which leaves almost no headroom. Combined with 1000:1 contrast, HDR content here will look flatter than its SDR equivalent. That is not really a criticism of the monitor, because HDR is plainly not what it was designed for: everything about this panel, from Pulsar to the 360 Hz refresh to Esports Dual Mode, points at competitive motion clarity.

Frequently Asked Questions
01 What is G-Sync Pulsar, and why does it matter? +
It is NVIDIA's backlight strobing that runs together with variable refresh. Older strobing modes like ULMB forced you to choose - strobe or VRR, not both. Pulsar does both at once, which sharpens motion beyond what the refresh rate alone gives you.
02 Does Pulsar work with an AMD card? +
No. It is NVIDIA-specific, so on an AMD GPU you lose the single feature that justifies this monitor's price. You would still get 360 Hz and Adaptive-Sync, but a cheaper 360 Hz panel would then make more sense.
03 Is 360 Hz at 1440p actually reachable? +
In esports titles with a strong card, yes - which is precisely the point. 1440p at 360 fps is far more achievable than 4K at 240, and those are the games Pulsar is built for.
04 Does Pulsar make up for the 1000:1 contrast? +
Weak, honestly. 1000:1 is standard IPS and it shows in dark scenes. This panel trades contrast for motion clarity - if you mostly play atmospheric single-player games, a VA or OLED would serve you better.
05 Are the ergonomics good enough for desk work? +
✓ Yes - it pivots, swivels +/-45 degrees and offers 110 mm of height, which is unusually complete ergonomics for an esports monitor.
