Tom's Hardware reviewed the Asus ROG Strix XG27AQGNV, a 27-inch QHD IPS gaming monitor with a 360Hz refresh rate and Nvidia's G-Sync Pulsar feature. G-Sync Pulsar synchronizes the backlight's LED array with the frame rate, a form of strobing that avoids the brightness penalty usually associated with black-frame insertion. The reviewer says it is the only way an LCD can achieve perfect motion resolution, making moving objects as clear as stationary ones.
In testing, the monitor delivered OLED-level smoothness and responsiveness, according to the review. It also offers unusually precise calibration options: gamma can be adjusted in 0.01 increments, overdrive has a 400-step user control, and brightness is set in nits. Color accuracy and build quality are praised, and the monitor includes a full set of GamePlus features and six picture modes.
The main drawbacks are a smaller color gamut than other fast monitors — the reviewer calls it 'sRGB+' rather than full DCI-P3 — and no dynamic dimming, so HDR contrast is no better than SDR. At $500, the XG27AQGNV is priced above most 27-inch QHD displays, but the review notes it is one of only four monitors with G-Sync Pulsar and the only LCD alternative for buyers who want OLED-like motion without buying an OLED.
