The Asus ROG Swift PG27UQ G-SYNC HDR Monitor Review: Gaming With All The Bells and Whistles

Delayed past its original late 2017 timeframe, let alone the April and May estimates, NVIDIA’s G-Sync HDR technology finally arrived over the last couple months courtesy of Asus’ ROG Swift PG27UQ and Acer’s Predator X27. First shown at Computex 2017 as prototypes, the 27-inch displays bring what are arguably the most desired and visible aspects of modern gaming monitors: ultra high resolution (4K), high refresh rates (144Hz), and variable refresh rate technology (G-Sync), all in a reasonably-sized quality panel (27-inch IPS-type). In addition to that, of course, are the various HDR-related capabilities with brightness and color gamut.

Individually, these features are just some of the many modern display technologies, but where resolution and refresh rate (and also input latency) are core to PC gaming, those elements typically work as tradeoffs, with 1440p/144Hz being a notable middle ground. So by the basic 4K/144Hz standard, we have not yet had a true ultra-premium gaming monitor. But today, we look at one such beast with the Asus ROG Swift PG27UQ.

As an ultra-premium gaming monitor of that caliber, the PG27UQ also has an ultra-premium price of $1999. For reasons we’ll soon discuss, the pricing very much represents the panel’s HDR backlighting unit, quantum dot film, and G-Sync HDR module. The full-array local dimming (FALD) backlighting system delivers the brightness and contrast needed for HDR, while the quantum dot film enhances the representable colors to a wider gamut, another HDR element. The new generation G-Sync HDR module deals with the variable refresh implementation, but with HDR, high refresh rate, and high resolution combined, bandwidth constraints require chroma subsampling beyond 98Hz.
