Delayed past its original late 2017 timeframe, let alone the other shipping dates, 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.
