I had to go back in time a bit to find five QHD 240 Hz monitors to compare the Omen 27qs’s performance. This category is dominated by 165 Hz screens. However, for hardcore gamers, life begins at 240 Hz. We have BenQ’s EX270QM, RCA’s M27PG135F, AOC’s AG274QG and CQ27G3Z and Gigabyte’s M27QX.

Usually, I would say that the Omen 27qs’s 5ms response is a disadvantage to the others’ 4ms. But since its overdrive is so good, there is no visual difference. HP has tuned it perfectly to remove blur without creating trail artifacts. You can use it up to level four. When total lag is considered, the Omen 27qs rockets to the top with a score that would embarrass a 360 or 500 Hz display. This is the part where I remind you about the 98% rule of performance.
Test Takeaway: The Omen 27qs delivers speed nearly equal to a 360 or 500 Hz monitor when total lag is considered. While the higher refresh screen is a tad smoother, the HP’s low input lag cannot be ignored. You also can’t ignore its low price. A 500 Hz screen will cost at least twice as much money for a tiny bit more speed and lower resolution. Performance bargains don’t get better than this.
Viewing Angles

The Omen 27qs is one of the best IPS panels I’ve photographed. There is almost no change to the sides, either in color or brightness. The top view goes green and darkens by around 40%, which is typical of the technology. Though not many users will share a 27-inch panel, this one can be viewed by two people comfortably.
Screen Uniformity

My Omen 27qs sample’s screen uniformity was exemplary at a 7.05% deviation from the center zone in the black field test. There were no visible issues when viewed in total darkness. Color was evenly toned from edge to edge. This is a very high-quality panel.
