Viewing Angles

The Omen 27i delivers viewing angles comparable to any IPS monitor. To the sides, there is a slight blue shift along with a 30% reduction in brightness. From the top, the image gets a bit red and light drops by around 50%. In either case, detail remains visible in all areas of the image.

Quality control is certainly evident in our Omen 27i sample. With only a 5.91% deviation, screen uniformity is visually perfect. HP has avoided any bleed or glow that sometimes crops up with IPS panels. This monitor won’t show any hotspots or artifacts at any brightness level. Color aberrations were nonexistent. 

Pixel Response & Input Lag

As you can see, high refresh rates are not created equal. Though the differences are small, more Hertz isn’t a guarantee of success. The Omen 27i makes the most of its 165Hz and manages to pip the 200Hz GM27-CF in the lag test while matching its panel response score. HP’s overdrive is one of the best we’ve seen, and it almost completely eliminates motion blur with no ghosting artifacts. A 21ms lag score will only be beaten by a handful of 240Hz monitors.
