Product Snapshot
Overview
Announced in mid-2023, the HP OMEN 27QS is a mid-market gaming monitor with a maximum 240Hz refresh rate for fast-paced gaming. The monitor’s 27-inch screen provides sufficient screen real estate and a wide viewing angle, synonymous with top-tier computer monitors. The 27QS also has a rapid 4.2 ms response time, which places it among the best gaming monitors on the market.
With both FreeSync VRR and G-Sync compatibility, the 27QS works great with any type of graphics card, but its lack of a HDMI 2.1 port may limit connectivity to next-gen gaming consoles. Still, color handling is impressive courtesy of a wide HDR and SDR color gamut, and since it is flicker-free, there are very low chances of eye strain.

Consensus
our Verdict
The 27-inch HP OMEN 27QS is a mid-tier gaming monitor that boasts a 389.5 nit brightness rating, making it easily visible even in a well-lit environment. The display also has high color accuracy, resulting in bright and vivid colors courtesy of a 94.35% coverage of the DCI P3 color gamut, placing it in the top 10% of tested monitors in this regard. While its low 998:1 contrast ratio may result in dark scenes appearing gray, the display does have a local dimming feature, which works when viewing HDR content.
Professional gamers will appreciate the snappy reaction to commands on the 27QS, making it perfect for fast-action gaming. The display has a low 8.5ms input lag, and this, coupled with its 1ms response time for tear-free gaming, makes it ideal for the avid player looking for the highest return on their money for a gaming display.
