The HP OMEN 27qs is a 27-inch, 1440p gaming monitor. Part of HP's OMEN gaming lineup, it's one of the few with a 240Hz refresh rate, and it sits alongside the HP OMEN 27c, which uses a different panel. It's meant to be a cheaper alternative to popular 1440p, 240Hz gaming monitors, like the Dell Alienware AW2723DF and Gigabyte M27Q X. Because of this, it has features you'd expect to find in a gaming monitor, like FreeSync variable refresh rate (VRR) support and G-SYNC compatibility to reduce screen tearing with any type of graphics card. While it has one DisplayPort 1.4 input, it's limited to HDMI 2.0 bandwidth on its two HDMI ports, so it isn't designed to take full advantage of current-gen gaming consoles or high-end graphics cards.

Our Verdict

7.8 Mixed Usage

The HP OMEN 27qs is good for most uses. It performs best as a gaming monitor because of its fast 240Hz refresh rate, VRR support, and quick response time for smooth motion handling. It's also good for office use and media creation in bright rooms thanks to its good reflection handling and high peak brightness. Despite having a good pixel density, the text clarity is only decent as there's some color fringing. It's decent for media consumption thanks to its good accuracy and wide viewing angles that make it easy to share the screen with someone else, but the picture quality in dark scenes is disappointing due to its low contrast. It also has a local dimming feature that's automatically enabled in HDR but results in a ton of blooming.

Pros
  • Great peak brightness.
  • Wide viewing angles.
  • High 240Hz refresh rate.
  • FreeSync VRR and G-SYNC compatibility.
  • Fast response time.
Cons
  • No swivel adjustments.
  • Some color fringing around text.
  • No HDMI 2.1 bandwidth.
  • Terrible local dimming feature.
7.8 Office

The HP 27qs is good for the office. It gets bright enough to fight glare if you want to use it in a well-lit office space and has good reflection handling. It has wide viewing angles that make it easy to share your screen with someone else, and while it has good ergonomics, it doesn't offer any swivel adjustments. It has a big enough 27-inch screen to open two windows side-by-side, but sadly, its text clarity is just decent as there are some color fringing issues.

Pros
  • 27-inch screen.
  • Great peak brightness.
  • Good reflection handling.
  • Wide viewing angles.
Cons
  • No swivel adjustments.
  • Some color fringing around text.
8.3 Gaming

The HP OMEN 27qs is great for gaming. It has a fast 240Hz refresh rate and FreeSync VRR and G-SYNC compatibility to reduce screen tearing. Motion looks smooth thanks to its fast response time across its entire refresh rate range, and it has low input lag for a responsive feel. Unfortunately, it doesn't have HDMI 2.1 bandwidth to take full advantage of high-end graphics cards and gaming consoles. Lastly, it looks disappointing in dark rooms due to its low contrast ratio, making blacks look gray in dark scenes.

Pros
  • High 240Hz refresh rate.
  • FreeSync VRR and G-SYNC compatibility.
  • Fast response time.
  • Low input lag.
Cons
  • No HDMI 2.1 bandwidth.
  • Low contrast ratio.
7.4 Media Consumption

The HP OMEN 27qs is decent for media consumption. Images look life-like thanks to its wide color gamut and excellent accuracy before calibration, and it has a 1440p resolution to deliver good enough details with most content. Its wide viewing angles are useful if you want to watch content with a friend next to you as the image remains consistent from the sides, but it doesn't offer swivel adjustments. It's good for watching content in bright rooms thanks to its high peak brightness and good reflection handling, but it struggles in dark rooms as it has a low contrast ratio, and its local dimming feature performs terribly. Unfortunately, the local dimming is always on in HDR, which is distracting.

Pros
  • Great peak brightness.
  • Good reflection handling.
  • Wide viewing angles.
Cons
  • No swivel adjustments.
  • Low contrast ratio.
  • Terrible local dimming feature.
7.9 Media Creation

The HP OMEN 27qs is good for media creation. It has excellent accuracy before calibration, so you won't need to get it calibrated unless you need perfectly accurate colors. It also has wide viewing angles that make it easy to share your screen with a coworker or client, but without swivel adjustment, you can't easily turn the screen. Its 27-inch screen is big enough to multitask, but the text clarity is just decent, as there are color fringing issues with some text.

Pros
  • Great peak brightness.
  • Good reflection handling.
  • Wide viewing angles.
  • Excellent accuracy before calibration.
Cons
  • No swivel adjustments.
  • Some color fringing around text.
6.7 HDR

The HP OMEN 27qs is mediocre for HDR. While it displays a wide range of colors and has good HDR peak brightness, the picture quality is severely worsened because of its edge-lit local dimming feature, which is always on in HDR. It has a ton of blooming in dark scenes and fails to improve the contrast. Also, small highlights don't pop against the rest of the image, which is disappointing for HDR.

Pros
  • Displays wide range of colors.
Cons
  • Low contrast ratio.
  • Terrible local dimming feature.
  • Small highlights don't stand out against rest of image.
  • 7.8 Mixed Usage
  • 7.8 Office

Differences Between Sizes And Variants

We tested the 27-inch HP OMEN 27qs, which is the only size available for this monitor. This means the review is only valid for this monitor, but there are other 240Hz monitors from HP OMEN's lineup, and you can see the differences between some of them below.

Model Size Panel Type Resolution Max Refresh Rate Curve
27qs 27" IPS 1440p 240Hz No
27c 27" VA 1440p 240Hz Yes
27s 27" IPS 1080p 240Hz No

Our unit was manufactured in March 2023. The Rev. number is B0BT1111; you can see the label here. We tested this monitor with firmware 1.70.5.0.

Compared To Other Monitors

The HP OMEN 27qs is a great gaming monitor with a 240Hz refresh rate, FreeSync VRR and G-SYNC compatibility, and smooth motion handling. It offers great value if you want a low-cost 1440p, 240Hz gaming monitor, so it's a cheaper alternative to more expensive options like the Dell Alienware AW2723DF and the Gigabyte M27Q X. However, there are some trade-offs for that, as it doesn't support compression, so you can only reach the max refresh rate with 8-bit signals and not 10-bit, and it can't downscale 4k signals from gaming consoles either, which those more expensive options can do. If you want a high refresh rate monitor strictly for PC gaming that won't break the bank, you'll be happy with this one.

See our recommendations for the best 240Hz monitors, the best budget and cheap gaming monitors, and the best 1440p gaming monitors.

Dell Alienware AW2723DF

The Dell Alienware AW2723DF and the HP OMEN 27qs are both great 1440p, 240Hz gaming monitors with many similarities, but there are a few differences. One main difference is that the Dell has an overclock feature to 280Hz, which the HP doesn't have. Also, the Dell is a bit more versatile for console gaming as it downscales 4k signals, which the HP can't do. However, the HP has a slightly faster response time at high refresh rates, which is great for competitive gaming. The HP is also the better choice if you need something for a bright room, as it gets a bit brighter and has much better reflection handling.

Gigabyte M27Q X

The Gigabyte M27Q X and the HP OMEN 27qs are both 1440p, 240Hz gaming monitors, but there are a few differences between them. The Gigabyte is a bit more versatile for console gaming as it downscales 4k signals, which the HP can't do, and it has a more versatile backlight strobing feature that works at the same time as VRR. The Gigabyte has some extra features that the HP doesn't have, like a KVM switch and a USB-C port. On the other hand, the HP has a more ergonomic stand, as you can rotate it into portrait mode, which you can't do with the Gigabyte.

Samsung Odyssey G7 C32G75T

The Samsung Odyssey G7 C32G75T and the HP OMEN 27qs are different types of 1440p, 240Hz gaming monitors. They even have different panel types as the Samsung has a much higher contrast ratio, and it performs better in dark rooms, while the HP has wider viewing angles, making it better for co-op gaming. The Samsung is more versatile for console gaming as it downscales 4k signals, which the HP can't do. While each has a fast response time, the HP has a bit less smearing with fast-moving objects. The HP is also more reliable as it has fewer bugs than the Samsung with its VRR support.

HP OMEN 27i

The HP OMEN 27qs is a newer and higher-end monitor than the HP OMEN 27i, so there are a few differences. The 27qs has a higher 240Hz refresh rate and much better motion handling for a smoother feel. The 27qs also has better picture quality with higher peak brightness and improved color accuracy, and it even supports HDR, which the 27i doesn't, but it has limited HDR performance anyway.

The build quality is great. It features a matte plastic body that feels good, and there aren't any obvious issues. It's stable on the stand as it doesn't wobble much, which is great. However, like some other monitors, the pixels close to the bezels disappear when viewing the screen from the sides, but this isn't something you'll notice when sitting directly in front.

The ergonomics are good. It's easy to adjust the screen when you're sitting directly in front of it, but without swivel adjustment, it's hard to turn the screen to show it to someone next to you. Luckily, the height adjustment is good, and at its lowest setting, the bottom of the screen is 2.6" (6.5 cm) from the desk. The stand also features a clip for cable management.

Contrast With Local Dimming

The HP OMEN 27qs has a low native contrast ratio that makes blacks look gray in the dark. While it has a local dimming feature, it only turns on in HDR, and it makes the entire image brighter, which is why the contrast ratio is worse with local dimming on.

Edge

This monitor has an edge-lit local dimming feature with eight zones, and it performs terribly. It only comes on in HDR, and you can't disable it, meaning it's always on when watching HDR content. Any bright object causes an entire zone to light up, resulting in distracting blooming, which is noticeable even with subtitles. That said, most content causes all the zones to turn on, so the issues with blooming are only noticeable in dark content. Unfortunately, the algorithm is slow to react to objects moving across the screen, which is also distracting. All in all, it's a bad implementation of local dimming that fails to improve the contrast, and because it's always on in HDR, it severely hinders its HDR performance.

The HP OMEN 27qs has good HDR brightness. While it gets bright with most content, small highlights don't pop against the rest of the image due to its low contrast and terrible local dimming feature. Also, the PQ EOTF doesn't follow the target curve well, as most dark scenes are too dark. Unfortunately, there aren't any settings in HDR besides Sharpness, and the local dimming is always on.

The black uniformity is poor. In SDR, the entire screen is blue, and there's noticeable clouding and backlight bleed throughout. In HDR, where the local dimming feature is automatically enabled, and you can't turn it off, the uniformity is even worse because there's more blooming around bright objects.

The HP OMEN 27qs has excellent accuracy before calibration. While it doesn't have a dedicated sRGB mode, many of the Color Modes include an sRGB clamp. It locks colors well to the sRGB color space, and the white balance and gamma are both good but imperfect. That said, the color temperature is on the cold side, giving the image a blue tint. Only the 'Gaming' and 'Native' modes don't use the sRGB clamp, and the main advantage to using those is that they get brighter. The 'Gaming' mode is the more accurate of the two, but colors are oversaturated, as you can see here. The modes that include the sRGB clamp are:

The text clarity is decent, but it isn't as good as other 27-inch, 1440p displays because there's color fringing when using Windows ClearType (top photo). If you find this distracting, it's better to disable it. These photos are in Windows 10, and while the fringing isn't as aggressive with Windows 11, it's still there as you can see with ClearType on and with ClearType off.

The response time at the max refresh rate of 240Hz is fantastic. Motion looks smooth, and there's minimal blur or inverse ghosting with fast-moving objects. The recommended Response Time setting of 'Level 3' has a faster response time than 'Level 1' and 'Level 2' and has less overshoot than 'Level 4'. That said, motion looks fantastic with any of the settings up to and including 'Level 4', so you can choose whatever looks best for you.

The response time at 120Hz is excellent. Unlike at the max refresh rate, the recommended overdrive setting is 'Level 2' because there's more overshoot at the higher Response Time settings. Because of that, you may need to change the setting if the frame rate of your game drops or if you change games, but 'Level 2' is also a good set-and-forget mode as it performs consistently well across the entire refresh rate range.

The response time at 60Hz is great. It performs similarly to higher refresh rates, but there's more blur as some transitions are slow. The recommended overdrive setting is also 'Level 2' as higher settings have too much overshoot. Additionally, the monitor's LFC feature kicks in at 60Hz, doubling the refresh rate to 120Hz when you have VRR enabled, so you only get a true 60Hz refresh rate with VRR disabled.

The HP OMEN 27qs has an optional backlight strobing feature, commonly known as black frame insertion. You need to turn off Adaptive Sync to use the MPRT setting, which has five different options, with '5' being the most aggressive, but it also results in the lowest brightness. The feature does a decent job at reducing persistence blur but also has image duplication.

The HP OMEN 27qs monitor can't take full advantage of the PS5 as it's limited to HDMI 2.0 bandwidth and doesn't support 4k signals. That said, there aren't any compatibility issues with the signals it supports.

The HP OMEN 27qs has limited compatibility with the Xbox Series X|S. It doesn't support HDMI 2.1 bandwidth to fully utilize the console. HDR doesn't work either, as the console only supports HDR with 4k signals, which the monitor doesn't accept.

macOS Compatibility

This monitor works well with macOS when using a DisplayPort to USB-C cable. You can reach its max refresh rate, and both VRR and HDR work without issues. If you're using a MacBook, windows return to the original position when waking up the laptop from sleep, but not when you close the lid.

The HP OMEN 27qs has a few extra features, including RGB lighting on the back that you can control with different presets in the External Lighting page of the on-screen display. There are other settings, including:

  • Audio Mode: There are different audio settings available, letting you customize the sound how you like.
  • Crosshair: You can choose different virtual crosshairs available, giving you a competitive advantage as your game's anti-cheat tool won't detect it.
  • Diagnostic Patterns: Displays full-screen images of different colors so you can see any uniformity issues or dead pixels more easily.
  • Frame Rate: Displays the current frame rate from your source.
  • Image Scaling: Lets you change the aspect ratio of the display.
  • Multi-Monitor Align: Makes it easier to align the monitor next to another by displaying an overlay.
