The Razer Raptor 27 144Hz is a great 1440p gaming monitor. It has an impressive design with outstanding build quality, a unique and impressive cable management system, and Razer's signature RGB lighting feature in the base. Like most IPS monitors, it has wide viewing angles but a low contrast ratio, so it's not the best choice for gaming in a dark room. It has an outstanding low input lag and a great response time, but there's a bit more motion blur than most 144Hz gaming monitors. It also has great peak brightness and can display a wide color gamut, delivering a decent HDR gaming experience. Unfortunately, it has poor accuracy out of the box.

Our Verdict

7.9 Mixed Usage

The Razer Raptor 27 is a good overall monitor for most uses. It's designed to be a gaming monitor with an incredibly low input lag, excellent motion handling, and support for FreeSync variable refresh rate (VRR) technology. It's good for office use with its high resolution and large size, and you can easily share your screen with others. Unfortunately, the contrast ratio is mediocre and it has poor out-of-box color accuracy, but it displays a wide color gamut for HDR content.

Pros
  • Excellent design and impressive build quality.
  • Low input lag and a great response time.
  • Image remains accurate at an angle.
Cons
  • Poor accuracy out of the box.
7.9 Office

The Razer Raptor 27 is a good office monitor. It has wide viewing angles and great screen real estate. Unfortunately, the stand has a limited range of motion, so it might be difficult to place in an ideal viewing position, and it has only decent reflection handling. It has great peak brightness, though, so glare shouldn't be an issue in most offices.

8.3 Gaming

The Razer Raptor 27 is great for gaming. It has an incredibly low input lag and excellent response time, resulting in clear motion. It has a native refresh rate of 144Hz and supports FreeSync VRR technology, reducing tearing in games. Unfortunately, it has a mediocre contrast ratio, so blacks will appear gray if you game in the dark. However, since it has an IPS panel, it has good viewing angles if you want to use it for co-op gaming.

7.8 Multimedia

The Razer Raptor 27 is a good monitor for multimedia. It has a great amount of screen real estate, outstanding low input lag, and wide viewing angles, great for sharing the latest trends with some friends. It only has decent reflection handling, but it's bright enough that glare shouldn't be an issue in most rooms. Unfortunately, it doesn't look as good in a dark room, due to the low contrast ratio and poor black uniformity.

7.9 Media Creation

Good for media creation. The 27 inch screen on the Razer Raptor 27 offers plenty of space for opening multiple windows at once and the 1440p resolution delivers a clear image. It has good viewing angles if you need to share your screen with others, but unfortunately, the stand only allows for tilt adjustments. It also has great coverage of the Adobe RGB color space used in photo editing.

7.1 HDR Gaming

This is a decent monitor for gaming in HDR. It has a mediocre contrast ratio, so blacks look gray in a dark room, but it has decent peak brightness in HDR and it can display a wide color gamut. The Razer Raptor 27 has great gaming performance, with outstanding low input lag and great response time.

Update 01/20/2021: For consistency, we've changed the swivel adjustment from N/A to 'No'. The score remains unchanged.

Unfortunately, the Razer Raptor 27 has disappointing ergonomics. It has a decent height adjustment range and an outstanding tilt range, but the base can't swivel, and it can't be rotated to portrait orientation.

Update 06/15/2021: At E3 2021, Razer announced a new VESA mount adapter. The adapter is compatible with this model and the new 2021 version.

The back of the monitor has a high-end fabric finish and it feels extremely well-built. There are grooves along the back of the base that provide outstanding cable management. Unfortunately, the stand can't be removed easily.

This monitor is extremely well-built. Most of the frame is made of metal, and the back is covered in a premium texture cloth. The stand wobbles a little bit where it attaches to the back, but this shouldn't cause any issues.

Excellent response time. It's a bit slower than some other 144Hz monitors, like the Gigabyte Aorus AD27QD, but motion still looks clear on the Raptor. The recommended overdrive setting is 'Weak', as it offers the least amount of overshoot. The 'Strong' setting has less motion blur behind fast-moving objects, but there's overshoot in some darker transitions. This monitor's replacement, the Razer Raptor 27 165Hz, has a higher refresh rate and quicker response time.

Update 01/28/2021: We've changed the result of the 10-bit HDR input lag to N/A due to a change in our testing methodology. At 10-bit, we can only achieve 100Hz over HDMI, and 120Hz over DisplayPort. Also, we lack the necessary tools to measure HDR input lag over DisplayPort. The input lag at 100Hz with 10-bit HDR over HDMI is 6.7ms.

Incredibly low input lag, which is excellent for gaming. Console gamers will also appreciate the low input lag at 60Hz, delivering a quick gaming experience.

Differences Between Sizes And Variants

We tested the 27" Razer Raptor 27 144Hz, model number RZ39-0276, which is the first monitor made by Razer. At E3 2021, Razer announced an updated version of this monitor. The new version has a 165Hz refresh rate and is FreeSync Premium certified and THX certified, but otherwise appears to be unchanged.

If someone comes across a different type of panel or if their Raptor 27 doesn't correspond to our review, let us know and we'll update the review. Note that some tests such as the gray uniformity may vary between individual units.

Compared To Other Monitors

The Razer Raptor is a great gaming monitor with an impressive design, but slightly worse motion handling than most similar models. See also our recommendations for the best gaming monitors, the best 27 inch gaming monitors, and the best 1440p 144Hz monitors. Also, check out our recommendations for the best gaming mice and the best gaming keyboards.

Razer Raptor 27 165Hz

The Razer Raptor 27 165Hz replaces the Razer Raptor 27 144Hz. Both monitors are very similar, but the main difference is that the newer one has a higher 165Hz refresh rate, and it has a quicker response time too. The 165Hz model displays a wider color gamut in SDR and HDR, and it has much better out-of-the-box accuracy, but this can vary between units. The newer model has a few extra features, like a THX Cinema mode, but we don't test for that.

LG 27GL850-B

The LG 27GL850-B is slightly better than the Razer Raptor 27 144Hz. The 27GL850-B has a much faster response time, resulting in much clearer motion with almost no noticeable blur behind fast-moving objects. The Razer Raptor has an optional black frame insertion feature, though, which can help improve the appearance of motion. The LG also has a slightly more adjustable stand, and it can be VESA mounted.

ASUS ROG Swift PG279Q

The ASUS ROG Swift PG279Q is slightly better than the Razer Raptor 27 144Hz. The ASUS has much better ergonomics, motion handling, and color accuracy, but the Razer has a significantly better build quality and supports HDR. Also, the ASUS has a slightly higher contrast ratio, better black uniformity, and significantly better reflection handling.

ASUS TUF VG27AQ

The ASUS TUF VG27AQ is better than the Razer Raptor 27 144Hz. The ASUS has a higher native refresh rate, and a faster response time, resulting in clearer motion with less blur behind fast-moving objects. The ASUS also has a more adjustable stand, and it can be VESA mounted. The Razer, on the other hand, has a nicer design, with a unique RGB lighting feature around the base.

Pixio PX7 Prime

The Razer Raptor 27 144Hz and the Pixio PX7 Prime are very similar overall. The PX7 Prime has a slightly faster refresh rate and slightly clearer motion,  but it lacks an optional black frame insertion feature. The PX7 Prime has better ergonomics, so it's easier to place it in an ideal viewing position.

Gigabyte AORUS AD27QD

The Gigabyte AORUS AD27QD is slightly better than the Razer Raptor 27 144Hz, and it's a bit better for gaming. The AORUS has a more adjustable stand, so it's easier to place it in an ideal viewing position. The AORUS also has a faster response time, resulting in slightly clearer motion, with less blur behind fast-moving objects.

ASUS ROG Swift PG279QZ

The ASUS ROG Swift PG279QZ and the Razer Raptor 27 144Hz are very similar for most uses, but the PG279QZ is better for gaming. The ASUS has much better ergonomics, so it's easier to adjust the screen to your ideal viewing position. The ASUS also has a much faster response time, resulting in clearer motion with less blur. The Razer Raptor has an incredible design, and unlike the ASUS it supports HDR, delivering a decent HDR gaming experience.
