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

Test Results
The stand is large and supports the monitor extremely well but there's still a bit of wobble to it. The base is thin enough that you can still place small objects in front of it, and there's a unique RGB feature around the base.
Update 03/25/2021: We set the tilt to 'No' by mistake. It can tilt from 2.5 degrees to -90 degrees. It has been fixed.
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.
The borders are incredibly thin on three sides, great for a multi-monitor setup.
The monitor itself is fairly thin, but it'll take up more space on your desk with its large stand.
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.
As is the case with most IPS panel monitors, the contrast ratio is mediocre. Blacks will look gray when viewed in dark rooms.
The Razer Raptor 27 doesn't support local dimming. The above video is for reference only.
Great SDR peak brightness. This monitor should be able to overcome glare in any room.
Decent peak brightness in HDR. Small highlights in some scenes stand out a bit, but it isn't quite bright enough. It can get a bit brighter than the Gigabyte Aorus AD27QD.
Good horizontal viewing angles, which is typical of an IPS panel, although it doesn't perform as well as some other monitors.
Good vertical viewing angles. The edges of the screen may appear a bit darker if you sit close to it, but this shouldn't be a problem for most people.
Excellent gray uniformity. The sides of the screen are a bit darker than the rest, but this shouldn't be very noticeable with most content.
Poor black uniformity. There's visible clouding throughout and there's blooming around the center cross. This is most noticeable when viewed in the dark.
The Razer Raptor 27 has poor out-of-box color accuracy. Most colors are inaccurate and the color temperature is much warmer than the target, so each color is closer to red. Fortunately, the gamma follows the curve well, although dark scenes may appear darker than they should.
After calibration, the Razer Raptor 27 has excellent accuracy. Any remaining inaccuracies aren't noticeable.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit even for the same model, due to manufacturing tolerances.
Excellent SDR color gamut, with near-perfect coverage of the sRGB color space used in most content. It also has excellent coverage of the wider Adobe RGB color space used for some professional photo editing.
Outstanding SDR color volume. It's mainly limited by the low contrast ratio, as it can't produce dark saturated colors very well.
The Razer Raptor 27 displays a wide color gamut, with great coverage of the DCI P3 color space used in most current HDR content.
Mediocre HDR color volume. Unfortunately, colors aren't as bright in HDR, and it can't display dark, saturated colors very well.
There are no signs of temporary image retention, even immediately after displaying our high-contrast static test image for ten minutes, which is great.
The Razer Raptor 27 has outstanding gradient performance, with no noticeable banding in any shade.
Unfortunately, there are some signs of color bleed. This shouldn't be an issue with most content, though.
This monitor has decent reflection handling, similar to the Acer Predator X27 and the Gigabyte Aorus AD27QD.

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.
The Razer Raptor 27 has a flicker-free backlight at all brightness settings. There's an optional Black Frame Insertion (BFI) feature that can improve the appearance of motion. Like most FreeSync monitors, this feature isn't available if FreeSync is enabled. The setting that controls this feature is called Motion Blur Reduction.
This monitor has an excellent fast refresh rate. It supports AMD's FreeSync VRR technology and it has an excellent wide VRR range over both HDMI and DisplayPort.
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.
The 1440p, 27 inch screen is great for gaming or multitasking.
Update 03/25/2021: We've changed the USB-C result to indicate power delivery and DisplayPort Alt Mode.
Update 01/28/2021: We incorrectly indicated the DisplayPort version as 1.4 instead of 1.2. It has been fixed.
The single USB-C port supports DisplayPort Alt Mode and USB-C power delivery, but it's also the upstream port.
The Razer Raptor 27 has a few additional features. It can overlay a refresh rate counter, and it has a unique RGB feature around the base. The RGB feature can only be controlled through Razer's Synapse software, and the USB upstream cable must be connected to your computer.
A single joystick nub is used to navigate the on-screen display, similar to the one found on LG's UltraGear monitors, like the LG 27GL850-B/27GL83A-B.
