Test Results
The Lenovo Legion Y27q-20 has a simple design that isn't too flashy and shouldn't stick out in an office environment. It has thin borders on three sides and a thicker bottom bezel. The V-shaped stand takes a fair amount of space but supports the monitor well.
The V-shaped stand is heavy, as both the feet and column are metal. It feels sturdy and only wobbles slightly.
Good ergonomics. It allows for all manner of adjustments, although the swivel range is a bit narrow.
The back is plain except for the airflow vents and branding. There's a small loop at the bottom of the stand to pass cables through for cable management. There's a quick-release feature to remove the stand if you want to VESA-mount it.
The borders are thin and aren't distracting, great for multi-monitor setups.
The monitor is relatively thin, but the stand requires a fair amount of desk space.
The Lenovo Legion Y27q-20's build quality is good. The stand is mostly metal except for the joints and hinges, which are plastic. It supports the monitor well and only wobbles slightly. The hinges are well-made and allow for precise ergonomic adjustments. The back panel is made out of plastic with a fine grainy texture, and it seems to be the weakest part of the monitor as it flexes quite a bit. That said, there aren't any apparent gaps or loose parts, and you shouldn't have any issues with it.
The Lenovo Legion Y27q-20 has a sub-par contrast ratio, resulting in blacks that appear closer to gray when viewed in the dark. It's slightly lower than the advertised 1000:1 contrast; however, this can vary between units.
The Lenovo Y27q-20 doesn't have a local dimming feature. The video above is provided for reference only.
The Lenovo Legion Y27q-20 has good SDR peak brightness. It's very consistent across different content and close to the advertised 350 cd/m². It's bright enough to overcome glare in most lighting conditions, but it might struggle a bit if there's direct sunlight.
We measured the SDR peak brightness after calibration with Game Mode (picture mode) set to 'Off', and Color Temperature set to 'User'.
The HDR peak brightness is mediocre. It's advertised as having VESA HDR400 certification, but it falls short of the required 400 cd/m². Just like in SDR, it's very consistent when displaying different scenes; however, it isn't bright enough to deliver a good HDR experience.
We measured the HDR peak brightness after calibration with Game Mode set to 'Off' and Color Temperature set to 'User'.
The Lenovo Y27q has great horizontal viewing angles. Images remain accurate when viewed from the side, good for sharing content on your screen or playing co-op games.
The vertical viewing angles are mediocre. This means you may lose image accuracy if you mount the monitor above eye level.
Our Lenovo Legion Y27q-20 has excellent gray uniformity; however, this can vary between units. The sides appear darker, especially at the top corners, but there's minimal dirty screen effect. Uniformity is much better in dark scenes.
Black uniformity is poor, but this can vary between individual units. There's visible backlight bleed, and the screen looks blue/gray, with some areas exhibiting a reddish tint.
Out of the box, the Lenovo Legion Y27q-20 has exceptional accuracy. All colors are accurate and white balance is nearly perfect. The color temperature is just a bit on the cooler side, giving the image a slight blueish tint. Gamma follows the sRGB curve almost perfectly, but some dark and bright scenes are over-brightened. Note that the sRGB mode we used to measure accuracy is a separate setting from the picture modes. We enabled the sRGB mode with Game Mode (picture mode) set to 'Off'. Finally, color accuracy can vary between units.
Accuracy doesn't improve much after calibration since it was already exceptional out-of-the-box. The color temperature is closer to our 6500K, but gamma remains relatively unchanged.
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 due to manufacturing tolerances, even for the same model.
The Lenovo Legion Y27q-20 has an exceptional SDR color gamut. It has full coverage of the commonly-used sRGB color space and excellent coverage of the Adobe RGB color space used mostly for photo editing.
Exceptional SDR color volume. It only has difficulty displaying dark colors due to its low contrast ratio.
The Lenovo Y27q-20 has a decent HDR color gamut. It has decent coverage of the DCI P3 color space used in most HDR content, but its Rec. 2020 coverage is just okay.
Our DCI P3 measurement is lower than the advertised 98% due to the way we measure the DCI P3 coverage. We measure it by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors to the DCI P3 primaries. This results in a lower but arguably more accurate measurement.
Mediocre HDR color volume. It has trouble displaying very bright colors due to its low HDR peak brightness, and it doesn't display dark colors well because it has a low contrast ratio.
There are no signs of image retention; however, this can vary between individual units.
The Lenovo Y27q-20 has superb gradient handling. You shouldn't see any banding in most content.
There's a tiny amount of color bleed, but it shouldn't be visible in regular content.
The Lenovo Legion Y27q-20 has good reflection handling. The matte anti-reflective coating does a good job of reducing the intensity of reflected lights. You shouldn't have any visibility issues unless you're in a very bright room with direct sunlight.
Text clarity is decent. Windows ClearType (top photo) makes diagonal lines look better, such as on the R and N.

The Lenovo Y27q-20 has exceptional response time at its maximum refresh rate, resulting in almost no blur trail behind fast-moving objects. The best overdrive setting is 'Normal' because the 'Extreme' option adds far too much overshoot, causing inverse ghosting.
| Overdrive Setting | Response Time Chart | Response Time Tables | Motion Blur Photo |
| Off | Chart | Table | Photo |
| Normal | Chart | Table | Photo |
| Extreme | Chart | Table | Photo |
The response time at 60Hz is excellent but noticeably blurrier than at max refresh rate. The best overdrive setting is 'Off' because there's too much overshoot with the 'Normal' and 'Extreme options. This means that you may have to change the overdrive setting if you're playing closer to 60fps.
The Lenovo Y27q-20's backlight is flicker-free, which helps minimize image duplication and reduce eye strain.
The Lenovo Legion Y27q-20 doesn't have a Black Frame Insertion feature.
The Lenovo Y27q-20 supports FreeSync natively to reduce screen tearing when gaming. It's certified as G-SYNC compatible, but it only works over a DisplayPort connection. The refresh rate is limited to 144Hz over HDMI.
We ran into some issues with VRR over an HDMI connection where the monitor would randomly disconnect and lose the signal. Resetting the VRR pairing (handshake) resolved the issue in our case, but we aren't certain that it would work every time since it happens randomly.
The Lenovo Y27q-20 has an exceptionally low input lag, providing a responsive desktop and gaming experience. We're unable to provide an input lag measurement because we lack the necessary tools to measure the input lag with HDR over a DisplayPort connection. Over HDMI, we can only achieve a maximum refresh rate of 75Hz at 1440p with 10-bit HDR with the tools that we have. However, you can achieve a 1440p @ 165Hz signal with 10-bit HDR over DisplayPort.
The Lenovo Y27q-20's resolution and size are great for work, gaming, or media consumption. The 27 inch screen provides plenty of space for multitasking and delivers an immersive gaming experience. It has a high pixel density, so images and text look sharp.
Update 12/09/2020: We've retested the HDMI input and changed the version from 1.4 to 2.0. We've also retested the 3.5mm analog audio port and can confirm that it's a combo port that can be used for both audio output and mic input.
There are few additional features on the Lenovo Y27q-20. It has a Dynamic Contrast Ratio (DCR) to improve the contrast, a Dark Boost feature to make objects more visible in dark scenes, and a Low Blue Light filter to reduce eye strain.
