The Lenovo Legion Y27q-20 is an impressive gaming monitor that delivers incredibly smooth and responsive gameplay. It has an exceptionally quick response time and a 165Hz refresh rate, resulting in almost no motion blur in fast-moving scenes. Its input lag is low, and it has both FreeSync support and G-SYNC compatibility to minimize screen tearing. It has an IPS panel with wide viewing angles but a low contrast ratio that makes blacks look grayish in the dark. It has good ergonomics and allows you to adjust the screen to your ideal viewing position easily. It handles reflections well and gets bright enough to fight glare, so visibility shouldn't be an issue in most viewing conditions. However, it doesn't get quite bright enough to deliver a good HDR experience. On the upside, its color accuracy is remarkable out of the box, and it has an exceptional SDR color gamut with full sRGB coverage.

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.

Build Quality

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 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.

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'.

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.

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.

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.
