Overview
The Lenovo L27-4r pairs a 27-inch IPS panel with a 165 Hz refresh ceiling, making smooth everyday and casual gaming use its clearest advantage. Its Full HD 1920 x 1080 resolution delivers 81 PPI, so the screen offers generous workspace but less fine detail than higher-resolution 27-inch monitors. The panel is rated at 300 cd/m², 1500:1 static contrast, 99% sRGB coverage and HDR10 support. AMD FreeSync and VESA MediaSync Display help reduce tearing, while the published response figures include 1 ms MPRT, 4 ms minimum and 6 ms average. Two HDMI 2.1 inputs, D-sub and a 3.5 mm output cover common sources, and built-in 2 x 3 W speakers reduce desk clutter. The lightweight stand only tilts, with no height, swivel or pivot adjustment. Buy it for high-refresh Full HD flexibility; skip it if sharp text density or full ergonomic adjustment matters more.
Key Highlights
- A 165 Hz IPS panel balances smoother motion with wide 178° viewing angles
- 99% sRGB coverage makes it more capable than a basic office-only display
- Built-in 2 x 3 W speakers reduce the need for separate desktop audio
- Two HDMI 2.1 inputs plus D-sub support both modern and older systems
- The 4-sided ultra-thin bezel suits compact multi-monitor layouts
- At 3.9 kg with stand, it is easy to reposition or mount

HDR & Brightness Reality
HDR10 support is present, but no DisplayHDR certification or separate peak-brightness figure is listed. With 300 cd/m² typical brightness and a 1500:1 static contrast ratio, the monitor can accept HDR content yet is unlikely to produce the bright highlights or deep black separation associated with stronger HDR displays. The IPS panel and 99% sRGB coverage are more meaningful for everyday colour consistency than the HDR label alone.
