Product Snapshot

Overview

The Alienware AW3821DW is a high-end curved UHD gaming monitor, which was released in 2020, to provide an immersive experience to professional gamers. Featuring an exciting 144 Hz native refresh rate and Variable Refresh Rate tech, this monitor offers smooth, high-frame-rate visuals. It has a G-SYNC Ultimate certification and is compatible with FreeSync, providing tear-free imagery when paired with various AMD Radeon and NVIDIA graphics cards. The monitor has an incredibly low 4.4 ms input lag and 1 ms GtG super-fast response time for smooth visuals and split-second responsiveness. This gaming monitor is more ergonomic than the competing LG 38GN950-B and boasts HDR10 with outstanding peak brightness that brings HDR content to life. However, its mediocre contrast ratio and poor edge-lit zonal dimming prevent this monitor from attaining its true HDR potential. Read our full Alienware AW3821DW review and see how the display compares with the best-ranked computer monitors today.
