Our Verdict
Dell Alienware AW3420DW
LG 34GP83A-B
The LG 34GP83A-B is better than the Dell Alienware AW3420DW for most uses. It has a higher 160Hz refresh rate compared to the Dell's 120Hz, and its response time is significantly better. Also, its higher peak brightness makes it more ideal for well-lit rooms, and it supports HDR. The Dell has better ergonomics because it allows for swivel adjustment, and it has more USB ports. In terms of VRR support, the LG is compatible with FreeSync and G-SYNC, while the Dell has native G-SYNC support and FreeSync compatibility.
