Our Verdict
Dell Alienware AW3423DW
MSI MPG 341CQPX QD-OLED
The Dell Alienware AW3423DW and the MSI MPG 341CQPX QD-OLED are 34-inch ultrawide QD-OLED gaming monitors. You may prefer the Dell if G-SYNC Ultimate support is important to you, as only the Dell has it. However, the MSI is the better choice for most people, as it has a higher refresh rate for smoother motion, HDMI 2.1 bandwidth, and USB-C connectivity with a KVM switch for productivity.
