Our Verdict
MSI MEG 342C QD-OLED
Dell Alienware AW3423DWF
The Dell Alienware AW3423DWF and the MSI MEG 342C QD-OLED both use the same QD-OLED panel and have many similarities, but some differences exist, too. The Dell has better PQ EOTF tracking, so the image looks more accurate on the Dell. However, the MSI has a few advantages in other areas, like its HDMI 2.1 bandwidth, which lets it take full advantage of gaming consoles, and its extra productivity features like a KVM switch and Picture-in-Picture and Picture-by-Picture modes.
