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.

Overall, it works well with recent Mac’s. But if you want more information, you can find it in the relevant section of each review!
In the macOS Compatibility section, it doesn’t look like the Mac is recognizing the variable refresh rate capability of the Alienware, as compared to the MSI screenshot on the left. Does the Alienware actually support VRR with a Mac?
