Overview
Two 31.5-inch 4K QD-OLED panels, both running up to 240 Hz with 0.03 ms response, leave little to separate the MSI MAG 321UP QD-OLED X24 and the ASUS ROG Strix OLED XG32UQDMS on paper, so the MSI MAG 321UP QD-OLED X24 vs ASUS ROG Strix OLED XG32UQDMS decision comes down to brightness, connectivity and weight. The MSI is rated at 300 nits typical and 1300 nits peak, with 15 W USB-C and a built-in KVM. The ROG manages 250 nits typical and 1000 nits peak in HDR 400 True Black, adds two USB-A ports and has no USB-C at all. It is also lighter at 6.6 kg against 7.7 kg.

Verdict
Bottom line
Pick the MAG 321UP if you want the brighter QD-OLED at 300 nits with a built-in KVM and a USB-C input. Buy the XG32UQDMS if you game on an Nvidia card and prefer a lighter 6.6 kg body. For raw speed they match, so the deciding factor is KVM versus G-Sync support.
