MSI MAG 321UP QD-OLED X24 vs ASUS ROG Strix OLED XG32UQDMS Comparison
The MSI MAG 321UP QD-OLED X24 has a slight edge overall, mainly because it combines 4K 240Hz QD-OLED performance with higher listed peak brightness, DisplayHDR 500 True Black, USB-C video input, 15W power delivery, and KVM support. The ASUS ROG Strix OLED XG32UQDMS is extremely close, adding G-Sync compatibility, USB-A ports, Multi-View, and a broader set of gaming controls. Both deliver the same 31.5-inch 4K QD-OLED panel class, 240Hz refresh rate, and 0.03ms response time. Choose the MSI for connectivity and HDR brightness. Choose the ASUS for its broader gaming features and G-Sync support.
Both monitors use a 31.5-inch 4K QD-OLED panel with 240Hz refresh and 99% DCI-P3 coverage, so their core image quality is very similar. The MSI lists a higher 1300 cd/m² peak brightness and DisplayHDR 500 True Black, compared with 1000 cd/m² and DisplayHDR 400 True Black on the ASUS. The MSI therefore has the stronger specification for bright HDR highlights.
Neither monitor gives up much for high-speed gaming: both support 4K at 240Hz with a listed 0.03ms response time. The ASUS adds NVIDIA G-Sync support, Shadow Boost, Dynamic Crosshair, and GameVisual controls, while the MSI provides Adaptive-Sync, AMD FreeSync, Console Mode, and gaming assistance features. The better choice depends on your graphics card and preferred gaming tools.
This is one of the clearest differences. The MSI adds USB-C video input with DisplayPort Alt Mode, 15W power delivery, and a KVM switch, making it more useful for a laptop-and-desktop setup. The ASUS instead provides two USB-A ports and Multi-View, which can be more useful for connecting peripherals and viewing multiple sources.
Both displays include OLED protection, burn-in protection, thermal management, a custom heatsink, height adjustment, swivel, tilt, and VESA mounting. MSI adds a graphene cooling film and OLED Care, while ASUS offers OLED Care Pro, a proximity sensor, and additional features such as Uniform Brightness and Clear Pixel Edge. Both are well equipped for long-term OLED use.
