The MSI MAG 321UPX is Now Available – Differences with the MPG Model Explained

Share this content

We’ve had a few questions about this topic recently after we reviewed the MPG 321QRX. While there continues to be very limited stock of the MPG model, another very similarly named model is now starting to become more widely available, and appears to have a very similar overall feature set and that’s the MAG 321UPX. We thought it would be useful to run down the differences here in case you want to buy the MAG model sooner, and in case that suits your needs perfectly well.

Overall specs are the same

Both models are 32″ in size (accurately 31.5″) and built around the same gen 3 Samsung QD-OLED panel. They have a 3840 x 2160 “4K” resolution, 0.03ms G2G response time spec, 1.5 million:1 contrast ratio, 250 nits typical brightness (SDR), 10-bit colour depth and a wide colour gamut covering 99% DCI-3. They both come factory calibrated with a dE <2 listed.

Both have a 240Hz refresh rate which is supported by adaptive-sync for variable refresh rates (VRR) from compatible NVIDIA and AMD systems. They’ve both been certified under the ‘ClearMR 13000′ scheme. For HDR, both models have a peak brightness spec of 1000 nits and are certified under the VESA DisplayHDR 400 scheme as well.

For connectivity, both have 1x DisplayPort 1.4 with DSC, 2x HDMI 2.1 (with 48Gbps bandwidth) and 1x USB type-C (with DP Alt mode and power delivery – see below). Both have a headphone connection as well and have a fully adjustable stand with tilt, height, swivel and rotate adjustments. They both also feature the same wide range of OLED Care 2.0 protection features and come with a 3-year warranty which includes burn-in cover. They have a fan-less design with custom heatsink and graphene panel too.
