The MSI MAG 321 X24 QD-OLED gaming monitor with 5-layer tandem technology has now been completely detailed by MSI, revealing specifications that are likely to make the product an exciting offering in the segment.

MSI has revealed the detailed specifications of yet another brand-new gaming monitor, dubbed the MAG 321UP X24. With an OLED display and support for high refresh rates, the fresh arrival is definitely an interesting addition to MSI's growing list of monitors.

The MSI MAG 321UP X24 packs a 31.5-inch panel based on 3rd gen QD-OLED technology. This tandem OLED panel sports a 5-layer design, which should allow for great longevity and brightness performance. Moreover, MSI also claims that its "DarkArmor" film manages to enhance blacks by as much as 40%.

MAG 321UP X24: 5-layer tandem QD-OLED display for excellent performance

The X24 gaming monitor features a resolution of 3840 x 2160, and a peak refresh rate of 240 Hz. Unsurprisingly, the primary benefits of OLED panels are all present, including but not limited to inky blacks, near-instant response times, and excellent color reproduction. MSI claims 99% coverage of the DCI-P3 color gamut, with Delta E of less than 2.

In simpler terms, if MSI's claims are considered to be true, the MAG 321UP X24 gaming monitor should be outstanding when it comes to picture quality. Its peak HDR brightness of 1300 nits is also plenty for almost any use case, although its full-screen brightness is unclear as of this writing. Based on the specifications we have so far, it would be safe to assume that the X24 should be more than capable of handling gaming as well as creative workflows.

The I/O on offer, however, is acceptable at best, featuring the following ports:

  • Dual HDMI 2.1
  • DisplayPort 1.4a (HBR3)
  • USB-C (w DP, 15-watt power delivery)
  • Audio jack

Other features, pricing, and availability

The built-in stand allows for ergonomic adjustments as well, with 30º to -30º of swivel, -5º to 15º of tilt, and 10º to -10º of pivot. Height adjustment is also possible, up to 110 mm. Other features include adaptable aim dot, Optix Scope with built-in magnifier, and other gaming-focused features. Features designed to extend the life of the OLED panel are also present, with the typical arsenal featuring pixel shift which utilizes screen detection, boundary detection, taskbar detection, and more. 

Pricing and availability details are not clear as of this writing, although more details should come out in the coming weeks. For those who need a premium gaming monitor right away, the Asus PG32UCDM 32-inch 4K OLED might be a decent option, currently available for $999 on Amazon.
