The MSI MPG 321URXW QD-OLED is $749.99 at Amazon, which is $150 below the $899.99 MSI charges for the same white model on its own store. The cheaper price is also the slower one, because the Amazon listing says the monitor usually ships within two to four weeks while MSI shows it in stock.
That makes the crossed-out $899.99 unusually honest for a deal listing. It is not a dormant MSRP but the figure MSI is asking today.
The configuration is a 31.5-inch flat QD-OLED at 3840 x 2160, running at 240Hz with a 0.03ms GtG response time. MSI rates contrast at 1,500,000:1 and colour coverage at 99% DCI-P3, 97% Adobe RGB and 138% sRGB.
Amazon.com is both seller and shipper, and the listing is not Prime-gated. MSI also sells the black MPG 321URX for $859.99 on the same store, so the white finish carries a $40 premium at the maker.

The HDR claim, its window sizes, and what VESA actually lists
MSI’s specification page gives 250 nits for SDR. For HDR it gives 450 nits typical at a 10% window, labelled True Black 400, and 1000 nits typical at a 3% window.
Publishing the window sizes is the useful part. The Amazon bullets quote the 1000-nit peak and never say it describes 3% of the screen.
MSI is not consistent about this. Its cheaper 1440p models list a bare nit figure instead, as the MAG 272QP QD-OLED X24 does.
The certification itself needs care. MSI claims VESA DisplayHDR True Black 400 for the 321URXW on its specification page and in its own feature copy for this model.
VESA’s certified products list tells a narrower story. Its True Black 400 table names the MSI MPG 321URX QD-OLED at CTS version 1.1, with an empty family-models cell.
The letters URXW do not appear anywhere on that page. The white variant is not listed by name, and nothing published links it to the black model’s certificate.
Motion is separately rated VESA Certified ClearMR 13000, which counts clear pixels against blurry ones. That measure is part of why OLED motion clarity now gets compared with CRTs.
DisplayPort 1.4a, with no bandwidth figure attached
The video inputs are one DisplayPort 1.4a, two HDMI 2.1 ports and one USB-C running DisplayPort alt mode. MSI says all three carry 3840 x 2160 at up to 240Hz.
DisplayPort 2.1a is not among them. MSI does ship 2.1a at UHBR20 on its 27-inch MPG 272URX, according to that model’s specification page, but not on this 31.5-inch panel.
MSI publishes no bandwidth number for this monitor’s DisplayPort input at all. It states 48Gbps for the HDMI 2.1 ports, which is a smaller claim than the 80Gbps DisplayPort on rival 4K QD-OLEDs.
USB-C delivers 90W, according to MSI’s specification page, MSI’s store table and Amazon’s own bullet point. The Amazon title says 98W, and no other source supports it.
The hub behind it is modest. It is two USB 2.0 Type-A ports fed by a Type-B upstream cable, and the only audio connection is a headphone output.
Three years of burn-in cover, counted from two different dates
MSI gives a three-year warranty on this monitor that includes panel burn-in. The spec page, the store bullets and a store badge reading three years from the purchase date all say so.
Further down that same store page, the Monitor Service Policy gives MPG series monitors 36 months of repair service from the manufacture date.
The length matches at three years. The start date does not, and a unit that sat in a warehouse loses the difference.
The limits are stated plainly. There is no zero-pixel-defect warranty, a panel qualifies only past three bright dots or five dark dots, and the customer pays one-way shipping on a claim.
Prevention runs through OLED Care 2.0, which dims static taskbars, logos and image boundaries. MSI adds that those protections are disabled when the monitor receives variable refresh rate content, which is worth weighing against other 4K QD-OLEDs sold with three-year burn-in cover.
The stand, the sync support and what is not published
The stand tilts 5 degrees forward and 15 back, swivels 30 degrees each way and rises 110mm, according to the specification page. MSI’s store table says 130mm instead, and the two are not reconciled anywhere.
Pivot is 10 degrees each way, which levels the panel rather than turning it into portrait.
MSI names G-Sync Compatible as the only adaptive sync support for this model, and makes no FreeSync claim of any kind. It publishes no power draw figure, no Delta E row on the specification page and no DisplayPort bandwidth.
Digital Citizen has not priced this monitor before, so there is no earlier figure to measure today’s against. Neither Amazon nor MSI gives an end date for the discount, and prices at both can change at any time.
