If you’ve been considering an OLED gaming monitor but have hesitated because of fears about burn-in, you’re not alone. Permanent image retention has long been the biggest worry for potential OLED buyers. That’s why long-term real-world tests, like the one conducted by the team at Monitor Unboxed (MU), are so valuable.
Back in September, we covered MU’s 18-month check-in on the MSI MPG 321URX QD-OLED. The results were promising: after 4,000+ hours of mixed use, burn-in was present but mild—likely not a deal-breaker for the average gamer or multimedia user.
Now, MU has released their 21-month update, pushing the monitor past the 5,000-hour mark. The big question: has the burn-in situation escalated, or does this QD-OLED panel still hold up? Let's dive into the latest findings.
The 21-Month Stress Test: What’s Worse, What’s Stable
After 21 months of continuous use—simulating a punishing routine of work and play with no burn-in reduction features enabled—the monitor has naturally degraded further. The areas previously showing wear have become more pronounced.
- The Usual Suspects: The most visible artifacts remain the Windows Taskbar, the divider line between side-by-side apps, and a patch on the right side of the screen where a static application lived. This pattern confirms that static user interface elements are the primary culprit for burn-in on any OLED display.
- Sub-Pixel Breakdown: Consistent with the 18-month report, the Green sub-pixels are degrading fastest, followed by Blue, then Red. This uneven wear can subtly affect color balance over time, though it's often only visible in specific test patterns.
- A Win for Color Temperature: Despite the pixel wear, MU reports that the overall color temperature of the MSI MPG 321URX has remained stable, with no further deviation. This is a positive sign for color accuracy over the long haul.
A New Development: Maximum Brightness Takes a Hit
For the first time in this marathon test, the monitor’s peak brightness has measurably decreased. It now tops out at around 237 nits, a drop of about 5 nits from its original output.
While 5 nits is a tiny change imperceptible to the human eye, it marks a turning point. OLED panels naturally dim as they age, and this suggests the gradual decline in brightness—a separate process from burn-in—has begun. It’s reasonable to expect this slow decrease to continue with further use.

The Bottom Line After 5,000 Hours: Should You Still Buy It?
Here’s the most crucial takeaway: after 5,000 hours of extreme, abusive testing with only 576 automatic compensation cycles (far fewer than a normal user would run), this monitor is far from destroyed.
The burn-in is real and has progressed, but it remains largely in the context of a stress test. For an average user who enables the built-in pixel cleaning routines, varies their content, and doesn’t leave static elements on-screen for 12+ hours a day, the experience would be dramatically better.
Verdict: If you’re an average gamer or multimedia user who wants stunning OLED contrast and response times, the MSI MPG 321URX QD-OLED still presents a compelling case. Based on this real-world data, you can confidently expect three to four years of heavy, mixed use without noticeable burn-in impacting your experience. The gradual brightness decline is worth noting for those who plan to keep a monitor for half a decade or more, but for most upgrade cycles, it shouldn’t be a primary concern.
