Three months ago we reported on an interesting OLED burn-in test performed by a YouTuber called Monitors Unboxed, on an MSI MPG 321URX QD-OLED monitor. After this long 4,500 hours (18 months) deliberate testing, the results were that there's a continual, gradual degradation, but not a drastic effect. This was very good results, considering the test style.
Monitors Unboxed is now back, and they share the results of the test, that is now in its 21 month, or over 5000 hours of use - see video above.
The QD-OLED panel is now showring overall brightness degradation for the first time - but only 2%, from 243 nits peak brightness to 238 nits. Beyond the peak brightness slight drop, the existing burn-in artifacts that have been reported in the previous test, have only slightly worsened. This is a very good result, as real world usage will be far more easy on the monitor
