It's been three months since we started our OLED burn-in test,Puri for Rent (2025) where we've been using the MSI MPG 321URX 32-inch 4K OLED monitor exclusively as a productivity display. In today's update we're going to talk burn in, firmware updates, and of course, some general usage impressions.

If you missed our first-month update, you may want to go back to get a full idea of the setup we're using and why we've decided to use this 4K 240Hz QD-OLED gaming monitor as a workstation display. But basically the idea is to perform a real-world test of OLED longevity in the worst possible configuration, effectively burning in the display on purpose.

That means we swapped our daily-driver 32-inch 4K IPS LCD office monitor for this new QD-OLED and changed nothing else about the setup – no dark mode or screensavers, or anything like that. This is to see whether OLED monitors really can be used as LCD-equivalent productivity displays long term.
