Unfortunately, due to the novelty of Oled monitors, there is no real empirical data yet. As far as I have understood from various tests and analyses (RTings, Monitors Unboxed), the use of desktop apps (no matter which ones) for several hours a day would practically guarantee burn-in shadows in the display after 2-3 years.

If you take good care of the monitor otherwise (run Pixel Refresh when it reports it etc.), then I could imagine that you will only see it at all with light backgrounds and perhaps it will only appear after 4 years. However, burn-in is practically guaranteed sooner or later with this type of use.

That's why my Asus PG27AQDM is reserved purely for gaming and watching videos and is otherwise always completely black. This way, I hope to be able to use it for many years with consistent quality. And the quality is really impressive. Even RDR2 in the snow area looks incredibly good (although it dims down a bit there, but that's hardly noticeable)

For gaming AND programming or any form of desktop use, I would recommend a good mini LED monitor like the Cooler Master GP27 or the Samsung Neo G7.

If I understand you correctly, would you run Windows and programmes on your second monitor? I have been using the Asus for both (Windows and games) for several months without any problems! You can also do manual pixel refreshes if you're worried about burn-in, which I do every 2-3 weeks, but as I said, no guarantee as far as long-term use (i.e. several years) is concerned, but I haven't had any problems with it to date.

I do not recommend it as a main monitor and also not for programming, as there is a risk that it will burn in and, on the other hand, the letters are very distorted and look sharp due to the technology of the OLED itself. This problem is very big Currently common with OLED screens. However, if you only want to use it for gaming, it is highly recommended. Regards
