After about 1.5 months and many hours of gaming I can say that the QD Oled from MSI certainly gives a beautiful image and is a world of difference compared to a 27 Inch 1440P IPS panel.
The 0.03 ms response time and 240HZ refresh rate is really a game changer for me, hence the switch to this screen.
But unfortunately I also found a dead pixel.
You would expect that for the price of over 1K you would also expect a product where these types of defects do not occur or at least would be covered by the warranty.
MSI: from 3 bright pixels with a distance of 15 millimeters or 5 dead pixels. In other words, deal with it.
So if you are considering spending 1K+, keep in mind that a dead or fixed pixel can also occur on these types of top models and is therefore not covered by the warranty.
