Bear in mind that as long as you use MSI's Care technologies, the company offers a 3-year warranty to its OLED panel monitors, and while Panel Protect was a good feature, the 16-hour limit was not that great and could be annoying. Now, MSI has pushed the limit to 24 hours, when the screen is active for more than 4 hours.
MSI Panel Protect also forces the Pixel Refresh, but only if you have decided to skip the refresh four times, removing the skip option.
The new update will require a firmware update, and you can find more information over at MSI's website.
