Answer

Laptops with panels that support multiple refresh rates setup may experience momentary black screens when connecting or disconnecting the power adapter.

This black screen is considered to be a normal phenomenon due to the changing refresh rates that are meant to provide better power efficiency when the AC power is unplugged.

Power efficiency plays an important when it comes to laptops, and the higher the display refresh rate panel has, the more power the system consumes. When the power is disconnected, MSI Display Power Saver will automatically adjust the panel refresh rate down to 60Hz or lower (depending on the panel support) to help prolong the battery life and switched back to the maximum refresh rate when the power is connected back again for the best viewer experience.

To stop the power saving by setup or avoiding the momentary black screen when plugging/unplugging the power adapter, follow the steps below.

Disable Display Power Saving in MSI Center/MSI Center Pro

(*Note: Models that don't bundle with a higher refresh rate panel will not have such an option)

- MSI Center: Launch  MSI Center > Features > General Settings > Togged off the “Display Power Saver”

- MSI Center Pro: Launch MSI Center Pro > Setting > General Settings > Togged off the “Display Power Saver”
