MPC-HC 2.0.0.7 auto full brightness

MPC-HC 2.0.0.7 in full screen automatically raises the screen brightness to maximum. When you exit the full screen, the brightness returns back. How to turn off auto brightness?

The player does not change the brightness. It is either Windows or your graphics driver that is doing that. Search those settings for dynamic brightness.

It turned out I was wrong. Somehow, it is in this player that there is a separate monitor brightness setting. There is no such thing in another player (bsplayer). I just set the brightness of the monitor below and it was remembered.

That brightness setting should apply to both windowed and fullscreen.

Where that option? How to turn that off?

It is already off by default.

So this is not it. The backlight of the screen changed, not the brightness of the picture.

I already said that brightness change is done by Windows or graphics driver.
