如果您发现在 Windows 11 或 Windows 10 游戏平台上全屏玩全屏游戏时显示器屏幕变暗，那么这篇文章是为您准备的。在这篇文章中，我们将确定问题的潜在原因以及最合适的解决方案。
为什么我的电脑屏幕一直变暗？
导致屏幕亮度变暗的最可能的罪魁祸首包括：
- 默认启用的自动调光设置。
- 省电设置。
- 损坏的 GPU。
- 过时的驱动程序。
此外，主要在笔记本电脑上还有一项称为自适应亮度(Adaptive Brightness)的功能，它可能会导致 Windows PC 上的屏幕变暗。该功能的工作方式是，传感器将检查房间周围的环境光——如果光线发生变化或传感器检测到环境变化，它将相应地调整屏幕亮度以适应光线水平。
为什么玩全屏游戏时屏幕一直变暗？
Windows 10/11上玩游戏时，您的 PC 屏幕会变暗，因为Windows可以根据到达系统环境光传感器的光量来调整显示器的亮度。您可以在OSD（屏幕显示(Screen Display)）菜单上将按钮切换为打开或关闭选项自动调整我的屏幕亮度。(Adjust my screen brightness automatically)
