Internally, the monitor configuration functions use the Display Data Channel Command Interface (DDC/CI) to send commands to the monitor. Python脚本 虽然有点不科学,不过先写了一个C的程序,实现了亮度的更改。然后,对着ctypes文档翻译成Python即可。如果使用了奇怪的转接头,或者VGA这种接口,大概率是不能用的。

incremental development can save you a lot of debugging time. The key aspects of the process are: 1.Start with a working program and make small incremental changes.At any porint,if there is an error,you should have a good idea where it is. 2.Use temporary variables to hold intermediate ...
