In the recently exposed Windows 8.1 build 9385, we found a screen to adjust the resolution function, you can adjust the different screen resolution.
Split-screen resolution adjustment
Now that the Settings window is displayed, the user can zoom in on the desktop element with a new slider, and it can be adjusted in a different split screen to allow the two display to appear at different resolutions. This has a higher degree of freedom for users who like to split the screen.
In fact, this feature was supposed to be implemented in previous releases, but there is always a bug that no matter how the resolution of the primary display is adjusted, the resolution on the other screen is always 100%. And now this function finally in Win8.1 normal implementation.
Windows 8.1 will bring a series of improvements, including the IE11 browser, the new Metro icon sorting and installation progress, and so on, and yesterday there was a message that Win8.1 will use Update update.
