Windows 8.1, wrong DPI after undocking

[oscar]

Using a Dell D3100 with a Dell XPS13 (early 2015) wich has a high resolution display (3200x1800). I have two 24" monitors connected, both at 1920x1200 resolution.

When connecting/disconnecting to the dock, the DPI of the system is incorrect. For example, when docking the system, icons and text become HUGE. When I undock the system, icons and text become tiny. The only way that I've found to remedy the issue is to logout of Windows, and re-login.

Any ideas?

Unfortunately this is a "feature" of Windows at the moment. After changing the scaling you need to log out and back in - it does not change automatically. This happens in Windows 7 and Windows 8.
