Dell E5450 - blank screnn on external monitor connected to dock station

Hello everyone

I've problem with my dell E5450

1. When i connected laptop with close cover to the dock station i will get screen on the external monitor.

2. When i connected latptop with open cover i've screen on external monitor and on the laptop.

Problem starts when i connected my laptop with close cover to the dock station then open them. 

I've only screen on the laptop but none on external monitor. I must use  keys combination like "windows + p" and choose  extent screens to display screen on laptop and external monitor but when i disconnected laptop from dock station and connect again that the same problem.

What can i do to solve this problem?

My configuration:

intel core i5-5300U 2.3 Ghz

Intel HD 5500

Windows 7 pro

Wow, Windows is usually very good about remembering the desired display configuration when you return to a particular combination of hardware. Is your graphics driver up to date? You can get it from support.dell.com.

Do you have newer driver?

Hmm, that's very different from the version number posted on support.dell.com.  You might want to try installing that version anyway since you can always uninstall it if you find that it somehow makes things worse.
