Set my monitor as default screen when connected to my Windows 7 notebook

Go to Start-->Control Panel-->Display, then click "Display Settings" on the left, and you will see settings for both displays including whichs hould be primary and secondary.

I don't have that screen.  Remember its Windows 7.

In control panel, there is 'Appearance and Personalization' , under that, there are 3 option Change Theme, Change Desktop and Adjust Screen resolution.  

If i type display 'display' on search i can access Change Display Setting but there is no option for primary / secondary

When you get to the control panel, in the top-right corner, change the view to "Large Icons", and you'll see all the individual settings

Just did it and 'Display' is shown, but when click, I get 'Make it easier to read whats on your screen'.,  And have 3 percentage smaller, medium larger.  But no Primry or Secondary

You missed a step -- once you are in "Display", you need to click "Display Settings" on the left

i did (see pic)

Where is primary/secondary?

Yes of-course, thanx!

Question... i use a menu/option apps called 'RocketDock' from PunkSoftware, when I succesfully make my monitor default, all the notebook windows content is transfer to my monitor except the RocketDock,

Please advice.

I don't know much about it, but since it's a program, not an actual toolbar, then you manually have to move it to the monitor. And it should remember which screen it was last set to, so the next time it launches, it should be on the monitor. However, you'll probably have to manualy move it every time up unplug/replug the monitor.

Ok... we'll check... thanx!

Thanx
