a question about maximize

Hello guys,
I am trying to maximize my windows to fill the whole screen of my computer. But the code:
“Maximize 100 100”
can’t work as I want. it only resize windows to fill a partial screen in the middle but not the WHOLE.
What should I do?

If use have panels or docks, you have to use

Maximize ewmhiwa 100 100

I see
Thanks very much:)

You can also set ‘EWMHBaseStruts’.
