Hello,

I suggest trying the following methods:

• Window resizeTo(): This method resizes a window to the specified width and height (in pixels). The syntax is: window.resizeTo(width,height)
• Window resizeBy(): This method resizes a window by the specified amount (moves the bottom right corner of the window by the specified number of pixels defined. The top left corner will not be moved). The syntax is: resizeBy(width,height)

You can test these methods in our HTML5* Playground

.

Moreover, I suggest checking the following article for additional technical background Developing HTML5 Applications for Intel AppUp(SM): Part 1 A Simple Example.

As Marvin suggested; I've used window.resizeTo() to resize my apps' windows size and it workes perfectly :)
