Make the portal pages 16:10 - not 4:3
This is the 21st century. The majority of users are using screens in a 16:9 or 16:10 aspect ratio, or will shortly do so. Why should a newly launched (!) portal be 4:3, and crop vital column contents e.g. in the "Products" section("PI Connector fo…"), rendering the whole page useless? Who would ever browse a support portal from their smartphones?

Aspect ratio is not the issue. The width of the content relative to the width of the page is the issue.
I think that the better, more general improvement would be for the pages to be "responsive" (i.e. adjust according to the window size) and take advantage of the full screen space.
