How to scale landing page when players log into game?

Hello,

How do I scale my game's landing page, so players see the whole page when they log into the game?  

Here  is a screenshot of how I would like to look when players log in:

Not possible.  

Each player will control that, zoom of their viewport of the page, on their own. Best you can do is ask them verbally, or tell them in chat text, or print some text in the upper-left corner that instructs them "Zoom out to see the full page, I use 60%" or something social like that.
