Tmux viewport caused by multiple concurrent sessions

Question

When attaching to the same tmux sessions from multiple computers using ssh and tmux attach, my screen looks like:

-------------------------
$>              |........
                |........
                |........
                |........
                |........
-----------------........
.........................
.........................

I was wondering if there is a command to get rid of the viewport

Answer 1

Probably the width/height (colums/rows) of the "original" terminal form which you launched te tmux session is lower than that of the terminal you're attacching from. Personally I don't use tmux, but that happens to me with screen when I launch from a 80x25 terminal and then I attach from another terminal with 80x50 columns/rows.
