Sort of, I think...

When MySQL is compiled, there is a buffer limit on how much crap you can
squirt through a single connection.

You can maybe alter this in my.cnf or be re-compiling MySQL.

If you are trying to push *THAT* much data through, though, you are
probably doing something fundamentally wrong in web design...

Okay, maybe for some kind of admin or debug or single-user screen...  Nah,
just use the mysql monitor for that.

Your numbers make me suspect that you are hitting a buffer limit, rather
than anything else.

Change the select (temporarily) to get a *LOT* less columns and see if the
limit changes.  If so, you can be pretty sure it's a buffer limit.

PS  If the browser appears blank, you haven't written any good MySQL/PHP
error checking.  Go do that *NOW*.  It will probably tell you *exactly*
what went wrong.
