Oh no ... really? It's happening on this monitor too? I have the Dell 2740L as well which has this issue and I thought it wouldn't happen to this model. It's really bad on the 2740L, and Dobr and nokey (another post thread) captured the exact way it shows up in photos on the U2413.

Can anybody PLEASE help, this has been driving me absolutely nuts. I keep losing my internet connection for no apparent reason. The connection will fail for a few seconds and then reconnect.

Most keyboards have a handy key that performs the logical equivalent of a mouse right-click on whichever screen item currently has focus (no mouse involved). The right-click usually brings up a context menu, of course.
