this is not HP.com sorry, its a BULLsession blog, mostly guessing
QUESTION TO YOU.
no computer stated, 10000s exist, 1981 to now, endlessl....
we get you have a display connected to what>? who knows.
I hate guessing
but is display connected to a desk top PC?
so if you barrow and other display does it work ok?
it has 2 cable (not power) one is DVI other is VGA
which one are you using.
ok i see your confusiong
yes, the monitor has its one menu's and the bad designers
dont tell you that, all pop up windows need to say who is talking to you in this case "F2105" is not in the window.
geeks design it and this is what you get.
even windows 10 does this inane acts,, it pops up
and forget to say , I'm W10, only the blue color dark is the clue)
so dont feel bad, its the lame geek disease there.
what does this mean
that you need o learn the buttons on your monitor
one is to clear those screens its in the manual.
best is dont use those buttons. if possible. on side of monitor
the monitor has its own tiny computer brain that is helping you.
the button on most monitors (mine has 5)
menu button,. press one to get menu press again to exit
some have an exit button push it.
lost your manuals>? hp.com has them, ask.
your monitor has speakers, those need to be connected. to the PC.
the screen box is called, clear it now using manuals above.
On-screen display (OSD)
