Blank Screen Improvement Suggestion

I run a leased access tv channel and I change my programming remotely via logmein pro by turning on blank screen and switching the programming behind the black curtain i.e. blank screen

My suggestion or rather question is would it possible to change the blank screen to a different image or be able to add text to the black screen?

So that those on the other end, whether it be a tv channel or another computer monitor could see something besides the black screen of death. . . . . Maybe? Possibly? Kind of? Sort of?
