Well, you could make it a text app, and have it force its session to
the foreground.  But that may suspend some apps, especially DOS ones.

I think there is a video IOCTL you can send which will just turn off
the screen.  Perhaps by setting all the palette registers to zero.
This might work.

Use start, not detach.  Your screen blanker generaes output, and I
don't think detach will work with such a program.  If you app is a
text-mode app, it will get a window, which can be hidden.  If it's a
PM app, it will not show any output until you create windows, so it
can run hidden if you want.
