And make it black is usually done in software (by memsetting the screen
with the black color).

Or by setting all color palette registers to black, if available, since
it's cheaper...

Ok. So, if pseudocolor/directcolor, set palette to all black, otherwise memset
the screen.

 Still not there -- some RAMDACs can be asked to do blanking themselves.  
And there are these interesting implementations like the Bt463 that have a
palette even though using the truecolor mode.
