Btw, it's not "more or less" :) Whenever the resolution register is set to mono the Shifter immediately stops outputting data on the RGB lines and instead outputs on the MONO line. The RGB-pin's output level drops to the same level as for BLANK (which on an ST is lower than black, on an STE it's the same value as for black).

In theory this means that proper emulation should reserve a "blacker black" for BLANKing and MONO use, on ST, but I think it would suffice to just use black ;)

 - as you see hatari displays 4 more visible pixels than STF on the right, that's because the stabilizer is not emulated. If it were, the hi switch would indeed turn more pixels to black (more or less, it's the result of decoding bitplanes in monochrome during a few cycles). Hard to fix at the moment.
