VCOM and waveforms are separate things.

Based on different things I read, my guess would be that VCOM is the voltage, and the waveform is the timing of when the voltage should be applied, when the inverted voltage should be applied and when no voltage should be applied. That's just guessing, though, the one thing I'm sure of is that VCOM is not the same thing as the waveform.

Interesting, I'll have a look at that.

Hm... that's interesting. Maybe it's not VCOM that's causing my issues. It it's not, though, I'm not sure what is.
