Assuming no sync pulses on the color lines, and assuming black==blank, then in practice the GPU is driving 0V to 0.7V outputs, and that's either exactly what the monitor wants, or for the very rare monitors using the NTSC voltage levels, it's a teeny bit shy of the nominal 0.714V high level, but still well within tolerance so who cares.
Okay I'm going to stop dissecting VGA now, I promise I'm done. I can pop one layer back up the stack, compute resistors for the VGA DAC.
