Thats not how most (some will offer 10 bit color) digital televisions work. Each color (R/G/B) consists of 8 bits (that's why there are 256 shades of gray). Now, the bits are either on or off; doesn't matter what voltages are applied; depends on the processor. Plasma and LCD each work a bit differently in how they manage this of course. Anyway, were not converting volts or mV to binary, we're just turning each bit on or off. So again, if all three colors are set to the same bit level, 00000000 is black and 11111111 is white.
