analog..looked it up in the books..as well as did what you gusy said..still have the first three blacks as deep black..can't see the diff. In the cmy color bars.. The cyan is slight, the magenta's first two bars are the same and the first three of the yellows completely the same. The rgb's all have the last two bars as same black.. the Whites in all are bright white. There isn't any problem with the lighter shades. I've gone the brightest as I can... have a satellite 1110 toshiba... help. It's two years old..but been kept pretty well..
