I've been messing around with gradients and the bottom one seems to be a lot smoother to me. All they are is red+green 0-255 and the bottom one has slight variations in blue that seem to help mask the steppy effect. If you could tell me your monitor type, model, connector (VGA/DVI/BNC), and which one appears smoother (less steppy) to you, that would be very helpful. If you can't tell a difference or only appear to see one gradient that's fine too. Thanks.
