look at this picture:

its obvious that 256 shades per channel is not enough when will there be monitors and videocards that can display more than that....maybe it already exist but i cant find any information about it

10-bit GigaColor technology :thumbsup:
For 3d, it's quite a slow card (=geforce 4)but for 2d... it should be your choice.

24bit color = 16.7 million colors
64bit = ?

I've read that the human eye cannot discern over 16.7 million colors. Not even close to that.

Does 64 bit video refer to increased luminosity range? If so, would you not also need a monitor capable of showing that, like the HDRI displays under development?

Sorry, to leave your question with another, but I don't understand why anyone would need to develop 64bit color.

saw a display at siggraph that was touted as an hdri display. So yes they exist. As far as that rendered image the issue is not the actual display, the issue is the rendered quality that is screwing up the gradient. If you do up that same spere in maya, render it to 32 bit float in mental ray, spit it out to shake and view it in shake. The gradient will be absolutly perfect. So the problem isn't the display/graphics card/ computer its the internal rendering color depth.

I'm not to sure though that the additional precision in color display will be displayable with current equipment in any meaningfull way.
