Display Screen on Model

Hello forum,

I want to have computerscreens which can display stuff for me. So I have made a computer model with a flat spot on it where I want to have some stuff displayed. Now I already tried to use a 3d bitmaptext but this is only text. I want a fully controlable screen so I can even change the color of every pixel on it. And with pixels I mean rather large pixels because the computers have to look kinda oldish. So how can I apply an interactive screen or rectangle where I can display text and images on and control pixels and so on?

Kind regards!

possibly this helps:

Or you need to try Render to Texture example in JMETests.
