Creating a Computer Screen Material

Would like to make a material that has a picture in it that I can use as a computer screen. It is the lit part that I can’t make. Some programs use a “Constant” setting which just uses the exact colors of the picture to come thru and it looks very much like a screen. I usually end up doing it post process in photoshop but I want to save that step. :thinking:

It’s called “Emissive” at V-Ray (I use the PC version). Often I add a reflective coat for a better look.
