in your modelling app (if you still can do this) remove the screen area, and save it as a seperate object, and save your screenless console aswell ( the console you would have to make a uv map and texture that seperately) , then bring both objects into poser, position the screen to where it is supposed to be on the console, then parent the screen to the console, 
 

 
To tidy it up a little further you can then export both the screen object and the console object to obj from Poser and re-import that new obj back into Poser as one single object. The material groups will still be named properly for the textures to work. May be a little extra step to take but if you had say, a half dozen or so different parts you can use that method to save them all as a single prop.
