The plausible aspect of the screen looks quite good to me, lighting is indeed the key to realistic scenes
Of course, a render shot in Max is never the same as when using the scene in 3dgs' WED. I see you're having problems with exporting this (which is the initial problem that scenes never look the same from Max to WED) thus I advice you to pm some experienced users about the exporting and compability functions from Max towards 3dgs.
Exporting can be a pain in the a*s when not using the right technique(s) ^^
