I'm not seeing any pics on my end : /

I think it's the lack of reflection on the screen that's bother me the most. Try putting in a HDR map in the environment slot in mental ray and see if you can't get some reflections going with your materials.

increase the self illumination of the screen until you can see it. you may need to raise the value into the thousands before it is visible.

also the reason your render is looking unrealistic is probably more to do with bad material definition. FG settings have very little to do with it. Infact 90% of the settings you've posted deal with producing a clean final render... not a realistic one.

Get a HDR in there. make sure your using photo-metric lights. the standard max lights are rubbish for realistic renders.

also some contact shadows would really help. (mip matte shadow would be great here)
