Thanks for bringing this to meta. I am wondering if perhaps this comes from a version difference issue. The original question is asking about Premiere CS6. Both ProfessorFartSparkle and I verified independently that CS6 does the full screen preview which is not what the user was asking for. It may be that CC has changed that behavior. I do think that it would be a legit answer to the question to explain that it is not possible in CS6, but is possible in CC though. If you'd like, we can also discuss this more in chat (or here if you prefer) as it seems like a lot of the issues may just be based around misunderstandings. I do very much want to see the issue resolved to everyone's satisfaction.
It also seems that part of the problem may be that the original question had been clarified in the comments to my answer and I was working off of memory of the question and didn't realize that the details from the comment never made it back in to the original question. Given that, I do now think that your question did answer the question as it had been originally stated, so if you still want it undeleted I would be happy to do so for you, but the clarification in the comments on my answer (which I have since moved up in to the original question) do make your answer specifically not applicable (and still the full screen preview that the original question had said wasn't what was being looked for.)
