David, we have our guys looking into the issue. We're trying to see if we can reproduce the problem in house. Unfortunately I was able to get my Full Screen to work. I didn't turn on the 4k option. I'm afraid you will need to choose one at a time. Being able to choose between the 3 didn't make it into the patch. Yellow, I believe that this is the last one we're going to be able to do. If there are any glaring issues with this patch, we'll try to get that fixed, but we just don't have the time or resources right now with working on that thing we can't talk about.
