I think it depends on the display driver installed. What is clear is that they err'd on the side of caution for a number of monitors "just in case", and that is merely conjecture. I have seen it before, but don't have it for my SyncMaster P2770 on this install. There is native driver support in Windows 8 for this monitor as well as a driver on Samsung's website. So what I'm saying is if they weren't sure, they may have just granted support for it. I know for a fact its not based on resolution, as some techs have suggested, because I'm in 1080P. Some have said if you have a high monitor resolution this appears, but I'm sure this is not the case.
Its probably based on the monitor driver and properties assigned to it. Most of these...
