Provide option to set resolution of external display when in slide show mode
Currently, when Powerpoint switches to slide mode it ignores the established resolution with an external monitor and attempts to handshake and figure out the resolution itself. On certain switching equipment (Crestron, Extron, etc.) it is unable to establish the maximum resolution and defaults to the lowest. At this point there is no way to increase the resolution. In the Windows version there is an option to set the resolution. The suggestion is to add this to the Mac version. Alternatively (or in addition), it would seem logical if Powerpoint did not try to determine the resolution when entering slide show mode.
