SmartSDR and Windows settings for us tri-focal folks ?

SmartSDR looks superb on my 27 inch 4K monitor if all I am looking at is the panafall.

In the two short weeks I have owned a 6400 I have yet to find a good way to comfortably view the small detail on the SmartSDR screen while also wanting to view signals across a 200-300 KHz bandwidth . The frequency bar between the spectrum display and waterfall takes a few seating adjustments, so do the various options in the radio panel. Same for Settings , DAX panel and also CWX. I assume the size of the text in those area cannot be changed to suit the user ? I have tried changing the PC's display resolution but it makes little difference to text within SmartSDR. Anyone got tips for this ? I am getting a bit tired of squinting, trying different glasses, moving my head and my chair.
