[DUG] Screen Resolution and WIndows 10 settings and Delphi

[John Bird]

Looking at high resolution screens – external monitor and replacing laptop i.e. going to 3840x2160   instead of 1920x1080
I have seen one and its nice, under display settings in Windows 10 it had “Change the size of text, apps and other items” set to 300%
Questions:
  1.. What is this setting doing?  
  2.. Is it different from Windows 8 which had a scaling factor (eg 125 DPI) which could be set and would create issues with many programs such as Delphi 2007  IDE   (e.g. some dialogs could not fit their items within the borders )
  3.. How well do older Delphi (e.g. D2007) programs and IDE play in such a high setting (300%)
  4.. How well do latest Delphi (e.g. 10.4) programs and IDE play in such a high setting (300%)   - as I have both versions of Delphi active
Any comments from those working with such great big screens please on tips and pitfalls
