windows and objects have fixed sizes in pixel. My understanding is, if

images get blurred, when being scaled, so you shouldn't enable this

when you use images, correct?
Hi-DPI scaling makes it so that if the systems 'pixel scale' (the
mapping from virtual pixels to physical pixels) is not 1-1, the engine
will appropriately render things to use the 'extra fidelity'.
A stack which is 400x400 in LiveCode, will still appear to be 400x400 on
a Retina display, say, except that it will actually be rendering at
800x800 - making things crisper.
Depending on the version of Windows you are targetting, you can
experiment with HiDPI by adjusting the 'text scaling' option in the
system preferences.
Why is the Hi-DPI support for Windows a chooseable option and for OS X
it is
standard since 6.7.6 (6.7.7)? Do images don't get blurred, when the
stack is
resized on OS X? Why can't I disable this option on OS X?
Windows does not allow the runtime configuration of Hi-DPI 'pixel
scaling' - it has to be specified as part of the Applications 'manifest'
which is integrated at standalone build time.
Mac, however, does allow toggleing configuration of Hi-DPI 'pixel
scaling' at runtime - see the 'usePixelScaling' option.
By default, the Mac engine will use as many pixels as it can - so if you
have a retina display, you will get pixel scaling (but you can turn it
off - set the usePixelScaling to false).
On Windows, by default pixel scaling is turned off, but you can choose
to use it for your app by turning it on in the standalone builder.
Warmest Regards,
Mark.
