Setting monitor PPI in Indesign 2020? Show 1:1 pixels on a 2010 iMac

[Palm Equipment]

Hello,

I am drafting some website wireframes in indesign 2020.
My document size is set to 982 x 1200 pixels with rulers set to pixels.
When I set 'View > Actual Size' the page displays too large.
My monitor is a 2010 iMac with a PPI of 108
I have to scale the view to 66.666666% to get a 1:1 view of my document.
Is there a way I can get Indesign 2020 to recognise the 108 ppi of my monitor and show 1:1 pixels at View > Actual Size?
(Just like I can set Photoshop Preferences > Units > Screen Resolution)

My apologies if this has been asked before on the forum ... I have read so many conflicting claims online about this in Indesign.

Regards, Peter

As a bonus tip, is there a way to set monitor ppi in Acrobat DC so that shows 1:1 pixels at 'actual size' too?

Why in the world of responsive sites and mobile devices would you even attempt to do this with InDesign? There are far better tools for this.

InDesign has a preference that lets you set a custom monitor resolution, that is not available via the UI, but can be scripted. So this JS sets the 100% zoom to 1:1, which was the zoom scale prior to CS6:

app.generalPreferences.customMonitorPpi = 72;
app.generalPreferences.useCustomMonitorResolution = true;
app.activeWindow.zoomPercentage = 100;

If you need to set the zoom back to the default where 100% equals the 100% print output view use this:

//reset to print
app.generalPreferences.useCustomMonitorResolution = false;
app.activeWindow.zoomPercentage = 100;

If you want to do the same in Acrobat set the Page Display Custom Resolution Preference to 72ppi with no documents open.
