show – Can I scale my 2560×1440 display by 66% to fake to be 4K?


At dwelling, I’ve a 4K monitor with 3840×2160 which I exploit at 100% scaling. At work, I’ve a 2560×1440 LS27A600N display which is similar bodily measurement, however the home windows and textual content are annoyingly big as a result of the less pixels are bigger.

I would like macOS to drive the 1440p display at full decision however to use a 66% scaling to the desktop, making it mimic the 4K 2160p display: textual content and the window borders seem the identical bodily measurement as on the 2160p 100% scaled display, although blockier – one thing each Linux and Home windows can each do trivially. (And Apple Distant Desktop, sarcastically.)

Abstract as of Ventura: macOS seems incapable of scaling the native desktop down from 100% on exterior screens, to allow them to match extra textual content with out messing with the applying settings, and there are not any third-party instruments to do it.

Facet word – the inbuilt laptop computer display shows at 200% scaling: it might in precept show 4x the knowledge, however Apple would not care that you simply may need to do this both.


Earlier stuff, not so related now:

It is not about resolutions as such, it is concerning the visible font measurement and window decorations: I’ve ‘more room’ set for each the 4K and the inner display. I would like comparable default font and window ornament bodily sizes as I get on the 4K display showing on the 2560×1440 display, even when which means the letters are a bit blocky or extra clearly anti-aliased.

If I maximise my terminal window on my 4K, I get 545×143 and the scroll bar and title bar are about 2 characters excessive/broad (clearly, I hardly ever use it that enormous!). If I drag the terminal window to the built-in display, the font is… mainly the identical, a bit greater. On the 2560 display, it feels just like the letters are almost twice the bodily measurement of the 4K ones in the actual world as measured in precise cm or inches, not simply relative to the dimensions of the display.

If I set ‘default for show’ scaling for the 4K display my terminal window will get a laughable 268×72 characters for a similar font setting (Andale Mono 12).

So it appears I would like ‘much more area’ or ‘stupidly a lot area’ for the 2560×1440 display (and ideally the inner display), however Apple will not present that. Ideally, I might be capable to inform it ‘efficient decision’ (4K or higher) and have it scale that all the way down to the native display decision.

Sadly (for the query, luckily for me) I am in Berwick for a couple of month, so I haven’t got entry to the 2560 display. I will see if I can borrow one.

On the Samsung LS27a600n 2560×1440 at work, the Andale Mono 12 provides a terminal of 362×96 characters. I can clearly get 545×143 if I cut back the font measurement for the terminal, however – as I say – the purpose is that I would like this efficient scaling for every little thing on the display, so Andale Mono 12 would give a rattling good approximation to 545×143 and all the opposite functions (Slack, Chrome, and so forth) and window boundary controls could be equally scaled.

I’ve up to date to Ventura and there may be nonetheless no choice to scale the graphics to 66% on the display, to make 1440p behave like a barely fuzzy 2160p display. Linux can do it, Home windows can do it. Apple – incapable.

I discovered Show Override PropertyList File Parser and Generator with HiDPI assist which purports to let me overscale the display, but it surely’s not for 12.6.1 and issues are somewhere else – UID and PID – and specifically there is not any key to allow HiDPI (which I presume is important)

I attempted it and used the recommended command-line instrument (since I can examine it for safety) however no cube – it seems to be prefer it’s ignoring the brand new plist (which has 9 settings) and the decision changer exhibits one thing like 40.

I assumed I might ask in case there’s one thing extra official (or in case another person wants the reference).

I do not care about fonts trying a bit crappy, I care concerning the efficient show measurement.

Replace: 12.6.1 (21G217)
