macOS Scaling:
<ul>
<li>Uses pixel doubling (“Retina”) technology for sharp displays</li>
<li>Renders at native resolution, then scales UI elements proportionally</li>
<li>Default scaling maintains crisp text and graphics without pixelation</li>
<li>Limited built-in scaling options (requires third-party apps like BetterDisplay for fine control)</li>
</ul>
More consistent experience across applications
Windows Scaling:
<ul>
<li>Uses percentage-based scaling (125%, 150%, etc.)</li>
<li>More granular control over scaling without third-party software</li>
<li>Can suffer from inconsistent implementation across applications</li>
<li>May result in blurry text or interface elements in non-optimized apps</li>
<li>Better support for multiple monitors with different scaling needs</li>
</ul>
Both systems attempt to solve the same problem (high-DPI displays) but take different approaches, with macOS prioritizing visual consistency and Windows offering more flexibility.

I post all the articles I read and find interesting myself.

macOS utilizes pixel doubling technology to maintain sharp visuals by rendering at native resolution and scaling UI elements proportionally, though it offers limited built-in scaling options. Windows provides percentage-based scaling with more granular control but can produce inconsistent results across applications and may cause blurry text or graphics in non-optimized apps. Both systems address high-DPI display challenges differently, with macOS focusing on visual consistency and Windows on flexibility, especially for multiple monitors.

Windows vs. macOS Display Scaling

This is now how it works. Through out the years, Windows had a lot of different rendering engines. But, Microsoft is not so bad as Apple that says “Hey! You know that 5 year old machine you paid 10x more? Throw it in a trash, we don’t support it anymore”. Windows still supports rendering text in GDI 32 (Windows 95), WPF (2006), DirectText and WinUI (current). So, yes, there is no way an app written in 1995 to know anything about monitors having more than 800x600px with 96 DPI.
Now, try to run a Mac app from 1995 in your macintosh =P
