With 100 percent scaling - that is, a 1:1 pixel ratio - the Windows desktop and user interface appears tiny, and is likely too small for most users. In our example, we’re using a 27-inch 4K monitor with a native resolution of 3840×2160.

Here’s a quick look at display scaling in Windows 10.įirst, let’s look at an example of why display scaling is needed in most cases when using a high resolution display with a Windows 10 PC. The answer, therefore, is to make the user interface relatively large enough to be useable while still taking advantage of the millions of extra pixels available on high resolution monitors - something called display scaling in Windows (you may also recognize this basic idea from what Apple calls “Retina” resolutions). This worked well for resolutions up to 2560×1600 on an adequately large monitor, but once you get into the 4K resolutions of today’s high-end monitors, a 1:1 pixel ratio - or 100 percent scaling, as Windows refers to it - produces an image that is unusable in most circumstances. For years, traditional “standard resolution” displays were typically handled by Windows in a 1:1 ratio, with your PC’s video card providing one pixel of the actual user interface for every physical pixel on the display. Now that high resolution displays are more affordable and prevalent than ever, it’s important to understand how to configure Windows to ensure the best experience at 4K resolutions and beyond.
