Displaperture is a macOS menu-bar utility from Many Tricks that applies software-rendered rounded corners to one or all of your displays, softening the hard rectangular edges of any external monitor to match the aesthetic of a modern Mac screen.
What is Displaperture?
Displaperture is a tiny, single-purpose app that masks the corners of your display with smooth, adjustable curves. Apple's built-in displays have shipped with rounded corners for years, but plug in a Dell, LG, or Samsung external monitor and you're suddenly staring at four sharp 90-degree angles. Displaperture fixes that inconsistency with a preference pane and a live preview — no hardware modification required.
The app draws a transparent overlay at the very top of the window stack, so the rounded mask follows you across spaces, full-screen apps, and everything in between. The radius is adjustable, letting you dial in anything from a subtle softening to dramatically pillowed corners, depending on how aggressive you want the effect.
What does Displaperture do best?
The strongest thing Displaperture does is stay completely out of your way. There is no dock icon cluttering your launcher, no notification badges, no update nag screens — just a lean menu-bar presence and a settings window you open once, tweak, and forget. After fifteen minutes with it running, the rounded corners feel native rather than painted on.
Where I appreciate it most is in multi-monitor setups. My MacBook's built-in display sits alongside a pair of external monitors, and without Displaperture the mismatch in corner treatment is immediately noticeable. Applying a matching radius to the externals creates visual parity that a designer's brain will appreciate on a subconscious level, even if you can't articulate why the desktop suddenly feels more cohesive.
- Per-display control: apply different radii to different screens, or lock them to a uniform value across the whole setup.
- Live radius preview: the slider updates the mask in real time so you never commit to a value blind.
- Login item support: launches silently at startup and re-applies your settings before your first coffee.
- Full-screen and Spaces aware: the overlay persists correctly when you switch spaces or enter full-screen mode.
How much does Displaperture cost?
Displaperture is available directly from Many Tricks at a low one-time price — no subscription, no in-app purchases, no seat limits. Many Tricks also bundles it with their broader suite of Mac utilities if you're already a customer of apps like Moom, Witch, or Desktop Curtain. A free trial is available from the developer's website so you can confirm the corner rendering looks right on your specific display before committing.
Who should use Displaperture?
The obvious audience is anyone who pairs a MacBook or Mac mini with external displays and finds the squared-off corners jarring against the elegant curves of macOS. Designers and video editors who spend long hours staring at their screens tend to feel this mismatch most acutely, but it bothers plenty of developers and writers too once they notice it.
Beyond aesthetics, Displaperture is genuinely useful for anyone producing screenshots or screen recordings for marketing or documentation purposes. Rounded display corners give your screen captures an immediately polished, contemporary look without post-processing in Figma or Pixelmator. If you regularly share screenshots on social media or in a Notion doc, the difference is visible.
It is not the right tool if you're looking for something that also handles display colour profiles, brightness scheduling, or resolution switching — apps like MonitorControl, Lunar, or BetterDisplay cover that territory. Displaperture does exactly one thing and does it cleanly.
What are the best Displaperture alternatives?
The most direct comparison is Lungo-era corner utilities, but nothing else is quite this focused. BetterDisplay has a corner-rounding feature buried inside a much larger feature set — if you already use BetterDisplay for resolution scaling or HDR tone-mapping on your external, you may not need Displaperture separately. rcmd, PopClip, and other Many Tricks stablemates complement rather than replace it.
If you're on Apple Silicon and only use Apple displays, the operating system already handles corner rounding natively and you don't need this app at all. Displaperture is specifically for the gap between what macOS renders natively and what third-party displays provide.
How does Displaperture compare to BetterDisplay's corner feature?
BetterDisplay's rounding is tied to its virtual screen and display-override stack, which means it can misbehave or require more setup when used with certain GPU/display combos. Displaperture's overlay approach is simpler, more predictable, and starts working the moment you move the slider. If your only goal is corner rounding, Displaperture is more reliable and costs less. If you need BetterDisplay's other display-engineering features, it's a reasonable consolidation to just use that instead.
