Let’s get the conclusion out of the way: if you need display plumbing, meaning virtual screens, resolution tricks, and EDID surgery, buy BetterDisplay. Nothing else on the Mac does what it does, mine included, and I have no plans to compete with it. The interesting question is narrower: if all you want is brightness that stays matched, which tool fits?
What BetterDisplay does well
Nearly everything, which is precisely its character. Virtual and dummy displays for headless Macs and streaming rigs. HiDPI resolution unlocking for monitors macOS treats poorly. EDID overrides, picture-in-picture, input switching, rotation. It is the deepest display utility on macOS, its free tier is genuinely generous, and $21.99 buys more capability than anything else on this list.
Two specific credits. Its adjustable wake delay taught the whole category that some monitors need seconds of quiet after waking before they’ll accept commands. My own wake timing knob exists because their users proved the need. And its distribution model is the one I adopted: closed source, public repo for releases and issues. When I say the competition shaped this app, BetterDisplay shaped it most.
Where this app differs
BetterDisplay’s brightness sync normalizes displays by their physical nits: clever, principled, and grounded in what panels report about themselves. The catch is in that last clause: it depends on what panels report. A panel that misreports its range, or reports none at all, gives even a correct formula bad numbers to work from.
I went the other way. No spec sheets, no nits: you set each panel by eye twice, once in a dim room, once in a bright room, and each display gets its own line. The master’s travel is computed as the intersection of what your panels can actually do, so a narrow-range display bounds the set honestly instead of silently flattening it. Mixed-range setups are the exact case the design was built around; mine is an ASUS that macOS manages natively next to an LG on raw DDC, which is about as mismatched as desks get.
And scope: BetterDisplay is a toolbox that rewards a settings spelunker. Mine is one slider, a gear, and a single idea: that identical percentages don’t match panels, with a plain-text log so anything the app does can be traced to a cause.
Choose accordingly
- Choose BetterDisplay if you need any of the plumbing: virtual displays, HiDPI, EDID, PIP, input switching, or one app that does brightness and all of that.
- Choose Brightness Controller if brightness is the whole job and you want mixed-range panels matched to your eye, free, from a one-knob menu.
- Running both is reasonable: plumbing from one, matching from the other. Just let one app own brightness, or they’ll argue.
