ArrayLux changes brightness and contrast inside the monitor itself — no bezel buttons, no grey overlay. And when 0% is still too bright, it keeps going.
Sound familiar?
In a menu nobody designed to be used. Then the same thing on the second monitor. And tomorrow again.
At 1 a.m. the lowest setting still lights up the room — the backlight simply will not go further.
So you adjust by hand every time you switch — or you give up and live with the wrong picture.
ArrayLux takes all three off your hands.
Control
Global shortcuts keep working in fullscreen, with an on-screen readout so you see what changed.
Brightness, contrast, Sub-Zero, night light and saturation — even inside fullscreen games.
One flick of the mouse wheel sets every screen at once.
One slider moves all of them and keeps the offsets between them.
Automation
Dimmer for video editing, brighter for spreadsheets, punchier for games. ArrayLux follows the window in front — Alt+Tab away and the previous profile comes back.
ArrayLux works out sunrise and sunset for your city and eases brightness along with the day. Prefer to decide yourself? Build a schedule with as many time points as you like.
Why it looks better
Most dimming tools lay a dark layer over the picture. ArrayLux talks to the monitor over DDC/CI — the same channel its own buttons use — so the backlight itself goes down.
Contrast survives because the panel is not fighting an overlay.
Lower backlight means less glare in a dark room — not just a darker image.
A dimmer backlight uses less energy than a bright one hidden under a filter.
Sub-Zero dimming
Most monitors stop dimming long before the room is dark. Sub-Zero picks up exactly where the backlight gives up.
Works in software on top of the hardware — so it also runs on laptop screens and monitors without DDC/CI.

FAQ
Hardware brightness and contrast need DDC/CI, which most monitors from recent years support — it sometimes has to be switched on in the monitor’s own menu. Sub-Zero, the blue light filter and saturation work in software, so they also run on monitors without DDC/CI and on laptop screens.
ArrayLux sends the standard DDC/CI commands the monitor is built to receive — the same kind of signal its own buttons produce — and stays within the range the monitor reports. It does not flash firmware or change anything permanent.
The Windows slider is made mainly for built-in laptop displays; for most external monitors it does nothing. It also cannot go below the monitor minimum, switch per app or follow the sun.
Nothing you have to do. ArrayLux keeps running as the free version with no time limit. If you want the automatic features back, you can buy Pro once inside the app.
Yes. Per-app profiles switch when a game comes to the front and switch back when you leave it, and the global hotkeys work inside fullscreen games.
As many as you have. Each one gets its own card, and you can link them so one slider moves all of them while keeping the offsets.
ArrayLux lives quietly in the notification area. Hardware commands run on background threads, so neither the interface nor your games wait on a monitor.
