Control one display or the whole group
Display Control is available on macOS 15 and later and appears in the panel by default. Click a display to add or remove it from the brightness group; at least one controllable display stays selected. Use the top slider for the group, or the slider below a display for that screen alone. If you hid the card, turn it back on in Settings → Panel. Its brightness engine builds on the open-source Crisp project, with thanks to didriksg and its contributors.

Resolution and refresh rate
On macOS 15+, expand a display to choose resolution, existing HiDPI modes and refresh rate. Drag to preview resolution; release to apply. Keep the new mode within 15 seconds or Tutti restores the original; you can also restore manually. While confirmation or recovery is pending, mode and main-display controls are locked. Set as Main Display takes effect immediately. These controls are free and local only, without presets, Remote, shortcuts or automation.
Make your screen brighter in strong light
Pro Outdoors or beside a bright window, maximum brightness may still be hard to read. Brightness Upscaling uses available headroom on eligible displays to brighten the image. In Tutti 1.11.0 on macOS 15 or later, click the sun button beside a compatible display in the Displays card, then drag that display’s own brightness slider above 100%. Pro or an active trial is required. Each screen keeps its own enablement and level. 100% is Neutral; Extra Dim and Upscaling cannot be active together.

Compatible displays
Pro Tutti 1.11.0 retains the existing XDR compatibility list and also checks eligible built-in and external HDR displays for available EDR headroom. Testing includes visible gain on MacBook Neo and an R5 connected through a working Hub, plus XDR Gamma and Metal feedback. This does not certify every display, adapter or lifecycle scenario. Connections can change availability; no fixed physical brightness multiplier is promised.
Built-in model identifiers: MacBookPro18,1–18,4; Mac14,5/6/9/10; Mac15,3/6/7/8/9/10/11; Mac16,1/5/6/7/8; Mac17,2/6/7/8/9.
Recognized external displays: Pro Display XDR; Studio Display XDR (Apple 0x0610: 0xAE21, 0xAE22, 0xAE23, 0xAE2D, 0xAE2E, 0xAE2F, 0xAE42, 0xAE43).
Choose Gamma or Metal
Pro Settings → Control → Advanced Display Settings chooses Gamma or Metal for compatible XDR displays only. Other eligible built-in displays automatically use Metal; eligible external displays use Gamma and may need HDR enabled. The XDR choice does not change those routes. Waiting for EDR is not HDR-content detection.
Save an Upscaling scene in a preset
Pro Save a preset with the display selected to remember its Upscaling switch and level, including enabled at 100% Neutral. Applying it restores the scene; a disconnected display keeps the scene until it reconnects. A newer display command takes precedence. Group brightness, brightness keys, direct brightness shortcuts, Remote, automation, Brightness Following and scrolling stay within 100%; only the display’s own slider or an explicitly saved preset restores the Upscaling range.
HDR, color and turning it off
Pro Upscaling can change HDR content and color accuracy. Tutti does not detect HDR content or turn Upscaling off automatically. For color-critical work, turn it off with the display’s sun button; returning the slider to 100% also restores Neutral. Turning Upscaling off or quitting Tutti removes its image adjustment.
Let external displays follow the built-in display
Expand the built-in display and turn on Follow Built-in Display. Selected external displays then move by the same amount, keeping the brightness difference you set between them. This also lets them follow ambient-light changes when automatic brightness is enabled in macOS.
Use brightness keys, shortcuts & scrolling
After Accessibility access is granted, the keyboard brightness keys control the displays selected in Tutti and show Tutti's progress HUD. Hover the group or one display and scroll to adjust that target; Shift+Option gives a finer key step. Custom brightness shortcuts are available with Pro under Settings → Shortcuts. If Tutti cannot safely take over a key press, macOS keeps handling it.
Save displays in presets and control them from iPhone
Pro Presets save the selected displays and each brightness, then restore available displays when applied; a disconnected display rejoins when it returns. Tutti Remote 1.1.0 adds a Displays page for selecting displays and changing individual or group brightness from iPhone. Both require Tutti Pro, and Display Control must be enabled on the Mac.
