Ideas and bug reports

Email contact@gramshift.com in English or Japanese. Ideas for new features and bug reports are welcome, and every message is read; we do not guarantee a reply time. Please include your Windows version (Settings > System > About), your Stream Deck app version, your monitor models, and a screenshot of the key's settings page (its Status line says what the plugin sees).

Get started

1. Turn on DDC/CI in the menu of each monitor (often under Setup, System or Others). Many monitors have it on already.
2. In the Stream Deck app, find Monitor Brightness for Windows in the action list and drag Brightness onto a key. The key shows the brightness of the monitor, for example MON 1 80%.
3. In its settings, choose the Monitor (or All monitors) and what a press does: set a value, step up or down, or switch between two values.
4. For the schedule, drag Auto onto a key, choose At set times or At sunrise and sunset (pick your city), set the day and night values, and press the key.

The actions

• Brightness (key): one monitor or all of them. Press: set a value, step up or down, or switch between two values. Change: brightness or contrast. Hold for 1 second to go to your base value.
• Brightness Dial (Stream Deck +): turn to change brightness or contrast by the step per notch; fast turns are sent as one change. Push to switch between automatic and manual. Touch the screen to go to your base value.
• Auto (key): starts and stops the schedule. The key shows the brightness now and the next change, such as 18:42 → 30%.
• Warmth (key and dial): makes the screen colors warmer (less blue), from 6500K (off) down to 2700K.
• Scene (key): brightness, contrast and warmth for every monitor in one press. Take the values now saves what each monitor shows, so the scene sets each one to its own value.
• Look (every key): Classic, Ring, Solid or Sky. Sky shows a day, sunset or night sky by the time of day.

The schedule

• At set times: day starts and night starts at the times you choose, by the clock of your PC. 07:00 stays 07:00 when daylight saving time begins or ends.
• At sunrise and sunset: worked out on your PC for the city you choose (220+ cities) or for coordinates you type, with an offset of up to 2 hours each way. On a day with no sunrise or no sunset (near the poles), the set times are used and the key says so.
• Day and night each have a brightness and a warmth. The change is gradual over the time you set (0 to 120 minutes).
• A change by hand (any key, dial or scene) holds the schedule until its next change; the Auto key shows MANUAL until 18:42. At that time the schedule runs again. Press the Auto key to go back immediately. Pressing the Auto key while the schedule runs switches it off and gives the displays their own colors back.
• The schedule writes when it starts, while a change is in progress (about once a second during a fade), and when a manual hold ends. Once a change has finished, it writes nothing until the next change, so a change made with the monitor's own buttons stays until then.

After sleep and when a monitor is plugged in again

When the PC wakes up from sleep, the plugin writes each monitor's value again a few seconds later (and once more for a monitor that did not answer yet). A monitor that is plugged in again, or switched back on, gets its value back too. The value is the one the schedule wants when it runs, otherwise the last value you chose with the plugin. The colors are written again as well. Nothing is written back at any other time.

All monitors and monitor names

In the settings of a Brightness key or dial, the Monitors list shows each monitor with a Name (shown on the keys), a Lowest and a Highest value, and Identify, which changes that monitor's brightness for a moment and back, so you can tell which one it is. With All monitors, 0% sets every monitor to its lowest value and 100% to its highest. A monitor that does not answer DDC/CI is left out.

Warmth and your colors

• Warmth changes the color table (gamma ramp) that Windows sends to each display. It works on every display and does not need DDC/CI.
• Before the first change, the plugin keeps a copy of each display's own color table. The original comes back when you switch warmth off, stop Auto, or close Stream Deck. Removing the Warmth or Auto key from its page gives it back too, but only while another key of this plugin stays on that page (the Stream Deck app does not tell a plugin that a key was deleted). If the plugin stops unexpectedly, a small helper gives the colors back, and the next start checks again. A color table is written back only to the display that showed the same monitor when it was read: if the displays were renumbered meanwhile (for example after unplugging), it is not written.
• Windows limits how warm a display can get. When Windows refuses a warmth, the plugin uses the warmest one Windows allows and the key says limited.
• While HDR is on, Windows may refuse the change. Then the key says Not available and nothing is changed. The plugin tries again a few times (after 15 seconds, then less often), and once more when you press the key, change a setting, the PC wakes up or a display comes back.
• Windows Night light also warms the screen. If both are on, the screen is warmed twice.

Troubleshooting

Compatibility

Tested on Windows 11. Windows 10 is supported by the Stream Deck app but has not been checked by us.
