## How to enable
|
|
|
|
To enable Advanced Preferences for monitors, toggle the "Show advanced settings" checkbox at the bottom of the Displays tab.
|
|
|
|
Inside the advanced preferences you can experiment and modify some more advanced settings.
|
|
|
|
### Polling Mode
|
|
|
|
Sets the amount of times MonitorControl will try polling the display.
|
|
Polling the display essentially means that it tries to read information from the display.
|
|
This can sometimes be unreliable and thus MonitorControl will try reading these values multiple times to increase success rates.
|
|
Polling is used for reading current display volume and brightness values, which happens on app launch or when
|
|
coming out of sleep mode.
|
|
Because we try to read the values multiple times (for example, 10 tries for volume and 10 tries for brightness on `Normal` mode), it can cause some slowdown on your system. The different polling modes indicate a different amount of times we try to poll the display for information.
|
|
|
|
#### Polling Modes
|
|
|
|
- None: 0 tries
|
|
- Minimal: 1 try
|
|
- Normal: 5 tries (default)
|
|
- Heavy: 20 tries
|
|
- Custom: X tries (user specified in the "count" field)
|
|
|
|
In case the display is still unable to read the values through DDC (or you selected `None`), the last known values will be used instead.
|
|
|
|
**If you experience significant system slowdown when coming out of sleep mode or at startup, try lowering or disabling the Polling Mode setting.**
|
|
|
|
### Longer Delay during DDC read operations
|
|
|
|
Some displays will require a longer `minReplyDelay` (referred to as `Longer Delay` in settings) to be able to read display information more reliably.
|
|
This depends on a combination of different factors like Cable, Monitor, GPU.
|
|
|
|
If it takes a long time to read your volume and brightness settings, you can try enabling the `Longer Delay` settings to improve reliability. However, please be aware that this setting will not work for every system and **may cause your system to freeze after enabling it. Please use this at your own risk.**
|
|
As a safety measure, automatic app startup will be disabled.
