# HDRTray

Windows Notification Area icon to show and change HDR status. Useful if you quickly want to check the current setting, maybe because it might been changed automatically by some applications, or maybe just because you're forgetful. Also allows quick toggling.

## Usage

After starting the program you can see a new notification area icon, displaying either “SDR” or “HDR” depending on whether HDR is off or on.

HDR can be toggled on or off with a left-click on the icon.

Right-clicking opens the context menu offering an option to automatically start the program when you log in to Windows.

## Command line utility

Since version 0.5, the `HDRCmd` command line utility is included. It can be used to toggle HDR on and off from scripts and check it's status.

Syntax:

    HDRCmd [SUBCOMMAND] [SUBCOMMAND-OPTIONS]

## `on` command

Turns HDR on on all supported displays.

Does not accept any options.

## `off` command

Turns HDR off on all supported displays.

Does not accept any options.

## `status` command

Prints the current HDR status to the console. Has a special mode that returns an exit code depending on the status.

### `--mode` (`-m`) option

- `long`, `l`: Print the overall HDR status and status per display.
