    ## Updates regarding macOS 14 Sonoma Beta

    **USB-C to DisplayPort**<br/>
    The macOS 14 Sonoma seems to outputs RGB color by default when using USB-C to DisplayPort cable.

    **HDMI to HDMI**<br/>
    The macOS 14 Sonoma seems to outputs YCbCr color by default when using HDMI to HDMI cable.

    - Forcing RGB Color Output still seems to work with the [original procedure](https://gist.github.com/GetVladimir/c89a26df1806001543bef4c8d90cc2f8#the-step-by-step-procedure-on-how-to-force-rgb-color-output-on-m1-and-m2-based-macs-with-terminal-commands) of modifying the plist files

    - Modifying the display plist files still works with the [alternative version](https://gist.github.com/GetVladimir/c89a26df1806001543bef4c8d90cc2f8#alternative-terminal-commands-to-force-rgb-color-output-on-m1-and-m2-based-macs-and-workaround-for-losing-rgb-color-after-waking-up-from-sleep)

    - After the plist files are modified, putting the Mac to sleep and waking it, it seem to keep the RGB Color output (this seems to be fixed at least on a M1 Mac mini)

    ## Updates regarding macOS Monterey

    **USB-C to DisplayPort**
    From what I've seen, it seems that macOS Monterey 12.0.1 finally outputs RGB color by default on some monitors when using USB-C to DisplayPort cable on M1 Apple Silicone Macs.

    You might need to make a backup and delete these 2 files:
    `/Library/Preferences/com.apple.windowserver.displays.plist`
    and
    `/Users/yourname/Library/Preferences/ByHost/com.apple.windowserver.displays.[UDID].plist`

    Restart your Mac and it should properly output RGB color on the monitor on the next boot.
    <br/><br/>
    **HDMI to HDMI**
    The situation with HDMI seems to got a bit more complicated. Now the whole section for the LinkDescription might be missing from the com.apple.windowserver.displays.plist on a clean install and doesn't seem to be recreated when rotating the screen either.

    Luckily, [the solution still works](https://www.youtube.com/watch?v=Z1EqH3fd0V4), but you might need to manually add this whole section in the displays plist file:

    ```
    <key>LinkDescription</key>
    <dict>
    <key>BitDepth</key>
    <integer>8</integer>
    <key>EOTF</key>
    <integer>0</integer>
    <key>PixelEncoding</key>
    <integer>0</integer>
    <key>Range</key>
    <integer>1</integer>
    </dict>
    ```

    The section usually goes right under the **CurrentInfo** key, and it should look something like this:

    ![pixelencoding](https://user-images.githubusercontent.com/84543265/139309531-636095e1-ca75-478d-b1cd-0a3680107149.png)

    This should get your RGB color output working on M1 Mac mini, even when connected with HDMI to HDMI cable.
    <br/><br/>
    **Multiple monitors when one them is using HDMI to HDMI**
    Additional thanks goes to @somogyi-ede who tested this with multiple monitors and confirmed that the LinkDescription key needs to be added under each monitor instance in order for all of them to receive RGB color output.

    ## Background

    While doing a lot of testing on how the Dual-Cable workaround makes RGB to work on M1, I've discovered what changes it makes to macOS, and managed to create a more streamlined workaround **without the need to use a second cable.**


    To make things easier, I've created a step-by-step video tutorial of the whole procedure that should force RGB color output on your M1 Mac connected to an external monitor, and works on an HDMI-to-HDMI cable connection.
