Here I will provide some suggestions and try to explain why I recommend these settings. Adjust it to your own liking and keep in mind that it is only a suggestion. I'm not a Plex Pro in anyway :bangbang:
I will only cover settings that I think might be interesting or are personal preference, if you would like me to cover some other settings, please contact me on [](https://trash-guides.info/discord){:target="_blank" rel="noopener noreferrer"}
1. Manually specify public port if you run Docker or want a fixed port.
1. Enter the Plex port you want to use. (default: `32400`)
1. Click on `Apply` and when everything is setup correctly, your Plex Media Server should be fully accessible outside of your network, so you can connect to your Plex server from outside. You may also need to configure port forwarding on your router. Detailed instructions are available [HERE](https://support.plex.tv/articles/200931138-troubleshooting-remote-access/){:target="_blank" rel="noopener noreferrer"}.
When a change is detected in the source location for a library’s content, the appropriate library will be scanned. This function relies on the computer’s operating system providing the “something changed” trigger. Some operating systems don’t provide this trigger and content mounted via a network will also typically not work. If your library doesn’t automatically scan, you may have to set a periodical scan or do it manually.
If for some reason ex. your operating systems don’t provide this trigger or your storage is mounted on a network (SMB/NFS/Cloud Storage) or your library just doesn't automatically scan, or is just plain impractical, You might want to consider using autoscan. IBRACORP (A Youtube channel I collaborate with) has a video explaining it in further detail.
Please don't forget to check out his other Unraid Video's [HERE](https://www.youtube.com/c/IBRACORP/videos){:target="_blank" rel="noopener noreferrer"}
When changes to library folders are detected, only scan the folder which changed rather than scanning the entire content location. This works together with the normal Update my library automatically setting (and requires that setting to be enabled).
With this option enabled, when an item’s file is deleted from the drive, it will be removed from the Plex library on the next scan. Disabling this option keeps the item in the library with an overlay over the item’s poster when the item is removed.
*In my opinion Plex shouldn't touch your media files. Use Sonarr/Radarr to manage your media library. (For extra security I've setup Plex with Read Only access to the media library)*
#### Run scanner tasks at a lower priority
On low-powered systems (e.g. ARM-based NAS devices), it can be beneficial to run scanner tasks at a lower priority than other tasks. This can help ensure they do not interfere with regular streaming.
*Makes sure it uses less resources and ensure they do not interfere with regular streaming.*
#### Generate video preview thumbnails
This option creates a series of preview thumbnails from a media item when it is analyzed. These images are used by some Plex apps when you move back and forward in an app with the timeline scrubber. They’ll also be displayed in Now Playing when someone is streaming from you so that you can see where they are in the video.
The images are stored in your Plex database location (/config) so <u>be careful you don’t fill the drive :bangbang:</u>
#### Generate intro video markers
You can choose to have TV episodes analyzed to try and detect when the “intro” occurs during playback. When detected, apps will then offer a `Skip Intro` button, allowing you to quickly jump over the intro.
Chapter thumbnails provide images in the chapter view on supported apps. They can take a little time to generate and consume very minor additional disk space.
*Accept and prefer secure connections when they’re available for a Plex app, but allow regular HTTP connections if the app doesn’t support secure connections or if one can’t be established*
For users with multiple network cards or systems such as NAS or Docker where there is always another network interface which Plex client applications may try to use to connect to the Plex Media Server, with this option you can ensure that your local Plex clients would only try that interface.
If you have enabled Remote Access enabled and are having Plex automatically map the port (as opposed to specifying a port manually), then Plex Media Server has no control over which network interface is used for an automatically-mapped port. Thus, it’s possible that Remote Access connections could come through an interface other than the one specified here.
If this setting is enabled, it prevents Plex Media Server from using or accepting the deprecated TLSv1.0 and v1.1 protocols, as well as legacy weak ciphers. May prevent older clients from connecting. The vast majority of users will have no reason to enable this option (and receive no benefit from doing so).
Allows incoming requests from this network’s WAN IP address to be treated as LAN requests in terms of bandwidth. This often occurs when DNS rebinding protection is in place and clients on the LAN cannot contact the server directly but instead have to go through the WAN IP address.
A comma-separated list of URLs (either HTTP or HTTPS), which will be published to plex.tv for server discovery. This can be very useful in a few cases: if you’re using a reverse proxy in front of the media server, or if your networking configuration is otherwise unique. For instance, if you have your own custom domain with subdomain.
This feature can be enabled to allow your server to send events to external services. For example [Notifiarr](/Notifiarr/Quick-Start/){:target="_blank" rel="noopener noreferrer"}
This feature allows Plex Media Server to maintain high visual fidelity of content, by applying tone mapping to convert it to SDR when transcoding HDR content.
*Most HDR content will be in 4K resolution. If your platform has to use software transcoding to perform the tone mapping, then it may well struggle convert 4K content in real-time, unless you’re running on a very powerful system.*
Plex’s tone mapping support should generally be able to produce good color mapping and help avoid the “washed out” colors that occur when converting HDR content without tone mapping.
*Besides being much faster at scanning and getting metadata, one of the benefits of the new agent is that all agent settings are set at the library level, so that different libraries using the same agent can have different agent settings.*
1. This option creates a series of preview thumbnails from a media item when it is analyzed. These images are used by some Plex apps when you move back and forward in an app with the timeline scrubber. They’ll also be displayed in Now Playing when someone is streaming from you so that you can see where they are in the video.
Creating these images can <u>take a considerable amount of time</u>, <u>CPU resources</u>, and <u>increase the storage space used</u>. The images are stored in your Plex database so <u>be careful you don’t fill the drive :bangbang:</u>

*Ever watch a TV show and it starts playing that same minute and a half credits intro that you've already watched multiple times? Well, you can have your Plex Media Server analyze the TV shows to try and detect those introductions and then let you skip through them with a single click!*
