No connection to Samsung SmartTV UE55ES8090

Plex Media Server

I have the Synology NAS DS720+ with DSM 7.2.2
When I open the PLEX Android app on my TV, I get the following information
“Connect to Plex; Open the browser on your PC”. Next to it are 4 empty fields to enter a 4-digit code. However, the page is unusable.
My real account name (not connected) is displayed on the TV.

Then I opened the browser on my PC.
Nothing is displayed.
Hence the first question:
What should happen when I open the PC?

I am logged into the correct account both on my PC (the Plex page was accessed via my NAS) and in my Android app.
If I now enter the URL https://www.plex.tv/link/ in my browser, I see the image Plex Link Account, To link your account please enter the 4-character code displayed on your app.
Hence the second question:
Which app is meant? A 4-character code does not appear on the interface of my PC, nor in the browser, nor in the Android app.

The following appears under “Approved devices":
Chrome (Plex Web), my smartphone and my NAS appear under “Authorized devices”.
My TV is not visible.

I believe your Samsung TV (2012 Model) is too old and the Plex app is no longer supported on that TV.

Your best options would be to use a Fire TV, Roku, Apple TV or any similar device connected to your TV.

All of the devices mentioned, have current Plex apps available.

My personal recommendation would be a Fire TV 4K or 4K Max stick. They are quite affordable and work well.

You can also purchase a new TV, but I am guessing you would rather not do that.

Thanks for the quick reply.
I have a Chromecast Ultra with Ethernet connection on the TV.
Can it be used for this and if so, how?

Yes, you can setup Plex on the Chromecast.

This article should be able to help you with that:

Here are some articles from Plex that should help also:

Grab the Plex player from Orca. It supports the old Samsungs TV, and it works really quite well.
I think 2.14 is the best working version.

Should be available here, unless Plex in its wisdom have removed them.
(Plex_2.014_11112020.zip)is the archive name, but search for “Plex for Samsung orca” or something
It should even be available on Samsung Smart Tv.
