That might explain the problem. Assuming adguard returns an nxdomain for blocked sites then the devices will try with their secondary DNS server and get to the blocked site

Sorry I misread your post. You shouldn’t need the 172 address in your DNS config, stick to the 127 address only.

In regard to the issue itself. Do your devices show their DNS server as the adguard server?

Your adguard config looks strange. The examples shown list different DNS providers but you have pointed it back at itself for its DNS. I don’t understand why you would do that.

I use Arch because it makes installing almost any software package trivially easy via the AUR and if you run into issues, the wiki is there to help.

You should try out KDE in a Live CD. The snapping and tiling features work very well, Windows needs to catch up

My method to get around this is setting up a specific user account for my TV. In the user options you can disable transcoding

It is paid for, with your time ;)

Jellyfin? It’s always supported 4K afaik

I came to Arch for the customisation, I stayed for the AUR

It sounds like this software was made to address a problem that exists in Windows, poor window management options. Although with Win11 it’s been significantly improved.

Have a look into tiling window managers, or tiling add-ons for major desktop environments. You can split windows in all different arrangements without any extra software or splitting inputs.

Personally I’m using KDE and it’s built in tiling options work very well.

I’m not very familiar with that software, what features does it have that you want to use?

I like VueTorrent

Transcoding 4K isn’t as hard as you think. I used an i5-9500T and the iGPU could easily transcode ~80GB 4K Blu-ray rips at double real time speed. I’ve now switched to software transcoding on a 5800x and it also exceeds real time speed.

There are quite a lot of h265 HDR rips available now, particularly for newer series released on Netflix etc. They definitely support full 10bit HDR and look good to my eyes.
