Client hardware for surveillance station

I started using surveillance station based off the recommendations here. The couple I deployed thus far just watch the feed on a computer or phone when desired. However, I have a guy that keeps his cameras always on a TV. What super bare essential hardware are you guys using just to show 4 cameras on a TV?

I’m upgrading this guy from bluecherry that I bought 12 years ago and the current mini itx AMD embedded quad core is using Ubuntu to open the bluecherry client. I noticed surveillance station doesn’t have a native Linux client so I might be force to do a windows machine or I guess the other option would be android.

I use wine on my debian 12 install. Sometimes it is difficult! The mouse cursor is never dead on! But I does do anything I need.
I have a sony tv, Android. Using Tinycam Pro. I have 7 cameras on 65" tv. I have it set up to show 4 displays at a time.

It’s not cheap, but Synology does have their VisualStation:
