I have Samsung UE40J5200AW and it has that screen mirroring feature. Whenever I try to use to cast from Windows 11 to this TV, the stream stops after few mins of playing.
I have no idea if Samsung doesnt allow to play full screen videos from casting devices or not. I have tried to connect both PC and TV via Ethernet and see if it will help, but its happening all the time.
Whats interesting it also happens when I cast via my lineage os phone and I checked it on different TV and had the same issue.
Whats your ways to cast videos from PC/laptop to TV?
If I’m on the go, I’ll hook up my laptop to the TV with an HDMI cable, set the TV as a duplicate screen so I can close the lid on my laptop (make sure closing the lid doesn’t lock your computer or put it to sleep), then use my wireless mouse and keyboard so I can sit on the couch/bed/whatever and control it from afar.
At home, I bought a micro PC that I keep connected to the TV via HDMI. Then I use a wireless mouse/keyboard to control it from the couch.
The micro PC has WiFi so I can connect it to the Internet, and all devices on my home network can see each other, so I can quickly copy something from my regular PC or laptop to the micro PC if I want to view it on the TV.
I mostly use the micro PC for my streaming services. I don’t trust my Smart TV to be connected to the Internet, so I don’t use any of its apps. But I’m old; I’m used to TVs being dumb devices. I don’t like handing over control of my apps to companies; I’d rather access them directly from a computer.
