If this helps, its most likely nothing to do with your setup, I'm at my wits end w Samsung, I was able to connect my pc until recently, now the tv a 7000 55" will show connecting, then drops. Not sure what Samsungs playing at, but I will say this, it's annoying and time consuming at best, trying to figure out what the latest update screwed up. Best part, for me have been the last two scheduled updates for my A7 tablets, Back in November give or take- after the update my Wyze app stopped landscaping, no help w online forums. I figured out by zooming 100% (that's under display) I could landscape. Contacted Sam and Wyze, they just talk in circles and say nothing. This last update Dec (talking 2022 for both) I allowed the update on 3 of my A7's Now Blink goes haywire trying to connect, oh I'll get a pict, eventually, but cant landscape or it goes ape -*****, I'm ignoring the updates on my other tablets, but it won't be long before they make it mandatory. Again, I contacted Blink, (this time) then Samsung, once again, no surprise, no answers.
As you guessed, I use the tablets for monitoring Blink, Wyze, and Ring cameras. One tablet per camera, now I can only use the last updated A7's for Wyze since Blink still hasn't resolved the issue and the app goes buggy. I have other Tablets, Lenovo for one, it runs without any Bs and has been for 3 years now, it's actually larger than the A7 Same ***** tablet. Reason for the tablets - there aren't any decent apps that allow connecting multiple cameras to one screen, leastways none I've found. IP View ran well until they went pay me and screwed the app up 6 ways to Sunday, ads etc etc
Note; You can use the Blue stacks app _ runs Android apps and game on PC. its quite handy and you can click on multiple and view more then one item and one time, now that's handy and allows me multiple of the same app, sooo great for viewing security cameras.
Got off topic, don't know what Samsung did to screw up the works pc to tv, I tried pretty much everything - My A7 tablets- still nothing to fix Blink crashing. Not sure they fixed Wyze, but just increase zoom to 100% and Blink wellll.... So I've had my fill of Samsung, when this set goes or maybe before, I'll switch to another brand, with the tablets, replacing them with Lenovo's. In the meantime, ill use Bluestacks.
As far as phone, well that works fine Sam ultra 20. But upgrade time, switching to Apple. Never cared for Apple, not their products, in that they are well above the curve in everything; all in that regard, no I just didn't like the proprietary nature.
Plus I used to jail break and add my own android OS to my phones, custom build, add in some apk's, and a nice OS with no bloated software etc etc
Now it's difficult, but not impossible. Many developers stopped bothering, developing whit OS - pickings are few and far between, and one mistake, and you can brick the phone.
So, sum it up, Samsung updates from what I've experienced do more harm then good, their support, lackluster at best. Not sure why I cant cast to the tv anymore, fast not giving a shi.. about Samsung, I don't recommend their products any longer, I would recommend going LG for a good cost effective tv. Or one of The Majors, Sony etc lot more expensive, but you don't see them popping up with petty BS issues due to a bad install, and you can bet, if that happened, they would be on it like flies on shi.. Oh well I can go around the block and use my phone, which still works, (until the next update maybe) or I could hardwire, wish I had an answer for the pc to tv w/out purchasing additional hardware to cast. I'm not a novice. with all this, but they keep overtaking the plumbing, (txs Scotty) and not plugging the leaks. hell they don't bother mopping up either <Heavy Shrug>
