Windows 10: Extend laptop to multiple tv's and monitors using a repeater.

Trying to extend my HP laptop to multiple tvs and a monitor for karaoke in a bar. I am using a "Gator" 1x4 repeater. when i use the laptop as the input it is not recognized. what am I doing wrong, settings wise, or do I need a different repeater? In Display settings, it is not recognizing the repeater as an additional display. Any help is welcome. Thanks

Extending display to multiple monitors

I have 4 monitors that I would like to connect to my laptop and extend display. I can't seem to find anything that will allow me to do this. My laptop doesn't have a docking station. Any suggestions?

 

Cast to TV not repeatable on new laptop

Yes they are both on the same network. The TV is hard wired but we also disconnected that and connected it wirelessly to try that and that didn't work either. It works if the TV is removed from the list and then added again but is not repeatable either way.

When I first tried casting on the new laptop I added the TV and the permission screen popped up on the TV. I allowed it to connect always and it did connect but is not repeatable unless I remove the Samsung TV from the Bluetooth & devices > Devices screen screen in settings. It appears there under both Audio and Wireless displays & docks. When I remove the listing under Audio, it also deletes the listing under Wireless displays & docks. I can then add it again using all the methods in the article you listed and it WORKS the first time and casts to the TV. However, when I click on the DISCONNECT icon in the tray and they try to cast again, I get connection failed on both the laptop and the TV. If I remove the TV and add it again it works. Very frustrating.

After it's added, something is blocking it from loading again. I did not have this issue with my old Dell laptop running Windows 10 so it's either this new laptop or Windows 11 or something else. The HP tech mentioned McAffee which I turned off and tried it that way but no difference. It wasn't repeatable that way either.

 

Cast to TV not repeatable on new laptop

Brand new HP laptop running Windows 11. When I ADD DEVICE to cast to my Samsung TV, the TV shows up as an available device and the laptop mirrors or casts to the TV. In otherwords, IT WORKS! However, after you disconnect and try to reconnect again it fails to connect. Both the TV and laptop report connection errors. The only way to get it to connect again is to remove the TV from the Bluetooth and Device list then add it again and it works, but just initially again and is not repeatable.

I've spent hours troubleshooting fixes online and none work. Yesterday I was on the phone with HP support for over an hour. They remotely operated my laptop and tried many fixes and none worked. Wireless display is installed and all drivers are up to date including the TV software. They finally suggested reinstalling Windows but I'm not wanting to do that and loose all the "stuff" I've spent four days installing from my previous laptop. BTW my old laptop on Win 10 worked everytime as does my phone and iPad so I'm guessing it's a window 11 issue.

The Wireless Display app is installed and says that it's ready for me to connect but then goes on to say "Protected content can't be viewed on this device" Next it says Press Ctrl + S to open settings. When I do that a window opens up but does not show any Allowed Devices or Blocked Devices on the Device Access List. There are no options to add anything. Not sure if this is the problem.

So the question is, why does cast work when first added but then will not repeat to connect again unless I remove the TV and add it again?
