I tired using usb c connection and wireless and it connects, then disconnects. I tried with Wi-Fi off, turning off the firewall, disabling the GPU and nothing works. It worked great a couple weeks ago, only thing that has changes is there was a Samsung update, a windows update, and I upgraded my Nvidia 4060 to a 9070 XT. But it will not even connect to my rog ally X. which is what I used it for primarily, same windows update also. Can anyone help?</SPAN></P> Thu, 02 Apr 2026 13:24:56 GMT MichaelZech 2026-04-02T13:24:56Z https://us.community.samsung.com/t5/Tablets/Second-Screen-app-stopped-working-S11-Ultra/m-p/3520930#M50386 <P><SPAN>My second screen is not working on my S11 Ultra.
