S24 Ultra USBC to USBC video no longer working.

[FatherOfMayhem3]

After the latest update the usbc to usbc video no longer works. I can connect my external monitor like I always have but the display never turns on. The display and cable work fine with other devices just not my Samsung s24U.

Any other people experiencing the same thing?

USBC to HDMI works fine. But that means another power cable needed.

Did you try wiping phone cache?

Will give it a try

I'm having the same problem, did you find a solution?

After about 20 seconds of being plugged in I can open DEX and it works. BUT the screen now needs external power to run

The display needs power which is complete nonsense because the S23 or below doesn't need power so why did they change this is beyond me.  Samsung needs to fix this dumb issue as the whole point of having an external display option is to make it mobile.

Another one with same problem. I am using arzopo s1 table. IT works with all other devices even usbC to usbc, with samsung, nothing.

Same issue. 

I have an Arzopa monitor. If I plug my old Note 10+, DeX launches immediately. 

With the S24 Ultra I get a No Signal video.

Same cable.

It works fine using a Usb-c hub with HDMI output, but I need to use the hub + external power.

Samsung should fix this since it's probably a software issue.

Same here on S24 plus user. I dont have the mini HDMI cable at the moment, so it won't work as it used
