So I had been using dex with screen turn off on tablet while connecting with monitor on one UI 7 but after updating 8 and later on, the feature seems disappeared and complicated. I managed to solve by following Reddit post but now couldn't find it anywhere. And it was collided with mouse and keyboard usable features too (it always wake up the tablet and the pointer is not on the monitor).
Is there any possible way to turn off the screen off my tablet while connecting with monitor and mouse/keyboard is only on tablet, not on monitor.
Thank you for the help and sorry that I can't speak Czech.

Dear @Phyo92
Unfortunately, you are right. After the update on the One 8, DeX mode, especially on tablets, was significantly downgraded and became unusable for a large group of users. The only way I find was in this topic at Redit:
Dá se vypnout displej tabletu, když používáš Dex na externím monitoru? : r/SamsungDex
If you are using original Samsung keyboard you can press DeX key and tablet will switch to normal mode, and external monitor will stay in DeX mode. Then you can turn of the tablet screen with button and monitor should stay active.
