In DEX mode, how to run portrait apps in full screen? Or display PDF in portrait orientation.

[CyberSSS]

Samsung DeX is a highly productive mode. However, why is there still no portrait mode for DeX?

Using these flagship smartphones with a portable screen is very convenient.

BUT

• DeX cannot properly display A4 PDF files in portrait orientation because it only supports landscape mode😞. I need to show music sheets!
• DeX cannot play vertical games in full screen because it doesn’t support portrait mode😞.  I want to have a full portrait screen game experience!

Why not add a landscape/portrait switch button for DeX mode?

Enabling portrait mode would greatly enhance productivity and usability in DeX mode.

Please, currently is there any workaround to rotate apps in DeX?

And Samsung development team, please enhance DeX to support both landscape and portrait modes in future updates.

PS: My device is S23 Ultra, using usb c connects to a 14 inch FHD portable screen.

Thanks!
