AMD 3500u HDMI external monitor not working

Hi, I recently bought an AMD Laptop with AMD Ryzen 5 3500U, the Lenovo ideapad S340-14API. The laptop display broke, so I need to connect the laptop via HDMI, the problem is always I connect throught HDMI with the AMD Vega 8 Driver installed it displays a blank screen.

Curiously with the Microsoft Basic Display Driver the HDMI display works but without sound, bad performance and high temperature, inmediately I install the last driver provided by AMD, or the AMD driver provided by Windows the external HDMI display goes black. Remember, the laptop display is broken.

Is there any solution?

- Windows 10 2004 (May 2020 Update)

- Latest Laptop Bios provided by Lenovo

- Adrenalin 2020 Edition 20.5.1

Thank you

Hello,

same probleme here, on a dell inspiron 14 5000 (Ryzen3500u, vega8), windows 10 pro 64 2004, latest bios and AMD drivers N°20.4.2
The main display works, the secondary HDMI display isn't detected. (it works connected on other PC)

If you have any clues...

Thanks !

Problem solved installing the new graphic driver and AMD chipset driver provided by DELL, which came out mid July...
