I have following problem. I have a Dell Inspiron 14 2-in-1 with AMD Ryzen 7 5700U.
After connecting 4 monitors it wrote for all monitors configs means it recognise them.
In Windows I can select them but can't setup a 5 displays.
Does the Radeon Graphics hardware support this or is it impossible?
Go to Solution.
Most likely Vega 8 Graphics doesn't support 4 external displays only 3 external displays.
The Vega 8 graphics is based on the same Vega 8 used in the 4000 series APUs.
According to Wikichips concerning AMD Ryzen 7 4800U using Vega 8 it supports a Maximum of 4 Displays: https://en.wikichip.org/wiki/amd/ryzen_7/4800u#Graphics
So if the above is the same for the 5000 series Vega 8 your laptop will only support 3 external Displays plus the laptop's own display for a total of 4 displays.
