I am using a USBC(DP) to VGA adaptor.
I have plugged in a USBc(DP) to VGA adaptor into the unit. I now have 2 screens (HDMI and VGA) cloned.
Now when I go into Android Settings / DP / Resolution - I do not get a complete list of resolutions available?
It simply shows 2 options Auto and 1920x1080p60.00
The unit should show all resolutions that the adaptor can handle.
I have also tried Leungs dts patch, but still no luck?
I want to use the adaptor with VGA at 1280x1024?
What other files do i need to change. DTS has patych below
/dts-v1/;
#include “rk3399-firefly-aioc.dtsi”
/ {
model = “Firefly-RK3399 Board BOX (Android)”;
compatible = “rockchip,rk3399-firefly-aioc”, “rockchip,rk3399”;
};
&hdmi_dp_sound {
status = “okay”;
};
&route_hdmi {
status = “okay”;
logo,mode = “center”;
};
&hdmi_in_vopb {
status = “okay”;
};
&hdmi_in_vopl {
status = “disabled”;
};
&dp_in_vopb {
status = “okay”;
};
&dp_in_vopl {
status = “okay”;
};
