2nd Screen Control and OBDII

grendizer

Hello,
I have the DUDU7 and have a few questions regarding the 2nd screen and OBDII:

I currently have a second screen connected to the DUDU7 on the USB-C port via an HDMI to USBC adapter. The 2nd screen is showing the app menu, and I can't do anything else with it (it's a non-touch display). Looking through the settings, I was only able to change the screen to mirror mode as well as change the margins (in the Android settings). I want to be able to display a certain app(s) on that second screen (something like google maps, while the main display has other apps displayed), is that possible?
Another idea I had was displaying OBDII data on the 2nd screen, is there a native app for DUDUOS that has an OBD-Dashboard to display various info? Also, is it possible to connect the DUDU7 to a USB ELM327 interface instead of Bluetooth or WiFi?

Thanks in advance!

Update: I was able to control it using a wireless mouse, it acts completely independent from the main display, which is actually nice. I guess PIP or the launcher doesn't support projecting a window to a second display... it would be a nice feature though 🙂

If your second screen supports TYPE-C input, you can directly connect it with the C port of DUDU7, and the second screen can operate the display content by itself including sound.
If it is USB to HDMI, you can open the Android Settings - Projection Output, there is a projection application Give the application you want to individually project to the second screen by ticking the box, then when you open the application in full screen A projection button will appear in the top drop-down.
