    I bought a chinese video projector: Cheerlux C6. I connected my hdmi to projector but the deepin don't find the other display to connect. Please add suport for video projectors.
    my laptop is a Samsung NP300v5z and it has an intel i5 2410m procesor and nvidia 520mx dedicated video card.

    I am not sure if your projector is officially supported. But electronically is basically a external monitor. A few weeks back I did run temporary display in my Deepin 15 through my HDMI connector and it worked okay. I don't remember if I used xrandr to configure or not. Are you using the default open-source video driver ?

    I see that it does not recognize a connection with HDMI1 and your sure the device is plug in before you turn on laptop.

    I would type enter

    xrandr --listproviders

    Okay thank you for posting the outputs . I see there is 2 providers the intel and the nouveau.
    A hybrid type of graphics card. So my guess for now is one of the proprietary Nvidia drivers
    need to be installed in your driver manager.  Most users had good luck with Nvidia 340.96 and 352.63
    but many had trouble with 358.16 I will take a fresh look at your outputs latter.

    The Optimus technology is well supported in windows but it is some what complicated to get working in Linux
    Basically need to match the right provider with the hdmi connection. there are several methods in Linux to try.
    Either through bios or nvidia or prime functionality of the nouveau or bumblebee
