HDMI not working on XPS15

Hi, I've got an up-to-date XPS15 (L502X), and can't seem to get my HDMI output working,

My display adapters are the following (only the Intel one should be managing the desktop):

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
        Subsystem: Dell Device 050e
        Flags: bus master, fast devsel, latency 0, IRQ 42
        Memory at f1400000 (64-bit, non-prefetchable) [size=4M]
        Memory at e0000000 (64-bit, prefetchable) [size=256M]
        I/O ports at 4000 [size=64]
        Expansion ROM at <unassigned> [disabled]
        Capabilities: <access denied>
        Kernel driver in use: i915
        Kernel modules: i915

01:00.0 VGA compatible controller: nVidia Corporation Device 0df4 (rev a1) (prog-if 00 [VGA controller])
        Subsystem: Dell Device 050e
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at f0000000 (32-bit, non-prefetchable) [size=16M]
        Memory at c0000000 (64-bit, prefetchable) [size=256M]
        Memory at d0000000 (64-bit, prefetchable) [size=32M]
        I/O ports at 3000 [size=128]
        Expansion ROM at f1000000 [disabled] [size=512K]
        Capabilities: <access denied>
        Kernel driver in use: nvidia
        Kernel modules: nouveau, nvidia, nvidiafb

And even though my HDMI external screen is connected, xrandr shows:

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
LVDS1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
   1920x1080      60.0*+
   1400x1050      60.0  
   1280x1024      60.0  
   1280x960       60.0  
   1024x768       60.0  
   800x600        60.3     56.2  
   640x480        59.9  
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)

I've tried to xrandr --output HDMI1 --auto, but didn't change anything. Does anyone know what could I try?
