Second HDMI display

HI.
I have M3N WS motherboard (https://www.asus.com/Motherboards/M3N_WS/specifications) with integrated NVIDIA:

(text from manual)
VGA
Integrated NVIDIA ® 8 Series GPU
- Supports HDMITM Technology with HDCP
- Multi VGA output support: HDMI/DVI & D-Sub

Rear panel I/O ports 1 x PS/2 keyboard port (purple)
1 x HDMI Out port

I connected first display to VGA port and the second one to HDMI port. But only first is working (during the boot and after X start).
Output of xrandr:

Screen 0: minimum 8 x 8, current 1280 x 1024, maximum 8192 x 8192
VGA-0 connected primary 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
   1280x1024     60.02*+  75.02 
   1280x960      75.00 
   1152x864      75.00 
   1024x768      75.03    70.07    60.00 
   800x600       75.00    72.19    60.32    56.25 
   640x480       75.00    72.81    59.94 
HDMI-0 disconnected (normal left inverted right x axis y axis)

How to enable video on second display?

Re: Second HDMI display

Check your dmesg and if you are on nouveau you might want to try with nvidia-340xx instead.

Re: Second HDMI display

lspci | grep -E '(VGA|3D)'

Ensure the HDMI cable and monitor work in general (with other HW or OS) and simply re-plug the HDMI cable on both ends while the system is running.

Sorry, but your advise too obvious. Of course such trivial things were tested in the first place.

Re: Second HDMI display

Leaving aside that you *ould have indicated that in your first post: "and what's the lspci output?"

Roina, In case you were wondering where you post went, I think you hit the report link, not the reply link.

Re: Second HDMI display

No hybrid pitfall then.

First of all, the board seems to have an hdmi switch in BIOS, so ensure the hdmi output is enabled there.

Next check whether the device is detected by nvidia-settings.
If not, replace the nvidia blob with nouveau.

If the hdmi connection isn't detected by nouveau either, you're likely facing a hardware issue (cable or jack, the device isn't exactly new)

I didn't find any HDMI settings in BIOS, exept HDMI audio. You can look MB manual in the link of the first message.
Nvidia-settings doesn't see that display.
Also I tried to boot from Ubuntu iso, and it uses nouveau drivers by default, but nothing changed.

With my experience I can suspect (exept really broken HDMI port) only that I use not HDMI-DVI cable from the MB official box, but DVI-DVI with HDMI reconnector screwed from one end. If that reconnector have transmittance only in one direction (then HDMI port is on the display device) then it can explain situation.

Try a plain (and *known* good) HDMI/HDMI cable first.
Rule #1 of HDMI problems is "IT IS ALWAYS THE CABLE!"

I have buy standard HDMI-DVI cable but nothing changed. I decided to give up with this problem. Thank you everyone.
