no hdmi output

English Multimedia
#1

Hi, I already reported this error, but I bought a new graphics card, reinstalled the system and the error disappeared.
Now it appeared again. My graphics card is nVidias’ GM107 [Geforce GTX 750 Ti] with tree outputs DP, DVI-D and
HDMI . Only the first one appears in Systemsettings->Displays.Adequatly

# xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 
DP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
   1920x1080     60.00*+  59.94  
   1680x1050     59.95  
   1280x1024     60.02  
 ...
DMI-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)

I switched Intel graphics from the motherboard off.

Could somebody help me, please how to put my computer screen on TV, which already has been working ?

I found no errors in logfiles. lspci shows:


# lspci -k -s 03:00.0
03:00.0 VGA compatible controller: NVIDIA Corporation GM107 [GeForce GTX 750 Ti] (rev a2)
        Subsystem: ASUSTeK Computer Inc. Device 84bb
        Kernel driver in use: nvidia
        Kernel modules: nouveau, nvidia_drm, nvidia

Adding boot options like video=HDMI-1:D or changes in BIOS setup won’t help.
Yet I see from the above that the device is properly recognized, but it’s output hdmi is “disconnected”

Some people installed the driver directly from nVidia, I installed packages with nvidia-glG04
Also


# xrandr --output HDMI-1 --mode 1920x1080 --rate 60
xrandr: cannot find mode 1920x1080

What could I check else ?

Hi
What about;


xrandr --listproviders
xrandr --listmonitors

I would also suggest checking what mesa packages are installed and then forcing the re-install;


zypper se -i Mesa
zypper in -f <list of your installed Mesa packages>

    output DP-2
# xrandr --listmonitors
Monitors: 1
 0: +*DP-1 1920/510x1080/287+0+0  DP-1

i.e I have only one monitor !

And now I have two monitors

# xrandr --listmonitors
Monitors: 2
 0: +*DP-1-1 1920/510x1080/287+0+0  DP-1-1
 1: +DVI-D-0 1920/510x1080/287+0+0  DVI-D-0

This is very nicy, but I’d prefere if the second is HDMI-1

#6

Hi
What desktop environment? Should be a display setting somewhere to switch the monitor over if it’s connected to HDMI output…

Hi
So it looks like it is seeing the GPUs and Monitors, so you are plugging in the HDMI connection on the GPU, what connection on the monitor (DVI, VGA, HDMI)?

#11

Hi Malcolm, I see only two rectangles in Systemsettings -> Screens. There are “EV2335W DP-1-1” and “EV2335W DVI-D-0”. EV2335W is my EIZO monitor. Two outputs DP and DVI-D are connected to this monitor. I can move these rectangles, unite them or split apart. This is OK.

DVI-D is comming from the GM107[GeForce GTX 750 Ti] graphical card in expansion slot and DP from UHD Graphics 630 integrated on the motherboard - this is just for sure, if expansion GPU won’t work.

But earlier I had also the third rectangle for HDMI output, which is connecting GeForce graphical card with the TV screen. Now I don’t see it. No signal is coming to the TV.

#12

Hi
If you disconnect the monitor from the UHD card does the HDMI output start?

#13

I disconnected DVI-D, but HDMI won’t start.

#14

I searched for the solution on the Internet, but I found nothing. I remember that the problem appeared some time ago and an edition of some file in /etc/X11/xorg.conf.d has helped, but now I cannot recall it.

The problem still exists.

#15

It happened to me before on an LG tv.
HDMI connection sometimes get lost.
I need to transfer the HDMI chord on a different
slot of the HDMI of tv and find which one works
or detected. The tv also should be connected
permanently on my machine else HDMI will not work.

#16

Hi
The other option is to force the HDMI output at boot time, add the following via YaST bootloader to the kernel command line options;


video=HDMI-1:e
#17

Hope I posted a question before witn the LG tv. I didn’t know that I can have the above option in the bootloader.
bookmarked this as reference going forward.:wink:

#18

No, adding this boot parameter won’t change nothing. I tried also other boot parameters - they don’t help.

Yet I remember, a year ago adding some hdmi line in one of /etc/X11/xorg.conf.d files has helped. But I cannot restore now what it exactly was.

#19

I think I’ve seen this before,It might be in my bookmark, I will try to find it for you.

Meanwhile you said you are using kde. Try disabling kscreen2
I always disable it in background services in the systemsettings.
Plug your hdmi reboot.

You also said you switch off your intel card? You should switch your nvidia card as primary too.

See the ouptput of

xrandr | grep connect
#20

Hi Conram, I disabled kscreen2. I even don’t know what is it for. nvidia is my primary card

# xrandr | grep connect
DP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
HDMI-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)

The adjustment in /etc/X11/xorg.conf.d was as if lines:
1920x1080 60.00*+ 59.94
1680x1050 59.95
has been added somewhere.
