HDMI to TV Monitor Not Working

Post by capeannlinux »

Unable to mirror my laptop display to TV Monitor - the laptop sees the TV monitor and displays it, but when selected it just blinks and will not make connection.

I tried Alt-F2 - r to reload x window but no effect. This same HDMI cable and TV monitor has worked for years with Mint 17.1 and this laptop (specs below). Anyone else having this problem? Has something changed in 19.1 that might affect this? Very happy with Tessa otherwise.

You mean the monitor is seen in System Settings > Display and it is turned ON?

Use these commands and post the output: xrandr --prop and ls /sys/class/drm

What is the brand and model number of the TV and are any adapters use to connect it?

Yes - Mint Menu - Display - and on laptop both its screen and TV Monitor are shown. TV is Westinghouse 32" Model# SK32H640G - turned on of course and set to HDMI2. Laptop is connected by HDMI cable to HDMI2.

Output you requested -

You can test this kernel parameter by editing the kernel command line. The effect will only last for one session. At the GRUB boot menu select the correct line but don’t press Enter. Press the “E” key to edit. If no menu shows, then hold down the shift key while starting. Use the Down arrow key to go down to the line that starts with:
linux /boot/vmlinuz.............ro quiet splash $vt_handoff

Go to the end of the line. Add a space and then type this kernel parameter: video=HDMI-A-1:e

Press F10 to start your system.

roblm -
Followed your instructions to the letter - edited Grub line as you said - booted out, but unfortunately, same exact results mentioned above - tried a second monitor as well. It's not urgent that I connect this particular laptop to my TV, but happy to continue to help LM troubleshoot this problem.

Open the Display program and try selecting different resolutions for the TV. Open the TV’s on-screen menu and try selecting different input modes and then select the original.

Try using these commands, one at a time:

Code: Select all

xrandr --output HDMI-1 --mode 1366x768 --rate 60 --right-of LVDS-1
xrandr --output HDMI-1 --off && xrandr --output HDMI-1 --mode 1366x768 --rate 60 --right-of LVDS-1
If that fails, then use this command to remove the monitors.xml file. It’s not needed and will conflict with the next procedure:
rm ~/.config/monitors.xml

Create an xorg.conf file: sudo touch /etc/X11/xorg.conf
Open the file for editing: xed admin:///etc/X11/xorg.conf

Add these lines:

Code: Select all

Section "Monitor"
   Identifier    "Monitor0"
   HorizSync       30.0 - 70.0	   
   VertRefresh     50.0 - 75.0
   Modeline  "1366x768_60.00"  73.25  1366 1406 1438 1496  768 771 776 816 +hsync -vsync
EndSection

Section "Device"
   Identifier   "Device0"
   Driver   "modesetting"   			
   Option "Monitor-HDMI-1" "Monitor0"  
EndSection

Section "Screen"
   Identifier   "Screen0"
   Device   "Device0"
   Monitor   "Monitor0"
   DefaultDepth   24
   SubSection     "Display"
      Depth       24
      Modes "1366x768_60.00" 
   EndSubSection
EndSection
Logout and back in. If there is a problem getting back to the desktop, then press Ctrl+Alt+F1 to enter the virtual console tty1. Use this command to remove the xorg.conf file and reboot: sudo rm /etc/X11/xorg.conf; reboot

Re: HDMI to TV Monitor Not Working

I have switched to testing with a 19" computer monitor. I haven't tried the tests / commands you sent, but maybe this will tell you something. At this point I can see that the display is being mirrored but is misaligned. So I have a blank screen on the test monitor (HDMI connected) - As I move my mouse cursor to the right edge of my laptop screen, the cursor disappears off the laptop display and appears on the monitor, coming in from the left. I can do the same thing with a window - minimizing a full screen window slightly, and click-dragging it to the right, it will then appear on the monitor as it exits the laptop display - this only works left to right, not right to left. To clarify - going to the right with the window on laptop display until only the left half of window remains, the right half of the window clearly appears on the monitor but is flickering. It sounds like some of kind of scaling issue?

You have an extended desktop, not a mirroring of the laptop and monitor displays. To change this, open the Display program and mark the checkbox next to Mirror Displays.

I've tried toggling the Mirror Display option multiple times at every test - of course I would do that. Checking / unchecking the Mirror Display box has no effect - that's the problem. My solution is to use my Mint 17.1 laptop for HDMI to TV - for some reason that earlier version (and my Ubuntu laptop) mirror the displays with no problem. Surely do appreciate your attempt to help though.

For those of us who's adding the quoted video kernel paramter worked, but no external HDMI detected/shown when re-booting back with the boot process happening normally, what do we do from here? Everything else is basically the same as OP's problem up to this point.
