This output shows (as you already noticed yourself) that the TV is not properly detected (refresh rate and so on). Make sure that the TV is in the right mode. They are called differently dependend on the brand: Gaming/Computer/PC…
Thank you,
I checked the tv, and there are not any gaming/pc etc settings. The only thing close is the picture color presets; movie, natural, dynamic, standard.
As a note, all of the monitors and tv were working on 15.4. Nothing changed on the computer (except disconnecting a bad harddrive), or on the tv.
Correct.
It shows all 4 monitors (3 monitors, 1 TV)
(I am not clear of how to make the change to the Bus ID you suggested above)
What and where is the current xorg.conf file? I used to be able to edit that file as needed. I think I remember that process was changed a few years ago, but I don’t know the current process)
Nvidia X Server Settings / X Server Display Configuration:
On GPU-0 - (GeForce GT710) Bus ID: PCI:1:0:0
DVI-I-1 - (SAMSUNG SyncMaster)
HDMI-0 - (SAMSUNG SyncMaster)
DVI-D-0 - (SAMSUNG SyncMaster)
The 3 monitors configuration is “X screen 0” (and are all active)
On the graphic display each monitor is a grey rectangle with 1280x1024 on each.
On GPU-1 - (GeForce GT 610) Bus ID: PCI:32:0:0
DVI-I-1 - (SAMSUNG)
The tv is configuration is Disabled
On the graphic display each monitor is an orange rectangle with Samsung (disabled) on it.
The Configuration dropdown has and option to: “New X screen (requires X restart)”
I select that, and Configuration now shows “X screen 1”
I also selected Xinerama
Select Apply, error image "The current settings cannot be completely applied due to one or more of the following reasons.
Two of them are - An X screen has been added or removed, and - Xinerama is being enabled/disabled.
Selected “Apply What Is Possible”
Save to X Configuration File: /home/dad/4monitors-xconfig
On the graphic display each monitor is an orange rectangle with Samsung 1920x1080 on it.
Tried this with and without Xinerama.
Log out to restart X, and reboots, both come back with the TV still disabled.
Nvidia settings sees the TV and Monitor Settings (menu/System Settings).
Both ARandR and Monitors show only the 3 monitors and not the TV (menu/Preferences).

@idee If you edit that file and change the Option "MultiGPU" "Off" to On in the screen section and save as 20-nvidia.conf then as root user copy the file to /etc/X11/xorg.conf.d/ directory and reboot. If you get to a VT and not desktop or just blank screen, just switch to a VT via Ctrl+Alt+F1, log in as root user and delete the file and reboot.
