Problem
Meine ASUStek STRIX-GTX1050TI-O4G-GAMING Grafikkarte hat 4(!) Anschluesse 2 x DVI-D, 1 x HDMI 2.0b und 1 x DisplayPort 1.4.
Einmal ist es mir tatsaechlich gelungen vier Monitore gleichzeitig mit einem Bild zu versorgen. Sobald aber ein Monitor ausgeschaltet wurde, war eine Reaktivierung nicht mehr moeglich.
Da zwei Monitore TV-Geraete/Beamer sind, wollte ich nicht ein riesiges Display, bei dem alle Screens nebeneinander liegen, sondern einzelne Screens (3) um Programme leichter direkt auf einem Screen platzieren zu koennen.
Das schlimme ist, durch die vielen Versuche ging alles irgendwie immer weniger, bis ich zum Schluss, egal welche Kombination ich waehlte, nur noch einen Monitor und einen TV ans laufen bekam.
Loesungshinweise
Leider steht im Datenblatt kein Hinweis auf die maximale Anzahl gleichzeitiger Nutzung von angeschlossenen Monitoren. Also gehe ich mal davon aus, dass solange die maximale Displaygroesze von 7680x4320 nicht ueberschritten wird, bis zu vier unterschiedliche Bilder ausgegeben werden koennen. Bei vier FullHD Screens sollte also, die maximale Displaygroesze weder horizontal noch vertikal ueberschritten sein.

DDC communication failed
I2C/-0 wird nicht erkannt, der HP hat kein DRM und der Sony hat ein Kommunikationproblem. Na toll.
Hier ist der Grund: Der Sony am i2c-3 hat keinen DDC-Chip (Adresse 37), sondern nur einen EDID-Chip (0x50). Der Samsung am i2c-0 hat weder noch und wird somit erst gar nicht erkannt.

Slave addresses x50 (EDID) and x37 (DDC). xrandr has ways other than I2C to access the EDID, e.g. by BIOS calls Daraus koennte man jetzt schlieszen ,dass i2c-0 DVI-D-0, i2c-1 DVI-D-1, i2c-2 DP1 und i2c-3 HDMI ist.
Anzahl Anschluesse/Displays/Screens
Hinweise aus dem Netz
Also ich glaub die ganze gtx 1000 Serie unterstützt 4 Displays. Sonst kannst du einfach an die onboard was anschließen oder ne 2. Grafikkarte nehmen
Das ist schon korrekt, viele Grafikkarten können nicht mit 3 Bildschirmen umgehen, auch wenn mehr Anschlüsse vorhanden sind. Dies ist auch vom Hersteller abhängig. An meiner GTX 1050 TI Asus ROG Strix kann ich z.B. problemlos 3 Bildschirme betreiben.
Wenig hilfreiche Hinweise gibt es auch. Gut find ich das mit dem VGA-Tipp;-))
Viele Foreneintraege koennte man sich sparen, wenn man einfach mal die Dokumentation liest.
Most NVIDIA GPUs based on the Kepler¹ architecture, or newer, support driving up to four display devices simultaneously. Most NVIDIA GPUs older than Kepler¹ support driving up to two display devices simultaneously.

Was mir auffaellt.
- DVI-D-0 ist connected, aber nicht enabled
- HDMI-0: Der angschlossene Sony TV ist nicht connected
- DVI-D-1: Der angschlossene Samsung TV ist nicht connected
Vielleicht hilft die Option "ConnectedMonitor".
Option "ConnectedMonitor" "DVI-D-0, DVI-D-1, HDMI-0, DP-1"

Was schon mal auffaellt, obwohl 2 Monitore an 2 unterschiedlichen Displayports angeschlossen sind taucht nur ein Monitor0 auf. (NB: VendorName "Unkown" Wer hat denn da wieder geschlafen?)
NVidia xorgconfoptions [5] nur fuer den Treiber 325.15 verfuegbar(???).
Die beiden Options von Interesse sind:
- nvidiaXineramaInfoOrder
The option string is a comma-separated list of display device names. The display device names can either be general (e.g, "CRT", which identifies all CRTs), or specific (e.g., "CRT-1", which identifies a particular CRT). Not all display devices need to be identified in the option string; display devices that are not listed will be implicitly appended to the end of the list, in their default order. Note that nvidiaXineramaInfoOrder tracks all display devices that could possibly be connected to the GPU, not just the ones that are currently enabled. When reporting the Xinerama information, the NVIDIA X driver walks through the display devices in the order specified, only reporting enabled display devices.
- MetaModes (GroszKleinSchreibung?²)
This option describes the combination of modes to use on each monitor when using TwinView or SLI Mosaic Mode. See Chapter 12, Configuring Multiple Display Devices on One X Screen and Chapter 29, Configuring SLI and Multi-GPU FrameRendering for details. Default: string is NULL.
²Just as in all X config entries, spaces are ignored and all entries are case insensitive.
Diese Seite bringt hoffentlich Klarheit.
Wenn auf der GPU mehrere X-Bildschirme konfiguriert sind, versucht der NVIDIA X-Treiber, Anzeigegeräte und GPU-Ressourcen für diese anderen X-Bildschirme zu reservieren (unter Berücksichtigung der X-Konfigurationsoptionen „UseDisplayDevice“ und „MetaModes“ jedes X-Bildschirms) und weist dann alle verbleibenden Ressourcen dem ersten auf der GPU konfigurierten X-Bildschirm zu.
Was bei meiner QuadroM2000Config weiterhin irritiert, ist dass der 2. Monitor keine eigene Section besitzt und nur ueber DP-0 in den MetaModes auftaucht.
The details of how this works are documented in the nv-control-dpy.c sample NV-CONTROL client in the nvidia-settings source tarball.

Hier zum Nachvollziehen.

Was auffaellt.
- Removed Option "metamodes" "DP-1: nvidia-auto-select +0+0, DVI-D-0: 1920x1080 +0+0" Warum? Das muss doch rein!
- Option "DPMS" bei den TVs muss/sollte raus!
- Option "Enable" "True" kann eigentlich bei allen Monitor-Sections rein.
Darueber hinaus kann vielleicht
Option "ConnectedMonitor" "DVI-D-0, DVI-D-1, HDMI-0, DP-1"
auch nichts schaden?
Reboot oder systemctl restart display-manager. Erfolg gleich Null. Nvidia erkennt die ausgeschalteten (Stand-by) TVs nicht.

Warnings:
Block 1, CTA-861 Extension Block:
IT Video Formats are overscanned by default, but normally this should be underscanned. Video Data Block: VIC 31 is the preferred timing, overriding the first detailed timings. Is this intended? Add a Colorimetry Data Block with the sRGB colorimetry bit set to avoid interop issues.
Failures:
Block 1, CTA-861 Extension Block:
Missing VCDB, needed for Set Selectable RGB Quantization to avoid interop issues.
EDID:
Base EDID: Some timings are out of range of the Monitor Ranges: Vertical Freq: 24.000 - 60.317 Hz (Monitor: 48.000 - 62.000 Hz)
EDID conformity: FAIL
Damit koennte man wenigstens einen EDID Emulator fuettern, oder ein Custom EDID.bin in der xorg.conf hinterlegen. Mit
cat EDID.txt | grep -E '^([a-f0-9]{32}|[a-f0-9 ]{47})$' | tr -d '[:space:]' | xxd -r -p > EDID.bin
kann man den Hexcode-Block in eine EDID.bin schreiben.
Teilerfolg
Mit der von Hand korrigierten xorg.conf (s.u.) und nach einem
systemctl restart display-manager
war auf einmal alle Screens vorhanden. Sogar der Samsung der gar nicht angeschlossen war. Beim Samsung stimmt nur die Aufloesung nicht.
Lediglich die Reihenfolge, bzw. Zurodnung der Screens zu den Bildschirmen war vertauscht.
Gute Dienste leistet da der Remote Desktop Viewer, der zeigt ALLE Screens in einem Fenster!
