Selecting External Display Output when more than 2 monitors connected.


Is there a limit on the number of displays shown in the External Display Output sub menu is I've never seen it display more than 2 display even though I currently have 3 displays connected. Sometimes is shows Display1 and Display2, sometmes Display 2 and Display3 and sometimes (like now) it shows Display1 and Display3.

It seems to be random as to which displays it shows on each Startup and causes me problems when Display 3 isn't listed as that is the display I use to provide a display feedback to the talent as to what is going to air.

Is it possible to get this to support all connected displays as I would actually like to have 4 display connected but haven't been game to connect a 4th display as I'm having enough issues with the 3 displays.

I'm running Wirecast 7.5 on 64-bit Windows 10 version 1607.

The PC is a Dell Precision 85810 Workstation with the following configuration.
- Xeon E5-1660 v4 CPU
- 32GB Ram
- 512GB Solid State Drive (for OS and Wirecast)
- 3x 1.2TB SAS Drives in HW RAID 0 (for Video storage during recording)
- NVidia Quadro K1200 (connected to 2x Displays and 1x TV)
- Black Magic Design DeckLink Quad 2 (connected to 3x Sony cameras via SDI)
- Behringer Xenyx QX1204USB (connected via USB)

Displays and TV are correctly seen by Windows.

  • If I understand you, you have 3 total monitors hooked up (2x Displays and 1x TV). It should show the two external displays. Just to be clear, your GPU can otherwise use all your monitors at the same time in other programs or the OS? Also make sure none of the monitors are "mirrored."

    You mentions "Display 3" but in your description below that you mention 3 displays total. If you have 3 total displays, one is considered native and the other two would be external.
