I have a GEforce GTX 750 video card, and set up two displays.

In vMix-HD, am able set display1 to be fullscreen output, but I do not see any option to use display2 as an external output.

> Is it possible to configure vMix to use display2 as a fullscreen or external output ?

My setup:
nVidia control panel
WXGA output is display 2, but I have set it to primary (where the vMix applicaton runs)
HDMI is display 1 - I have an HDMI to s-video scaler to hopefully use this for existing SD TVs.

If there is another way to configure the outputs of the graphics card so I can get fullscreen output, please let me know.
I am planning to stream, record and use fullscreen output if possible.
Using Decklink Quad card for (4) SDI inputs.. cannot use one of them for output at this point.

Gary

The "Full Screen" button is designed to send selected source to secondary output of your graphics card to drive devices such as projectors or even another monitor if you wish to see a larger form of the a selected source. You could also choose a multiview for a producers view .
External button is designed to activate output to web streaming connection if you using program such as flash media encoder and also to send video audio to secondary output I/O such as a BlackMagic Intensity Pro card for external video devices.

I upgraded to the latest release of vMix HD for this recent test.

I revisited the system and my configuration settings again today and can see that the full screen output is showing on the display that is designated as the primary display in Windows. I was able to steer the full screen output to either one of the two monitors connected to my GTX 750 card, but only to the one that is designated as the Primary display in Windows 7.

In other words, the Fullscreen output shows on the display where the Windows Start menu is... and where the desktop icons are typically located.

This seems inconvenient, because if I am using full screen for vMix output, I would not want to see any other computer activity like launching programs in the full screen output. While full screen is active, I have to use the Windows key to break out and do anything else (like run vMix on the other display).

Is this normal to see the Fullscreen output on the primary display (display1) and run vMix from the secondary display where there is no ability to launch other programs like a web browser, etc.?

Gary,
My guess is that in your case it is a simple fix. In vMix Settings/Display, Fullscreen section select "2" in the dropdown "Display" under "Fullscreen 1" (green rectangle).

Background: This is unfortunately a nomenclature and Windows display management mess, for many reasons.

To begin with, Windows seems to number the available displays in an arbitrary fasion. Perhaps not arbitrary, but I have not after several experiments been able to figure out how Windows number the displays. No success either in finding out if the numbers somehow are related to which connector is used on the graphics card (eg Displayport, HDMI, DVI, etc).

Second, Windows's numbers for "Display" are NOT the same as the numbers shown in vMix's dropdown selection discussed above. vMix always use "1" for the display where vMix is running. In case of more than two monitors are connected, one has to figure out which goes where by trial and error.

To make things even more complicated we have issues when more than two monitors are connected. Consider an example where vMix is running on one monitor (say Windows's display 2), one monitor is used to feed vMix's Output to an IMAG screen (say Window's display 1), and the third used to feed vMix's Multiview to a monitor used by a production assistant (say Window's display 3). Again, you have to use the trial and error to figure out which Fullscreen numbers should be set in vMix's Settings/Display. Now you happily save this Setting at home/office/studio and everything works.

Then, on site, when booting up not all monitors are connected. Perhaps because you have to wait for the house technicians to deliver the cables. Most likeley the house monitors are not the same as you had back "home". Which means that whatever you set in Windows in terms of resolution and frame rate are forgotten. And probably the "numbers" are no longer the same. Again, you have to use trial and error to make everything go where you want it to go. Again, this is not vMix's fault, it is Windows's. Of course things are better if you always produce in the same location, with the same monitors connected to the same outputs and all monitors are connected at bootup.


Personally, to reduce confusion, I would prefer if vMix's "Display 1" and "Display 2" (the latter for editions where two Fullscreens are available) allowed the user to rename these (green rectangles). Default would be "Fullscreen 1" and "Fullscreen 2", and I could rename them to for example "IMAG" and "Assistant". These names should then also be used in the "Fullscreen" dropdown selection at vMix's main window. And perhaps instead of "Display": 2, 3, and soforth (in the Settings/Display) - use "Output": 2, 3, and soforth (to clarify it is not Windows's display numbers.

Just my two cents...

Glad to help, and happy to know you fixed it!

I think Martin said earlier in another topic where these issues was discussed, that vMix cannot know which display is which. So he designed it to make vMix's Main screen to be on what vMix offers as Display drop down 1, and 2..4 are other displays, with no relation to Windows's numbering.
