I am a videoartist who for the first time needs to mix recorded video pieces (AVI files) and send the output to a projector to accompany a live musical performance. I am able to send the full mixing screen to my projector but cannot work out how to just send the mixed 'output'. I am attempting to use a Dell Studio 1555 with a ATI Mobility Radeon HD 4570 graphics card (DirectX 10.1, Shader 4.1, Features Open GL 2.0, PCI-E 2.0 x16, Powerplay, DisplayPort support up to 2560x1600, HDMI support up to 1920x1080 (both with 7.1 AC3 Audio), 1x Dual-Link/Single-Link DVI, 1x Single-Link DVI Support) I have searched vMix help/forums but I cannot work out a solution (if there is one)Do any members have any idea if/how I can do this with this kit? Thanks. Maurice

Try the Fullscreen output described here:

You will need to configure Windows to output to dual displays.

Assuming you have both your monitor and the projector connected to your PC, you have to send your desktop to "Extend" mode rather than "Duplicate". The easiest way is to press the Windows key + P, and then select the Extend option.

Once you have the desktop extended, use the Fullscreen option as Martin ("admin") mentioned.

There are multiple options for an output screen.

1. Run your vMix windows from your video card. You then can install a Black Magic Intensity Pro or Black Magic DeckLink Mini Monitor. vMix will recognize these video cards and you will be able to send the fullscreen output via these cards.

2. Most higher end video cards support 3 or more outputs. You can use outputs 1 and 2 for vMix and any other windows that you want. You then use output 3 or higher for your vMix output screen. Some video cards may require an active DisplayPort adapter for use of any displays over 2.

The downside to using an Intensity Pro or DeckLink Mini Monitor is that you are limited to 1080i60. Most video cards should be able to do 1080p60. Links for these products are below.

Another important factor to consider is the inherent "Video Delay" that is not always palatable in a live music environment. Outputting to the second screen of a dual display, as Martin suggests, may offer the least amount of delay and is certainly a readily available option with most video cards as opposed to using additional capture/output cards.

Thanks everyone for your thoughts on my "problem". I began with the cloudmediagroup's (Seth?) proposal first (being the one requiring no additional hardware) and worked through the screen setup procedure via the Desktop then into vMix settings and there it was...the mixed output, was projected on the wall. I now just have one very minor issue when coupling the lap-top to the projector, the resolution of the lap-top screen is changed to a lower resolution (to match projector resolution?)The consequence of this is that the line of video inputs at the bottom of the screen are now physically larger and so I get fewer visible and need to scroll right to see/cue all inputs (currently 7). Once again thanks everyone for attending to the basic problems of a very new newby. Maurice

Thanks Seth, I'll give that a try.
