If you want three separate images on three displays you need three "heads". :rolleyes::rolleyes::rolleyes: Many years ago you could also go FireWire to a device for a Video Viewer additional output.
Well... if you were using the HDMI input to your TV then maybe you were using a USB->HDMI converter?

I've never used one myself, but a couple of the other programmers, at the last shop I worked at, used one to drive a third monitor - and it seemed to be successful. Or, anyway, I never heard any grumbling.
Also. The extended video for the VV usually defaults to the second output on your primary video card. You cannot choose which video out it uses. I am uncertain if video overlay is supported anywhere, anymore. Not on any of my last few computer systems at the very least.
Thanks, everyone. I'm starting to think that I went from a triple-head Matrox (750 sounds right) to the dual-head i7 GPU, at which point I disconnected the TV and just worked from my second monitor for video. Weird how I don't remember stuff, anymore. I'd have thought that would have been a memorable "downgrade." And it seems so against my nature that I would've been okay with that. :confused:
Are your 2 outputs direct or on videoport (I'm not sure of the official name) whips? We had a ton of dells with that port style and a lot of the whips were Ys that split into 4" cables with a blue vga on one and white dvi on the other, maybe you had one of them? - and seven years ago seems about when we were getting them.
