Can a graphics card output a picture through two cables at the same time (for example both mini-HDMI and DVI) without issues?
The reason I ask is I currently have everything (PC, 360, PS3) wired up to an Onkyo 5.1 surround system - but that only has one picture output as far as I know - to my TV, which is 32". I've been using this as a monitor for a while for convenience, but I don't want to do that long term if I don't have to. I'd prefer to have a separate, smaller monitor for the PC, and the TV for 360/PS3, but still have all 3 connected to the 5.1 speakers through the AV box, as they are now.
Currently, the PC is plugged in to the AV receiver via the mini-HDMI port on my GTX 460 graphics card (using a mini-HDMI to HDMI cable), which outputs both sound and video signal down the one cable. I think the simplest solution, if possible, would be to leave this as is, and then run a DVI cable at the same time from the graphics card to my monitor, when purchased. Then, hopefully, I can set the AV receiver to the PC setting as normal (the TV doesn't need to be switched on for the surround sound to output), and switch on the monitor, and receive a picture on the monitor, and sound through the surround speakers. Would this work fine?
Thanks for any advice.
