I have a Gigabyte GTX 550 Ti card. It has two DVI slots and one mini-HDMI port.

I use the DVI port with my monitor, and wanted to try to use the HDMI with my TV. So I connected it, but no image appeared. Weird, I thought. So I rebooted and logged on to both Windows and Ubuntu, and yet the only screen with an image was my monitor. I turned the PC off, disconnected the DVI cable, leaving only the TV connected to the HDMI port. Turned the PC on and there we go! I had an image.

Then when I was done I wanted to go back to my monitor so I connected the DVI cable back to the DVI port, but nope, no image. Had to again reboot and disconnect the HDMI cable for it to work.

How can I get them to work at the same time?

Or at least be able to switch between them without rebooting?

You need to set the multiple display settings in the Nvidia Controll panel. Right click on your desktop and select Nvidia control panel. Next select Advanced settings, Then on the left hand pane expand the display option and select set up multiple displays. Have your TV plugged in and select which option you want. Clone (same picture on both the TV and the monitor) Dual view (Tv and monitor are treated as two separate displays) Horizontal span (expands the windows desktop to cover both displays) or Vertical span (same only the monitors are arranged vertical instead of horizontal)
