I'm having an issue with a dual monitor setup that's driving me mad. I've got two screens connected via HDMI - one directly to my main monitor, the other to a Sony AV Receiver which then outputs video to a HDTV which I use as a second screen sometimes and audio to a 5.1 setup. Normally i'm able to run both or either one of the screens independently without any issues. However I recently re-installed windows on my machine and now if the HDTV is off, the other monitor will go black. If i try to boot the computer without the HDTV on, it will continually restart and the monitor will remain black. Ultimately, I can't use the PC without the HDTV on.
I can't seem to figure out where the issue is. The wiring hasn't changed at all, so that's not the issue. I'm assuming it has to be with the video drivers or in the video settings. I've updated the video drivers to the latest version but the problem persists.
Any suggestions would be welcome!
