iMac: Turn primary screen off while boxee is open

[neutrino15]

Hello,

I am using Boxee on my TV which is configured as the secondary screen on my Intel white iMac. Is there a way to turn off (as in, shut off the backlight) on my iMac's primary display while keeping the secondary display (my TV) enabled? I tried to use SleepDisplay (http://linestreet.googlepages.com/) to turn off my iMac's screen, but it also shuts off the signal to the TV (forcing my TV into the sources scan mode)

Does Boxee have an option to do this? Are there any third party solutions? Any hacks even?

Thanks--

Thank you for revealing that setting! I looked all over the internet for over an hour trying to find a solution!

I man-love you!
