Yeah, already tried that too. First post says, "Changing the main display to TV doesn't seem to make a difference." I imagine if there's a fix for this, it has something to do with that function though, so I'll keep playing with it.

Toyed around with trying to duplicate the desktops, but it looks very sloppy and is kinda a crutch solution. No matter which monitor the window is in, it always snaps to the first.

I've got a three monitor setup on my rig with my main monitor on far left, smaller monitor in the middle, and then a small TV hooked to my computer on the right with a HDMI. I'm trying to get LFS to fullscreen on the TV because that's where my wheel sits, but everytime I shift+F4, it automatically switches to the left monitor. Changing the main display to TV doesn't seem to make a difference. Don't really know what to do here, looking for some help. If it's worth mentioning, I'm running a GTX 670.
