Yes that is normal, when its off screen on one monitor it actually on the other monitor. If you had them side by side you would see it go from one to the other.
Okay, step by step...
Step #1 - Restore to Dell Factory image (only the computer monitor connected).
Step #2 - Plug in TV HDMI cable and turn the TV on. A second monitor is automatically setup in extend mode. I click the Identify button and the TV displays 1 and the computer monitor displays 2.
Step#3 - I change the mode to Duplicate (from extend). My desktop flips to the TV while the start screen and metro apps stay on the computer screen. I click the Identify button and the TV displays 1|2 and the computer monitor displays 1|2.
I have run out of things to try. The damn thing won't work.
The only way to get my desktop back on the computer monitor is to unplug the TV HDMI cable. That work-around is too crude for me to use. I would prefer to go back to my old setup of Video via DVI->HDMI->TV and Audio via SPDIF-Out->Surround Sound.
My old method was cumbersome. But at least I didn't have to plug/unplug devices when I used them.
I don't know what is going on with your system. If I switch from extend to duplicate two of my monitors show the exact same thing. The mouse cursor shows on both monitors in the exact same position. If I'm in Metro, it s on both displays. If I switch back to the desktop it mirrors on the second display exactly. My third monitor just goes black with a no signal message. In duplicate I cannot display Metro on one monitor and desktop on the other. As far as I know the video card output sets the monitor number. You can't change that, all you can do from Windows is move them around to match your physical location.
I have been chatting with Dell Support for a couple of hours. We updated the Nvidia Video Driver, the Chipset Driver, and also updated the BIOS.
The problem still occurs when I power off my Surround-Sound/TV/system. Somehow the power-off event causes my two monitors to go into Extend mode (not Duplicate/Clone mode as originally setup). I can tell they are in Extend mode because if I mouse over the Control-Panel-Display icon on the taskbar, I can see the extend/two monitor logo instead of the duplicate/one monitor logo. The desktop stays flipped to the turned off TV until I unplug the HDMI cable.
The desktop comes back after I unplug the HDMI cable because the cable unplugging event reconfigures to a single display.
Then your tv is the issue. It is not cutting signal when it should be doing so. It's keeping the channel (of communication) open so-to-speak, even when powered off.
A good test to see what happens is if you leave HDMI in, but unplug tv from the wall.
Maybe there is an option on the tv OSD settings to alter this behavior.
I don't actually plug the HDMI cable into the TV. I plug it into the Game port of a Marantz AV7005 Surround Sound System.
Then the HDMI signal from this game input (or one of many other sources) is then routed to the TV. The TV has an HDMI control option that tells the surround system when the TV is shut off, so that the Surround Sound system can also shut off. Though, it doesn't actually shut off. It goes into standby mode.
If I unplug the Marantz AV7005 then Win8 automatically reconfigures to one monitor and automatically reconfigures back to two monitors when I plug it back in.
Try the other output port on the Marantz.
The ARC channel may be what is keeping things alive. Try other port, yep.
Heck, try different input ports while you're at it, too.
See if that has some settings you can alter about it. Probably not as it doesn't seem so to me, just by looking at it.
I found this gem in the manual:
• When “HDMI Control” is set to “ON”, it consumes more standby
power. If you are not using this unit for an extended period, it is
recommended that you unplug the power cord from the power outlet.
• “HDMI Control” does not work when the power to the equipment is off.
Either turn power on or set to standby.
• The HDMI control function controls operations of a TV that is compatible
with the HDMI control function. Make sure that the TV and HDMI are
connected when you perform HDMI control.
• If the “HDMI Control” settings have been changed, always reset the
power to connected devices after the change.
Thanks. I got it working now. Instead of connecting PC->AV7005->TV I connected PC->TV->AV7005 using the HDMI(ARC) feature to carry sound from TV->AV7005.
I use the the HDMI(ARC) feature because I have an over-the-air antenna (actually two, one pointing to San Francisco, and a second pointing to Sacramento). I need the the HDMI(ARC) feature to carry sound from the TV to the AV7005. It works quite well (even with surround sound).
Next I need to give a few details in a separate post as to how this works (terribly) in Win8...
