    Tried tinkering with different settings in nvidia control panel and all other suggestions... even tried restoring system from a backup when everything was working fine. But, still only working with VGA attached. When I remove VGA... HDMI loses its signal. Very Puzzling.
    Normally this happens when you cloned the two. In this case, don't. What I dont get yet.. What is the third screen in your snips?
    Make you lt screen primary and do not clone. We'll go from there....
    Snip 4... lt is primary and not cloned. The third screen would be the VGA connected to a TV... has to be connected to see the HDMI screen.

    You mean your VGA laptop output has to be connected to a third screen? Which vga output is that ? Graphics card or does you mobo have one? Or is the vga ALSO connected to the same tv as the hdmi?

    Yes VGA has to be connected to a 3rd screen(second TV in this case) I'm pretty sure the VGA is on the mobo.

    OK, a last check question: if you right click on your screen and go into W7 screen properties (not nvidia) in the case you have the 3 screens connected... what do you get?
    In that screen, please make LT screen the primary and do not clone or extend anything...

    Ok, by default in this case VGA is primary and HDMI is extended. If I make lt primary; no signal on HDMI or VGA but they are listed as 2 and 3. Only way to get signal on either is to clone or extend.

    And you are sure it used to work without cloning?

    Yeah, pretty sure... different resolutions... so that wouldn't be cloning right?

    No, you'd expect it to go for the lowest, maximum res of the two screens and present that on both. So if you are sure there were different resolutions then it was not cloned.

    Please test something strange: Try making TV hdmi your primary screen and when it is.. take out the vga connection. If you need to put things right after because you end up with no screen at all, boot in Safe mode and reset.

    When HDMI is primary and VGA is removed... it switches back to lt and HDMI TV is no longer listed in displays.
