I have 2 monitors and 1 TV hooked up as a monitor to a 660 ti GPU (this works when all on). When the TV is off, there is no visible device to extend a display to but when it's on there is. I wanted to use the TV to display Windows Media Center in another room but every time the TV is turned off, the display effectively vanishes.

Is there a way to make the TV device persistently "known" by my Win 7 PC? I might as well be pulling the HDMI cable out every time I'm done using it which is absurd.

Related: When I turn the TV off if I was playing a game on another monitor, the GPU seems to re-poll all connections and I have to minimize and resume my game for it to display again. If it didn't have to remove the TV device or whatever it's doing, then I imagine this wouldn't be a problem.

To clarify - I require a solution that works around what is expected since what is expected is not good enough.

Expected behaviour. When your TV turns off it switches off the power to the HDMI port so your computer thinks you have disconnected the device (HDMI is plug and play like USB). This setting is likely changed on your TV (put to sleep instead of turn off) and not much you can do on the computer.

A product like this will theoretically keep the display info alive.
