Auto switch HD5570 card with VGA/DVI and HDTV on HDMI port

I added a HDTV to my computer. Yesterday I did something where when I turned off the TV the display would AUTOMATICALLY switch back to my secondary monitor and if I turned the TV back on it would automatically switch back to the TV. When this happened I had extend display #1 to HDTV selected. I did not have to manually switch over the displays.

This morning the only way I can get them to switch is by doing it manually through the settings.

Does someone know what I may have done to make the monitors automatically switch without having to do it manually?

Its almost like the computer knew through voltage or something that made it "know" the HDTV had been turned off so it went back to secondary monitor on its own. I want screen #2 and HDTV to switch by themselves like that all the time through the power button.

Is it possible to do that or was that just a glitch in my machine?

(EDIT: **IDEALLY** I would like to get all 3 monitors running at the same time so I can work on #1, Take notes ect/have extra work space on #2 and have music videos, studio software, movies, Tweetdeck news tickers or other stationary items on the HDTV but I think in order to have all 3 monitors running you need some kind of special dongle or something. The way it is right now is Monitor 1 is always on and I have to decide if I want to use monitor 2 or the HDTV. The unused one goes black.)

That is not happening here.

Picture 1 is how it was before I Got the TV with the 2 monitors. AFter I go into settings, monitor #3 is greyed out. After I select extend desktop to TV then it goes to the TV but monitor #2 turns off like in the 2nd picture.

As for "switching", I meant switching displays. With the added in now, I somehow got it yesterday that when I turned off the TV the dislpay switched back to the 2nd monitor by itself w/o having to go though control panel display settings and then when I turned the TV back on it would shut off the 2nd monitor and go back to the TV again without having to switch the screens in control panel.

In the screen 3rd picture on the far right to be color and NOT be greyed out.

Sorry forgot to post that. Heres the link to my card ATI Radeon
