Hi. My ultimate goal is to be able to play videos from my computer on my 40 in LCD TV. I was going to buy a DVI to HDMI adapter, and a 20ft HDMI cable (my TV is pretty far away, and can not be seen when sitting at the comp) and a 20ft audio 'Y' cable, but I realized I would just be adding a second monitor. I don't want a second monitor. I don't want to be able to drag windows over to the TV all the time, because I can't even see it from where I am sitting. Basically, I want to have the TV as a second monitor, but only when I am viewing videos on my computer. When I am surfing the internet, typing a document, playing a game, or using photoshop, I do not want a second monitor. If I don't check the box that says "extend my desktop onto this monitor" the screen is blank. Is there a way to switch between one or the other monitor at a time, or can the TV duplicate what is on my monitor, cause that would be choice. I remember on Dell laptops (which I used to support) there was a hotkey for switching between your screen, a second screen, and both screens with the same thing on it. I would prefer that a video signal is only being sent to the TV when I have that input selected, in other words, I don't want to clone the screen when I am typing a document, even if the TV is recieving from the cable box, and not from my computer.
