I've got a brand new 20" 2.66 Ghz iMac and I want to connect it to my CRT TV in a dual-screen kinda way. I've been researching and I've read that the mini-dvi to video adapter (http://store.apple.com/us/product/M9319G/A?mco=MTIyNjQyOA#overview) will allow me to connect to my TV, but what I don't know is if it will act like a dual-screen when it does. Does anyone know? If it doesn't, is there a type of adapter that will allow me to do what I want? Many thanks.
 
I have an adapter to my 20in Viewsonic LCD. When you say dual screen do you mean that both will show the same picture or you will have two screens with different windows on them? I am running Leopard and I run ichat on my Viewsonic and am typing this on my main screen(imac). I really like having two screens and it is really helpful keeping my screen uncluttered without having to switch to a different space all the time to use different apps. Hope this helps!
 
Im pretty sure that one won't work. You need to use the mini dvi to vga adapter and a second monitor. Do a search for it on the apple website. I'm using my iPhone and I can't copy and paste the link.

Cheers.

Edit: Just to be clear, if you want to extend your desktop, and not simply mirror it, you will need the mini DVI to VGA adapter (or the mini DVI to DVI adapter) and a monitor. The one you link to is fine for mirroring onto a tv or projector.
 
Can't really answer that one. In theory, you would think it would work as a way to extend your MacBook display to the TV, however the TV's resolution will be much lower then the MacBook's, so it might force it into Mirror mode, only.

I take it your CRT TV has S-Video and Composite RCA inputs, only?
 
I'm looking to extend my desktop, and yes it only has those two inputs. I've seen the sort of hook-up I'm aiming for with Windows PCs and CRT TVs, but never with a mac.
 
I have one of those, and I am only able to use it in mirror mode. if your looking to have dual screens I would honestly buy a nice LCD monitor and get a mini DVI to VGA adapter or mini DVI to DVI adapter depending on what connection your monitor will have. I just bought a 40inch Sony LCD and it has a PC VGA input on it...and man, what a difference.....


Hooking it up through S-Video cables will yield a slightly blurry picture..not to mention it won't let you do dual screens just mirror..I wouldn't recommend it if your going to use it as a 2nd monitor....I would only recommend it if you were going to use it to watch movies on your TV. However if your looking for a dual screen setup.........LCD Monitor is the way to go.
