A second LCD display for my Imac

I have an Imac running OS X 10.2 and am looking into having a second monitor. I do voice over recording at a home studio and can't see my monitor from my small booth. Can I run a second monitor? I'd put it in my booth and use a wireless mouse so I could ride levels in Pro Tools LE while I record.
Is a second monitor doable. How should I proceed, and what connectivity would I need in the LCD I'd purchase.
I'd very much appreciate advice on this matter.

...it really depends on what version of iMac you have. older ones do not support mirroring, newer ones do. Can you tell us a little more about the iMac you are using (processor speed, case style/color, ... )

Thank you for taking the time

Thank you for taking the time.
I have a G4 iMmac purchased in January of 2003. It has a 1 gig processor and one gig of memory. I'm running OS X ver 10.2.8

Mirror officially, spanning with hack

AFAIK your iMac has a GeForce MX4 video card.

Your iMac officially supports video mirroring -- you can hook up a 2nd monitor but it will only display the same thing that's on your built-in monitor.

However, the video card supports spanning -- having a 2nd monitor with different content, which you can use to expand your desktop space. check out xlr8yourmac.com -- there's an article somewhere in that site's archives (use the search function), which in turn points to a page on doing a firmware or NVRAM/PRAM hack to get monitor spanning.

Good luck!

Keep in mind...

...that if you have any warranty left on your iMac, doing that hack will void it. That includes extended AppleCare.


Obsolescence is just a lack of imagination.
Visit my blog: davintosh.com -- it may not be up to date, and it may not be exciting, but you can say you've been there.

re: Keep in mind...

Apple need never know. The spanning hack is easily reversable, just reset NVRAM in OF.

My need is actually only for mirroring, so it looks like my solution is at hand. Thank you.
