My flat screen dome imac is nearing the end of its life and I am wondering if there is a way to reuse of modify its 17" flat screen; is there a way to make some kind of modification so that I could hook it up to a mini?

thanks for any help or ideas

Probably not.

What's wrong with the iMac?

That what sucks about the iMacs. You're throwing away a perfectly good monitor when the computer dies...

I repeat, to my knowledge, no one has figured out how to hack a built in LCD from a laptop or iMac to use it as a display from another device.

Maybe if someone could get a hold of the schematics for the entire machine, and the schematics for a typical LCD, someone with an engineering degree could figure out how to do it, but I have yet to see it happen.

At least on the old iMac G3s, they used a standard VGA connector internally and could be used as an extra display without too much trouble. These LCDs do not have that connector in them. Just 5 wires...

Where did you have that instruction on how to use an old iMac G3 as an extra monitor?

Just take dang thing apart and you'll find the DB15 pin connector inside (the old-style mac video connector). The trick is how to power the monitor since you are not using the computer. If the computer still works, just power it up normally and let the other CPU drive the monitor.

This pic shows the VGA cable you would connect to the other CPU (using an extension cable M-F).


I don't think this works with the slot-loaders that have an external VGA out connector, unless there is another VGA connector inside you can tap into.

Strictly speaking, that is not a VGA connector, but an old-style Mac monitor plug, just FYI.

Pretty much every laptop and desktop with integrated LCD use standard LVDS signaling as the display connection; adapters for this are available. But unless you're buying 100,000 pieces at once, they're prohibitively expensive.

Again, what's wrong with the iMac?

ok I tried that awhile ago, and I could never get the moniter to work with another computer. I tried 3 different pc's, some older macs, some newer macs, and none of them would make the moniter fire up. The iMac still works, but i use it as a server now, but getting the moniter to sync with another computer would never work.

Is there a website that has more info on making it work?

Being a idiot when it comes to graphics cards, could this drive a LVDS monitor? It says "Enhanced TwinView dual-display architecture supporting any combination of notebook LCD, desktop VGA monitor, DVI display or TV set...Integrated dual LVDS Transmitter supporting LCD panels up to 2048x1536"

You are right, tooki. I should have clarified.

A VGA connector is an HD-15 sub-D connector, while the connector in the G3 iMacs is a DB-15 connector, also known as an (old style) Apple Monitor connector.

Well... it was a standard Apple connector until the B&W G3s came out (or were they used on beige G3s before that?).

No, you are correct. All beige Macs, including the G3, used the Apple connector. (Though by the G3 era, the clone makers had already shipped machines with both Apple and regular VGA connectors.)

Is it possible to connect the panel to a EPIA main board with LVDS connector?
