Adaptor: 23" cinema display to G4 monitor plug?

[eclipse]

How do I do it? I've got a 23" cinema with the glass edge from about 4 years ago, it has the one port with the pins (male) looking like

where-as my poor old G4 has the monitor port (female) like this...

I'm sorry I don't know the names of these guys, but there it is. Any ideas? (I'm hoping to buy a new G5 in about 6 months to a year).

Not sure from your description and ascii art but could it be that you need an ADC to DVI adaptor

And I doubt you'll be buying a new G5 at all

Oh the shame! You know me too well my wife gets the new machine, and I get her old G5. Buuuuuuuuuuhuuuuuuuuuuhuuuuuuuuu

This is my old G4 monitor port from 1999! So it's monitor port is a VGA 15 hole.

Now this is where it gets fun. A friend let us know some Mac floor stock was going cheap, and so we got a nice new aluminium monitor. I get Joy's old monitor. It has ONE cable, a DVI cable.

So now it seems there are adaptors but they are about $600 dollars because they have to have a power core and plug into a power socket etc etc. That's too much money because all of this is just to tide us over until we get Joy a new G5 later in the year and I get her old one, which married her old 23 inch monitor perfectly.

But.... then we realised that Joy's NEW aluminium trendy 23 inch monitor had it's own power supply, and that the DVI cable was just data! That means we can now look for a cheaper little VGA to DVI monitor adaptor from Dick Smith or somewhere. Cool hey? And I get to borrow Joy's trendy new aluminium monitor for a while... until she gets a new G5.

This port is one of these....

Any ideas what a Mac adaptor might be called?

The funny thing is we got an adaptor in the monitor box, which is exactly opposite to what we required. It has the female version of the VGA port (not the 15 pins but the 15 holes) and the male version of the DVI port above with 2 sets of 9 pins each! What on earth do people use THAT adaptor for?

The mac adaptor we already had (useless) from the box was like this Dick Smith thing but white and a bit shinier (of course).

So it must be for taking a DVI signal from a modern computer and translating into a VGA signal for an old monitor. I want to do exactly the opposite AND am also concerned that it simply might not be able to scale up to 23 inch pixels.

* Connectors: DVI-A Male to HDB15 female

The Polycarb (plastic) Apple Displays use a connector called ADC (Apple Display connector. It is similar to, but distinct from DVI. In most cases you can connect an ADC to a DVI port with a DVIvalatior, but not the CRT with ADC as is needs an analog signal, and the DVIvalator only converts the digital signal. As for your VGA connector, you are at the bottom of the totem pole, everything can be converted to you, but you cannot connect to any of the other display connections. ADC can be downgraded to both DVI and VGA, and DVI can be downgraded to VGA and converted to ADC.

Your best bet would be to look on ebay for a newer Mac Video Card with DVI.

Sorry,

Oh..... ok. It's not looking good then?

Woah, hang on a bit. I'm thinking of not using the Plastic monitor but the aluminium one with the multi-junction box connections. So the box will supply the power, and .... maybe... I can get a signal translator?

These guys ALMOST had the right one... but the DVI was male not female.

While it can be done, nothing will work. As the VGA port puts out an analog signal, and the Apple Display wants a Digital signal.

You can get a Mac Video Card with ADC and or DVI for about $25 (USD) on eBay.

What kind of G4 do you have? And more specifically what kind of video card does it have? Is it the ATI Rage 16 mb card? Strangely I have this card in both a cube and a powermac G4 and while the cube can't drive my 21" widescreen Eizo monitor the powermac can.

Its.... it's.... so old, I'm so ashaaaaaaaaammmmmeeeed.

BTW — If the cards are that cheap, I'm interested in a new card. If someone can help me get something compatible with the NEW Aluminium monitor and this old beast of a G4, I'd be ecstatic.

Also, I'm in Australia so I don't know if that affects any specs. Cheers.

TEG - what is a "DVIvalatior" ? I googled it but found no results.

Thanks
