Trying to use PowerMac G4 with HD Cinema Display

I am trying to use a PowerMac G4 Digital Audio with an Apple HD Cinema Display (23-inch). I bought the Belkin connector so I could connect ADC to DVI. When I start up the Mac, I get the startup screen, gray with Apple logo and spinning startup ball, but then it goes dark. Any idea what the problem might be? Could it be a video card issue? Thanks!

I have little knowldedge on this but wasn't there a recent discussion on power issues in this configuration? Also try holding down teh shift key while starting up so it starts in Safe Mode. If that works it isn't a long-term solution but at least it would help narrow down the issue.

Japamac's really the authority on video cards for these old Macs - you can't do better.


If I were staying on the cheap, I think I'd go for the GeForce 4 - there's a 64 MB variety with ADC and DVI connexions and a 32 MB one with ADC and VGA (I think I'm right on that). The Radeon 9800 is definitely better, and the nVidia 6800 is better yet. It's the one I use (on Japamac's recommendation). Both have DVI connexions and VGA (which usually works - there are occasional anomalies - pay attention to the seller's comments).


I've had good luck with eBay video cards. I like the Apple ADC monitors,too, but they are better purchased locally - where you can see them work and inspect the stand: they don't ship worth a darn.

P.S. You might try Japamac's Radeon 9000. I just found one lurking in a dark corner, and plugged it in. Works pretty well, too. There are several varieties of them, too, with different port configurations, 64 or 128 MB, and prices from $25-75 on eBay.

I've ordered a 9000 Pro that will be here in a couple of days. Having a hard time finding an old Apple monitor that is not beat to crap and is inexpensive. Made a verbal deal for one on craigslist, good shape (supposedly) and cheap, but the guy backed out of two appointments... and I don't need that aggravation. I'm gonna keep looking, but is there any new monitor that work work well with the DA, 16:10, doesn't have to be big but it should be relatively inexpensive? Thanks!
