Apple 20" display black screen

I have a 20" Apple Cinema display monitor I just hooked up to my G4. I  connected the monitor (using a DVI extracter II cable adapter). I started the computer and the monitor came on, showed the gray apple and spinning wheel for 10 seconds or so, then the screen goes black.

    Every once in a while my apple 30' display has a problem, the screen just goes black. To solve this issue I unplug the power cord 150w power adapter and plug it back in, this solves the issue and the display comes back on. Why does it do this?

I've read that aftermarket DVI cable adapters don't work well with this set-up. You might try the Apple DVI to ADC adapter. It's expensive but I see them on eBay or craigslist from time to time at less than half the normal $99 cost.

Yes, you can do this. Firewire is not necessary. That is for connecting your hard-drives should you want to do it through your display.

Apple cinema display has interference


Check your DVI cable for breaks. If that's not the problem, then you'll need a new IP board. Not sure of the part number for this monitor, it's printed on the circuit board. It starts with 820-XXXX or 620-XXXX in some cases.

Can I use an Apple M7649 Studio Display with a MacBook Pro


Do you have the black unibody Macbook Pro that was just released, or the silver model?

Since the display is DVI, it will directly hook up to the silver model. If you have the new model, you need a mini DVI to DVI adapter.

Studio display m7649 picture will not come up when connected to toshiba laptop


I am not sure how youve manage to connect these 2 items. You did not specify whic Portage you have, but even the most recent only has SXGA video port. The Apple cinema display connector is ADC. APPLE DISPLAY CONNECTOR. No computers on the planet have this port except for apple's. It's basically a modified DVI connector. In order for you to use this monitor with your computer, you would have to purchase a DVI to ADC connector , which is another APPLE only item and selld for $100 new. You would then have to purchase a SXGA to DVI adaptor...It sounds like a costly endeavor, and with a connections your Portage's onboard video card , amynot even support the resolution for this monitor.


Hope this helps.
