G5 Mac with display problems

I bought a Power Mac G5 2.0GHz dual processor (M9032LL/A, A1047) off craigslist for $60. I also have an A1081 20" Apple display. The video card on the G5 has 2 ports: an ADC at port 1 and a dvi-i on port 2. The monitor has a dvi connector.

When I connect the monitor on the dvi (port 2) and power the computer on, nothing displays on the monitor.

I've never used either of these devices before, but the computer boots into target mode when connected by firewire to my macbook pro and I can take screenshots and view them in target mode.

I do not know if a monitor needs to be connected to the adc on port 1 for a SECOND monitor to work at port 2, but I only have the one monitor that connects to port 2.

Stupid question: is display connected to power supply? I can't see it on picture, and its status LED is off.

If ACD is working OK, computer boots and you can take screenshots (as you've described) – graphics card it's shot – at least its DVI port.
 
It's powered on

The monitor has a cable which has firewire and usb, both of which are plugged into the mac, and a power cord that goes into an adapter which goes to the power outlet.

The monitor power LED is on.

When I power on the G5 I hear the boot noise. If I press shift + command + 3 on the G5, I hear the camera shutter and I can take several pictures of the desktop (although I can't see what pictures I'm taking in real-time).

When I connect the G5 to my Macbook Pro via firewire, I can boot the G5 and hold the "T" key on the keyboard (of the G5). The G5 appears on my Macbook pro desktop as "Untitled" because it boots in Target Mode. In Target mode, I can see desktop screenshots from the G5.

I would try connecting the monitor to both ports on the graphics card before declaring anything shot.

I would also try reseating the graphics card - they do come lose quite often. Secondly, stupid question, but are you sure the graphics card is original to the PC? Sometimes craigslist sellers will take out the original card and stick an incompatible one in.

Nothing short of a $25 adapter is going to connect that display to the ADC port on that video card.

I second the motion that the video card is faulty.

Okay, I've tried reseating the card. I might have to buy an adapter like Intell said to try connecting it to the ADC port. As far as original card is concerned, I'm not sure.

That's the ATI Radeon 9600 Pro card. It's the second slowest card offered on the G5 lineup. You can get another one of those or something faster. You can even cheap out and get the slowest card, the GeForce 5200FX.
 
What's the fastest?

So you'd suggest getting another card. This other thread has some recommendations. https://forums.macrumors.com/threads/1234320/

No. DVI alone should work. I have a radeon 9800xt and just use the DVI for my monitor.
 
You all are helpful!

First time posting a thread and I really love the support.
@Ickystay, that's what I was wondering; glad you pointed that out about the display working from either port, alone.
@ybz90 the keyboard came with the craigslist computer. It says macally model no: KEL-USBKB.
@misterkeeks I wonder if I should try getting a hdmi adapter to test the video card with my tv or have a friend with a monitor try theirs because I still don't know if it's the card or the monitor (before I purchase a video card). But if I do get the video card, I'll make sure it's AGP. Checking ebay now.
 
video card purchased

I ordered an "Apple Power Mac G5 NVIDIA GeForce 6800 Ultra 256MB AGP Video Graphics Card".
 
Don't know how

Can't you plug the monitor to the macbook pro to test that it is working? that would be my first step...

The thought had occurred to me but I don't know how. The monitor has a cable with dvi/usb/firewire and the macbook pro has ethernet/firewire/thunderbolt/2 usbs/sd memory/line in/headphone.

there are cheap adapters available to connect thunderbolt/mini-displayport to DVI... I would start from the cheapest solution to the most expensive, and a new graphics card is considerably more expensive than the adapter...

Too late.
 
Too late, indeed.

Right, MisterKeeks. I already purchased a videocard. Waiting for it to arrive. (fingers crossed)
