Can I attach an external monitor to my iMac G5 (ALS) if the video card is dead?

I don't know for a fact that the video card is dead, but the screen on my iMac (PPC/ALS) 20" gradually started flaking out over several months and is now dead. Computer boots up fine and I'm looking at it through target mode right now. I want to keep using the computer if I can, so I am wondering if I can attach an external monitor through the DVI slot even if the video card is kaput. I'd like to get an opinion or two on this before I buy a used monitor and cable. Thanks!

My mistake: It isn't a DVI slot but a mini-VGA slot, not that it makes any difference as far as the original question goes. I'm beginning to suspect that a failed video card is going to keep me from using an external monitor. Can anyone confirm this for me?

You have found the answer. If the video chipset is OK but there is a fault in the internal display or its cabing, an external monitor will work. However, if the video chipset--which is farther "upstream" in the system--goes bad, the option of an external monitor is off the table.
