Dell UltraSharp 3007WFPT Monitor Need Power Cable and DVI

I just bought a used Dell UltraSharp 3007WFPT. It didn't come with a power cable or DVI cable. I know it needs a dual-link DVI cable to perform at the highest resolutions. I have a question about the power cable though. I pulled the power cable from my HP 20" monitor and plugged it into this monitor. It started up fine and then changed from color to color for the entire screen. Would it be all right to use this power cable or do I need a certain wattage to ensure the monitor's safety? Thanks.

If it's just a cable, and not also a powersupply, then you don't need anything special. The cables are all the same. But if it actually is a powersupply (some displays come with external PSU's), then you need to make sure that it can supply enough amperes for your display. But with modern displays the PSU is normally builtin, and you don't have external ones.

So I suspect that your used monitor is defective...

The monitor works fine, I just need to hook up DVI cables to it to make it display.

That doesn't sound as if it works fine to me.

I don't think that monitor is working perfectly. To me it looks as if some electrolytic capacitors or other electronic parts within the monitor are on the way out. Although you can replace things like that, you do need soldering skills and an electronic background to do that. Having it repaired by someone else won't be cheap though.

I figured out that my video card was nearing it's end. Both monitors wouldn't display yesterday morning so I hooked them up to a different computer. Display came right on and I tested everything. Please close question.
