Dell 3007FPW problems

So i picked up a second hand Dell 3007FPW recently and have gone about replacing the GFX card in my dads comp to power it. I installed a Radeon3850 512MB. It has two DVI Outputs.

My only experience with 30" displays are the apple ones, and from what ive seen, they connect to the computer with a Dual Head DVI cable. One DVI into the screen and then into both outputs on the card.

I was told i didnt need one and picked up a Single Dual DVI cable, which im running from the screen into one of the DVI's on the card.

Now, this screen was bought second hand, and havent really had a chnage to look at it yet, aside from powering it up at ridiculously low resolutions of my old PC and my macbook. When doing this, there was terrible ghosting on both, and continues to appear on my dads PC (although now at 2560x1600) with the new card.

My question: at i crazy, or do i need this special dual head lead which runs out of both DVI ports on the card to power the screen.

If so, where do i find one. I've looked everywhere. Dell dont sell them rertail, and neither do apple.

No you do not need a dual head cable, all you need is a dual-link dvi cable. These are easy to spot, look at the connector, are all the pins there [in the main body of pins] or are there some missing [around half]? Not that it really matters since your running the screen at 2560x1600, thus you have the cable you need. The screen will only opperate at 1280x800 if you do not have the right cable or compatible graphics card. The only screen that i know of that can use 2x dvi cables is an approx. 36" ibm professional display, i can't remember the size of it but this was back in the day that apple first released their 30". Sapphires new 50"? might also use a dual cable solution. Back to the ibm, back when it was released dual-link dvi was rare as all buggery, thus they implemented a dual dvi cable solution, that is 2x individual cables into one display to allow the screen to run at it's native res. However since apple control all their own hardware they released mac ready cards with dual-link dvi so that their screen could and could only run of a single connector. That is the way it has stayed on the 30", if you didn't have a dual-link dvi compatible cable and graphics card then you were limited to 1280x800. That is until the dell 3008 that had a much more intelegent tmds reciever, which allows higher resolutions up to 1920x1200 @ 60hz the limit of single-link dvi.

As for the ghosting problem, well that's certainly not being caused by the cable. Perhaps the ghosting was the reason they sold the screen? That said if they had a problem with it when they owned it they should have got dell to replace it under warranty. Then again they mighten have noticed it and you do. I personally own an apple and dell 30", haven't had any ghosting problems. I've also owned another of both in the past with out any problems, i've used several 30" apples at uni and a mate owns the 30" samsung and i haven't had any ghosting issues.

cheers

thanks for that info.

is there anyway to get the ghosting fixed, or would it mean i full new panel? i bought the screen for $600, so it would be worth fixed rather than returning.

When the screen is unplugged it runs the B.W.R.G.B test, and there doesent seem to be ghosting or lag between tones and colours.

Ghosting or lag is highly unlikely to be visible with the test tones, as you have no control over the speed of colour change, the colours it's changing to and when they change. The test tone is really only useful for picking out a dead pixel, some major back light bleeding or to check that the screen is working at all. As for what could be causing it, well that's really the million dollar question that i can't answer due to the many causes. The ips-panels that they use aren't as fast as tn's, the first first generation 3007's ran at a response time of 14ms, so it's possible that you can simply notice the higher response time. Then again it could be a dud panel, or some other component inside the screen might be faulty too. It's just too hard to say. Personally if your not happy with the screen, i'd be taking it back and getting a refund as fixing it could end up costing you a considerable amount, but it's your choice.

thanks for that. im sure its actually faulty. its ghosting and the burns are holding for well over a minute after leaving a window in place for only a few seconds.

Might pay to go into the settings and change the preset modes around a bit - specifically avoid the dynamic mode that does some wierd dithering stuff that looks like shit.

I don't remember the exact mode, but I tried it for about 10 seconds and hated it. It supposedly improves response time, but looks a bit blurrier on mine.
