DVI-D dual link cables

Quick one.. I'm considering buying a cheap Dell refurbished 3007WFP-HC (if anyone has any advice re that, I'd be interested to hear too.. are they generally in good reliable working condition? this one only has a 30 day warranty), and the seller advises that he cannot guarantee that it will come with drivers and cables. I've just had a look on ebay to see what the deal is with dual link DVI-D cables and they seem cheap enough, but one thing got my attention.. the seller says:

"Supports resolutions of up to 1920 x 1080"

I know that DVI-D cables are digital and hence they don't show artifacts on the screen in the way analogue cables would (ghosting, etc) - they either work or they don't. Could cheap cables result in my 3007WFP not working at all with them? Has anyone experienced this, or will they generally be ok at 2560x1600?

If they're hit and miss, I'd be a bit concerned about buying a monitor without the official Dell cable... advice? :confused:
 
Yet another seller says "The DVD-D dual link configuration provides enough bandwidth for resolutions up to 2048 x 1536 and allows high speed digital transmission up to 9.9 Gbps"... also not high enough for the native 3007WFP-HC... :(
 
2048 x 1536 doesn't make sense for a DVI resolution spec. I think it is analog which a DVI-D cable doesn't support (it's pure digital).

If the vendor's picture shows you the end of the cable, you can compare it to http://www.datapro.net/techinfo/dvi_info.html and see if they're giving you the correct info or not.

The 1920 x 1080 is a single-link DVI resolution, not a dual-link resolution.

This non-sense reminds me of people selling USB 2.0 cables when in reality they are 1.1 cables.
 
Be careful with thinking that just because it is DVI-D that you won't experience ghosting. Ghosting is found on all LCD monitors, regardless of analog or digital connection.
 
The ONLY way to run the monitor at its native resolution of 2560x1600 is with a dual link dvi cable and a video card that supports dual link dvi. You can buy a dual link dvi cable anywhere that sells cables. The drivers are specific to your video card not the monitor.
