Seriously, who doesn't have a dual link graphics card these days? Even the 7300LE and X1300 pro had dual link connectors.
to what extent? All LCD monitors and TVs lag compared to CRTs. I've never found it an issue.

Add to this the concious, subconscious barrier, which occurs at approximately 26Hz, and I seriously doubt anyone actually has experienced input-lag.
Unless I am mistaken, and the "terrible" input lag is in the order of 40ms.

Okay so yes... 30-40 ms would be detectable, at a sub concious level anyway.
And even that definition is not quite right... it doesn't "refresh"... it simply can't detect, zip, no see, anything that occurs at less than 32 ms. It is equivelent to a refresh rate of 31Hz. The eye doesn't sample like a camera does.
So if anything changes in that period, i.e. if something changes in less than 32 ms, the eye will detect that change. What you need to look at to detect lag is the sub-concious, concious barrier, which I said was about 24Hz, i.e. if anything is visiable for over 41 ms then the mind is aware of it.
So yes, if the Dell had input lag of over 100 ms when it was first released, then I would class that as "terriable input lag", but right now I think it is sitting at around 50 ms, which is just on the threshold, i.e. the mind can easily compensate. Take a movie for example, it refreshes at 21 Hz (47 ms) on average, and very few people can detect it. The motion still appears fluid. In fact, I've noticed people still think a picture looks fluid at 15 Hz (67 ms), depending the content.

This new review of the HP LP2475w makes it worth considering
