Thank you for your input. Are there any correction curves out there that I could have a go at? For instance anyone that has calibrated their Dell u2711s using a Spyder 3 AND a spectroradiometer, producing a correction for that setup (ignoring unit-to-unit variance)? Or 2nd best would be (I guess) anyone doing something similar for a Spyder 3 and any wide-gamut s-ips CCFL display, perhaps the Nec pa271w or the Apple 27"? Should the Spyder 3 correction curve ideally be 7-channel (as it is a 7-channel native sensor), or is it sufficient to do correction of the 3-channel default mix of those? regards k On Mon, Jun 20, 2011 at 11:18 PM, Rishi Sanyal <rishi.j.sanyal@xxxxxxxxx> wrote: > "But then those correction curves would only be strictly valid for a > given pair of measurement device and display.
