Just for the fun of it I ran some tests comparing 17^3 profiling and calibration, with a Quick Profile and calibration - all with the i1D3.

The 17^3 took 1 hour 20, and the QP 2 mins.

The results were rather interesting, with very little difference - both in the numbers and visually.
The display was a 'standard' LCD TV with acceptable RGB Separation, but does show what can be done with a very quick calibration process.

See: http://www.lightillusion.com/calibration_speed.html

Personally, on this display I normally use a 21^3 profile and calibration, as it takes just 2 hours 30, but it was an interesting comparison.

Hi Steve,
I was looking at the graphs on your link and it occurred to me that if your RGB seperation is that good to start with, why do a LUTs calibration? Isn't the main benefit of a LUTs calibration to correct for the non linearities?

Samsung 64F8500, Panasonic 65VT50, Oppo 95, Tivo Roamio for OTA, Dish VIP722, Marantz AV8801 preamp, Rotel Amps, Atlantic Tech 8200 speakers, Seaton Submersive HP, Calman 5, Chromapure, Accupel DVG-5000, i1Display3pro, i1pro2, eecolor colorbox.

Hi Jim,

That's a good question, and the simple answer is that while the display screen may have a 'linear' response to a change in input signal, very few in-built display colour management systems are themselves 'linear'.

This means the display's cms will introduce non-linear inaccuracies.

Unfortunately, this is all too common.

Also, the granularity of a 3D LUT is far greater across the full volumetric space than any display cms.
(Basically, in the example on the website page you have 17 point control over Red, Green, Blue, and Grey Scale, with the volumetric correction calculated between them - that is just no possible with basic display controls).
That will always produce a better final calibration.
