Wide Gamut Laptop Display – Dell

[Alan Cooke]

Hi there,  I have an aged but perfectly working Dell XPS 1645 Studio laptop  (Graphics card HD4670). The display is a Wide Gamut, RGB LED type).  I am using a Spyder 5 puck with DisplayCAL.

What I am hoping to get help with is which ‘Mode’ should I select given that these are my options:
1. LCD Generic

2. LCD CCFL

3. LCD CCFL Wide Gamut

4. LCD White LED

5. LCD RGB LED

6. LCD CCFL Type 2

Of these ‘5’ is the closest but does not allow for Wide Gamut.

Finally which ‘correction’ would be best?  I have ‘auto (none)’ selected.

Thanks

Alan

Where does DisplayCAL say that (“I do not allow widegamut in a RGBLED correction”)? Just use it.
Measurement device is not very good so if you get a “non visually white” maybe you can use Displaycal visual white point editor or get a better measurement device. If it is an IPS/WVA screen it should have a good contrast ~1000:1 so small corrections in white point can be done at GPU (DIsplayCAL calibration) without loosing too many unique grey levels & contrast.

Thank you.  I assumed that ‘5’ would not allow for the wider gamut.  I think there once was a wide gamut RGB LED option in a previous version of DsiplayCal but I might be mistaken.

Why is the Spyder 5 device not that good?

RGB LED can be only widegamut.

Spyders are not good reading dark patches, and 4/5 show poor inter instrument agreement. Bundled corrections like that list has low resolution and AFAIK it is not detailed by channel (just white, 10nm), also spectral sensivities stored in firmware can be far for accurate which gives you less accurate results specially for widegamuts.
There was some review in LuLa (photography, printing, color management forum, you may know about it), a comparison between a pair of units these devices, several models, agaisn a JETI spectrophotometer and NEC GB-LED. Not good for Spyder4/5 what it shows.
Spyders are de ugly girl/boy in the party. There must be one in every market so customers “have a choice”, but sensible choise was i1d3 and still si regarding new SpyderX.

Anyway, use option 5. White is visually white, you are done. If it does not look white… maybe greenish or pinkish => visual white point editor. If that way is OK, you are done without buying a new measurement device.
