The question is not the availability of a particular feature, but the possibility to use it. Hardware calibration offers the possibility to make corrections directly in the monitor controller and to adjust the internal LUT (look-up-table). This LUT offers a resolution of 14-16bit, in the newest models even 10-14bit per channel (RGB, 3D-LUT), which means that you have up to 16384 (14bit) supporting points for a correction instead of 256 (8bit) as you have in the video card, due to limitations of the OS. This can lead i.e. to massive tearing in gradients. The other thing is: while calibrating your device to a specific condition (i.e. whitepoint D50), you have to "deform" the original gamut to fit the desired target. 8bit-calibration will limit the range for modification and corrections and will definitely shrink the gamut to nearly 2/3 of the original. Also the backlight is often not optimized for D50 and therefore print-related tasks, therefore you will lose much of the gamut to the deformation towards D50. This is mainly the reason why LCD-TVs cannot be used for high-quality softproofing. Their backlight is optimized to video standards, not to print standards. So, the only way to preserve most of the technical possible gamut offered by the panel is to perform a hardware calibration.

Coated paper have bigger gamut in cyans than typical sRGB display while most wide gamut monitors cover coated paper gamut. Which criteria make Dell, HP and NEC widegamut displays not suitable for softproofing?? 2011/10/13 Jens Heermann <argyllcms@xxxxxxxxxxxxxxx> Hello list, please be advised, that "wide gamut" is not everything. For high-end-softproofing only monitors, that can be hardware-calibrated (direct access to the internal LUT of the monitor) can be recommended. Therefore I would exclude those Dell and HP models, as well as all Apple Cinema Display. They may feature a wide gamut, but it will shrink significantly when these models will be calibrated via a "software-calibration", which only offers 8bit resolution for grey steps, due to fact, that the corresponding curves will be stored in the graphics card and that the correction will also be done in the ICC profile. Therefore the wide gamut of those displays is merely a marketing argument but not worth a lot in the reality. As a developer of a high quality softproofing solution and consultant in the colormanagement field we only recommend the EIZO ColorEdge-series, the NEC SpectraView (Reference)-series and/or the QUATO IntelliProof-series to our customers. A good guideline for the "right" monitor are the criteria of the "Fogra Softproof Pre-Cert". Only monitors which can fulfill the criteria of the category "A" are suitable for softproofing.

I'm using colorimeter on many models of displays and it will be very useful have ccxm matrix for every wide gamut display available on market. Let's try together make complete list of wide gamut display models. Try to begin: 1. Dell UltraSharp U2410 2. NEC 2490Wuxi2 and NEC 2690Wuxi2 3. HP LP2475w Sorry for my english.
