Without access to HW level LUT (best if it was a LUT matrix which cannot be so expensive to implement, because right now we have mobile displays with a BIG gamuts) … to calibrate mobile device displays is not an easy task. ![]() App was ColorTRUE and it was compatible with Munki Display too.ĪFAIK iOS uses “targeted color management” which IMHO is a way to say “we do not truly color manage so encode your content in a way we like”. Xrite tried this way: profile display with a mobile app + selected color aware apps with limited success (and I saltute their failure becasue we will be more close to a walled garden if they were successful). Since these display are not so predecible, it’s useful to create big XYZLUT profiles, which mean high number of patches… which usualy means a faster device like the more expensive i1DisplayPro. With that profile you could set it as displayprofile when color mamagement with custom profiles became avaliable to these devices (AFAIK there is no support yet)… or convert sRGB/P3/AdobeRGB images to that profile so when rendered in a non color managed enviroment in Android for example, they render color as they should be since these images are now en coded in device RGB colorspace (this works right now on Android but it means to reencode your content to THAT device). If that mobile device has a web browser without color management you can use Displa圜AL remote measurement for this task. What you can do is to profile the display of that mobile device, I mean to capture in a ICM file how does this display behave. AFAIK there is no portable ARM device with such features. In order to “calibrate” you’ll need acces to some kind of LUT (whitepoint & greyscale) or LUT-matrix/LUT3D (gamut emulation). If I invest $150+ in calibration device, I would expect to use it for providing professional calibration service locally, to cover the costs – and since mobile device calibration might become a thing, ability to calibrate Android & iOS devices would be a plus. Other programs like Basiccolor, i1Profiler or vendor software for HW calibration rely on Xrite SDK which are locked to whatever they allow to do ( = use i1DisplayPro or OEM versions). Munki limited software can be solvced using Displa圜AL because ArgyllCMS has unlock code for using Munki Display. Slower speed is HW related and cannot be solved. I think that Munki uses a slower cristal oscilator plus different firmware unlock code. This OEM version is supported by ArgyllCMS too. If you have one of these Cintiqs, so these devices are your “tablets”, you *really* want that OEM i1DisplayPro for Wacom even if it is more expensive. Price is almost the same of retail version. IDNK if it works with retail i1DisplayPro. ![]() These HW calibration works with a specific OEM version of i1DisplayPro for Wacom. If with “tablet” you meant some Wacom tablet+display like Cintiq series, “some” of these products have hardware calibration features. INDK even if ARM Windows tablets have GPU LUTs writable by user. ![]() If you meant ARM based tablets… you’ll need to compile for that platform, AFAIK there are no binary compiled distribution for ARM Windows RT and such. There are x86 and 圆4 ArgyllCMS Windows executables compiled for download. Tablets with wider gamuts may require that you do a little more research.ĭispla圜AL uses ArgyllCMS executables. Usually “sRGB-like” IPS LED displays need the standard Xrite’s “WLED” spectral correction (or a better one). If you want to use a colorimeter for x86 Windows tablets with “quality IPS displays” from diferent vendors (and maybe very different gamuts) you may want to read Displa圜AL documentation about spectral corrections. It’s a slowed down version of i1DisplayPro without support for hardware (=”internal”) calibration for some display manufacturers. Your cheapest choice if you are going to use Displa圜AL with current displays is Colormunki Display.
