Up next is a calibration capture showing the original readings as taken by a Jeti Specbos 1211 spectrometer on an LG 55LX9500 LCD that has LED local dimming.
Following that is a calibration run using the C6 Tri-stimulus colorimeter and its built in calibration tables / offsets.
From the look of these two results, the C6 calibration tables did not work very well at all. The end result is nowhere close to the Jeti Spectrometer results. So where did the calibration tables go wrong? What happened here?
A third calibration run is then shown where the same C6 tri-stimulus colorimeter is directly profiled to the Jeti Spectro device on this LG display.
So just with two sample displays in my own home, I get results that are reasonably close and not so close at all. If one learns anything out of this, it should be that the idea of calibration tables appears to work sometimes, and then sometimes it does not work very well at all. The open question is then … without a device to double check its performance, exactly how does one know when it is functioning correctly? One or two more data points for the record. A Sony 46HX929 LED/LCD unit at a store I often do work for and a Samsung UN55D8000 LED/LCD unit too.
