LG HU80KA Review: A Smart Laser Projector for Home – Advanced Calibration

Color and CMS performance was again just ok. There are 3 setting options for color gamut (Auto, Wide, Extended) By default it is set to Auto which usually is the closest to REC.709.  If you take a look at the pre-calibration color gamut chart you will notice some of the colors look way off target and this is mainly because all of the colors stem from the white point which in this case is quite blue/purple. So, improving the white point with my white balance calibration made big improvements to all the colors.

Once that was done I chose Wide as my color gamut hoping it would help with the red under saturation. Sadly, it had little effect and there were still some lingering problems. Cyan was still running towards blue getting worse at the higher saturation points. Blue was still blowing past its REC.709 100% saturation point. Again, red had the opposite problem with its 100% saturation point just reaching the 80% mark. Through CMS calibration I was able to improve all of these errors a bit except for red still maxing out at 80% saturation and blue being over saturated at 100%.

Well there is really not much to say here as there are no CMS controls available in Standard mode. The improvements you do see in the before and after CMS charts come from 2 picture settings, color temp being set from Medium to Warm and color gamut being set from Wide to Auto. Without CMS controls post-calibration color gamut is not good with blue over saturated quite a bit, magenta over saturated and running towards blue. Cyan also running towards blue and red under saturated, running out of gas around the 85% mark.
