![]() ![]() ![]() ![]() Using the traditional method, you will have a lot of negative values for Z (of XYZ coordinates) as you can see in the picture below, red is out of the visible spectrum it has negative values, the math has been improved with FCVM.įCVM will help to reduce these errors and provide more accurate meter profiling.įCVM is the default meter profiling method in ColourSpace it will measure three times the four patches (WRGB) to calculate the correction matrix. WRGB OLED (LG consumer) or this LG JOLED will need to use the new meter profiling method called in ColourSpace as FCVM (Four Colour Volumetric Matching) It will require advanced meter profiling method for example, LightSpace is using (like other software) the standard meter profiling method (based on NIST.FCCM). It looks like LG doesn't like FULL RANGE RGB 10-bit signaling from Terranex SDI->HDMI 6G, even using HDFury at the output to LG to send custom RGB AVI, it didn't work, signal reported as 422, while it was RGB.ĭirect HDMI connection from BMD Mini Monitor 4K can send RGB 10/12 bit, looking the LG panel, but it will degrade RGB Separation.Īfter that test, I believe this monitor is working correctly with 422 input, and some internal conversions to re-convert RGB input to YCbCr are destroying the RGB Separation.Īt this point, I can't recommend RGB input and FULL RANGE for full-range workflow.įor users with high-end meters, who are usually saving the meter correction tables to the colorimeter's memory slots, it's not recommended to use that meter profiling method. We used the new BMD MicroConverter Micro Converter BiDirectional SDI/HDMI 12G remember that this box does not support HDCP however, they are available solutions to remove HDCP protection. Using ColourSpace's RGB Separation and 3D xyY chart, and by taking multiple readings with -1, -2, -3 with Gray + Primary Ramb measurement, you can find out which Saturation setting will un-clip colors. Reducing the color luminance will unclip the colors. LG 32EP950 is clipping colors using the default settings it will require reducing the Saturation slider (which works as a global color luminance slider also). we used ColourSpace PRO due to high-end meters) (The calibration can be performed with ColourSpace LTE also using X-Rite instruments. He had a Klein K-10A colorimeter and a Colorimetry Research CR-250 with ColourSpace PRO. Since the BMD Bi-Converter can process a LUT only with YCbCr 4:2:2 signal, we had to adapt Resolve output/LG input settings for a VIDEO LEGAL calibration.įor the Patch Generation, ColourSpace was controlling Resolve iTPG (Video Levels), BMD Mini Monitor 4K was sending YCbCr 10bit via HDMI cable to BMD Bi-Converter, and another HDMI cable again to LG Monitor. We wanted to see which monitor settings were useful to use for pre-calibration and which controls were useless. I had no physical access to the monitor (I will buy one for me in the future), so the user was sending me the measurements I was asking for. I have helped a user to calibrate that monitor using ColourSpace, so I wanted to share the findings/results for other ColourSpace users of that monitor. ![]()
