Re: [Avid-L2] LG OLED C9 number of internal LUTs for calibration?

Hi there

 

Yes that's right a new custom preset -  It's not in front of me but If you say setup the preset called Technicolor it will add one called Technicolor custom

 

Only the latest AJA things do the HDMI trigger I think.

 

Yes a second HDR preset

 

I think you have it correct.. We found some complication with Full range and Video just to get your head around.

 

In SDR the monitor is very accurate, generally people have said 55'' better than 65'' for uniformity across the panel.

 

There is also auto dimming on the TV which kicks in after some seconds on a still image. So this can be annoying when actually using in an edit/grade environment. You can switch this off but you need a special remote that gets into the engineering menues.. they are cheap on Ebay/amazon

 

Also we have found when they do an auto software update then sometimes the customs get wiped so best switch it off

 

We use the Calman software as well ..

Does this mean that after running the Calibration Software there will be in essence a new custom preset in the picture control menu?  I have the aja box that will trigger HDR mode in the monitor.  I would assume any professional running the Calman software would have that ability as well.

I'm no monitor tech but I've run the Sony white balance software on my PVM-2541.  I would think there would be a need to  calibrate SDR and HDR on the LG OLED, or any monitor for that matter.  Assuming the Calibration Tech has the necessary hardware/software to trigger the LG into HDR would the Calman Software create a second custom preset for HDR.  Is that how one would switch the monitor for HDR vs. SDR? 

After proper calibration by a professional then I would use my Aja Hi5 4K plus and to trigger HDR mode over HDMI and I would choose the Calman HDR custom preset in the picture menu controls.  Then for SDR I'd go to a different HDMI input that comes straight out of my DNxIO and choose the Calman SDR custom preset.  IIRC the LGs will remember which preset was selected for a given input so perhaps once I've done this once then just switching HDMI inputs will also switch the LG into the proper custom preset for a particular input.

I had thought the Calman software talked to  a LUT chip under the hood I didn't realized it created a new custom preset in the menu.  Come to think of it the Sony White balance software uses one of the user settings to store it's adjustments so sounds like LG is working similar.  Or am I misunderstanding what you mean by "custom setting?"

You can calibrate settings in the C( so you only need to use one HDMI input.. In fact I think the input is irrelevant. When you set up using calman the software creates a custom setting and you can have more than one.. HDR is a bit more involved because you have to be ableto put the TV in HDR mode so I think something that generates the Info in the HDMI stream.. AJA does this..

It is my understanding that as of 2017 the LG OLED TVs have the ability to store a calibration LUT directly from the Calman Calibration software.  How many LUTs can be stored?  Is it a LUT per HDMI input?

 

I want to know if the monitors can be calibrated for both SDR and HDR?  Would I need to dedicate one HDMI input for SDR and one for HDR?  I'm assuming that for proper Calibration it needs to be done separately for HDR and SDR hence does the monitor have the ability to have Calman software program two different internal LUTs or inputs.
