Most of the time you will find me watching SDR content during the day, and HDR/DV content at night. When the sun goes down, I can get the room pretty much pitch, so that would make more sense that I found myself turning down the OLED LIGHT to 70 for HDR technicolor, and raising it to 70 for DV Cinema (User) - ( 50 still just looks too dim ). Those settings are basically intended for a darker viewing environment.
For SDR, I have the OLED LIGHT set to 49, which not surprisingly works well in a med bright to bright room.
You might ask why the OLED LIGHT is lower for SDR than for HDR/DV even though that's a daytime setting? The simple answer is that SDR/HDR/DV use different scales and the HDR/DV thresholds start at a higher luminance level.
So now I can see the confusion that I may have caused. Keep in mind that my settings are generally middle range, so I think that they look great under a variety of lighting conditions. For me, it's a "set-it-and-done" kind of approach - or a happy medium.
I’m currently working in a production grading suite in central London.
The reference grading monitor is an Eizo ColourEdge CG318. On the wall is a LG 65 C6 with an AJA Lut box.
These monitors are set to 90 nits for SDR. Nothing is going above that level.
What is going at the moment is I’m creating a new 3D LUT for the Eizo, then have to create and match the image on the LG.
HDR I agree with you sonoftumble. You have to set luminance levels to suit the viewing environment. We already know that the EOTF (gamma) isn’t right for HDR that’s why HDR10+ is on the way. Dolby Vision on these 2017 sets out of the box is based on an assumption that the light output of these sets is consistent. They are not, they vary from panel to panel. That’s why you have the ability with the right kit to upload a Dolby Vision config file to your particular Oled to set Dolby Vision up correctly. Trying to share someone else’s settings simply won’t work as Oled light of 50 may be correct on one set, it may be 70 on another or 40 on another.
If you are not either doing your own or a having a professional calibration done, set the Oled light to suit your eyes and environment.
Contrast is another matter. Some sets clip at 100, some don’t. If they clip then contrast must come down, usually 90 sorts it but on a set not clipping, then bringing contrast down kills dark detail. If it’s clipping then the greyscale controls don’t work and displace.
LG have done a great job on the 2017 sets. They can be set up brilliantly.
This 2016 B6 in front of me now looks stunning with a proper 3D LUT.
We are at the infancy stage with HDR and there’s a long way to go 10 years or so before we get to where we’re going. (Took 20 years to get rec 709 right).
Set the luminance of your tv to suit you and your environment. Saying that, watching in a bright room forget seeing shadow detail, you simply can’t on any set, you eye simply does not work with extreme bright and dark, it takes time to align.
You should not be watching a bright contrasty blown out image. That’s not what HDR is about. With the right setup HDR looks awesome on these 2017 LG’s
