Yep - most of us with the older sets like my E6 also deploy some white-balance IRE adjustments to help with the near blacks. They do help and my set is better in this regard than before the edits. The newer models are still better out of the box than mine but at least we do have a way to mitigate it somewhat.Hi, everybody!
This is my first post on this forum. I've been following it for years. I appreciate the forum a lot! I have found a lot of good advice.
I can confirm that of the 2020 models, at least the B9S suffers from poor near black detail. This was obvious as soon as I looked at the slides I scanned. The scan job has been done with care and a calibrated display was used, so I know exactly what dark details should look like. The LG B9 cannot display them with preset settings.
If you change the gamma to 1.9, the darkest tones will be greatly improved, but the overall contrast effect of the image will be reduced too much.
I get moderately good results with these settings:
oled light = 40 (dim room), higher value in bright room
contrast = 85
brightness = 52
gamma = 2.2
white balance | 22 points ire | ire = 2.5 / adjusting luminance = 10
white balance | 22 points ire | ire = 5 / adjusting luminance = 7
white balance | 22 points ire | ire = 7.5 / adjusting luminance = 4
white balance | 22 points ire | ire = 10 / adjusting luminance = 1
These need to be further adjusted as experience is gained.
I think the C9 would be better in this regard. I conclude this from the following information, among others:
Cnet reviews say that the brightness of the B9 model had to be increased to 52 (“to help with shadow detail”), while a value of 50 was enough for the C9 model.
And the site LG C9 vs B9 OLED TVs : What's the Difference? - Refresh Robot says:
”Compared to the C9’s 018 chipset, the B9 chipset has:
-Near-black quantization. Color quantization is the process of the reduction of color used in an image, which is essential for displaying images accurately when only a limited number of colors can be displayed.
-Lack of bit depth, which causes more flashing artifacts and noise in the shadows and darker scenes. The B9 model hides these artifacts by darkening the near-black gamma, which can reduce the level of detail. You can calibrate this with SDR settings, but not in high dynamic range (HDR) or Dolby Vision.
Overall, the C9’s processing power allows for neater image upscaling, better near-black quantization, more precise shadow detail, and higher peak brightness compared to the B9 model.”
That was a quote from RefreshRobot. This mention explains many things: “The B9 model hides these artifacts by darkening the near-black gamma”.
Maybe it is precisely because of this that some have left the IRE settings unchanged due to the appearance of artifacts. At least the LG B9 and lower or older models hide artifacts by hiding dark details.
Enjoy your set!
