Okay thanks

my settings:

red gain 255

green gain 254

blue gain 243

what about red, green and blue offset do you also adjust them or what?

My settings:

Red gain 255

green gain 240

blue gain 255

My Offsets are

my settings:

090 Red

057 Green

100 Blue

These I raised quite a lot as the dark areas were too dark, got a sort of weird black crush with lots of green in them. 

This has a much nicer, smoother gamma across the ire range. 

The other think I adjusted in the scaler menu was the flesh tone, it is now on 10. 

My ADC asdjustments are...

Offsets...

Red 124

green 116

Blue 135

Gain 

Red 058

Green 054

Blue 057

Auto black level 000

video AGC 001

Clamp 001

PLL 001

Then on the main settings I have brightness on the middle, towards right, contrast about 5 clicks from centre and colour around 7-8 clicks from centre. 

Okay thank you. 

How do you know all these settings?

I'm not sure what you mean? How do I know what settings to adjust? 

I have just been playing with the settings, I don't have a colorimeter anymore to test to see how accurate it is as I sold mine a while back, but I have had the screen next to my ISF calibrated OLED to compare. 

I have been ISF'ing screens for years, started doing it with CRT projectors, then with Panny commercial plasmas, through to DiLA projectors and OLEDs. I have some source material I know well to know I am pretty close to accurate. 

I do have certain issues with this set which to me seems to be in the software that B&O have implemented. The main thing is the greyscale does not track accurately enough across the IRE range, you can adjust at 30ire and 80ire (which is like most TVs) but there is very obvious green push in the 3-10ire range, if you dial this out there is then far too much blue in the 20-50ire range. There seems to be no getting round this. 

There is also a lot of noise in the lower ire ranges too, which isn't helped by the higher gamma in this region, you can up the RGB offsets and raise the gamma slightly but there is still noise in the lower/darker parts of the image and the problem you have then is the controls are coarse and then the upper/brighter parts are too bright. Also, adjustments in one area have massive effects on other areas, as in the RGB luminance etc. 

I have spoken with a couple of ISF calibrators about B&O sets and they have mentioned this before, and without being able to adjust RGB gamma, luminance, saturation, brightness etc. etc. you are in B&Os hands. Someone I know had the same issues on a Beovision 11 fairly recently. 

You can see the strange colour pushes in different ire ranges when you have say some pasty looking white guy on screen at the same time as someone with a bit of a tan and a black guy, the white guy can look a little blue, the tanned guy can look pretty spot on and the black guy can look a bit green. Haha

If you then adjust the set so the white guy looks OK the other two look out. This can be easily seen next to a screen that is correctly ISF'd. 

It is a shame as the areas it gets right are wonderful, I just wish there was some more control to get the image spot on. 

I have a Samsung panel still from the same era and that copes far better. Maybe it is more to do with the ambient light sensor and the way it adjusts colour temperature as well as gamma and contrast that it is designed like this? 

Anyway, it is what it is. There are tweaks to be made, but it does struggle with dark scenes, and in more serious ways than the fact it can't do blacks very well, which as I said is a shame as the brighter scenes are superb. 

Okay but It sounds like you are very good in this stuff so I believe I have a better picture now I have also think the screen was too cold on my Beovision 10 and I have always wanted a more red/warm picture like 6500k instead of 9000k I think b&o use on their led tv

Adjusting the offset for RGB under the White Point Adjustments makes quite a bit of difference to this set in the middle ire areas, more so than many displays. 

Changing RGB values by 5 points can make a difference, trying upping red and green first and see what you think? If it is still a bit cool drop blue by 5 points. This does change the gamma too. 

I would say the gamma is too high in the 0-20ire range (image to dark) and then too low from 20-100ire (image a bit too light). Without having a 10 point control this is a compromise, you can raise the Offsets slightly to lower the gamma at the lower end, but it also lowers it more in the 20-60ire range too which it doesn't need. 

For me, very slight tweaks in the RGB offset and gain can get the image much better/warmer. Plus everything can be put back so no harm playing, not in this setting anyway. 

OK, so sorted out the backlight issue. 

Under the service menu-monitor-picture adjustment menu you have Picture Offsets. 

These adjust how the brightness, contrast and colour reacts to the light sensor. 

I now have contrast on 63, colour on 28 and brightness on 30. 

I may have to play about with them a bit more, but Light sensor is back on and it is now working far better for me. 

I should add, these settings are not live adjustments, in other words you have to adjust and then leave the service menu for them to take effect. Hence I didn't think they were doing anything originally. The fact it tells you the amount of light the sensor is....well.....sensing, in that menu should have given the game away. Anyway, sorted now and well chuffed.

Looking forward to see your complete configuration change, I hope you will share a consolidated list of you adjusted settings.

Could be interesting to measure the screen afterwards
