Beovision 8 40 - How to adjust light sensor, white balance and get rid of the soap opera effect.

This one suddenly appeared a few hours later. 

I typed out a long reply and it was lost. 

 

Once I get a coloromieter I will adjust probably for gamma and greyscale and post up my settings. 

 

Can we not attach images? It said it was posting and then.....nothing.

Sometimes I have that problem— I am never sure whether it’s the App, my WiFi, my Internet connection, or Keith’s sever.

At one time Keith made comment (I am paraphrasing) something like ... the server is slow because of batch processing ...

So I always do a copy all before I post

And if I think the server may be sleeping I do a small post first

Oh OK. 

 

What I said was…

 

I haven’t actually changed that much now. 

Once I had changed the Picture Offsets I actually put everything else back to where it was originally, with the exception of leaving Film Mode to Off. 

And then made some smaller adjustments. 

 

I now have the following…

 

Picture Offsets….

 

The number is the lowest it will drop to when the room goes dark. 

 

Brightness 29. 

This means even at the lowest setting I can still see the difference between 0ire (absolute black) and 1ire (smidge above black). 

Dropping to 28 means black bars get no blacker and 1ire is no longer seen, so too dark. 

Upping to 30 I can’t see the black bars getting any lighter, so might end up here. 

 

Colour 28

This actually reduces the colour a bit, but you need to when the contrast is reduced, otherwise everything starts to look oversaturated. 

 

Contrast 63

This is the highest it will go. 

This is like having the contrast set to 3 clicks left of middle with the light sensor off. 

This now means that when I have the contrast set to around 90% on the main user setting, it is plenty bright enough during the day and how I like it in a dark room. 

It could actually be a bit brighter at night, but then a bit too bright during the day, so 90% is a good position to leave it at just there is no fiddling. 

 

Since doing all this I have found the picture is much better all round. 

I do still think there is a bit too much green in the lower ire ranges, and too much blue in the very highest ire range. 

 

I have upped the Red and Blue Offset in White Balance by 3 clicks. 

This has got rid of most of the green push down low and also lowered the gamma slightly, which gives less crushing of dark detail. 

I have dropped the Red, Green and Blue Gain slightly too, this has raised the gamma slightly in the upper range which makes it look less washed out. 

 

That is it for now. I would like to get a coloromiter on it and measure the white balance at least at 30ire and 80 ire (which is the pattern that the TV outputs) and check the gamma. I like a gamma of 2.4 normally, but if the display struggles with dark detail a bit then 2.2 in the lower region is good with 2.4 up top. My guess is the Beovisions tend to be more like 2.4 at the bottom and 2.2 or even 2.0 at the top. 

 

 

 

Anyway, I when I get to borrow one I will set it properly and post my results. 

🤒

I still think it is better with the auto sensor off. 

It doesn't actually seem to dim the backlight, it just adjust contrast, colour and brightness. 

So you lose overall luminance but don't gain better blacks, which is sort of the point imho. 

 

Anyway, like it a lot. I will be honest, I bought it as a TV to sit on the floor and use to listen to the radio and Tidal, with the ability to watch Sky News and RT etc. occasionally. But we have ended up using the front room more and more with it in. So had to raise it up, sitting on some old speaker stands at the moment, and can't find a unit to fit it on that works in that room. 

So decided to move it on as I think I have done a deal on a Beovision 11 which will work much better aesthetically in the corner of the room. 

Have it advertised on gumtree silly cheap. 

 

But thought I would post some images of it with my settings as I know people like pics!! 

 

And one of the room....

Nice !

I would have loved to have seen some before and after shots of the same frame in various movies / shows.

I am not sure eyes would see a difference 🙁

Mind you some of your movie video shots look terrific !!!

Deleted this post as images were not refreshing. 

 

See below....

This is my set now properly calibrated.

I have now turned the light sensor back on.

This was after realising the ADAPTIVE BACKLIGHT settings also control the range the back light works in, well I knew that, but what I didn't know and what I didn't try was dropping it down to 0 on LOW. Dropping it lower from the default 113 actually keeps the contrast higher, so it doesn't get that 'ooh its too dark' looking image that Beovisions can tend to do.

So,  the contrast offeset is not at max, 63, and the adaptive backlight is set at 0-255 rather than 113-373 it was by default, so we still have the same range on offer, but even in a darkened room I now have an image that is wonderful, and in my room today with the light coming in it was plenty bright enough. Closing the blinds I could see it was dimmer after 30 seconds or so, but it was subtle and that is what you want. 

 

I guess these setting will apply across the range, I have gone from thinking this set is good but old and shows it, to genuinely being blown away but what it can do. I dragged my OLED in the room to compare and they are so similar now which is amazing really. The difference in darker areas and skin tones and just the overall performance between when I got this and now is stunning. 

Anyway, I saw so many posts saying "My TV is too dark" and "The colours don't look right" that I thought I would post this thread. Hopefully it will help some of you and not bore you all to death? Haha

 

Anyway, my settings...
