Guys, i've got some news! I found service menu. No idea if these values are from factory or previous ovener, but green driver is definetly overdone. I've made RDRV and BDRV to 100 and GDRV to 80. Now i've got proper colours and default RGB menu can be used for tempereture setting, not the colour fix.
I wonder what are the default values and what other menus do, maybe i need to alter there smth... 😀
Did you do this adjustments while displaying grey scale from black through grey bars dark to nearly white and last bar is white? This is easiest way.
Reasons for this grey scale bars used for adjustment:
1. Easier to see how overdone the brightness of overall.
2. Easier to get proper look that you can see all the greys linearly, not too pale or not too dark to tending one or other end.
3. Easier to spot any tint of color showing in the grey scale especially grey bars while hard to do this with just black or white or displaying color bars.
Standard way is reset the customer user settings to defaults, always! If brightess is too high, adjust down some.
If there is no way to do grey scale, instead display color bars and through the user setting, turn down color to zero, this will show grey scale for now. Important is choose a color bars *including* white and black in it.
Every TV or monitor I got ahold of were too much in brightness and compressed color look. This was to "upsell" to buyers and especially on CRT were hard on cathodes. Done correctly, the brightness and color corrected via grey scale method you will find settings will be much less than before and extend the CRT's cathodes life significantly.
Done correctly, you should able to see every details without blown out color, greyish or too dark overall, and details easier to understand, skin tone, and especially browns look good.
