After receiving lots of emails here are my settings after the ISF calibration: Contrast:25 Brightness:+8 Colour:-10 Tint:0 Sharpness:-1 ADV Colourset:hand Mpeg:low Dnr:low Ctin Dreff Note:These settings are used with a greyscale of 6500 K Why did i calibrated my screen? Well,I was one of those who was always playing with the settings in the menu.I felt that the blacklevel could be better and I found that the lightoutput of the screen could be lowered,this was sometimes too much for my eyes,too bright,too hard,etc. The ISF technician came and connected his laptop with ISF software too the reciever and put a spectra radiometer on the screen and started measuring. He noticed that the screen was a bit cranked up too high from the factory,around 9000 K,and that explaided,the high brightness,and colours etc. After correcting too ISF standards,that is 6500 K,and setting the colours in balance,I was wondering what the result looked like. Blacklevel increased,much more blacklevel detail,before the calibration I lowered the brightness too get more blacks but I lost details doing that. The colours are very natural,really beautiful. Increase of dept. Artifacts are as good as gone if there were any(depends on what source) And last but not least:The buzz of the screen lowered dramatically.Before it was near and sometimes over the irritating factor.Now its still there but i have to lean my ear to the screen to hear it. I have it calibrated since 2 months and I didn't change anything in the menu. I'm really happy with it now. After the calibration you'll see the screen's potential. I live in the Netherlands and there are more ppl with a 435 who have calibrated their screen and all are happy with it. The costs were 125 euro. I do not know what a calibration will do for other brands plasma screens,sofar I only have seen a calibrated 434 and my hde 435.The 435 has the edge because it has almost no reflection during daytime watching,and it has slighty more detail,but this is very subtle. Thumbs up! Please place any calibration experiances inhere!
