OK, my new i9200 arrived 2 days ago,
I'm lucky: my display is SEC5557 / Y4014 (checked trought Knoppix) (in dell shipping list F7116)
I opened the display, run win Xp and immediately I opened a new blocknotes... I was not completly satisfied: it's sparkles a bit on a white surface.... oh no.... I use the laptop on XL for 95% the time ... so I always look at white spreadsheet... my poor eyes...
I read a lot this forum (and others...) and I started trying changing settings.
I've obtained my best result usyng QuickGamma http://quickgamma.de/infoen.html
using tese settings:
In display settings:
CONTRAST: 200 (maximum value: yuo need to set this one for setting QuickGamma program)
Gamma red: 2.05
Gamma green: 1.95
Gamma blu: 1.85
No I'm really mutch satisfied!!!
For setting parametres I've used to compare same internet pages/photos on Latitude C800 (15'' 1400x1050) and Latitude D600 (14'' 1400x1050). At the end the colors are very similar even the white that in the i9200 is mutch brillant (and sparkling) than on the others 2 where white has like a little bit of yellow...
... I've seen Sony vaio in a computer shop... really amazing the quality... it seems looking a real paper sheet, but it is mutch more expansive!!!
