I just entered the SammyGo community by installing some applications on my B651 and they are a big help. Just thought what else could I need and just remembered when doing calibration, I use the blue filter mode, but the tv has no other RGB modes like i.e. the Samsung LED my parents-in-law have... so I have to use the color filter card that came with my calibration disc. It's ok but I think it would be more accurate if I use an internal filter like the blue the tv already has.
Excuse my ignorance if this is technically impossible o very difficult, I have no idea of programmig/hacking.
