Well... tonight I had my 436 ISF calibrated and I was initially very surprised with the results. The 2 HDMI inputs (3 & 4), RGB input (1) and component input (2) have all been calibrated separately; the job took just over 3 hours. The biggest surprise was that the correct basic colour setting for HDMI is "0", not "-8" and certainly not "-12" The contrast is "34" but can go to "38" without causing any problems (blooming/crushing), brightness is "0", sharpness is "-8" and tint "0". Other adjustments were made to CYMK & RGB, which obviously affect the picture. I learned tonight that it is impossible to adjust your basic colour settings when watching sky for example, as the broadcast material varies drastically. Yes the colour seems high on outside broadcasts for example, where the camera has not been properly calibrated, however, as soon as it cuts back to the studio the picture looks correct and natural - Sky News etc. RGB is slightly different, contrast is "38", colour is "-2", brightness is "+2", sharpness is "-8" and tint is "0". In addition, changes were made to CYMK & RGB etc. Pro Adjust settings (global) are as follows: Pure Cinema - standard for everything except for HDMI, which is set to "ADV". The standard setting helps prevent interlacing artefacts on Sky (RGB - input 1) and is greyed out when watching PAL DVD's via HDMI. When watching NTSC DVD's the "ADV" setting stops judder 100% - no BS DNR: Off DRE: Off Black Level: On CTI: Off Gamma: 3 ACL: Off There seems little point in posting the other advanced colour settings, as other 436's and DVD players are going to be different to mine. Anyway, all looks pretty good to me and Gordon certainly knows his stuff for sure Thanks Gordon!!!! It's going to take me a while to get my head around the colour setting though.
