[QUOTE="rohnfe, post: 1152375, member: 154942"] Your patterns as i saw are YUV right ? (so video levels 8 bit) the patterns from almost every calibration disc i know is 16-235 8 bit video levels (limited color range) so it should be the "same" as to my understanding. Sure i know what you mean but nevertheless BTB and WTW exists and there some movies showing Details in WTW otherwise i guess no one would ever try to prevent BTB and WTW to be clipped as far as i know this is why you want prevent to expand video levels to 0-255 cause BTB and WTW is clipped that way. as 16 is the new 0 and 235 is the new 255.... Both is still 8 bits (0-255) but 0-16 is never used in video levels other than to hide certain things on purpose but WTW is used sometimes .... at least this is what i have read and discussed about. I guess if you want to have the "best possible" picture you want to try to preserve BTB and WTW (as you will have it using a stand alone BD Player for example). And this is what seems to be difficult when using a HTPC and calibrating for video levels afterwards. I know that BTB will/should never be visible on a calibrated TV but still its there (for example if i turn up brightness to max)...other than WTW what might be visible sometimes. Please correct me if what i said is totally nonsense ;) Please don`t get me wrong i just try to learn more about this stuff and try to get the best possible setup...
