Here's my questions...If I go and set the contrast per the contrast setting defined on the Spears & Munsil disc, I get a different contrast setting than what is required to satisfy he dynamic range high tests. So, I'm a bit confused as to whether I should take the readings from the contrast test or the dynamic range high test. Any info would be appreciated!
I have the Sharp LC-46LE821 Quattron HDTV.
Over a period of time, I began to notice that the most significant performance gains were through calibration of Clipping.
And the only way to do that was to use CMS.
Sharp's CMS, on this Quattron, as anyone will tell you, is non-linear. One stepped value negative or positive has the effect of a completely - most times - seemingly random occurrence of what you would expect. It cannot be reliably predicted.
The Clipping aspect undisguised Sharp's CMS very effectively and it allowed me to produce reference Green clipping, near reference Red clipping and above average Blue clipping. White clipping cannot be resolved, but I know why (and is not really essential).
The resulting clipping calibration resolved the Green delta E 94 errors completely and allowed for incredibly detailed and accurate tonal ranges in RGB far outside any calibration that has so far been posted for this panel. Because of Red and Green accuracy, the Quattron Yellow pixel was affected as well (although by how much is unknown), increasing Yellow's tonal accuracy to at least the level of the Red channel.
I cannot recommened Spears & Munsil's Blu-ray calibration disc enough.
In PC mode with this calibration, Sharp's 46LE821 is truly astounding in colour accuracy, colour tonal detail and just eye-popping realism.
Don't believe me?
See this thread p49: calibration
The most incredible thing I just watched 15 minutes ago was "Stephen Fry's In America". It is heavily reliant on complete control of Red, Blue and Yellow. Green is reference perfect on the Quattron panel and it shows.
Before this Clipping calibration, it just didn't work at all.
If there is a LCD/LED panel that can beat that experience, I would really like to know.
