What is causing this variation? AFAIK contrast ratio is just measuring the difference relative from darkest black to brightest white right? So if the BLB is bad, or you measure a high black point, the contrast ratio will be bad anyway right?
Is this more of a QC problem manifesting as bad contrast ratio? Or is there a difference with the actual panel?
