The better meters will have comparatively little difference. On the lower cost meters, the difference can be significant (several 10s of percents...to the point that the reading is worthless). If you measure the screen full-white and then mask it down so only the sensor area is exposed and your reading goes down (and it will)...it is the lower reading that is the more accurate one.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 07-31-2013 02:53 PM                     Thanks, I will test it next time I'm doing it.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 08-06-2013 01:00 PM                     Looks like I've got a good one! The difference with my colour meter is 0.4fL and no difference in xy coordinates. 2.8%  |  IP: Logged Tom Bert Expert Film Handler Posts: 134 From: Belgium Registered: Apr 2010 posted 08-08-2013 07:59 AM                     FYI: more information on the 'value' of all those contrast specs. http://www.youtube.com/watch?v=Y5_1UwySrmQ  |  IP: Logged
