Anton Meleshkevich February 3, 2019 Share February 3, 2019 Are everybody ok with grading using a monitor with 700-800:1 ANSI contrast? This is pretty usual contrast ratio (when set to 100 nit) on so called grading monitors like NEC, BenQ, etc. I mean, for grading you should have at least 2000:1 ratio. Black at 0,05 nit or lower. But I found, for some reason I'm more accurate in blacks when I work at monitors with 700-800 contrast ratio compared to 1150-1350:1. I know about angles, ips, OLED, environment lighting standards, etc. Just curious what you think about working with not 2000:1 ANSI contrast ratio displays. I'm talking about measured data. Not about data taken from specs of course. Link to comment Share on other sites More sharing options...
Andy Minuth February 3, 2019 Share February 3, 2019 Ansi contrast of a typical DCI projection is around 100:1 (that is the minimum tolerance). A lot of big projects have their main grade done in such an environment. But you can argue that an average picture level of 50% (ANSI checkerboard) is not that common. Typical images are darker, which increases the intra-frame contrast of a projection. 1 Link to comment Share on other sites More sharing options...
Anton Meleshkevich February 3, 2019 Author Share February 3, 2019 (edited) My fault. I mentioned ANSI contrast to exclude measurements of many TV panels where is impossible to turn off auto dimming even in service menu. ON OFF contrast can be about 3000:1 there because of auto dimming full screen black patch. I was talking about usual contact probes. So neighbor white squares can't affect that much to black squares as it happens with non-contact colourimeters. So I meant just a usual contrast ratio measurement. Saying about ANSI was just to make sure, we are not talking about auto dimming. Edited February 3, 2019 by Anton Meleshkevich Link to comment Share on other sites More sharing options...
Andy Minuth February 4, 2019 Share February 4, 2019 I see. I think the contrast depends on the conditions people will watch it in. Sequential contrast (without auto-dimming) in a real cinema is usually between 1000-2000:1. Having 2000:1 during mastering sounds reasonable. Some people at home have around 4000:1 on their TVs (OLED for SDR). During mastering one should try to at least match that. Having more is better in both cases.
