In your post #1327 you asked if I had considered using Colorspace Auto instead of Native and Movie mode versus Standard mode. Based on your suggestion I went back and spent time recalibrating the TV using five different scenarios. Recalibrating meant going back and doing the basic visual calibrations (brightness, contrast, sharpness, etc.) as well as adjusting the White Balance using the colorimeter. Picture quality with each scenario was checked by watching scenes of BD Blade Runner and BD Harry Potter V.
Having written down the complete final settings for each of the five scenarios I then proceeded to calculate the average gamma and average deltaE for the five scenarios in rapid succession. The TV and i1 D3 had been on for hours. The five readings of the average gamma and average deltaE were taken in a period of approximately 20 minutes without moving the i1 D3. I tried to keep everything the same so that the results would be comparable. I used the same CalMAN 10 point grey scale test that is shown in the screen shot in your post #1336 above.
The measurements were taken with a new i1 Display 3 and CalMAN Tutorial software on my 55EH6030 in a dimly lit room.
The five scenarios and the calculated average gamma and average deltaE are as follows:
Standard Mode - Colorspace Auto - Blacklevel 16
Standard Mode - Colorspace Native
- Blacklevel 16
deltaE 2.09Movie Mode
- Colorspace Auto
- Blacklevel 20
Movie Mode - Colorspace Auto - Blacklevel 16
Movie Mode - Colorspace Native
- Blacklevel 16
Assuming my i1 D3 is properly calibrated the above results are interesting. Using Movie Mode allows one to dramatically lower the deltaE by a factor of 2 to 4 over using Standard Mode. However, I have read that once the deltaE is below 3 that further lowering of the deltaE is not really noticeable on the TV screen. I went back and forth between the Standard Mode and Movie Mode settings looking at various scenes. I really could not see much, if any, differences in colors between the two modes. I did have a strong preference for Native Colorspace over Auto Colorspace. I am not alone on this. I looked back at ten settings that people had previously posted on this thread for their TV. Five of the ten people were using Native rather than Auto. I prefer Native because on BD movies the picture seems a little bit sharper with objects having a more clearly defined edge. I looked up "Samsung Native mode" on the Samsung forum. According to Samsung, the Native mode is supposed to allow the use of colors outside the normal band used in BD movies and the colors can be more saturated. If that is true, there really should not be any difference between watching a BD movie in either auto or native mode. However, I see a clear difference as apparently five other people have as well. Curious.
PlasmaPZ80U, I hope the above answers your questions. If you would like to see the settings for the five scenarios I have attached the spreadsheet.
