Samsung JU6400 LED TV Calibration Settings
We used the Movie picture mode to calibrate the JU6400. It enables most of the TV options and look great for all contents. For playing video games, use the 'Game' picture mode instead. If you find the picture too dim, increase the backlight. A 6 is for a dark room. Don't touch 'Brightness'.
'Dynamic Contrast' crushes the shadows so leave it 'Off'.
'Warm2' is the closest to 6500k color temperature. If you find the picture too yellowish, select a cooler setting. For lower resolution contents, set 'Digital Clean View' and 'MPEG Noise Filter' to 'High'. To avoid any mismatch with the source, leave 'HDMI Black Level' to 'Auto'. If you like the soap opera effect, turn On 'Auto Motion Plus'. Since this is a 60Hz TV, it will work for sources below 60fps like blu-ray.
To avoid any variation in brightness, turn Off 'Energy Saving' and 'Eco Sensor'.
For video games, 'Game Mode' has to be enabled under 'Settings' and 'General' to lower the input lag from 119ms to 26.4ms.

What do you mean by "The following color space and white balance settings are unique to each TV, so we recommend not using them."? How would I adjust this for my TV? Thanks in advance.
Each individual TV produces color slightly differently from the others. That means that the adjustments we made to the picture of the specific unit that we reviewed will not be 100% correct for another unit, even of the same model and size. They may be 97% similar, they may be 30% similar, or possibly even less.
To properly adjust these settings, you need to use a colorimeter and calibration software, which will let you see the primary color content (amount of red, green, and blue) in different shades and colors, and then adjust those accordingly. Or you can get a professional calibration done. Both options cost about $250.
What are the best settings for all round picture?
Follow our settings posted above with the 'Movie' picture mode. Adjust 'Backlight' to your preference without changing the picture quality. Also adjust the 'Color Tone' if you prefer a cooler image.
I just bought the Samsung UN75JU641DFXZA from Sam's Club. Can you tell me the best settings to optimize both sports in HD and movies in UHD? Additionally, I am not a big fan of the SOE. I watch Netflix and Prime (both 4k) on my Fire TV plugged into HDMI 3 and sports (HD) from my TWC DVR plugged into HDMI 1. Also, is there a diagram or flow showing all the settings for this set and which settings disable other settings?
We don't have such diagram unfortunately. The user manual might explain which settings affect which but not in a very simple way. The picture settings listed on this page works great for a lot of content, especially for movies. For sports, a lot of people enjoy a brighter picture so if you would prefer that too, increase the 'Backlight' setting as much as you like. To disable the SOE completely, turn Off 'Auto Motion Plus'. A low custom value (like 3) might as well smooth out things without adding the SOE. See if you like that better than the pre-defined values. If our settings appear too yellowish, change the color temperature to 'Warm 1'.
I purchased this TV as an upgrade and mostly to watch football with as well as my daytime viewing. I watch mostly everything else at night with my projector. I am having a issue with football, the ball when thrown or kicked get blurred or become choppy. Is there anything we can do to fix this? I may end up returning TV.
Check in the picture option menu if 'Auto Motion Plus' is on. If it is on, try to set it off. If you still have some problem, set it to custom and change the value for 'Blur Reduction' until you don't have anymore problem while leaving 'Judder Reduction' and 'LED Clear Motion' off.
