Here’s my personal breakdown on the picture settings.
Backlight-I found anywhere from 25-50 was good depending on the content and ambient light.
Brightness-this had the most dramatic affect on the picture quality. Too low and you lose a lot of detail in the dark, but too high and things start to look washed. I keep it around 40-45
Color- Again, even a single point will have a big difference. 50 is fairly accurate to my eyes watching content I know as a reference. (I use ESPN and NFL network because I know what team colors should look like). However, I bump it to 51 for movies because I like the highlights and use 52-53 for sports because it makes all the flash on those networks fun. If you like that vivid look but find the stock a bit aggressive, then I’d just bump it to your liking, but anything past 55 was just over saturated, especially red.
Sharpness-depends on your content. I found 10-20 helped without over sharpening.
Color temp-Normal for movies/cool for sports/computer for games
Black detail-Low or Off. I liked low on movie mode because I like low for the Xtreme Black Engine pro
Xtreme Black Engine Pro-I hate blooming in my black bars so this was easy for me. Low kept the bars black and I found a dark scene to adjust other options to help bring some detail back out of the shadows. That’s why I chose low on black detail and keep the brightness above 40. Again these are my personal preference for movies and everyday content.
Motion control-I watched a lot of football, golf, and hockey this morning. Firstly, don’t know what I did other than rub it with the microfiber, but DSE was not present and no vignettes in the corners. For motion this tv is phenomenal. The main reason I started looking for other TVs was because of how bad the 900f was with motion handling. I tried the highest setting and trails all over the place. So I was surprised not only that there no trailson this vizio, but when I went into the motion settings, they were all at zero! I love that I have all this playroom if I need it, but I don’t. I left reduce judder on 0 since I haven’t noticed any and motion blur on 0 for movies/3 for sports and clear action ON for sports
Reduce noise-0 on signal and low on block since most of my content comes from steaming. This actually made a pretty solid difference when watching Directv Now.
Game low latency-on for game mode. I can confirm 1080p 120hz works on Xbox. And don’t really care to use the ultra low latency HDMI 5 port since it can’t do HDR. To me I found the latency to be great on this TV and seeing as I use a receiver, the ARC port was just fine. Guessing it should come in about the same as the P series. Probably in the 20-30ms range for 4K HDR game mode.
Enhanced viewing angle-OFF. This basically just boosts the colors and contrast. It’s slight, but noticeable. Maybe turn it on in sports when having a party.
