I hate to break up the long string of complaining about how “garbage” this TV is, but can we talk about some picture settings?
More specifically, HDR. I’ve been doing a ton of testing and fiddling with settings. I think Vizio’s recommended backlight setting of 50 is not the way to go, at least for HDR10 content. It is stated that during HDR, the backlight is maximized by default, and raising it does nothing but raise the gamma curve, which washes out the image.
I think this does apply during Dolby Vision but HDR10 seems to act differently. For starters, I’m using a P55 F1. I’ve noticed that HDR10 looks pretty good but doesn’t “pop” anywhere near the level of Dolby Vision, as far as HDR highlights and general depth.
Taking a still image of a lantern in the middle of a dark room, I began going through all the settlings one by one, to try and maximize contrast. I have noticed that raising the backlight from 50 to 100 effectively doubles the brightness of the lantern. If the backlight was maximized at 50, theoretically the lantern should have stayed the same brightness, while the surrounding shadows became more gray due to the gamma curve being raised. This did not happen. Raising the backlight made the lantern pop twice as bright, while retaining the inky blacks in the surrounding image.
With this new setting of 100, it feels much more like what a 1,000 nit television should look like. Moving on to the local dimming options... I’ve gone back and forth between the medium and high settings during various scenes. It seems that sometimes medium scenes look brighter, but during some of the the scenes, the high setting seemed to make HDR highlights a bit brighter. After running the “white circle” local dimming test, I ended up settling on the medium setting, as it was able to keep the white circle the brightest as it moved across the screen, along with less flicker.
Another setting I discovered which was able to squeeze out a tad more brightness is the “black detail” setting. Switched from “off” to “medium”, I was able to make the lantern in a dark room shine just a bit brighter. This of course did make some of the dark areas of the screen a bit brighter as well, but overall I don’t feel like it ruined the overall contrast, and seemed like a net positive gain in image quality. This of course comes down to personal preference, but I like it set to medium.
If someone would like to test my settings on their display, I’d be genuinely curious to hear your results. I imagine the results could vary depending on what you use to view content. I avoid using the built in apps, since my TV has constant “you don’t have the bandwidth to stream 4K” interruptions. I have gigabit internet mind you... So I view the majority of content using an Xbox One X, which I understand may treat HDR differently than say an Apple TV. Nonetheless, here are the settings I am finding most enjoyable during HDR10 playback.
Backlight - 100
Brightness - 50
Contrast - 50
Color - 55
Sharpness - 10
Local Dimming - Medium
Black Detail - Medium
Reduce judder - 2
Reduce Motion blur - 2
Clear Action - Off
Film mode - On
Gamma - 2.2
...and I believe that’s it.
So far as I’ve been able to tell, viewing Dolby Vision content through the native Netflix and VUDU apps, the backlight control seems automated like it should be.
For all you gamers out there, if you’re on an Xbox One X, do yourself a favor and try the 120hz setting. With port 5 and a 120hz input, input lag is reduced to just 10ms. It feels incredible! The resolution is reduced to 1080p, however, it still looks quite nice and is definitely worth it for competitive games.
One interesting thing to note is that 120hz signal seems to work on ports 1-4 as well. According the the Rtings review, only port 5 supports 1080p/120hz. This is not true, as I had at working on port 2. I even went into the TV’s system settings and verified it was recieiving a 120hz signal. So in theory, you could play a game in 1080/120hz HDR on port 2.
Yes I realize that games do not actually play at 120hz on the Xbox, but you can certainly feel the reduced input lag of 10ms. It is nearly as smooth and snappy as my computer monitor, but on the big beautiful Vizio screen.
Anyway, I hope there are many of you enjoying your P Series as much as I am. Have a great day.
